Protein is one of the major macronutrients essential in human nutrition. Protein sources especially animal sourced proteins are expensive, thus much work has been carried out to explore alternative protein sources. Seaweeds, or macroalgae, are emerging as one of the alternative protein sources. They are rich in protein with an excellent amino acid profile comparable to the other conventional protein sources. Seaweed protein contains bioactive components, such as free amino acids, peptides, lectins, and phycobiliproteins, including phycoerythrin and phycocyanin, among others. Seaweed proteins have been proved for their antihypertensive, antidiabetic, antioxidant, anti-inflammatory, antitumoral, antiviral, antimicrobial, and many other beneficial functional properties. Therefore, seaweed proteins can be a natural alternative source for functional food development. This paper discusses the compositional and nutritional aspects of seaweed protein, protein extraction techniques, functional properties of various seaweed proteins, as well as their safety for new product development and functional food applications.

The aim of the study is to present and describe the alternative sources of protein, such as animal protein and plant protein, and protein metabolism. Also important is the role of protein in human health, and how important protein is for human health. This study explains the structural characteristics relating to the functional properties of proteins, and various deficiencies that are caused by the lack of protein in human health. Furthermore, a survey conducted to analyse what types of proteins are consumed by humans and how many people rely on plant protein or animal protein. Protein is important for most efficient health, homeostasis, and haematopoiesis. Getting sufficient protein can assist to hold lean muscle mass, save you anaemia and signs and symptoms of fatigue, and help a wholesome immune system. Animal supply ingredients are a terrific supply of protein, subsequently, there might be unique recognition of nutritious underutilized animal supply ingredients along with fit to be eaten insects. In this literature review, cutting-edge information on important principles in protein metabolisms such as absorption, transport, storage, utilization, and recycling are mentioned. It additionally discusses protein bioavailability and their dietary reputation assessment. Finally, the literature might be reviewed on techniques to deal with protein deficiency in human diets [1].

Proteins, sourced from both plants and animals are essential components of the human diet. In order to meet the expanding consumer expectations, preserve environmental equilibrium, adhere to ethical norms, guarantee accessible dietary choices, improve the security of food, and address prevalent protein-energy deficiency, a progressive shift towards plant-based protein sources has become important. Proteins derived from plants are capable of supplying a complete protein diet and are rich sources of many essential amino acids and vital macronutrients. The main objective of this review is to present a generalized perspective of the significance of plant-based proteins and their contribution to preserving a higher standard lifestyle for humankind. Consequently, this review thoroughly investigates the nutritional significance of plant-based proteins, their efficient techniques of extraction and processing, their impacts on dietary habits, the applications of various food byproducts as a potential source of plant proteins, and the implications on the environment. Bioactive peptides with antihypertensive, antioxidant, antidiabetic, and/or antimicrobial activity are studied collectively with the functional and biological characteristics of protein hydrolysates derived from different protein sources. Furthermore, this review underlines the scientific hurdles for upcoming research attempts and focuses on novel approaches for enhancing the bio accessibility, the ability to digest, and sensory attributes of plant proteins.

The global demand for protein is on the rise owing to the exponential increase in the world population and to meet the global protein requirements, it is imperative to seek alternative sources of proteins in farm animal feeding. Recognizing the importance of proteins and the fact that a major portion of human protein requirements is derived from livestock in the form of meat, milk, and eggs, the available protein-feeding stuff in the form of soybean meal cannot be regarded as sufficient for feeding to livestock. Oil seeds such as rapeseed meal and canola meal have a crude protein content of 30%-40% and are widely used and hence a potential alternative protein source to soybean meal. Going forward, Grain legumes such as peas, faba beans, and lupins, another alternative source of proteins have the potential to replace traditional protein feeds completely or partially such as bone and fish meals. Duckweed with a protein content of 20%-45% is another plant-based potential protein source that can be employed in livestock feeding particularly pigs owing to its huge potential as a growth promoter as evidenced by studies in pigs and piglets. Because of their nutritional qualities and possible environmental advantages, insects represent another class of alternative protein sources that have enormous potential to function as sustainable protein sources. Several insect species have been assessed for use as animal feeds; the most promising ones include the yellow mealworm (Tenebrio molitor, TM), the common house fly (MD), and the black soldier fly (Hermetia illucens, HI). Byproducts from aquaculture and fisheries are abundant in macro- and micronutrients, and their utilisation can provide fishmeal and fish oil, which can then be further adapted for use as a source of protein in animal nutrition. Employing microalgae as an alternative source of protein in animal feeding is somehow a new concept. Many nutritional and toxicological studies have demonstrated the potential of algae biomass as a valued feed supplement or substitute for conventional protein sources such as soybean meal. While these alternative protein sources in livestock feeding may serve as useful tools, parameters such as feed safety and acceptability should be monitored based on feed safety regulations.

With a growing global population, substitute protein sources, in addition to traditional animal and plant-based proteins, will be required to meet global dietary protein requirements and assure world food safety. Insects have been suggested as a substitute protein dense food source that could be produced on a more economically viable and environmentally friendly commercial scale. Edible insects as a substitute for protein for human food and animal feed are appealing due to their low greenhouse gas emissions, high feed conversion efficiency, low land use, and ability to convert low value organic byproducts into high value protein products. Edible insects must be processed and transformed into delectable dishes. Food safety can be compromised by insect toxicity, pathogen contamination, spoilage during storage, and allergies. Consumer attitudes are a major issue in the Western world, and several strategies to encourage insect consumption have been proposed. Insects present a potential sustainable food source for humans due to their high nutritive value and ubiquitous presence. Insects can provide a reliable and sustainable source of high-quality animal protein once suitable species are identified and appropriate breeding methods are developed

The recent COVID-19 pandemic drastically affected food supply chains worldwide, showing the vulnerability of food security. Efforts to develop alternative protein sources that are sustainable and can help alleviate global food shortage problems should be prioritized. Insects have been part of our diet for thousands of years and still are today, and market trends show a global increase in the number of food-grade insect producers. The global market for edible insects has been forecasted to reach US$8 billion by the year 2030. Insects are highly nutritious and have bioactive peptides with potential therapeutic effects. This review provides an overview of the consumption of insects from ancient to modern times, discusses the rationale for using insects as alternative protein sources, and presents a summary of the major insects consumed worldwide as well as a brief description of the traditional and novel technologies currently used to process insects and/or extract their nutritional components.

