Full textAbstract:
The trade of buffalo meat is very limited in Brazil, where it is still considered exotic, and ~90% of it is marketed as cattle meat. The present study compared qualitative characteristics of the longissimus muscle from buffalo and cattle. Eighty uncastrated male bovids (40 Mediterranean × Murrah crossbred buffaloes and 40 Nellore cattle) with an average age of 21 months and initial average bodyweight of 350 kg and 305 kg respectively, were confined for 102 days. Buffalo carcass had lower dressing-out percentage (P < 0.0001; 52.1% vs 57.2%) than did cattle carcass; buffalo meat had greater fat cover (P < 0.0001; 13.8 vs 8.1 mm) and, consequently, lower cooling loss (P < 0.0001; 1.3% vs 1.8%) than did cattle meat; also had lower cooking loss (P = 0.0120; 29.42% vs 31.31%), lower collagen content (P < 0.0001; 4.81% vs 5.73%), higher moisture (P = 0.0027; 75.13% vs 74.55%), and lower atherogenicity index (P = 0.0008; 0.61 vs 0.70) than did cattle meat. There was no difference (P = 0.13) between buffalo and cattle regarding cold carcass weight (251 kg and 244.8 kg respectively). Tenderness, fat, and omega-6 : omega-3 fatty acid ratio were also similar in both meats. The buffalo carcass provides higher yield of cuts of high commercial value than does the cattle carcass; it has similar or better physical and chemical properties than beef and a lower percentage of polyunsaturated fatty acids, making it less susceptible to rancidity. Cattle meat has higher concentrations of C12:0 and C14:0 fatty acids, which are related to increased serum low-density lipoprotein and cholesterol concentrations, while buffalo meat is a rich source of C18:0 and C18:1n9c fatty acids, which help in the prevention of cardiovascular diseases.

The aim of this study was to evaluate the effects of different aging times on the meat characteristics from young Murrah buffaloes slaughtered at 20–24 months of age (experiment I; n=10) and Murrah buffalo heifers slaughtered at 32-36 months of age (experiment II; n=10), with the purpose of determining the best aging time to tenderize meat from both experiments. Samples of the longissimus thoracis muscle from buffaloes slaughtered at each age were aged for 7, 14, and 21 days (0±1°C). After this period, analysis of cholesterol, pH, cooking loss, shear force, myofibrillar fragmentation index, meat color, and fatty acid profile was performed. Aging greatly improved the tenderness (p < 0.05) but caused a change in color (p < 0.05), which, even without difference between the treatments for subjective perception of the color (ΔE; p > 0.05), was considered very noticeable to the human eye. Furthermore, aging reduced the polyunsaturated fatty acids (p <0.05) and did not affect the levels of cholesterol (p > 0.05) in the meat of young buffalo and buffalo heifers of advanced age. Based on the evaluated meat characteristics, concludes that seven days of aging are sufficient for older buffalo heifers, but 21 days of aging are required for the younger male group.

<p>Five (5) mixtures of buffalo / pork meat (70/0, 52.5/17.5, 35/35, 17.5/52.5 and 0/70), maintaining stable the amount of pork backfat, were prepared and analyzed for their chemical composition, fatty acids profile, instrumental parameters and sensory attributes. The results of the study showed that the addition of buffalo meat produced sausages with higher protein and less fat content. A slight decrease in ?6/?3 ratio was observed and an increase in CLA fatty acids. Principal Component Analysis revealed that the lower fat content in the sausages the higher the levels of CLA18:10trans 12cis and CLA18:9cis 11trans, whereas, SFA is abundant at the highest fat levels. Redness and hardness instrumentally increased in the sausages with the addition of buffalo meat, while juiciness decreased, probably due to the decreased lipid content. The mixture with the ratio of 52.5/17.5 buffalo/pork positively maximized sensorial consistency, elasticity and cohesiveness of the traditional sausages, while the addition of 70.0/0.0 mixture, hardness and redness.</p>

Abstract Carcass and meat quality of male and female Anatolian water buffaloes were investigated using 10 carcasses from each gender. Gender had no influence on carcass characteristics, except warm carcass weight, which was 13% higher in males compared to females. Meat from male water buffaloes had higher ultimate pH and lightness (L*), but lower redness (a*) values than females. Meat samples aged for 21 days had lower values for expressed juice, cooking loss and Warner Bratzler shear force compared with those of 7-day aged ones. Meat samples aged for 21 days had higher L* value at 1 h and 24 h after cutting, a* value at 1 h after cutting compared with those of 7-day aged meat samples. Gender had no effect on meat sensory characteristics. Meat from male water buffaloes had higher proportions of C14:0, C18:3 n-3, C20:2 n-6, C20:3 n-3 and C20:4 n-6 and Σn-3 fatty acids and lower Σn-6/Σn-3 ratio compared with female water buffaloes.

