Abstract:
AbstractIn this study, maize landraces, previously collected from different regions of Turkey through a national maize breeding project, were screened for kernel oil content and oil quality. After a seed reproduction in 2017, the screening trial was conducted in 2018, using an Augmented Experimental Design with 192 local maize populations along with seven check hybrids. Data were collected on oil, oleic acid, linoleic acid, monounsaturated (MUFA), polyunsaturated and saturated fatty acids, total carotenoid and total tocopherol contents. The results showed that there was a considerable amount of genetic variation among the Turkish maize landraces for almost all the traits investigated in this study. Some of the evaluated landraces are available that could be considered as high oil variety or special genotypes in terms of certain oil quality traits. Landraces had significantly higher values than checks for oil content, oleic acid, MUFA and tocopherol contents. Genetic analyses suggest that the kernel quality traits could be successfully manipulated using the investigated plant material. Heritability values were found high for all the traits of interest, except for saturated fatty acid and total carotenoid content. The promising landraces detected in this study could be exploited in future breeding programmes upon further evaluations at the population level.

Abstract:
In this study, different oil extraction processes, such as extrusion pretreatment, ultrasound-ethanol assisted demulsification and traditional hexane extraction of oil, were employed to extract oil from soybean in order to compare their different effects on oil quality, fatty acid distribution and VE content of oil. The result shows that the quality of oil from extrusion pretreatment aqueous enzyme extraction (EAEP) of oil and ultrasound-ethanol assisted demulsification aqueous enzyme extraction of oil were same. The raw oil quality from the above two processes was better than the hexane extraction of oil. The fatty acid contents of oil were similar in different oil extraction processes. The VE content of oil from ultrasound-ethanol assisted demulsification process was decreased, while the extrusion pretreatment aqueous enzyme extraction of oil had no influence on VE concentration.

Abstract:
Ecological conditions of the growing areas, growing practices as well as harvest and postharvest processing influence the yield and quality of chamomile. The aim of this research was to determine the influence of chamomile separation methods, as postharvest treatments, on the essential oil quality and content, with a view to improve current primary processing of this valuable medicinal plant. In order to explain the structure of laboratory data that would give deeper assessment of similarities among various samples of chamomile essential oil, PCA was employed. Tested results showed that separation of chamomile plant material, as postharvest and pre-drying treatment, had significant influence on the number of identified compounds in the chamomile essential oil. The highest content of individual essential oil compounds had chamomile flowers with short stems, especially a-bisabolol, chamazulene, Z-spiroether and E-b-famesene. In the essential oil obtained from chamomile flowers with long stems, content of a-bisabolol and chamazulene were significantly lower, while E-b-famesene and Z-spiroether contents were significantly higher. Furthermore, in the essential oil obtained from chamomile plant material without separation, the lowest content of abisabolol and Z-spiroether, and the highest content of E-b-farnesene were recorded. The correlation analysis was performed to investigate the likeness in the amounts of the active compounds of essential oil from differently processed chamomile samples. All these results indicate the importance of precise and controlled postharvest treatments, since it clearly affects the essential oil quality and content in the primary processing of this valuable medicinal plant.

Abstract:
Abstract The quality of edible oils is now receiving increasing consideration from consumers and processors. The present study was conducted to investigate the effects of environments on oil content and fatty acid composition in peanut. The correlation between oil content and oil quality parameters was also studied. Thirteen peanut (Arachis hypogaea L.) genotypes were grown in 12 environments for the study. Soils at experiment locations differed significantly for pH, EC, and N, P, Zn, Mn, and Fe contents. Significant genotype, environment, and genotype x environment interaction effects were observed for oil content, individual fatty acid contents, and derived oil quality parameters. The original range of 34-54% of oil content based on one season/location evaluation in these lines was not repeatable, and ranged from 45-50% in multilocation evaluation. Oil content was positively correlated with soil pH and Fe content. The correlation of oleic and linoleic acid content with soil pH and Fe content was positive in the former and negative in the latter. The oil content was positively correlated with O/L ratio. Oliec and linoleic acid contents were negatively correlated. Selection for reduced linoleic acid level in genotypes would also reduce levels of total long chain saturated fatty (TLCSF) acids. Of the thirteen genotypes tested, ICG 5856, ICG 5369, and ICGV 87124 could be used in breeding for improved oil quality.