The substitution of animal protein for vegetable protein in foods has become increasingly demanded by consumers. In aerated food products such as ice cream, meringues, mayonnaise, and bakery products, proteins are one of the constituents responsible for sensory and technological attributes. In addition, proteins can act as surfactants in foaming systems. The protein source can influence the kinetic stability of these systems. Thus, knowing the foaming property of vegetable proteins is important to define the final application. Studies suggest that some alternative sources, such as vegetable proteins are promising in the development of foaming food formulations.

The high demand for novel and existing sustainable protein sources (e.g., legumes, insects, algae, and cultured meat) to replace the animal-based sources is becoming crucial. This change in protein consumption calls for the re-evaluation of the current methods to assess their quality and bioavailability. The two conventional scores for PDCAAS (protein digestibility-corrected AA score) and DIAAS (Digestible Indispensable AA Score) have their limitations and have not been re-evaluated and updated to address plant and novel proteins’ quality. We suggest a sensitive physiological preclinical model that can rapidly and confidently address proteins from different sources. Our model is based on the postnatal growth, a major parameter for development and health in children, that influenced by environmental nutritional and lifestyle factors. Our results demonstrate that, with an appropriate amount of protein in the diet, almost all tested proteins performed as well as casein, the animal source. However, upon restriction (10% of calories), all alternative sources did not accomplish normal growth performance. Surprisingly, when compared to PDCAAS and DIAAS parameters obtained from the literature, no correlations were found between growth performance and these parameters, demonstrating their limitations.

There is an urgent need for alternative protein sources due to the rapid population growth, climate change, environmental degradation by pollution, food-fuel competition and the reduction in arable land for agricultural use. Conventional livestock production is also deleterious to the environment due to the production of greenhouse gasses and ammonia. This article provides insights into the potentials of edibleinsects as novel food ingredients. The manuscript provides concise explanations for the need of embracing additional protein sources, edibleinsects consumption and their nutritional benefits and environmental and economic advantages of using edibleinsects as food. Literature was gathered through an online search on the Science Direct database and Google Scholar, relevant papers published between January 2002 and November 2020 were cited. Edibleinsects are good source of essential nutrients. They are rich in proteins and essential amino acids, contain good quality lipids and significant amounts of important minerals. They are potential source of proteins for humans and animals. They can play an important role in global food security by providing essential nutrients to the increasing global population. This can only be achieved when more attention is given to their production and processing. Creating awareness among new consumers on their nutritional and environmental benefits and the development of food products with appealing sensory properties will surely improve their acceptance as food.

Abstract With the earth’s population growing, the demand for nutrition, including protein sources, also rises. An alternative to the conventional protein sources is proposed in the form of Chlorella-based protein. However, its protein extraction is hurdled by its rigid cell wall nature. This review discusses studies on improving the protein recovery level for various Chlorella species using extraction methods, including bead milling, chemical treatments, or enzymatic extraction. In addition, advanced techniques such as Three-Phase Partitioning (TPP) and its combination with enzymatic hydrolysis are briefly discussed.

The studies reported in this thesis were carried out to evaluate the effects of enzyme treatment on the nutritive value of three lupin species (L. luteus, L. albus and L. angustifolius) and evaluate their suitability as a source of protein for growing broilers. Some preliminary in vitro work on the effect of quinolizidine alkaloids on bacteria from poultry excreta was carried out. Furthermore the use of near infrared spectroscopy (NIRS) as an alternative technique for assessing the chemical composition and nutritive value (such as metabolizable energy and digestibilities) was investigated. Compositional analyses of the various lupins, fractions and diets were conducted. The chemical composition of the lupin seeds used in this study showed a high crude protein content and a variable content in ether extract and neutral detergent fibre. The alkaloid content of the seeds was determined and allowed the classification of the lupin into bitter (L. luteus cv Cardiga), semi-sweet (L. albus cv Estoril) and sweet (L. albus from France and L. angustifolius from Australia) seeds. Alkaloids from lupins decrease feed consumption and may affect the digestive capacity of the animal. A preliminary study on the effects of sparteine and alkaloids extracted from L. luteus seeds on bacteria from poultry excreta indicated that extracts of alkaloids from L. luteus had an inhibitory effect on coliform growth that was not, however, as great as that of sparteine. Sparteine, essentially prevented growth of coliforms at concentrations of 10 g dm-3. Lactobacilli were apparently not directly affected by the lupin extract of alkaloid or the isolated sparteine. This in vitro work suggests that it may be possible to influence the gut microflora in a beneficial manner by using the appropriate concentration of the appropriate alkaloids. A set of tube feeding experiments (by gavage) were carried out to evaluate the effect of different enzymes on the nutritive value of L. luteus (cv. Cardiga) and L. albus (cv. Estoril) seeds. The first experiment was a preliminary one which allowed the modification of the tube feeding assay in order to suit the characteristics of the test materials used in this study. The following six experiments tested the effects of pre-incubation, as a wet mash, of a polygalacturonase, five proteases, a pectinase and an [Special character omitted]-galactosidase at variable levels, on the nutritive value of L. luteus (cv Cardiga) and L. albus (cv. Estoril). The nutritive value of the lupin seeds was evaluated essentially by measuring metabolizable energy (ME) and amino acid (AA) digestibilities. Results indicated that L. albus seeds, irrespective of enzyme treatment, had a higher ME expressed as TMEn than L. luteus seeds. Carbohydrase containing enzyme preparations, caused variable improvements in the ME value of lupin seeds. Polygalacturonase caused a significant increase in the ME of L. luteus seeds, which may have been mediated by an increase in protein digestibility as shown by improvements in the AA digestibility. Increased concentrations of pectinase tended to be more effective in the improvement of ME of L. albus, while increasing concentrations of a-galactosidase were so for L. luteus. The fact that the carbohydrases acted differently upon the two lupin species was probably due to their different concentration in constituent carbohydrates. Pre-incubation with exogenous proteases decreased the ME of the lupin seeds. The reasons for the depression were not clear, however high concentrations of proteases, expressed as U kg-1 of lupin seeds, may have interfered with the gastro intestinal tract and also with the endogenous enzymes of the bird resulting in reduced utilisation of the pre-incubated material. A growth experiment was design to investigate the effects of the inclusion of L. luteus (cv. Cardiga), L. albus (from France) or L. angustifolius (from Australia) as the main or secondary source of protein in diets for growing broilers. Lupin seeds were either pre-incubated as a wet mash, or the lupin containing diets were supplemented with a carbohydrase, a protease or a mixture of both. Diets were fed to the animals over a three week period. The results obtained tended to support the hypothesis that the enzymes had little effect on the other dietary ingredients but had their main effects on the lupins in the diets.