Full textAbstract:
The effects were assessed of two energy sources in concentrate (ground grain corn vs. citrus pulp) and two nitrogen sources (soybean meal vs. urea) on rumen metabolism in four buffaloes and four zebu cattle (Nellore) with rumen cannula and fed in a 4 × 4 Latin square design with feeds containing 60% sugar cane. Energy supplements had no effect on the rumen ammonia concentration in cattle, but ground grain corn promoted higher ammonia level than citrus pulp in buffalo. Urea produced higher ammonia level than soybean meal in both animal species. On average, the buffaloes maintained a lower rumen ammonia concentration (11.7 mg/dL) than the cattle (14.5 mg/dL). Buffaloes had lower production of acetic acid than cattle (58.7 vs. 61.6 mol/100 mol) and higher of propionic acid (27.4 vs. 23.6 mol/100 mol). There was no difference in the butyric acid production between the buffaloes (13.6 mol/100 mol) and cattle (14.8 mol/100 mol) and neither in the total volatile fatty acids concentration (82.5 vs. 83.6 mM, respectively). The energy or nitrogen sources had no effect on rumen protozoa count in either animal species. The zebu cattle had higher rumen protozoa population (8.8 × 10(5)/mL) than the buffaloes (6.1 × 10(5)/mL). The rumen protozoa population differed between the animal species, except for Dasytricha and Charonina. The buffaloes had a lower Entodinium population than the cattle (61.0 vs 84.9%, respectively) and a greater percentage of species belonging to the Diplodiniinae subfamily than the cattle (28.6 vs. 1.4%, respectively). In cattle, ground corn is a better energy source than citrus pulp for use by Entodinium and Diplodiniinae. In the buffaloes, the Entodinium are favored by urea and Diplodiniinae species by soybean meal.

Proximate analysis, expressible water(EP), water holding capacity (WHC), pH value, total acidity, free fatty acids (FFA), thiobarbituric acid values (TBA), color evaluation, and microbiological examination were determined in order to evaluate the effect of spice extracts in combination with packaging materials and treatments on the stability of ground buffalo meat product stored under frozen conditions up to six months. The samples were treated by spice extracts and packaged in two packaging materials low density polyethylene (LDPE) bags without vacuum, and laminated polyethylene/nylon bags under vacuum. The results indicated that all the samples had lost moisture during storage, and the loss was higher in samples packaged in (LDPE), also the (EP) values increased, whereas, (WHC) values decreased with time during storage for all samples. The samples indicated a reduction in the pH values and an increase in the acidity values especially for the first four months of storage and these changes were associated with an increase in the (FFA) values as a result of storage. The increment in the pH value was the lowest in the control samples and this indicated the effect of natural antioxidants to retard the formation of (FFA). The (TBA) values for the control samples were higher than those packaged under vacuum or treated by spice extracts. The storage time had a negative effect on the total bacterial counts and the coliform group for all samples. The rate of reduction was much higher in the vacuum packaged samples and the spice extracts treated samples as well especially those treated by black cumin extracts than the untreated or samples packaged without vacuum. The color measurements showed a decrease in the redness value for all samples during storage period. The rate of reduction was much higher in the control samples than the treated ones.

Full textAbstract:
Goat meat is considered healthy because it has fewer calories and fat than meat from other traditional meat species. It is also rich in branched chain fatty acids that have health advantages when consumed. We studied the effects of maternal milk and milk replacers fed to suckling kids of four breeds on the straight and branched fatty acid compositions of their muscle. In addition, the proximal and fatty acid compositions of colostrum and milk were studied. Goat colostrum had more protein and fat and less lactose than milk. Goat milk is an important source of healthy fatty acids such as C18:1 c9 and C18:2 n–6. Suckling kid meat was also an important source of C18:1c9. Dairy goat breeds had higher percentages of trans monounsaturated fatty acids (MUFAs) and most of the C18:1 isomers but lower amounts of total MUFAs than meat breeds. However, these dairy kids had meat with a lower percentage of conjugated linoleic acid (CLA) than meat kids. The meat of kids fed natural milk had higher amounts of CLA and branched chain fatty acids (BCFAs) and lower amounts of n–6 fatty acids than kids fed milk replacers. Both milk and meat are a source of linoleic, α-linolenic, docosahexaenoic, eicosapentaenoic and arachidonic fatty acids, which are essential fatty acids and healthy long-chain fatty acids.