Abstract:
An improvement in the quality of maize grain by increasing the level of components responsible for its biological value is possibleby using genetic means. However, a change in the genotype, together with improving the nutrient properties of the grain, also has someadverse consequences connected with a fall in yield and in resistance to diseases.Field experiments were conducted during three years (2003, 2004and 2005) to evaluate environmental effects on grain yield andquality responses of maize hybrids. Twenty one hybrids of various maturity groups (FAO 150-400) were planted to achieve an optimum(60-70 000 plants per hectare) plant populations and grown under the medium-N (80 kg N ha-1) fertilization. Environmental conditionssignificantly affected maize hybrid responses for grain yield, starch, oil and protein contents, and consequently, starch, oil and proteinyields per hectare. Hybrids of flint type, which have a short vegetation period, had high protein and oil content but the yield averageswere low due to the slower rate of starch incorporation. Hybrids of the dent type have a longer growing season and more intensecarbohydrate accumulation, but low protein and oil contents. In wet years there was a higher rate of starch accumulation, while dryyears are favorable for protein and oil accumulation. Positive correlation existed between starch content and grain yield and 1000-weight as well as between oil content and volumetric weight among tested hybrids. Negatively correlation existed between grain oil andstarch content as well as between oil content and grain yield and 1000-weight. Thus, end-users that require high quality maize may needto provide incentives to growers to off set the negative correlation of grain yield with oil and protein content.

Abstract:
Macauba is an oleaginous palm species from Latin America. It is a rich source of vegetable oil with diverse benefits. However, there are several gaps in assuring post-harvest oil quality of the mesocarp. Thus, ripe fruits were stored at room temperature for 60 days before oil extraction to evaluate fruit and mesocarp oil quality attributes. Physical (decay incidence, water activity), biochemical (specific activity of lipase), physicochemical (acidity and peroxide indices, molar absorptivity at K232 and K270, oxidative stability, total carotene content and mesocarp colour) analyses were carried out. Results show that nonlinear sigmoid response was obtained for most of the parameters evaluated. Decaying reactions related to microorganism’s growth, free fatty acid release and oxidation took place along storage. However, the overall oil quality was in the acceptable limits up to 20 days of storage. It is much further than palm oil, the main source of oil in the world.

Abstract:
In this review the quality properties of linseed oil for food uses are discussed as well as factors affecting this quality. Linseed oil has a favourable fatty acid composition with a high linolenic acid content. Linseed oil contains nearly 60% á-linolenic acid, compared with 25% for plant oils generally. The content of linolenic acid and omega-3 fatty acids is reported to be high in linseed grown in northern latitudes. The composition of fatty acids, especially unsaturated fatty acids, reported in different studies varies considerably for linseed oil. This variation depends mainly on differences in the examined varieties and industrial processing treatments. The fatty acid composition leads also to some problems, rancidity probably being the most challenging. Some information has been published concerning oxidation and taste, whereas only a few studies have focused on colour or microbiological quality. Rancidity negatively affects the taste and odour of the oil. There are available a few studies on effects of storage on composition of linseed oil. In general, storage and heat promote auto-oxidation of fats, as well as decrease the amounts of tocopherols and vitamin E in linseed oil. Several methods are available to promote the quality of the oil, including agronomic methods and methods of breeding as well as chemical, biotechnological and microbiological methods. Time of harvesting and weather conditions affect the quality and yield of the oil.;

Abstract:
Pumpkin seeds oil are rich in biologically active substances such as a source of tocopherols, carotenoids, especially β-carotene, lutein and other compounds. Also four fatty acids – palmitic, stearic, oleic and linoleic, dominated in the oil of pumpkin seeds oil. The study mainly aimed to evaluate the fatty acid contents and antioxidant parameters of seed oils isolated from different pumpkin cultivars. Investigations of seeds oil from Cucurbita pepo L. ‘Miranda’, ‘Golosemianaja’, and ‘Herakles’ pumpkin cultivars grown in Lithuania revealed that crude fat contents ranged from 44.4% to 47.3%, although ‘Miranda’ cultivar seeds consistently and significantly had the lowest content. The seed oils contained appreciable amounts of unsaturated fatty acids (approximately 83%), of which polyunsaturated fatty acids, particularly palmitic, stearic, oleic and linoleic acids, were dominant with values ranging from 64.29% to 66.71% of the total amount of fatty acids. The seeds oil were a particularly rich source of linoleic acid (66%), among which ‘Miranda’ cultivar seeds had the significantly highest content. Our investigation identified that pumpkin seeds oil as a good source of phenolic compounds, particularly cvs. ‘Golosemianaja’ and ‘Miranda’ oil. Methanolic seed oil extracts were characterized by statistically significant differences in their antioxidant activity, with the highest antioxidant activity found in cultivar ‘Miranda’, followed by ‘Golosemianaja’. The antioxidant activity level increased proportionally with the total phenolic content, thus establishing a linear relationship between DPPH-radical scavenging activity and total phenolic content.