This investigation was conducted in the rural community of Cuambo, located in the northeast of Imbabura province, in the Mira river basin of Salina parish, at 1530 meters above sea level and with an average temperature of 19 C. The principal objective of this investigation was to evaluate the effect of four levels of substitution of fish meal for earthworm meal in broiler chicken diets. The fieldwork occurred in two stages over the course of 20 months: A. Creation of the feed: This step lasted from the installation of an earthworm culturing area through the cultivation, harvest, and drying of the worms until obtaining the flour and then the feed with the respective formulas and acquisition of primary materials. B. Cultivation of broiler chickens: This was carried out in a community member's house adapted to function like a chicken coop that had been previously prepared to receive the chicks. The study lasted 7 weeks. A completely random design (CRD) was used with five treatments and five repetitions per treatment, with five chickens per experimental unit. ANOVA, Tukey analysis at 5%, and orthogonal polynomial analysis were used to evaluate the data. The factor under study was the percentage of earthworm flour in a basic diet. The treatments were as follows: T0: Control (Pronaca commercial feed) T1: 100% earthworm meal T2: 75% earthworm meal T3: 50% earthworm meal T4: 25% earthworm meal Analyzed variables: Weekly weight gain, Weekly food conversion, Accumulated food conversion, Total food consumption, Efficiency index, Yield, Organoleptic analysis, Economic analysis. From the results obtained, we conclude that treatment 0 (T0) is the best because it gave the best results in weight gain, food conversion, efficiency index, yield, and cost of production. In the organoleptic analysis T4 received the most points for appearance and flavor; T3 received the most for color, smell, and texture. The treatment with greatest acceptability was T4, with the most points. In production costs, the least expensive was T1, but it is not recommended for use because the chickens had poor results in the studied variables.

Previous issue date: 2013-02-19<br>Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>Current analysis evaluates the inclusion effect of feather meal in diets with and without aminoacids supplementation on the performance, centesimal composition, hematological parameters and feeding costs of Nile tilapia fingerlings, Oreochromis niloticus. One thousand and four hundred Nile tilapia fingerlings, initial average weight 4.98±0.08 g, distributed in 28 small cages of 1m³, with 50 fish each, were used. Three levels (8, 16 and 24%) of hydrolyzed feather meal (FM) inclusion and two groups, one with and the other without synthetic aminoacids supplementation (AAs), were evaluated during 65 days. Control treatment with neither feather meal nor aminoacids supplementation was also employed, totalizing seven treatments and four replications. Productive performance analysis including total length (TL), weight gain (WG), apparent food conversion (AFC), survival (SU), condition factor (CF) and protein efficiency rate (PER) was performed at the end of the experiment, coupled to body parameters such as visceral fat index (VFI) and hepatosomatic index (HIS). Blood samples were collected for erythrocytes counting and determination of hemoglobin, hematocrit, average corpuscular volume (ACV) and average corpuscular hemoglobin concentration (ACHC). The entire fish was used for the analysis of centesimal composition, namely, moisture (MO), protein (P), ether extract (EE) and mineral matter (MM)). Diet costs per kilo of WG were also assessed. Treatments did not influence (p>0.05) SU, HIS, CF, MO and MM and best results for FM and WG were those of treatments with 8% FM with or without AAs supplementation. AFC was higher and PER lower in treatments with 24% FM without supplementation. P rate was lower in treatment with inclusion of 24% FM without supplementation when compared to control, whereas EE had higher levels of inclusion when compared to control. Hematologic parameters were kept within the species´s normal variation level. Treatment with 8% FM with supplementation presented lower feeding costs. Results show that feather meal may be used in diets for Nile tilapia up to 8% inclusion, with or without supplementation of AAs, without any liability in performance, chemical composition and higidity. In fact, supplementation at the above inclusion level with AAs is economically more viable<br>Esse estudo teve por objetivo avaliar o efeito da inclusão de farinha de pena em dietas com e sem suplmentação de aminoácidos sobre o desempenho, composição centesimal, parâmetros hematológicos e custos de alimentação de alevinos de tilápia do Nilo Oreochromis niloticus. Para isso, foram utilizados 1.400 alevinos de tilápia do Nilo com peso inicial médio de 4,98 ± 0,08 g distribuídos em 28 hapas de 1 m³ com 50 peixes cada. Durante 65 dias foram avaliados três níveis de inclusão de farinha de pena hidrolisada (FP) (8, 16 e 24%) e dois grupos, um com e outro sem suplementação de aminoácidos sintéticos (AAs). Além disso, foi utilizado um tratamento controle, cuja dieta não continha nem farinha de pena e nem suplementação de aminoácidos, totalizando sete tratamentos com quatro repetições. Ao final do experimento foram realizadas análises de desempenho produtivo (comprimento total (CT), ganho de peso (GP), conversão alimentar aparente (CAA), sobrevivência (SO), fator de condição (FC) e taxa de eficiência proteica (TEP) e dos parâmetros corporais, (índice de gordura visceral (IGV) e índice hepatossomático (IHS)). As mostras de sangue foram coletadas para contagem de eritrócitos e determinação de hemoglobina, hematócrito, volume corpuscular médio (VCM) e concentração de hemoglobina corpuscular média (CHCM). Foram utilizados peixes inteiros para a análise da composição centesimal (umidade (UM), proteína (PB), extrato etéreo (EE) e matéria mineral (MM)). Também foi avaliado o custo das dietas por quilo de GP. Os tratamentos não influenciaram (p>0,05) na SO, IHS, FC, UM e MM. Os melhores resultados de PF e GP foram dos tratamentos com 8% de FP com ou sem suplemetação de AAs. A CA foi maior e a TEP menor no tratamento com 24% de FP sem suplementação. A PB foi menor no tratamento com inclusão de 24% FP sem suplementação em relação ao controle, e o EE aumentou com níveis mais altos de inclusão em relação ao controle. Os parâmetros hematológicos mativeram-se dentro da faixa de variação normal para a espécie. O tratamento com 8% de FP com suplementação apresentou o menor custo de alimentação. Conclui-se que a farinha de penas pode ser utilizada em dietas para tilápia do Nilo em até 8% de inclusão, com ou sem suplementação de AAs, sem prejuízos no desempenho, composição química e higidez, sendo que a suplementação deste nível de inclusão com AAs é economicamente mais viável