Full textAbstract:
Water buffalo (Bubalus bubalis) conservation in Serbia is under an in situ program, but additional efforts are needed to ensure the development of this animal’s genetic resources biodiversity. This research aims to describe challenges and possible strategies for sustainable water buffalo milk production. In this study, the physicochemical characteristics of buffalo milk and buffalo dairy products (cheese, butter, and kajmak) were determined. Furthermore, amino and fatty acids composition and the related health lipid indices (atherogenic and thrombogenic) were assessed. The findings support the fact that buffalo milk is a reliable source of high-quality nutrients (dry matter: 16.10%, fat: 6.02%, protein: 4.61%). Leucine, lysine, and valine content were found to be high in buffalo milk and cheese. A substantial quantity of non-essential glutamic and aspartic amino acids was observed in milk, as well as glutamic acid and tyrosine in cheese. It was established that milk protein of buffalo cheese had a favorable proportion of essential and non-essential amino acids (61.76%/38.24%). The results revealed significant differences (p < 0.05) in fatty acid profiles among the three dairy products for saturated short-chain, n-3, and n-6 fatty acids. Conversely, no significant difference (p < 0.05) was observed in monounsaturated fatty acids content. Kajmak showed the most favorable anti-atherogenic and anti-thrombogenic properties due to lower saturated and higher polyunsaturated fatty acid content. These results confirmed that buffalo milk could be successfully used in producing high-quality traditional dairy products with added value and beneficial characteristics from the aspect of a healthy diet. Furthermore, it could actively contribute to the promotion of sustainable production of buffaloes and strengthen the agricultural production of rural areas and their heritage.

Full textAbstract:
Increasing food production and improving their quality is one of the main problems facing the agro-industrial complex of Ukraine in modern conditions. The solution of this problem is impossible only by increasing the production of livestock products, although this is the main source of their receipt. It is necessary to use additional, non-traditional types of raw materials containing full proteins, fats, vitamins, minerals and other biologically active substances necessary for the human body. One of these sources may be meat of food types of snails. It maintains a complex of replaceable and essential amino acids, vitamins, inorganic elements, carbohydrates and fats. The purpose of our work was to determine the content of fatty acids in cooked meat of the food species Helix pomatia, Helix aspersa maxima and Helix aspersa muller. This article presents the results of the content of fatty acids in meat of food snails using the method of gas chromatography. The presence and quantity of fatty acids is determined in three types of snails. In general, the meat of snails contains both saturated and unsaturated fatty acids. The composition of saturated fatty acids includes – kapron, palmithin, stearin, myristic, arachin, capryl, laurin, begen, kaprin, heptadecanova. From unsaturated fatty acids, snail meat contains omega-3, omega-6, oleinic, palmitoleic, linoleic, arachidonic, linolenic, cis-5,8,11,14,17-eicosapentaenoic, cis-11,14-eicosadenic, cis-13,16-doceta-adenoic, docosapentaenoic. As a result of our research on the content of fatty acids in cooked meat of snails, we found that the mass fraction of 11 unsaturated fatty acids – oleinic, palmitoleic, linoleic, omega-3, omega-6, arachidonic, linolenic, cis-5,8,11, 14,17-eicosapentaenoic, cis-11,14-eicosadenic, cis-13,16-doceta-adenoic, docosapentaenoic to a mass fraction of 10 saturated fatty acids is significantly different in each type of snail. Thus, the mass fraction of saturated to unsaturated fatty acids is in the meat of Helix pomatia, Helix aspersa maxima, Helix aspersa muller 1:5.73; 1:5.05 and 1:4.81 respectively. Most of all, unsaturated fatty acids are found in boiled meat of Helix pomatia snails and amount to 126.77% to the sum of fatty acids, and saturated – in the boiled meat of Helix aspersa muller snails – 24.86% to the sum of fatty acids. Useful and well-known all fatty acids ω-3 and ω-6 enriched boiled meat of Helix aspersa maxima snails – 49.06% to the sum of fatty acids, while Helix pomatia and Helix aspersa muller are 48.81 and 44.35% to the amount of fatty acids, respectively. It should be noted that the total content of fatty acids in the meat of snails varies in the following limits: Helix pomatia snails 148.89, Helix aspersa maxima 149.11, and Helix aspersa muller 144.4. Thus it can be argued that in the boiled meat of the three types of snails we studied, which is Helix pomatia, Helix aspersa maxima and Helix aspersa muller can be used as a valuable source of saturated and unsaturated fatty acids.