Abstract:
Previous research has shown that microsomal DGAT activity from cultures of Brassica napus was stimulated by human acylation stimulating protein (ASP) and bovine serum albumin (BSA). Genetic constructs were engineered to facilitate the expression of ASP or BSA in developing seeds to test the stimulatory effect of these proteins at the site of TAG formation. As well, genetic constructs were designed to produce a truncation of the BSA polypeptide in an attempt to localize the portion fo the macromolecule responsible for stimulation of DGAT activity. An oleosin promoter was used for seed specific expression and to express the polypeptides at a precisely cooridnated time when oil was accumulating in the developing seeds. Lipid analysis coordinated time when oil was accumlating in the developing seeds. Lipid analysis was performed on the seeds of transgenic plants designed to cytosolically express these mammalian proteins and the seeds of control plants. The first generation data revealed that the total lipid within the mature seeds of ASP and BSA plants was not significantly different from the total lipid of negative control plants using both gravimetric and low resolution-nuclear magnetic resonance methods of analysis. The seeds from ASP 8 and ASP 10 plants, however, did produce significantly more lipid on a per seed basis as compared to negative control plants. The levels of the fatty acid composition for total acyl lipids were measured in these first generation transgenic plants. ASP 3 had significantly lower levels of linoleic acid, ASP 14 had significantly lower levels of a-linolenic acid and BSA 11 had significantly higher levels of both of these fatty acids in comparison to negative control plants.