Ethanol yeast (EY) is a single-cell protein obtained as a co-product during the production of fuel ethanol and may have potential as an alternative protein source for rainbow trout. The objective of the current study was to determine if EY could replace fish meal (FM) without negatively impacting growth performance of juvenile rainbow trout. Three experiments were conducted to evaluate the use of EY. In Exp. 1 a digestibility trial was done to determine EY apparent digestibility coefficients (ADCs) for protein, lipid, energy, DM, and apparent availability coefficients (AACs) for amino acids. In Exp. 2 a feeding trial was conducted where a control diet (42% digestible protein and 20% crude lipid) was compared to diets where FM digestible protein was replaced by EY at varying levels (25, 37.5, 50, 62.5, 75, 87.5, and 100%). Diets were fed twice daily to rainbow trout to apparent satiation in a 15°C recirculating system. There were 4 replicate tanks per diet (30 fish/tank). Experiment 3 was conducted to determine if a mycotoxin inhibitor (Biofix Plus) could improve performance of rainbow trout when fed higher levels of EY. The experiment was a 2x3 factorial where FM was replaced with EY (0, 50 and 100%) with or without Biofix Plus. There were three replicate tanks per diet (15 fish/tank). Results from Exp. 1 showed that Ethanol yeast ADCs for protein, DM, lipid, energy and AAC for and sum of amino acids were quantified at 98, 65, 100, 70, 81 and 81%, respectively. Results from Exp. 2 showed that fish growth was not different from the control diet at the 25% and 37.5% replacement levels. However, reduced growth (P < 0.001) and poorer feed conversion (P < 0.001) were measured when EY replaced more than 37.5% of dietary FM (11.2% EY inclusion). Results from Exp. 3 found no effect of Biofix Plus on performance of rainbow trout. There was reduced growth (P=0.001) in the 50 and 100% replacement diets. Apparent digestibility coefficients suggested that EY nutrients were highly digestible. However, growth was reduced at EY inclusion levels that were greater than 11.2%.

Aquaculture production is increasing annualy and wild fisheries for fishmeal production remain stagnant. As a consequence, extensive research has been deployed to reduce dietary fishmeal inclusion in feeds of farmed species. Usage of alternative protein sources derived from plants continues to increase with the most popular sources being oilseeds, legumes and cereal grains. The downside of these sources is that most of them could directly be used for human consumption arising legitimate criticism from voices referring to countries where protein shortages lead to malnutrition among the population. Jatropha curcas is a tropical oilseed with upcoming popularity for sustainable fuel sourcing. The plant is thought to thrive in semi-arid and arid areas, not just producing oil, but at the same time reclaiming previously eroded land for the local population. For these reasons, annual cultivation of Jatropha curcas is thought to rise over the next decades. After oil is extracted from the seed, the remaining press cake, is currently used as a fertilizer or energy source. This is mostly due to toxic phorbol esters that until recent- ly limited any nutritional applications. In 2011, a method to detoxify Jatropha press cake was developed and paved the way for nutritional research on the resulting detoxified Jatropha curcas kernel meal (JKM) to be launched. JKM offers very high protein content with a balanced amino acid composition suggesting opportunities for usage as a feedstuff in aquaculture diets. JKM further has higher mineral content than comparable oilseeds. However, potential anti-nutritional factors (ANFs) present in the meal could lead to impairment of nutrient availability or other adverse effects. Previous research has already started to evaluate JKM as a protein source for a variety of aquaculture species. This thesis attempts to further identify the potential of JKM as a protein source and assess the effects of JKM on the development of two model cultured teleost species, common carp (Cyprinus carpio) and Nile tilapia (Oreochromis niloticus), as they represent two of the most farmed species, particularly in the tropics. The work comprises growth trials on both species using fishmeal as a subject of replacement in solely fishmeal protein-based diets and on more practical fishmeal/plant protein-based diets. It engages with the effects of phytate, a prominent component of JKM with potential anti-nutritional attributes and commercially available phytase feed supplements to diminish these attributes, as well as oxalate, another plant-specific component with high concentrations in JKM and with limited attention in aquaculture nutrition research. Carp and tilapia showed varying results with different inclusion levels of JKM. For carp 50% fishmeal replacement was possible without losses in growth in diets where fishmeal was the only bulk protein source (Chapter 3.1), Tilapia showed slightly worse growth at a 30% replacement level (Chapter 3.2). A steep decline in growth could be observed when replacing 100% fishmeal with JKM in carp (Chapter 3.1), while tilapia showed no difference at that level compared to 30% replacement (Chapter 3.2). In practical diets, 100% of fishmeal could be replaced by JKM without any adverse effects on growth of carp (Chapter 3.3), while tilapia showed a slight, but significant linear negative correlation with higher inclusion levels of JKM (Chapter 3.4). Phytase addition in tilapia feeds was identified as having no obvious impact on growth in JKM based diets where enough available phosphorus was provided through mineral supplementation (Chapter 4.1). In JKM based diets where available phosphate was not added, phytase addition showed a tendency to increase growth and significantly increased mineral retention and decreased phosphorus effluent contamination (Chapter 4.2). Phytase application through pre-incubating JKM along with citric acid exerted a positive effect of growth on carp when fishmeal protein was replaced by 50% (Chapter 3.1). Phytase was further shown to completely hydrolyze phytate in vitro; however, incomplete hydrolysis was observed in vivo in tilapia (Chapter 4.3). Dietary soluble oxalate added to fishmeal based diets for carp showed better growth parameters, nutrient and mineral retention at inclusion levels 1.5% and higher (Chapter 5.1). For tilapia, a trial could demonstrate adverse effects of oxalate on potassium, calcium, manganese and zinc digestibilities, in this case without negative effects on growth (Chapter 5.2). For both, carp and tilapia, an impact of oxalate on lipid metabolism was evident, lowering body lipid content and blood cholesterol in inclusion levels from 1.5% or higher. JKM can become a valuable alternative to present dietary protein sources in aquaculture feeds. The nutritional attributes of JKM need further research, especially longer-term testing in a commercial scenario and application in commercially produced feeds. Results of this thesis pose a useful addition to previous research and can be referred to for realizing these next steps.