Full textAbstract:
Three experiments, two with pigs and one with Atlantic salmon, (Salmo salar) were carried out to investigate the effects of dietary supplementation with α-tocopheryl acetate (ATA) on quality of pig and salmon tissues. In Experiment 1, 32 pigs were individually fed either of two dietary fat sources: 0.5:0.5 w/w coconut oil/lard (59 g/kg finisher diet) or rapeseed oil (100 g/kg finisher diet) (as contained in full-fat rapeseed {FFR}), with or without supplementary ATA at 200 mg/kg diet. In Experiment 2, 24 pigs were individually fed either a diet which contained mixtures of vegetable oil (59 g/kg diet) (having a high level of palm oil) or rapeseed oil diet as in Experiment 1. The rapeseed oil diets were supplemented with 0, 200 and 500 mg ATA/kg diet. In Experiment 3, a commercial diet with high lipid content (290 g/kg diet) and 250 mg ATA/kg diet was supplemented with 0, 400 and 700 mg ATA/kg diet. Diets were fed to 54 salmon. Tissue samples were stored at 4°C and/or -20°C for different periods. Spectral data on tissue samples were collected with an NIRSystems 6500 scanning monochromator. Salmon and pig tissues, and pig muscle subcellular fractions (microsomal and mitochondrial) were analysed for fatty acid composition, α-tocopherol (AT) content and oxidative stability (by thiobarbituric acid test). In both pigs and salmon, muscle drip loss was measured, and the colour score and carotenoid content of salmon fillets were determined. Data presented in this study indicate that pig tissues respond positively to increased dietary supply of unsaturated fatty acids (UFA). Pig tissue UFA and n-3 fatty acid contents were increased, and n-6/n-3 fatty acid ratio was decreased by feeding diets containing FFR. There was only a slight influence of dietary fatty acids on fatty acid composition of the subcellular membranes. AT concentration was higher in the mitochondrial fraction than the microsomal fraction. The mitochondrial fraction lipids had a higher content of UFA than those of the mcirosomal fraction. Supplemental dietary ATA increased the AT content of both pig and salmon tissues.

Full textAbstract:
Lipid oxidation is the main factor which limits the shelf-life of meat when held under frozen storage. Research undertaken used pork phospholipid liposomes as a model for studying lipid oxidation in meat. Oxidation was followed by monitoring the decrease in the phospholipid unsaturated fatty acyl chains. It was found that the greater the level of unsaturation of the phospholipid fatty acyl chain the greater was their susceptibility to peroxidation. However, the results were not consistent and several reasons for the variation in rate are provided. At ambient temperatures copper (II) was found to be pro-oxidant in the peroxidation of liposomes. At temperatures below 0°C the prooxidant activity of copper (II) was significantly reduced. However copper again became highly pro-oxidant if sodium chloride was present. It is suggested that salt controls the copper ion concentration at sub-zero temperatures as the pro-oxidant activity of copper (II) is reduced on increasing the copper (II) concentration from 0.9 to 90 ppm. Other experiments found sodium nitrite and pholyphosphate to act as antioxidant and that liposome structure was an important factor in the rate of peroxidation. Four storage trials on pork burgers were undertaken to determine whether salt was also pro-oxidant in the stability of pork when held under frozen storage. The oxidative deterioration of the meat was followed by the following methods of analysis:- 1. The decrease in the unsaturated acyl chains of both total lipid and phospholipid. 2. The change in the colour parameters of the meat using reflectance spectroscopy. 3. The analysis of neutral lipid oxidation products by HPLC. 4. The organoleptic qualities of the pork using a trained panel of food assessors. The results from these storage trails showed that the deterioration of pork was minimised by storing the burgers at lower temperatures within the range 0 to -30°C. Salt was found to accelerate the oxidative deterioration of both uncooked and cooked pork when stored at -20°C. Nitrite was found to exhibit some antioxidant behaviour and reduce the pro-oxidant effect of salt.

Full textAbstract:
Consumer evaluation, proximate data, Warner-Bratzler shear force (WBSF), fatty acid (FA) composition and volatile compounds were analyzed from the Longissimus thoracis (LT), Tricep brachii (TB) and Gluteus medius (GM) muscles finished on conventional feedlot (FL) and forages, including a perennial legume, birdsfoot trefoil (BFT; Lotus corniculatus), and a grass, meadow brome (Bromus riparius Rehmann, Grass). Representative retail forage (USDA Certified Organic Grass-fed, COGF) and conventional beef (USDA Top Choice, TC) were investigated (n = 6) for LT. Additionally, the effects of diet on Gluteus medius (GM) and Tricep brachii (TB) muscles were explored. Forage-finished beef scored lower (P < 0.05) in most of the affected sensory attributes except BFT which was similar to grain-finished beef. In forage-finished beef GM was more liked and in FL, TB was similar to GM except juiciness where it scored greater. The fat percent was found to be greatest (P < 0.05) in TC followed by BFT and FL. Nutritionally beneficial ratios of FAs were observed in forage-finished diet. Fatty acid concentrations were majorly affected (P ≤ 0.046) by diet. Few long-chain PUFAs were affected (P ≤ 0.015) by muscle type. No FA was a effected (P > 0.05) by the interaction of muscle and diet. 3-hydroxy-2-butanone, known to evoke a buttery sensation was affected (P = 0.011) by diet with greater (P < 0.05) concentration in GM across all diets. Strecker degradation products were affected (P ≤ 0.014) by muscle type being prominent in GM. Meanwhile, 2-ethyl-3,5-dimethyl-pyrazine was greatest (P < 0.05) in BFT. All pyrazine compounds were (P < 0.05) greater in GM. These results indicate that when consumer evaluated beef of finishing diets, FL beef was rated highly. Additionally, not all forages produce similar beef. There were similar ratings for BFT for all attributes except flavor having lower values compared with FL. The chemical composition of BFT beef was found to be intermediary and similar to both FL and Grass beef in many cases. Diet was found to interact with muscle for sensory and chemical measures. The GM and TB of FL did not differ (P < 0.05), while within forage treatments sensory response and chemical composition varied. These results indicate the meat quality of secondary beef muscles is more greatly impacted by forage diets.