The macaw palm [Acrocomia aculeata (Jacq.) Lodd. Martius ex] presents itself as a promising source of vegetable oils, especially as feedstock for biodiesel production. This is due to the high oil content in the mesocarp and almond fruit, the ability to take full utilization of these fruits, besides the great adaptability of this species to climatic conditions. However, missing information for conservation of oil quality after harvesting and storage of fruits, generating the need to develop studies that extend the shelf-life while maintaining the quality of the extracted oil. The objectives of this study were to evaluate the quality and content of mesocarp and almond oil in macaw palm fruits undergoing physical treatments of gamma radiation and drying during storage at room temperature. We carried two experiments: the first one, 120 experimental units were treated with doses of 0, 0.5, 1.0, 3.0 5.0 and 10.0 kGy of gamma radiation and stored for 0, 15, 30 , 45 and 60 days at room temperature. The interaction between dose and storage time was significant. Best visual quality was observed in fruits irradiated with higher doses, in the first days of storage. The free fatty acid from irradiated fruits were lower than the control treatment and doses of 10.0 kGy showed the highest reduction of this index. Gamma radiation reduced the oil accumulation and oxidative stability in the mesocarp. The water content in the mesocarp oil increased with increasing dose and time of storage. The oleic acid and lauric acid are present in higher quantities in the mesocarp and almond oil, respectively. Among the major fatty acids present in the mesocarp and almond oil, oleic acid is the fatty acid that presents major changes during storage. In the second experiment, 100 units experimental of macaw palm fruits were submitted to different combinations of temperature and drying time: 1) without drying the fruits (SS) 2) dried in a oven at 45°C for 4 days (45°C / 4d), 3) drying in an oven at 65°C for 4 days (65°C/4d), 4) drying in an oven at 45°C for 8 days (45°C/8d); 5) dried at 65°C for 8 days (65°C/8d). After this treatment the fruits were conducted to storage at room temperature for 0, 15, 30, 60 and 120 days. There are influence of the drying process and storage time in the evaluated characteristics. Drying at 65°C for 8 days was effective for maintaining stable the free fatty acid index of the mesocarp oil during storage. Drying restricted the accumulation of oil in the mesocarp and almond fruit. The oxidative stability was reduced by drying treatment. Higher concentrations of oleic and lauric fatty acids were found in mesocarp and kernel oils, respectively. The variations observed in the almond oil were with lower intensity than those obtained in the mesocarp oil, and oleic fatty acid is more susceptible to variation during storage. Physical treatments of gamma radiation and drying helped in preserving the fruit. Both had minor progressions in the free fatty index compared to the control treatment during storage, but the drying treatment was more effective in controlling the free fatty acid in the oil of the fruit. The oil accumulation and oxidative stability were reduced in both treatments. The drying treatment provides smaller variations in fatty acid profile for the mesocarp and almond oil.
A macaúba [Acrocomia aculeata (Jacq.) Lodd. ex Martius] apresenta-se como fonte promissora de óleos vegetais, especialmente como matéria-prima para produção de biodiesel. Isso se deve ao elevado teor de óleo no mesocarpo e na amêndoa dos frutos, à possibilidade de completo aproveitamento desses frutos, além da grande adaptabilidade dessa espécie às condições climáticas brasileiras. Entretanto, faltam informações para conservação da qualidade do óleo após a colheita e armazenamento dos frutos, gerando a necessidade de desenvolver estudos que prolonguem a vida pós-colheita, mantendo a qualidade do óleo extraído. Os objetivos desse trabalho foram avaliar a qualidade e teor de óleo do mesocarpo e da amêndoa de frutos de macaúba submetidos a tratamentos físicos de radiação gama e secagem, ao longo do armazenamento, à temperatura ambiente. Realizou-se dois experimentos: no primeiro experimento, 120 unidades experimentais, compostas por 24 frutos de macaúba, foram tratadas com as doses de 0; 0,5; 1,0; 3,0 5,0 e 10,0 kGy de radiação gama e armazenadas por 0, 15, 30, 45 e 60 dias à temperatura ambiente. A interação entre doses e tempo de armazenamento foi significativa. Melhor qualidade visual foi observada em frutos irradiados com as doses mais elevadas, nos primeiros dias de armazenamento. O índice de acidez do óleo de frutos irradiados foram menores que o tratamento controle, sendo a dose de 10,0 kGy a que propiciou maior redução desse índice. A radiação gama reduziu o acúmulo de óleo e a estabilidade oxidativa no mesocarpo. O teor de água no óleo do mesocarpo aumentou com o incremento das doses e do tempo de armazenamento. O ácido oleico e o ácido láurico estão presentes em maiores quantidades nos óleos do mesocarpo e da amêndoa, respectivamente. Dentre os principais ácidos graxos presentes no óleo do mesocarpo e da amêndoa, o ácido oleico é o ácido graxo que apresenta maiores variações no decorrer do armazenamento. No segundo experimento, 100 unidades experimentais, compostas por 24 frutos de macaúba cada, foram submetidas a diferentes combinações de temperatura e tempo de secagem: 1) sem secagem dos frutos (SS); 2) secagem em estufa a 45°C por 4 dias (45°C/4d); 3) secagem em estufa a 65°C por 4 dias (65°C/4d); 4) secagem em estufa a 45°C por 8 dias (45°C/8d); 5) secagem em estufa a 65°C por 8 dias (65°C/8d). Após esse tratamento as amostras foram conduzidas ao armazenamento, à temperatura ambiente, por 0, 15, 30, 60 e 120 dias. Houve influência do processo de secagem e do tempo de armazenamento nas características avaliadas. A secagem a 65°C por 8 dias foi eficiente para manter o índice de acidez do óleo do mesocarpo estável durante o armazenamento. A secagem restringiu o acúmulo de óleo no mesocarpo e na amêndoa dos frutos. A estabilidade oxidativa foi reduzida pelo tratamento de secagem. Maiores concentrações de ácidos graxos oleico e láurico foram encontrados nos óleos do mesocarpo e da amêndoa, respectivamente. As variações observadas no óleo da amêndoa foram de menor intensidade que as obtidas no óleo do mesocarpo, sendo que o ácido oleico é o ácido graxo mais susceptível à variação ao longo do armazenamento. Nos dois experimentos conduzidos, os tratamentos físicos de radiação gama e secagem ajudaram na conservação do fruto em pós-colheita. Ambos apresentaram menores progressões do índice de acidez em relação ao tratamento controle, durante o armazenamento, porém o tratamento com secagem foi mais eficiente no controle da acidez do óleo dos frutos. O acúmulo de óleo e a estabilidade oxidativa foram reduzidos em ambos os tratamentos. O tratamento de secagem proporciona menores variações no perfil de ácidos graxos, tanto para o óleo do mesocarpo, quanto para o óleo da amêndoa.