As global meat consumption is rising, the negative impact the animal husbandry sector has on the environment will increase. Greenhouse gas emissions have increased by 40 % during the last 200 years, and the animal husbandry sector is today responsible for 18 % of the total greenhouse gas emissions from food production. More environmentally friendly protein sources, such as soy and pea, must therefore be developed. Pisum sativum can (unlike the most popular meat alternative – soy) be grown all over Europe and might thus be a good alternative that allows for locally sourced alternatives to meat protein. Identifying genes with important agricultural properties might aid the development of pea cultivars with a more reliable protein content. One such gene was hypothesised to be the OMT gene, which is strongly expressed during the embryonic development of P. sativum and seems involved in functions such as seed storage and protein synthesis. Thirty-one accessions of P. sativum were tested to see if different improvement types differed from each other regarding protein content and seed weight, but no such differences were found. DNA was extracted from all accessions, sequenced, and successful sequences were tested to determine if variation in the gene correlated with protein content. Two haplotypes were identified, but there was no correlation between them and protein content found. Based on the results of this study, there is little evidence that the OMT gene correlates with protein content in the studied accessions.

In the food industry, protein sources play a crucial role in human nutrition. Traditionally, animal sources such as meat, dairy products and eggs have been recognised as the main source of protein, but plant protein sources are also receiving increasing attention. In this context, cereals such as maize and sorghum are considered as important vegetable protein sources. Maize is one of the most widely produced cereals worldwide and is an important source of protein. Although maize is low in lysine, one of the essential amino acids, it can be combined with other grains to make it a balanced protein source. Sorghum, like maize, is a low-cost protein source and can be grown in challenging conditions such as scarcity and drought. The high protein content of sorghum plays an important role in bridging the protein gap, especially in developing countries. Additionally, sorghum contains components with antioxidant properties, which are important for health benefits. Grains like maize and sorghum are rich in protein and economically accessible sources, holding significant potential to meet the protein needs in human nutrition and ensure food security. Therefore, research and applications to increase the protein content of these cereals will continue to play an important role in nutrition and agriculture in the future.

Protein, a vital macronutrient composed of amino acids performs various important functions ensuring a healthy life. Proteins have been derived traditionally from animals and plants such as meat, seafoods, eggs and from legumes, seeds, nuts, and cereals respectively. Plant-derived proteins are cheaper and more sustainable than animal-derived proteins. The world’s population is increasing astonishingly to a high level. We have to increase our food production by twofold by 2050. Food scientists should take the enhancement of protein production as a serious challenge. There is a need to utilize the full potential of traditional protein sources and discover novel methods and alternative techniques of healthy dietary protein production. Emerging protein sources and alternatives to plant-based and animal-based proteins like insects, microbes, and plant-based alternatives are gaining much attention from food developers. This study involves a comparative analysis of plant-derived and animal-derived proteins. The current study aims to investigate the utilization of the potential of traditional protein sources and to develop emerging protein sources to take a step toward global food security. The goal is to open the gateway for researchers to work further and develop potential protein sources.

Orthoptera is an order of insects that includes grasshoppers, crickets, katydids, and locusts. These insects are characterized by their large hind legs, adapted for jumping, and their ability to produce sound (stridulation) by rubbing certain body parts together. Certain species of grasshoppers can undergo a phase change to become locusts, forming large swarms that can travel great distances and cause significant agricultural damage. The sound produced by crickets and katydids is species-specific and is used to attract mates. Each species has a unique song. Many Orthopterans have evolved to blend into their surroundings to avoid predators. Some resemble leaves, sticks, or even bird droppings. While many Orthopterans are beneficial as they help in controlling weed growth, some, particularly locusts, can be major agricultural pests. Grasshoppers are increasingly recognized as a sustainable and nutritious protein source. Here are some key points regarding the protein content and nutritional benefits of grasshoppers, grasshoppers typically have a high protein content, ranging from 60-70% of their dry weight. This is comparable to or even higher than traditional protein sources such as beef and chicken. The protein from grasshoppers contains all essential amino acids required by the human body, making it a complete protein source. Besides protein, grasshoppers are rich in important micronutrients, including vitamins (such as B vitamins) and minerals (like iron, zinc, and magnesium). They have a low carbohydrate content, which can be beneficial for those on low-carb diets. Grasshoppers contain chitin, a form of dietary fiber that can aid in digestion. Farming grasshoppers requires significantly less land, water, and feed compared to traditional livestock. They also produce fewer greenhouse gases. Grasshoppers have a high feed conversion efficiency, meaning they convert feed into body mass more effectively than traditional livestock. Grasshoppers can be roasted, fried, or boiled and eaten whole, often seasoned for flavor. They can be ground into a powder and used as a protein supplement in various foods, such as smoothies, protein bars, and baked goods. Grasshopper flour can be used as a high-protein, gluten-free alternative in cooking and baking. It’s important to ensure that grasshoppers are sourced from safe and controlled environments to avoid contamination and pesticide exposure. Proper cooking is necessary to kill any potential pathogens and make the grasshoppers safe for consumption. In many cultures around the world, especially in Africa, Asia, and Latin America, grasshoppers are a traditional food source and are commonly consumed. With the growing interest in sustainable and alternative protein sources, grasshoppers are gaining acceptance in Western countries as well. In summary, grasshoppers offer a highly nutritious and environmentally sustainable protein source. They can be incorporated into various diets and culinary practices, providing a valuable alternative to traditional animal proteins.