Ruminant meats are characterized by being rich in saturated fatty acids (SFA), particularly, and low in polyunsaturated fatty acids (PUFA), which is regarded as disadvantageous for humans. However, ruminant meats are also the dietary source of some bioactive health benefit fatty acids, including conjugated linoleic acid isomers (CLA) and long chain polyunsaturated fatty acids from the n-3 series (n-3 LC-PUFA). In the present thesis we have explored three nutritional strategies to improve the fatty acid (FA) profile of lamb meat, in order to maximize CLA and n-3 LC-PUFA content. Two experiments were conducted to evaluate the effects on lipid metabolism and fatty composition of meat from lambs intensively fattened of the i) dietary inclusion of Cistus ladanifer L. (C. ladanifer); ii) dietary supplementation with vegetable oils and iii) replacement of cereal grains by dehydrated citrus pulp (DCP) in diets. A global evaluation of the effects of the dietary treatments on production, meat quality and meat lipid composition, was achieved by recording the productive performance of lambs, carcasses composition, and determining analytically the fatty acid composition, oxidative stability and organoleptic quality of meat. Moreover, the expression of genes encoding Δ5-, Δ6- and Δ9-desaturases (FADS1, FADS2 and SCD) in longissimus muscle was also assessed. The first experiment, involved 54 Merino Branco lambs, and evaluated the effects of the dietary inclusion of C. ladanifer (rockrose) (Cistus) and of the lipid supplementation with a blend of linseed and soybean oil (2:1 vol/vol). Nine diets were formulated resulting from the combination between 3 levels of C. ladanifer inclusion (50, 100 and 200g/kg of dry matter (DM)) and 3 levels of oil supplementation ((0, 40 e 80g/kg DM)). On second experiment, 32 Merino Branco lambs were fed using diets containing 60g/kg DM of soybean oil and 50% of dehydrated lucerne, and there were evaluated the effects of C. ladanifer inclusion (0 vs 150g/kg) DM) and the replacement of cereal grains by DCP in the diets. On the first experiment, the diets did not affect animal´s growth. Lipid suplementation reduced DM intake, muscle proportion in the carcass and increased kidney knobb channel fat. Meat chemical and physical parameters were not influenced by the diets. The level of 100g/kg of C. ladanifer inclusion improved meat oxidative stability during 7 days of storage. The perception of off-flavours was higher and meat overall acceptability by the sensory panel was reduced with suplementation 8% oil blend. The increasing inclusion of C. ladanifer and oil in the diet act sinergetically on the 10t-18:1 in meat. C. ladanifer increased total amount and proportion of trans monoinsaturated FA (trans MUFA) and reduced the proportions of eicosapentaenoic (EPA) and docosapentaenoic (DPA) acids. The dietary suplementation with vegetable oil blend was a good strategy to improve nutritional value of meat, enhancing total amount of linolenic acid (18:3 n-3) and of n-3 PUFA, and reducing the proportion of SFA, which it was followed by an increment of the proportion of PUFA on lipid profile of intramuscular fat (IMF). The expression of the SCD mRNA increased with C. ladanifer but it was not correlated with the concentration of the Δ9-desaturase FA products. On the second experiment, DM intake increased with C. ladanifer, althought growth was not influenced by diets. Carcass composition was not affected by the dietary treatments, but an interaction between C. ladanifer and DCP was observed for dressing percentage. Dietary factors did not influence muscular pH, cooking losses, meat color and oxidative stability during storage. However, meat shear force increased with the adition of C. ladanifer to diets. Meat tenderness and juiciness were both reduced by C. ladanifer and DCP, but only C. ladanifer reduced meat overall acceptability assessed by the sensory panel. The inclusion of C. ladanifer to 1:1 forage to concentrate ratio diets enriched with soybean oil, reduced the occurrence of trans-10 shift, but did not increase 11t-18:1 and 9c,11t-18:2 concentrations on meat lipids. Trans fatty acids (TFA) were reduced by C. ladanifer inclusion in diets. Dehydrated citrus pulp improved meat nutritional value by increasing 18:3 n-3.