O presente estudo foi realizado com os objetivos principais de: verificar as associações existentes entre caracteres agronômicos e caracteres relacionados à qualidade fisiológica de sementes de soja; determinar alterações fisiológicas e no teor de óleo em sementes de soja, ao longo do período de armazenamento, além de selecionar progênies superiores de soja por meio de análises multivariadas. Para isto, as relações existentes entre os caracteres agronômicos de plantas e fisiológicos de sementes foram verificadas por meio da análise de correlações canônicas em sete populações e duas cultivares comerciais, em três gerações: plantas F3 e sementes F4; plantas F4 e sementes F5; e sementes e plantas na geração F4. Os caracteres agronômicos de plantas (grupo I) avaliados foram: número de dias para maturidade, altura da planta na maturidade, altura de inserção da primeira vagem, número de vagens, produção de grãos e teor de óleo. A qualidade fisiológica das sementes (grupo II), foi avaliada por meio do teste de germinação, envelhecimento acelerado, emergência e índice de velocidade de emergência. As mesmas populações e cultivares também foram avaliadas antes do armazenamento e após seis meses, armazenadas em ambiente com temperatura e umidade controladas, através de testes de germinação, vigor, teor de água e teor de óleo, em esquema fatorial 2 x 9. Para as análises multivariadas, 20 populações segregantes de geração F4, foram avaliadas para os seguintes caracteres agronômicos: número de dias para florescimento, número de dias para maturidade, altura da planta na maturidade, altura da inserção da primeira vagem, número de ramos, número de vagens, número de nós, produção de grãos e teor de óleo. Utilizou-se a técnica de componentes principais e análise de agrupamento pelo método não hierárquico de k-médias, além dos índices de seleção Mulamba e Mock e Smith e Hazel. Observou-se que os caracteres agronômicos de plantas e fisiológicos de sementes não são independentes. As associações intergrupos para a geração de plantas F3 e sementes F4 foram estabelecidas por plantas com maior número de vagens, mais produtivas e com alto teor de óleo, as quais estão associadas com sementes de alta germinação e velocidade de emergência. Na geração de plantas F4 e sementes F5, há associação entre ciclo de maturidade reduzido, sementes de alta porcentagem de emergência e alta porcentagem de plântulas normais após o envelhecimento acelerado. Pelo segundo par canônico plantas mais produtivas e de porte alto estão associadas com maior vigor de sementes de soja. Para a geração de sementes e plantas F4 as associações estabelecidas foram sementes de alto vigor estão associadas a plantas mais produtivas, com alto teor de óleo e ciclo de maturidade reduzido. E pelo segundo par canônico há associação entre sementes de alta qualidade fisiológica e plantas de porte alto. O armazenamento das sementes por seis meses em ambiente controlado afetou a qualidade fisiológica e o teor de óleo das sementes, sendo que os genótipos de soja apresentam diferentes níveis de tolerância ao armazenamento e teores de óleo. A análise de componentes principais resultou em 3 componentes principais (CP1, CP2 e CP3), os quais explicam 65,82% da variância total contida nas nove variáveis. Os caracteres de maior contribuição na discriminação dos genótipos em CP1 foram produção de grãos, número de ramos, número de vagens, número de nós e número de dias para maturidade. As progênies selecionadas 36, 37, 38, 39, 40, 41, 65, 75, 80, 89 e 95 apresentam bom potencial produtivo.

This study aimed to examine the associations between agronomic traits and traits related to physiological seed quality in soybean seeds, determine physiological and oil content alterations during the storage and select superior progenies using multivariate analysis. For this, the relationships between agronomic traits and physiological of seed traits were evaluated using canonical correlation analysis in seven segregating populations and two commercial cultivars conducted in three generations: plants F3 and seeds F4, plants F4 and seeds F5 and seeds and plants in generation F4. The agronomic traits (group I) evaluated were: number of days to maturity, plant height at maturity, first pod height, number of pod per plant, grain yield and oil content. The seed physiological quality (group II) was evaluated by percentage of germination, percentage of emergence, emergence speed index and accelerated aging. The same populations and cultivars were also evaluated before the storage and after six months stored in cold room by germination test, vigor, seed moisture and oil content, arranged in a 2 x 9 factorial design. For the multivariate analysis, 20 segregating populations in generation F4 were evaluated using the following agronomic traits: number of days to flowering, number of days to maturity, plant height at maturity, first pod height, number of branches per plant, number of pod per plant, number of nodes per plant, grain yield and oil content. It was used the principal components technique and the non-hierarchical clustering method of k-means and also the rank summation index Mulamba and Mock and classical selection index Smith and Hazel. The analysis of canonical correlation showed that the groups are not independent. Inter-group associations, in the generation of plants F3 and seeds F4, were establish by plants with more pods, higher grain yield and oil content are associated with seeds with high germination and emergence speed index. For the generation plants F4 and seeds F5, there are associations between short-season plants, seeds with high emergence and percentage of germination under conditions of accelerated aging. In the second canonical pair, higher-yielding and taller plants are associated with high vigor soybean seeds. For the generation seeds and plants F4 the associations established were, seeds with high vigor are associated with short-season and higher-yielding plants and high oil content. And in the second canonical pair there is association between seeds with high physiological quality and tall plants. The storage for six months in cold room affected the physiological quality and the oil content of the seeds and the soybean genotypes shown different levels of tolerance of storage and different oil content. The principal components analysis resulted on 3 principal components (PC1, PC2 and PC3), which explained 65,82% of the total variance in nine variables. The traits with higher contribution to discriminate the progenies in PC1 were grain yield, number of branches, number of pods, number of nodes and number of days to maturity. The selected progenies 36, 37, 38, 39, 40, 41, 65, 75, 80, 89 and 95 shown good productive potencial. The clustering analysis, k-means allowed the formation of nine groups, the superior group contains the progenies 36, 38, 39, 40, 65, 75, 79 and 80. Among the 18 progenies selected by the selection indexes, 10 were consistent with principal components analysis. The multivariate analysis allowed selecting superior progenies for the evaluated characters, especially for the components related to grain production and oil content.