Proteins, essential compounds containing carbon, hydrogen, oxygen, and nitrogen, are synthesized through peptide bonds between amino acids. Recognized in the 18th century, proteins’ significance in nutrition and biology was established by early hypotheses from scientists like Gerhardus Johannes Mulder and Berzelius. Proteins consist of 20 amino acids, categorized into essential and non-essential. Non-essential amino acids, such as glutamine, glycine, and cysteine, are synthesized by the body and support crucial functions like cell growth and metabolism. Essential amino acids, including phenylalanine, threonine, and branched-chain amino acids (BCAAs), must be obtained from the diet and are vital for protein synthesis. BCAAs are significant in muscle metabolism and have shown health benefits in studies, including muscle mass preservation and mental health improvement. Projected global population growth to 9.7 billion by 2050 emphasizes the need for diverse protein sources. High-quality animal proteins, like those from eggs, meat, milk, and fish, are efficiently converted into body proteins. Plant proteins, though slightly less digestible, remain essential for sustainable nutrition. Protein quality is assessed using methods like the Protein Digestibility-Corrected Amino Acid Score (PDCAAS) and the newer Digestible Indispensable Amino Acid Score (DIAAS). Despite DIAAS being more accurate, PDCAAS is still widely used due to data limitations. Surveys in Türkiye show higher protein intake in males compared to females. The Recommended Dietary Allowance (RDA) for protein is 0.8 g/kg of body weight, with variations across age and gender. Ensuring adequate protein intake is critical for health, as shown by varying nutritional statuses, especially in older populations, underscoring the importance of diverse protein sources.

Protein in fish feed is one of the most important nutrients for the healthy growth and development of fish. Protein sources are divided into two main groups: animal and plant. Animal proteins are of high quality and contain all the amino acids that fish need. Vegetable proteins, on the other hand, are cheaper and sustainable. Historically, fish meal and oil were given to both carnivorous and herbivorous fish when they were juveniles to meet their high protein needs. However, due to excessive use, sustainability concerns have arisen, and alternative protein sources have begun to be investigated.

Proteins form the structure of the smallest part of the body, the cell, and the enzymes that catalyse metabolic processes. Approximately 21% of the protein obtained from various sources comes from wheat, which is of strategic importance and created to be suitable for human nature. Wheat, especially durum wheat kernels, contains an average of 8-14% protein, but this ratio is significantly affected by environmental conditions. In particularly, soil nitrogen levels and weather conditions during the grain filling period, in interaction with the genotype, are closely related to the protein content of wheat. The quality of gluten, an important protein component used in bread making, is largely influenced by the genotype. The effect of genotype-environment interaction on gluten quality varies among different genotypes. Correctly interpreting the genotype-environment interaction that affects protein content and quality can enable the development of stable varieties with suitable protein quality and content.

Alternative protein sources have emerged as a significant topic from an agricultural perspective. Alternative protein sources include alternative plants, algae, fungi, insects, microbial proteins, in vitro or artificial meat, dairy-free vegan cheese, and other products produced through technologies such as biofermentation. The integration of alternative protein sources into agricultural production systems is seen as an important step towards a sustainable food system. This integration not only helps reduce environmental impacts but also plays a key role in meeting the protein needs of the growing global population in the future. This study was prepared to reveal the agricultural importance of alternative protein sources. In conclusion, considering global developments, it can be said that sooner or later insect-fortified foods, food ingredients, or cosmetic products will enter our lives. Therefore, urgent efforts are needed to start religious, scientific, and industrial studies to solve this current issue from an Islamic perspective.

Abstract Carbon steel pipelines are employed in the transportation of wet natural gas from source to process plant. Corrosion and formation of hydrates is an important threat to the integrity of the pipeline if not properly controlled. In order to protect pipelines from hydrate formation, Monoethylene glycol (MEG) is often used. The continuous use of pH stabilizers in natural gas pipelines can lead to the formation of desirable and undesirable scale formation. If the use of pH stabilizers gives negative effects due to the formation of unwanted scale, the increase in the pH of the system is no longer effective and corrosion rates may increase. Alternatively measures may be introduced to maintain the integrity of pipelines such as the use of corrosion inhibitor. This paper investigates conditions where there is a significant formation of corrosion scale in the form of iron carbonate in wet gas systems. The continuous use of high pH at certain points of the pipeline is reconsidered with a focus on the formation of scale. The effect that lowering the pH of the solution has on the corrosion rate and existing protective corrosion product is evaluated. Synergistic and antagonistic effects of MEG with iron carbonate scale are determined with particular considerations of the use of alternative corrosion protective methods at reduced pH.

In the REPowerEU strategy, the European Commission proposes accelerating renewable hydrogen production by 2030 to produce more affordable, safer, and sustainable energy. Hydrogen energy has significant potential in the future of transportation. Its many benefits include reducing pollution, diversifying energy sources, having higher energy density than batteries, and being used for long-distance or high-tonnage transport. The present article proposes an analysis of the use of hydrogen energy in transport between potential and perspectives. The benefits are highlighted, and the technologies for obtaining H2 as an energy source are presented. Depending on the source and extraction method, four methods and technologies for securing hydrogen and four main types of H2 (green, gray, blue, and turquoise) exist. Although green H2 is the only type obtained with zero polluting gas emissions, the most widespread is gray H2 (from natural gas or waste coal) - 96% today. The main applications of hydrogen in transport are presented: 1. Road-Fuel Cell Vehicles (FCEVs) that offer zero emissions and range similar to vehicles with conventional engines and short recharging time. 65% of buses must be zero-emission by 2025 and 30% of trucks by 2030. The Mercedes-Benz city bus runs entirely on energy from two sources - state-of-the-art electric batteries and hydrogen-based fuel cells, which protect the energy supply on the road - without intermediate charging. In cars, Toyota's Fuel Cell System is one of the most advanced technologies in the field. 2. Rail�Hydrogen use in rail vehicles offers a clean alternative to diesel or electric locomotives, significantly reducing gas emissions. Alstom's Coradia iLint, manufactured in 2016, is the world's first passenger train powered by fuel cells and H2. 3. Maritime transport�Hydrogen fuel cells can propel ships or power other energy systems. The HySeas III project demonstrates that fuel cells can be successfully integrated with a marine hybrid electric propulsion system (electric propulsion, controls, batteries, etc.) and associated hydrogen storage facilities. Hydrogen ferries�Norwegian Ship Design has designed RoPax with this in mind. 4. Air transport must operate with clean energy. ZeroAvia's 19-seat twin-engine Dornier 228 aircraft completed a test flight of around 10 minutes in the UK. This article proposes an analysis of hydrogen technologies and their applications in transport, following the potential, challenges, and immediate prospects of implementation, as well as specific economic and environmental aspects.