RESUMO - Enriquecimento em ácidos gordos bioactivos da carne de borrego de sistema intensivo através da modulação nutricional do metabolismo lipídico - A carne de ruminantes caracteriza-se por ser particularmente rica em ácidos gordos saturados (AGS) e pobre em ácidos gordos poliinsaturados (AGPI), o que é considerado como negativo para a dieta humana. Contudo, é também uma importante fonte de alguns ácidos gordos bioactivos benéficos para a saúde, como os isómeros conjugados do ácido linoleico (CLA) e ácidos gordos poliinsaturados de cadeia longa da família n-3 (n-3 CL-AGPI). Na presente tese explorámos três estratégias nutricionais de modo a melhorar o perfil lipídico da carne de borrego através do aumento do seu conteúdo em CLA e em n-3 n-3 CL-AGPI. Foram realizadas duas experiências nas quais os efeitos i) da inclusão de Cistus ladanifer L. (esteva); ii) da suplementação lipídica com óleos vegetais e iii) da substituição dos grãos de cereais por polpa de citrínos desidratada (PCD) no metabolismo lipídico e na composição em ácidos gordos da carne de borrego de sistema intensivo de engorda foram avaliados. A avaliação integrada dos efeitos dos tratamentos no desempenho produtivo, foi efectuada registando-se a ingestão de matéria seca (MS), ganho médio diário e composição das carcaças dos borregos, assim como a qualidade física e sensorial da carne e a sua composição em ácidos gordos e níveis de expressão dos genes que codificam para as Δ5, Δ6 e Δ9-desaturases (FADS1, FADS2 e SCD mRNAs). No primeiro ensaio, que envolveu 54 borregos Merino Branco avaliámos a inclusão, na dieta, de Cistus ladanifer (esteva), e da suplementação lipídica constituída por uma mistura de óleo de linho e de soja (2:1 vol/vol). Para tal foram formuladas 9 dietas que resultaram da combinação entre 3 níveis de inclusão de C. ladanifer (50, 100 e 200g/kg de matéria seca (MS)) e 3 níveis de suplementação lipídica (0, 40 e 80g/kg de MS). No segundo ensaio, utilizaram-se 32 borregos alimentados com dietas contendo 50% de luzerna desidratada e 60g/kg MS de óleo de soja, e avaliaram-se os efeitos da inclusão de C. ladanifer (0 vs 150g/kg) de MS) e da substituição dos grãos de cereais por polpa de citrínos desidratada (PCD) nas dietas. No primeiro ensaio, os tratamentos não afectaram o crescimento dos animais. O óleo reduziu a ingestão de MS, a proporção de músculo da carcaça e aumentou a quantidade de gordura pélvica e renal. As caraterísticas físicas e químicas da carne não foram afectadas pelas dietas. O nível de 100g/kg de esteva melhorou a estabilidade oxidativa da carne durante o armazenamento de 7 dias. A percepção de off-flavours foi superior e a aceitação global por parte do painel de provadores foi inferior para a suplementação com 8% de óleo. A inclusão de C. ladanifer potenciou o aumento de 10t-18:1 na carne induzido pelo óleo. Com a inclusão de C. ladanifer nas dietas aumentou a quantidade total e proporção de ácidos gordos monoinsaturados trans (TransAGMI) e diminuiram as proporções dos ácidos eicosapentaenoico (EPA) e docosapentaenoico (DPA). A suplementação das dietas com a mistura de óleos vegetais foi uma boa estratégia para melhorar o valor nutricional da carne, permitindo um aumento da quantidade total de ácido linolénico (18:3 n-3) e n-3 AGPI, e a redução da proporção de AGS acompanhada de um aumento da proporção de AGPI no perfil lipídico da gordura intramuscular. A expressão do mRNA do gene SCD aumentou com a inclusão de C. ladanifer nas dietas. No segundo ensaio, a ingestão de MS aumentou com a inclusão de C. ladanifer, embora o crescimento não tenha sido influenciado pelas dietas. A composição da carcaça não foi afectada pelos tratamentos, mas verificou-se uma interacção entre a inclusão de esteva e a de PCD que afectou o rendimento da carcaça. Os factores em estudo não influenciaram o pH muscular, as perdas por cozedura, a cor da carne e a sua estabilidade oxidativa. No entanto, ocorreu um aumento da força de corte da carne com a adição de C. ladanifer às dietas. A tenrura e a suculência da carne sofreram uma diminuição com a inclusão de C. ladanifer e de PCD nas dietas, no entanto a aceitação global da carne pelo painel de provadores apenas foi diminuída com C. ladanifer. A inclusão de C. ladanifer a dietas com uma relação de forragem: concentrado de 1:1 e enriquecidas com óleo de soja, reduziu a ocorrência do trans-10 shift, embora não tenha aumentado os teores de 11t-18:1 e de 9c,11t-18:2 na fracção lipídica da carne. O total de ácidos gordos trans (AGT) na carne foi reduzido pela inclusão de esteva nas dietas. A PCD melhorou o valor nutricional da gordura da carne de borrego, aumentando a concentração em 18:3 n-3.