Abstract:
Since the dawn of agriculture man has been genetically modifying crop plants to increase yield, quality and utility. In addition to selective breeding and hybridization we can utilize mutant populations and biotechnology to have greater control over crop plant modification than ever before. Increasing the production of plant oils such as soybean oil as a renewable resource for food and fuel is valuable. Successful breeding for higher oil levels in soybean, however, usually results in reduced protein, a second valuable seed component. We show that by manipulating a highly active acyl-CoA: diacylglycerol acyltransferase (DGAT) the hydrocarbon flux to oil in oilseeds can be increased without reducing the protein component. Compared to other plant DGATs, a DGAT from Vernonia galamensis (VgDGAT1A) produces much higher oil synthesis and accumulation activity in yeast, insect cells and soybean. Soybean lines expressing VgDGAT1A show a 4% increase in oil content without reductions in seed protein contents or yield per unit land area. Furthermore, we have screened a soybean fast neutrino population derived from M92-220 variety and found three high oil mutants that do not have reduced levels of protein. From the F2 plant populations we quantitatively pooled the high oil and low oil plants and performed comparative genomics hybridization (CGH). From the data it appears that two families have a 0.3 kb aberration in chromosome 14. We are performing further analysis to study this aberration and develop markers for molecular breeding. Mutagenic techniques are also useful for developing other traits such as early flowering varieties and adapting new high oil crops to a new region. Chia (Salvia hispanica) is an ancient crop that has experienced an agricultural resurgence in recent decades due to the high omega 3 fatty acid (ω-3) content of the seeds and good production potential. The area of cultivation has been expanded to Kentucky using mutagenized populations and the composition traits are similar to that of the original regions of cultivation in Central and South America.

Abstract:
Olive (Olea europaea, Z.), an evergreen tree has been cultivated for thousands years, in many semi-arid and arid mountainous areas surrounding the Mediterranean Sea. Olive oil is extracted from the olive fruit by mechanical means, without any chemical treatment thus preserving all of its natural constituents, which are responsible for the unique flavor, as appreciated by consumers. This thesis concentrates on the important factors that might affect the quality of olive oil. These comprise: cultivar / agricultural methods / weather / processing / storage. Of the quantitative and qualitative results obtained, the following are of particular interest. The olive variety influenced the chemical composition and sensory quality of the olive oil. Particularly affected were the composition of fatty acids, sterols, aliphatic and triterpene alcohols, phenolic compounds and sensory attributes. Osmotic stress, due to no irrigation or to saline irrigation, influenced the size and oil content of the fruit and the composition of triacylglycerol molecular species, fatty acids, total phenols, secoiridoid derivatives as well as volatile compounds and sensory attributes of olive oil The processing methods affected the sensory quality and the phenolic compounds of olive oil. The most significant variations occured mainly due to the quantity of water added to the system of extraction and the duration and temperature of malaxation. The alteration of these during the extraction process was reflected in oxidative processes. The rate of olive oil oxidation was a function of both the time and the various conditions of storage. Virgin olive oil keeps its qualitative characteristics under the category of extra virgin olive oil for 15 months if it is stored in tin containers indoors at room temperature and with nitrogen in the headspace. The present studies provide information for the olive oil industry in order to improve the overall olive oil quality by optimising each step of the production chain.

Abstract:
Triacylglycerols (TAGs) are stored in variable amounts (1-90 % by dry weight) in seed and non-seed tissues of various plant species. To gain insights into tissue- and species-specific regulation and biosynthesis of TAG in plants, we used 454 pyro and Illumina sequencing and generated transcriptome for eight species (brassica, castor, nasturtium, euonymus, oil palm, date palm, and avocado). In all tissues analyzed, an increased expression was noted for genes mostly associated with fatty acid biosynthesis in plastid, but much less increase in those for TAG assembly in the endoplasmic reticulum. Furthermore, hexose metabolism in plastid, relative to cytosol, appeared to be crucial in most oil-rich tissues, which is likely associated with directing high pyruvate flux toward plastid fatty acid synthesis. We also identified that WRINKLED1 transcription factor acts as a master switch in regulating oil biosynthesis in most oil-rich seed and non-seed tissues of monocot and dicot plants, suggesting a highly conserved mechanism. Overall, our studies point to distinctive modes of regulation of fatty acid biosynthesis and TAG assembly that are conserved in both seed and non-seed oil-rich plants, which can be extended to other crops for the purpose of generating biofuels.