The Growing concern about climate change and the actions that need to be taken to protect environment have begun to occupy the top places on global agenda in recent years. Transport of the future will look different: ecological, economic and maximum efficiency. But it's not only car manufacturers who are making efforts to reduce as much as possible the climate impact of vehicles. One of solutions is and the major interest of using hydrogen as a viable answer for decarbonizing industrial processes and economic sectors where carbon reduction is both urgent and difficult to achieve. Thus, a new approach to climate policy is required, the development of storage technologies and charging infrastructure, in order to have a healthier way of life and a cleaner environment. The paper presents an analysis of all aspects, from the point of view of explosion protection, for use hydrogen as an alternative fuel source, using simulation in MATLAB-Simulink of production, storage and use it. All these processes can generate critical situations, and the analysis of pressures, temperatures and other defining parameters are of major importance for the assessment of explosion risks in the context of safety and health and environmental protection, the minimum ignition energy of hydrogen being about 17 ?J.

Proteins are crucial macronutrient for human health. Animal, dairy, and some plant proteins are considered high-quality proteins that provide health and metabolic benefits based on the digestible levels of essential amino acids they contain. Animal protein is rich in many essential amino acids, but excessive animal protein intake greatly increases fat intake. Therefore, due to the improvement in people's living standards and increase in protein intake, the animal protein supply is not sufficient to meet the increasing demand of people. Technologically, milk proteins are the most important component of milk due to their unique properties that allow milk to be converted into a wide range of products such as cheese or yoghurt quite easily. It is widely accepted that dairy products are excellent sources of highly digestible essential amino acids. Nowadays, plant protein is preferred because has advantages such as it is an abundant source, cheap, easy to obtain, preferred by special consumer groups such as vegan/vegetarian, does not contain cholesterol and preventing diseases. In the last decades, the increasing interest of both producers and consumers in plant proteins and the decrease in animal protein intake and inclination to plant protein intake with the innovations in the markets emphasize the importance of these alternative sources. In this review, information is given about the importance of milk proteins and plant proteins and the role they play in consumer preference is mentioned.

The growing global population combined with the socio-economic changes leads to the increase of the demand of plant proteins for human nutrition. In recent years, many studies has been aimed at developing new high-quality and functional plant-based protein food. Lupin being a widely cultivated legume crop is one of the most promising alternative source of proteins for human nutrition. However, the scientific knowledge of the production process of proteins from lupin meal is still very scarce.In this work, different conditions of extraction and purification were evaluated for production of lupin protein isolates. The results showed that the extraction yield was comparable between acidic and alkaline pH (37% vs 40-45%) and the extracted proteins were principally composed of globulins. This finding was astonishing regarding the selective extraction of albumins in acidic pH previously reported for other plant protein sources. The ionic strength negatively impacted the protein extractability at pH 2, whereas no significant differences were observed between extraction at 20 to 50°C.The selected extraction conditions (pH 2 and 7) combined with purification by isoelectric precipitation or ultrafiltration process generated the isolate grade products. Further structural characterization of isolates revealed a partial denaturation of lupin proteins extracted under acidic pH resulting in low protein solubility at pH 6-7 (10-50%), loss in secondary structure, low thermal stability, and formation of aggregates. However, these modifications did not significantly impact the foaming and emulsifying properties of proteins. The obtained results highlighted the original and previously not described behaviors of lupin proteins observed during the isolation process. For the first time the combined effect of extraction and purification conditions on the process performances and the quality of producing proteins was shown. The presented conclusions may help to better characterize lupin proteins and valorize lupin meal as a source of plant proteins in food industry.

The UK is seeing growing interest in alternative protein sources to traditional animal-based proteins such as beef, lamb, pork, poultry, fish, eggs, and dairy. There is already an extensive market in alternative protein materials, however, technological advances combined with the pressure for more sustainable sources of protein has led to an acceleration of innovation and product development and the introduction of a large amount of new alternative protein ingredients and products to the market. These have the potential to dramatically impact on the UK food system. This report is a combination of desk research, based on thorough review of the academic and non-academic literature and of the alternative proteins start-up scene, and presents an analysis of the emerging market for alternative proteins, the potential implications and the potential policy responses that the FSA might need to consider. Four main categories of alternative proteins are presented and reviewed in this report: Plant-based meat substitutes Novel protein sources Proteins and biomass biosynthesised by microorganisms Cultured meat

The feed-food competition for environmental and economic resources raises increasing concerns about the production and supply of protein for the global livestock sector. Risks to food-security and approaching deadlines for global sustainable development, means exploring the potential for alternative protein feeds is imperative. However, as the use of alternative feeds for livestock production is still at its infancy, it is critical that potential direct or indirect food safety risks are evaluated before implementation at commercial scales. This Rapid Evidence Assessment (REA) offers a lens that focuses on the potential opportunities and threats of such alternatives for the sustainability and food safety of the global livestock sector. Four potential alternative protein sources for livestock feeds are identified and evaluated through this REA: genetically modified / engineered protein crops and alternative cultivation methods cellular agriculture former foods, food waste and industry by-products and waste streams animal by-products and insects Through this analysis, a strategic policy roadmap and research agenda are synthesised to facilitate higher-level policy making, supporting local solutions for global sustainable development and a more food-secure future. The four broad directions for policy making and research the REA proposes are: decoupling protein production from fossil fuel developing sustainable economic strategies for alternative proteins at a subnational level supporting circular livestock feed solutions further enhancing the feed and food regulatory system

This report provides an executive summary of a recent consumer poll conducted on alternative proteins. In December 2021, the FSA commissioned Ipsos MORI to conduct an online survey to understand consumer awareness and perceptions of alternative proteins. The survey was conducted with 1,930 adults aged 16-75 living in England, Wales and Northern Ireland. Data was collected between 9th – 11th December 2021 via Ipsos MORI’s online omnibus. The data was weighted to be representative of the adult population aged 16 – 75 living in England, Wales and Northern Ireland on key demographics: age, gender, region, working status and social grade.