Full textAbstract:
Apart from breast milk, no single food contains all the essential nutrients the body needs to be healthy and function efficiently. The nutritional value of a person’s diet depends on the overall balance of foods eaten over a period of time, as well as on the needs of the individual. Over the last 60 years, there has been increasing agreement about the balance of nutrients and foods that make up a ‘good’ diet. This consists primarily of wholegrains (i.e. cereal grains, or foods made from them, containing bran, germ, and endosperm, e.g. wholemeal breads, oatmeal, and dark rye); vegetables and fruit, including nuts and pulses; moderate amounts of fish and low-fat dairy foods; and limited amounts of meat. The consumption of saturated fat should be low, with saturated fat being replaced by mono- and polyunsaturated vegetable fats and fish oils. Trans-fatty acids should be minimized, and added sugar should provide no more than 10% of energy intake. However, as omnivores, humans can survive on a wide range of different foods, and many people worldwide eat diets that fall far short of this ideal.

Full textAbstract:
A discussion about the nutritional composition of game meat, with specific focus on wild species harvested in Central and Mediterranean European countries has been conducted. Given the wide range of species, and the climate and vegetation differences among the harvesting areas, game meat shows heterogeneous characteristics and chemical composition, the latter being also affected by sex, age, body condition, physiological and sexual status, and hunting period. However, there are similarities which make it clearly distinguishable from livestock meat. When considering the most consumed species (red and fallow deer, wild boar, hare and wild rabbit), their meat has low fat content (<3 g/100 g for large and <4 g/100 g for small wild game species), high protein content (20–26 g/100 g) and low energy content (90–113 kcal/100 g). Wild game meat has a healthier fatty-acids profile compared to other meats, showing a higher proportion of PUFA, especially n-3, and consequently more favorable PUFA/SAF ratio. Wild ruminants’ meat shows a favorable n-6/n-3 ratio (lower or close to 4). It has a high content of K, followed by P and micro-minerals such as Zn and Fe, together with B-group vitamins and vitamin E. Game meat from wild species harvested in Europe can diversify the market being an alternative to others red meats owing to its nutritional quality and organoleptic characteristics.

Full textAbstract:
One of the key areas in animal husbandry is to improve the quality (nutritional value) of dairy and meat products by enriching them with Conjugated Linoleic Acids (CLAs) like (cis-9, trans-11)- and (trans-10, cis-12)-octadecadienicacids; the former (rumenic acid) predominates all the CLAs. Though Vaccenic Acid (VA) is the immediate precursor of rumenic acid, dietary unsaturated fatty acids like Oleic Acid (OA), Linoleic Acid (LA) and a-Linolenic Acid (ALA) are the distant precursors of CLAs; and that CLA and VA are formed as intermediates during the biohydrogenation of the dietary OA, LA and ALA into fully saturated stearic acid. The mutual inter-relationship of rumen microbiota encompassing bacteria, protozoa and fungi facilitates the biohydrogenation process. Thus, this chapter critically evaluates the knowledge accumulated during the past four decades on the precursor of CLAs, micro-organisms involved in the production of CLA, the mechanism of biohydrogenation, and chemical synthesis of CLA, coupled with the rationale for biohydrogenation and factors affecting the production of CLA.

This chapter considers specific nutritional factors of indigenous peoples in Russia's Arctic zone. The authors have identified the prerequisites for the optimization of the diets of indigenous peoples in the light of existing environmental and medical-biological problems. A low level of self-sufficiency of local population with basic food products (meat, dairy, and egg products) was identified. The chapter provides a detailed analysis of the chemical composition of chia seeds as a promising ingredient of the northern diet, in particular the biological value of a product based on protein, lipid, carbohydrate, mineral, and vitamin components. The authors proposed considering chia seeds as a part of the composition of various food products for functional purposes. Potentially, the inclusion of scientifically based food recipes in the diets let providing the indigenous people with balanced food products.

Full textAbstract:
Scientific evidence and nutritional guidelines recommend a reduction in total fat intake, particularly of saturated fatty acids, which are associated with an increased risk of obesity, hypercholesterolemia, and cancer. Nutritionists recommend a higher intake of polyunsaturated fatty acids (PUFA), especially n-3 PUFA at the expense of n-6 PUFA. Besides the beneficial effects of n-3 fatty acids on human health, the conjugated linoleic acid (CLA) isomers have attracted increased attention as a result of their health promoting biological properties. As milk and meat are the main sources of CLA for human consumption, increasing such important nutrient in animal products is strongly recommended. Fat supplementation is one of the methods of increasing PUFA content in ruminant products, and it has been shown that PUFA can be increased in milk by supplementation with vegetable oils and oil seeds. Vegetable oils as equivalent to oilseeds show similar effects on CLA content in ruminant products.