Abstract:
Novelty of the research. The investigation focused on five oil pumpkin varieties. Biochemical composition, sensory characteristics and nutritious value of oil pumpkin seeds as well as of oil, seed cake and fruit cake were established and compared in in the course of this investigation. This work established differencies among the genotype of varieties and correlative dependencies between chemical composition indices of pulp, seeds and oil of some pumpkins and meteorological conditions (duration of sunshine, precipitation, temperature). Chemical composition of oil pumpkin fruit pulp and oil depends on the variety genotipe. Meteorological conditions had stronger influence on chemical composition of oil pumpkin seeds than on that of their pulp: amounts of raw, NDF and MADF cellular tissues, raw proteins and crude fats were influenced by duration of sunshine and sum of active temperatures. Amount of precipitation stimulated accumulation of raw and NDF cellular tissue only. Practical value of the work. Big amount of valuable proteins, fats and mineral materials makes pulp, seeds, oil and cake of oil pumpkin fruits an alternative plant raw material for food and/or additive for development of innovative products.

Abstract:
The paper provides background on how bilge water has changed over the years and how technology has enabled manufacturers to stay ahead of the curve by borrowing technological breakthroughs from other areas to the measurement of oil content in the marine environment. Light scattering provides today a universal and reliable method, able to measure the wide range of oils present in a wildly variable and unpredictable bilge water mixture. Bilge water regulations were put in place to reduce the potential of harm to the environment from oily bilge water discharges. Regulations require that instruments verify effluent quality continually during the discharge process, which precludes the adoption for shipboard use of standard laboratory style testing with the associated time delays to complete the analysis. Measuring oil content with the light scattering measuring instrument is a tried and tested means for compliant bilge water verification. State of the art instruments employ sophisticated light measuring systems and they use complex algorithms to convert the scattered light pattern values into oil content reading, thereby considering interference from other than oil suspended matter, they prevent harm to the environment from bilge water discharges.

Abstract:
Quality parameters in petroleum products HSD/SKO/MS are being ascertained on the basis of IS standards and accordingly every OMC produces petroleum product. These products are transferred from refinery to receiving terminals through, rail, road or cross country pipelines. In a particular instance, one of the pipeline fed location in BPCL were continuously getting Haziness in diesel batches. This location was Kota terminal in Rajasthan state and the scenario was such that receipts taken through their MMBPL pipeline was Hazy in appearance. The hazy batches were required to keep ideal for almost 3–4 days to clear its appearance, however all other parameters were meeting the QC guidelines / IS standards. The peculiar behavior depicted in HSD batches was only at their end pipeline location (Kota), on other intermediate locations at upstream of Kota location, the same HSD batches were passing the appearance test. The study was undertaken to know the root cause for such phenomenon and on the basis of RCA , corrective action were implemented for altering the manufacturing process of HSD.

The aim of this work is to study the effects of drying conditions on the quality of extracted pricly pear seed oil, specifically α-tocopherol content. Drying experiments were carried on following a full 23 factorial design using a vertical drying tunnel. The temperature range was 45 to 70°C, relative humidity range was 15 - 30% and air velocity was 1 and 2 m/s. The Midilli-Kucuk model was found with satisfaction describing the seed air drying curves with a correlation coefficient of 0.999 and a standard error of 0.01. For each drying condition, the extraction of fixed oil seeds was performed at cold using mechanical pressing method. The oil quality was evaluated on the basis of the a-tocopherol content. The a-tocopherol was identified and quantified by high-performance liquid chromatography (HPLC-UV). According to the experimental results, it was found that convective drying of thin layer of seeds at soft air conditions, drying temperature of 45°C, relative humidity of 15% and air velocity of 1m/s give the optimal quality of extracted oil in terms of a-tocopherol content.Keywords: prickly pear seeds; convective drying; semi-empirical modeling; a-tocopherol seed oil; optimization.