The place of protein in sub-Saharan Africa’s food system is changing rapidly, raising complex international development, global health and environmental sustainability issues. Despite substantial growth in the region’s livestock agriculture sector, protein consumption per capita remains low, and high levels of undernourishment persist. Meanwhile sub-Saharan Africa’s population is growing and urbanising rapidly, creating expectations that demand for protein will increase rapidly over the coming decades and triggering calls for further investment in the expansion and intensification of the region’s meat and dairy sector. However, growing disquiet over the environmental impacts of further expansion in livestock numbers, and growing sales of alternative protein products in the Global North, has raised questions about the future place of plant-based, insect and lab-grown proteins in African diets and food systems. This report examines financial investment in protein production in sub-Saharan Africa. It begins from the position that investors play an important role in shaping the development of diets and food systems because they are able to mobilise the financial resources required to develop new protein products, infrastructures and value chains, or to prevent their development by withholding investment. It therefore investigates which actors are financing the production in sub-Saharan Africa of: a) animal proteins such as meat, fish, eggs and dairy products; b) ‘protein crops’ such as beans, pulses and legumes; and c) processed ‘alternative proteins’ derived from plants, insects, microbes or animal cells grown in a tissue culture. Through analysing investment by state, philanthropic and private sector organisations – as well as multilateral financial institutions such as development banks – it aims to establish which protein sources and stages of the value chain are financed by different groups of investors and to explore the values and goals which shape their investment decisions. To this end, the report examines four questions: 1. Who is currently investing in protein production in sub-Saharan Africa? 2. What goals do these investors aim to achieve (or what sort of future do they seek to bring about) through making these investments? 3. Which protein sources and protein production systems do they finance? 4. What theory of change links their investment strategy to these goals? In addressing these questions, this report explores what sorts of protein production and provisioning systems different investor groups might be helping to bring into being in sub-Saharan Africa. It also considers what alternative possibilities might be marginalised due to a lack of investment. It thus seeks to understand whose priorities, preferences and visions for the future of food might be informing the changing place of protein in the region’s diets, economies and food systems.

Cationic polypeptide proteins found in the seeds of the tropical plant Moringa oleifera have coagulation efficiencies similar to aluminum and ferric sulfates without their recalcitrant nature. Although these proteins possess great potential to augment or replace traditional coagulants in water treatment, harvesting active protein from seeds is laborious and not cost-effective. Here, we describe an alternative method to express and secrete active M. oleifera coagulant protein (MO) in Bacillus subtilis. A plasmid library containing the MO gene and 173 different types of secretory signal peptides was created and cloned into B. subtilis strain RIK1285. Fourteen of 440 clones screened were capable of secreting MO with yields ranging from 55 to 122 mg/L of growth medium. The coagulant activity of the highest MO secreting clone was evaluated when grown on Luria broth, and cell-free medium from the culture was shown to reduce turbidity in a buffered kaolin suspension by approximately 90% compared with controls without the MO gene. The clone was also capable of secreting active MO when grown on a defined synthetic wastewater supplemented with 0.5% tryptone. Cell-free medium from the strain harboring the MO gene demonstrated more than a 2-fold reduction in turbidity compared with controls. Additionally, no significant amount of MO was observed without the addition of the synthetic wastewater, suggesting that it served as a source of nutrients for the effective expression and translocation of MO into the medium.

Original objectives: To create BAC contigs covering two QTL containing chromosomal regions (QTLR) and obtain BAC end sequence information as a platform for SNP identification. Use the SNPs to search for marker-QTL linkage disequilibrium (LD) in the test populations (US and Israel Holstein cattle). Identify candidate genes, test for association with dairy cattle production and functional traits, and confirm any associations in a secondary test population. Revisions in the course of the project: The selective recombinant genotyping (SRG) methodology which we implemented to provide moderate resolution QTL mapping turned out to be less effective than expected, due to problems introduced by incomplete marker informativity. This required a no-cost one-year extension of the project. Aside from this, the project was implemented essentially as envisaged, but only with respect to a single QTLR and single population association-test. Background to the topic. Dairy cattle breeders are looking to marker-assisted selection (MAS) as a means of identifying genetically superior sires and dams. MAS based on population-wide LD can be many times more effective than MAS based on within-family linkage mapping. In this proposal we developed a protocol leading from family based QTL mapping to population-wide LD between markers and the QTL Major conclusions, solutions, achievements. The critical importance of marker informativity for application of the SRG design in outcrossing random mating populations was identified, and an alternative Fractioned Pool Design (FPD) based on selective DNA pooling was developed. We demonstrated the feasibility of constructing a BAC contig across a targeted chromosomal region flanking the marker RM188 on bovine chromosome BTA4, which was shown in previous work to contain a QTL affecting milk production traits. BAC end sequences were obtained and successfully screened for SNPs. LD studies of these SNPs in the Israel population, and of an independent set of SNPs taken across the entire proximal region of BTA4 in the USA population, showed a much lower degree of LD than previously reported in the literature. Only at distances in the sub-cM level did an appreciable fraction of SNP marker-pairs show levels of LD useful for MAS. In contrast, studies in the Israel population using microsatellite markers, presented an equivalent degree of LD at a 1-5 separation distance. SNP LD appeared to reflect historical population size of Bostaurus (Ne=5000- 10,000), while microsatellite LD appeared to be in proportion to more recent effective population size of the Holstein breed (Ne=50-100). An appreciable fraction of the observed LD was due to Family admixture structure of the Holstein population. The SNPs MEOX2/IF2G (found within the gene SETMAR at 23,000 bp from RM188) and SNP23 were significantly associated with PTA protein, Cheese dollars and Net Merit Protein in the Davis bull resource population, and were also associated with protein and casein percentages in the Davis cow resource population. Implications. These studies document a major difference in degree of LD presented by SNPs as compared to microsatellites, and raise questions as to the source of this difference and its implications for QTL mapping and MAS. The study lends significant support to the targeted approach to fine map a previously identified QTL. Using high density genotyping with SNP discovered in flanking genes to the QTL, we have identified important markers associated with milk protein percentage that can be tested in markers assisted selection programs.