Full textAbstract:
The urgency of the work is the need to establish criteria for assessing the safety and quality of poultry meat at facilities for its production and storage, due to the development of new express and improved common methods of controlling the safety and quality of poultry meat for risks (biological, chemical, physical) their life cycle. Studies have assessed the safety and quality of poultry carcasses using new and improved methods for determining the acid and peroxide levels of fat compared to conventional methods for determining the degree of freshness of poultry meat. Organoleptic evaluation of fresh poultry meat was established – for storage in a refrigerated chamber at a temperature of 0−4 °С for 5 days; doubtful degree of freshness – birds for storage in a refrigerator at a temperature of 0−4 °C for 6–7 days; stale – for storage in a refrigerator at a temperature of 0−4 °C for more than 7 days on the appearance of the carcass, color, odor on the surface of the carcass and near the bones, the state of the thoracic cavity, subcutaneous and internal adipose tissue, muscle consistency, broth for cooking samples. There is a high probability of acid number of poultry fat of moderate freshness – 1.76±0.12 mg of NaOH (p≤0.001) and stale fat – 2.83±0.07 mg of NaOH (p≤0.001) compared to the acid number of fresh fat poultry (0.72±0.04 mg NaOH), as well as indicators of volatile fatty acids (VFA) in poultry meat of moderate degree of freshness – 6.62±0.43 mg KOH (p≤0.001) and stale fat – 11.05±0.37 mg KOH (p≤0.001) compared to the content of VFA of fresh poultry meat (2.61±0.24 mg KOH). Studies have established a high reliability of determining the indicators of volatile fatty acids in poultry meat – in 98.2–99.7 % and the results of studies on the indicators of the microscopic method for determining the number of bacteria in poultry meat – in 98.5–99.8 % compared to the acid number as determined by the developed method. The reliability of the indicators for determining the acid number of poultry fat was according to the developed method was 99.9 %. Therefore, the developed method for determining the acid number of poultry fat can be used to determine the quality of poultry meat, because the quality of meat depends on the quality of fat: the acid number of fresh poultry fat – up to 1.0 mg of NaOH; questionable degree of freshness – from 1.1 to 2.5 mg of NaOH; stale – more than 2.5 mg of NaOH. There is a high probability of peroxide content of poultry fat of the appropriate degree of freshness – 0.029 ± 0.002% J (p≤0.001) and stale fat – 0.063±0.003 % J (p≤0.001) compared to the peroxide value of fresh poultry fat (0.010±0.0007 % J), as well as indicators of volatile fatty acids (LFA) in poultry meat of moderate degree of freshness – 6.40±0.48 mg KOH (p≤0.001) and stale fat – 10.43±0.23 mg KOH (p≤0,001) compared to the VFA content of fresh poultry meat (2.58±0.23 mg KOH). The results showed that more reliable data compared to the results of studies for the determination of volatile fatty acids in poultry meat – 98.5–99.7 % and the results of studies on the indicators of the microscopic method for determining the number of bacteria in poultry meat – 99.0–99.6 % were obtained using the developed improved method. The reliability of the indicators for determining the peroxide value of poultry fat according to the developed improved method was 99.9 %. Therefore, the developed improved method for determining the peroxide value of poultry fat can be used to determine the quality of poultry meat, because the quality of meat depends on the quality of fat: peroxide value of fresh poultry fat – up to 0.010 % iodine of questionable degree of freshness – from 0.010 to 0.040 % iodine; stale – more than 0.040% iodine. The developed methods for determining the safety and quality of poultry carcass fat can be used by state veterinary inspectors as simple test methods to carry out appropriate state risk-based control of poultry meat production and storage facilities.

The results of the study at hand may have implications for treatment of grease, lipid fractions, free fatty acids (FFA) and salts of FFA extracted from wastes of food industry, bio-refineries or sewage sludge as well as contaminated lipid containing forage. The goal of the study is, to prevent such contaminated wastes from entering the food chain. The following ways of treatment are proposed. Thermal conversion of waste fats from rendering plants or lipids in the presence of aluminosilicates of the zeolite family produce hydrocarbons with net calorific values in the range of 40–42 MJ/kg. NMR studies show aliphatic hydrocarbons as main product at T = 400°C. The spectrum of products is shifted to alkyl benzenes at T = 550°C. In case of sodium carbonate conversion is achieved in the presence of 5% water at T = 430 ± 20°C yielding mainly a liquid bio-crude with a low acid index, a mixture of non-condensable gases and minor amounts of coke. Rectification of bio-crude from animal fat produces 65.8% of hydrocarbon based bio-diesel and 13.3% of gasoline type hydrocarbons. Distillation curve for bio-diesel is in accordance with DIN EN 490. However, the gasoline fraction lacks low boiling hydrocarbons indicating the necessity for technical improvements of condensers. Sodium carbonate is found to be effective as well as being relatively inexpensive compared to zeolite catalysts. Finally, successful conversion of meat and bone meal to biochar is proved by solid-state 13C-NMR.