Abstract:
Malaysia has about 4.2 million hectares of oil palm plantation. The palm oil milling industry has over 400 mills throughout the country with total milling capacity of 82 million tonnes fresh fruit bunches, FFB, per year. In 2003, the amount of FFB processed was 67 million tonnes, which generated solid wastes in the forms of empty fruit bunches, EFB (19.43 million tonnes), mesocarp fibres (12.07 million tonnes) and palm kernel shell (4.89 million tonnes). These wastes has moisture content of 60–70% for EFB and mesocarp fibre, and 34–40% for palm kernel shell, and calorific value of 5.0 – 18.0 Mj/kg. A processing technology was developed to process these low quality biomass fuels into high quality solid biofuel briquettes with moisture content in the range 8–12%. Depending on the formulations and the sources of the raw biomass, the final solid biofuel briquettes can have calorific values in the range of 18–25 Mj/kg. The production of the solid biofuel briquettes would be an attractive financial advantage for full exploitation of biomass fuels. Logistic problems due to the disperse nature of the biomass resources would significantly be addressed.

The mechanical properties of welding material is correlative with the diffusible hydrogen content in weld metal and level of moisture content in flux. Minitab16program to predict mechanical properties correlated to diffusible hydrogen content in weld metal and level of moisture content in flux, such as yield strength, tensile strength, elongation and average Charpy impact toughness of welding material is established by using submerged arc welding process in line pipe manufacturing. The present paper aims to experiment and investigate the line pipe SAW Flux used for offshore/onshore applications. Flux moisture content has been studied under Karl Fischer Coulometer method. Subsequently, flux was then used to make weld to analysis for ‘diffusible hydrogen content in weld metal’ through mercury displacement method. This detailed study envisages and explains the correlations between the mechanical properties and micro structures of weldments. Evaluating the variance of moisture level in flux and diffusible hydrogen content in weld metal proves the advantage of restricting the moisture content along with good practices to accomplish better weld quality.

Full text
Abstract:
Abstract Excessive sand production is synonymous with aging fields and increased water production. Some offshore fields in Malaysia produce sand in the range of tonnes per day. Conventionally, the produced sand needs to be sent onshore for treatment, increasing the OPEX for a field with an already declining production. This paper presents a newly developed technology to help operators in handling and disposal of produced sand offshore. A hybrid system of a unique mechanical agitation and the chemical solution was developed for offshore sand cleaning. The system aims to remove Oil-in-Water (OIW) and Oil-in-Sand (OIS) content according to the local regulations and requirements for offshore disposal. In the lab-scale screening, the best performing deoiling chemical for oil removal from the sand was achieved using novel chemical formulations containing surfactants with higher water affinity (hydrophilic). In the bench-scale prototype evaluation, the deoiling chemical was coupled with a mechanical system. A semi-automated, pilot-scale unit with the capacity to handle approximately 1 metric tonne of oily sand was constructed and used for further testing. In the lab stage, the sand deoiling formulation was identified and optimized. Up to bench-scale testing, only 30ppm of deoiling chemical is required to clean the field sand to OIS of <1wt% and OIW of less than 40ppm. The effectiveness of mechanical agitation and low dosage of chemical deoiling is further proven via testing using the pilot-scale unit. It has been shown that a superior cleaning quality meeting the onboard disposal specification can be achieved via this system compared to existing technology which is based on only mechanical means. An example of potential sand cleaning system integration and tie-in to an existing offshore facility with excessive sand production is also discussed in this work. The compact sand cleaning system is a novel technology to reduce OIS content, leading to reduced sand handling and disposal OPEX for aging fields.

The accurate measurement of water content in the turbine oil has great significant for guiding steam turbine safety and economy running. A method of the on-line measurement of the water content in the turbine oil based on microwave resonant cavity perturbation is presented in this paper, The author deduced the formula of the volume proportion of water content in turbine oil, the resonant cavity and the measuring system of this method is simple. The precision of measurement can be improved by selecting work pattern with high quality factor, advancing the measurement precision of the relative frequency deflection and adopting the lower thermal expansion coefficient material and the especial resonant cavity configuration. Ten PPM water content in turbine oil can be distinguished by this method.

Abstract:
The lubricating properties of vegetable oil are well known. However, with the advent of petroleum oils, castor oil and other vegetable oils fell out of favor. The quality of petroleum oils has improved significantly in the last few years with the introduction of Group III base oils. However, even Group III oils fall short of the inherent lubricity of vegetable oils. Analogous to advances in petroleum oils, improvement of vegetable oils by genetic modification to obtain high oleic oils has led to better acceptance of these oils as lubricants. Studies have shown significant reduction in tail pipe emissions when using these types of oils in an engine crank case. We have successfully expressed a hydroxylase gene in a high oleic canola variety. The combination of a high oleic background and hydroxy fatty acids produced an oil with properties that improve further on high oleic oils. The presence of the hydroxy group provides improved lubricity. This technology will allow us to create oils with varying hydroxy fatty acid content depending on the application. These applications can range from use in lubricants, as chemical feedstocks, and reactive components in polymers.
