The seed oil of “batuan” [Garcinia binucao (Blco.) Choisy] fruit, an indigenous, lesser known, and with promising economic potential, was characterized to evaluate its quality and potential for product development. Using standard AOAC methods, thin layer chromatography and gas chromatography, the physicochemical properties, lipid and fatty acid profile were determined. Oil yield from “batuan” seeds was high. The extracted oil was yellowish white, soft solid at room temperature. Iodine value, acid value, and peroxide value of the seed oil were low while saponification value was high. Lipid presents in “batuan” seed oil is mostly triglycerides while diglycerides are in low amount. Unsaponifiable matter (<1.0%) was abundant in sterol, squalene and beta-carotene, and minor amount of Vit. A palmitate, and-tocopherols. Stearic (C18:0), oleic (C18:1), and palmitic (C16:0) acids were the major fatty acids while arachidic, linoleic and linolenic acids constitute the minor components. “Batuan” seed oil contained more saturated fatty acids than the unsaturated fatty acids which could be responsible for its being a soft solid at room temperature. Results of this study show that “batuan” seed oil is of good quality and could be a potential source of valuable oil for food and other industrial applications.

Palado (Aglaia sp) is a plant that grows wild in the forest around Mamuju regency of West Sulawesi, Indonesia. This plant is locally known as palado. Palado seeds (Aglaia sp) can be used as a source of vegetable oil because it contains approximately 14.75 % oil, and it has the potential to be used as food ingredients or as raw material for oil production. The purpose of this study was to determine the chemical properties and the composition of fatty acids contained in palado seed oil (Aglaia sp). The employed method involved the use of palado fruit that had been processed to be palado seed and undergoing flouring process. Palado flour was produced by the extraction process by using chloroform solvent with the soxhlet method. The characteristics of the chemical properties in the oil produced were analyzed by using a standard method, including iodine, saponification, and acid values. The analysis of fatty acid composition was conducted by using gas chromatography. The results showed that palado oil extracted with hexane had an iodine value of 15.38 mg/g, saponification value of 190.01 mg KOH/g, and acids value of 1.961 mg KOH/g. The fatty acid composition of the palado seed oil consisted of saturated fatty acids (41.601 %), which included palmitic acid (41.062 %), myristic acid (0.539 %), and unsaturated fatty acids (45.949 %), which included mono-unsaturated fatty acids (MUFA) such as (22.929 %), oleic acid and poly-unsaturated fatty acids (PUFA), which was linoleic acid (23.020 %).

Abstract Indian major carps are the widely consumed fish species of Pakistan, being a cheap source of proteins and unsaturated fatty acids, they are good for cardiovascular health. Water pollution due to discharge of untreated industrial waste water into water bodies contaminates this precious source of nutrients. The present study therefore, was aimed to assess deterioration of fatty acid profile of three Indian major carp species due to different concentrations of industrial wastes. The water samples were collected from the river Chenab at the site where it receives industrial wastewater via Chakbandi drain. After exposure to 1.5%, 3.0%, and 4.5% dilutions of collected water in different aquaria it was observed that proportion of unsaturated fatty acids in selected fish species were decreased significantly as the intensity of the dose increased (P < 0.05). Conversely the level of saturated fatty acids increased with the increasing dose of treatment (P < 0.05). These findings suggest that untreated wastewater not only deteriorate the fatty acid profile of aquatic animals but also these toxic substances can reach human body through fish meat and pose further health hazards. Therefore, it is highly recommended that industrial effluents should be treated before they are dumped into water bodies.

Seed oil composition, an important agronomic trait in cultivated sunflower, varies latitudinally across the native range of its wild progenitor. This pattern is thought to be driven by selection for a higher proportion of saturated fatty acids in southern populations compared to northern populations, likely due to the different temperatures experienced during seed germination. To investigate whether these differences in fatty acid composition between northern and southern populations correspond to transcriptional variation in the expression of genes involved in fatty acid metabolism, we sequenced RNA from developing seeds of sunflowers from Texas, USA and Saskatchewan, Canada (the extreme ends of sunflower's latitudinal range) grown in a common garden. Over 4,000 genes were found to be differentially expressed between Texas and Canada, including several genes involved in lipid metabolism. Many differentially expressed oil metabolism genes colocalized with known oil QTL. The genes producing stearoyl-ACP-desaturases (SAD) were of particular interest because of their known role in the conversion of fully saturated into unsaturated fatty acids. Two SAD genes were more highly expressed in seeds from Canadian populations, consistent with the observation of increased levels of unsaturated fatty acids in seeds from that region. We also constructed a gene co-expression network to investigate regional variation in network modules. The results of this analysis revealed regional differentiation for eight of twelve modules, but no clear relationship with oil biosynthesis. Overall, the differential expression of SAD genes offers a partial explanation for the observed differences in seed oil composition between Texas and Canada, while the expression patterns of other metabolic genes suggest complex regulation of fatty acid production and usage across latitudes.

The present study was aimed at analyzing the fatty acid composition, tocopherols, and physico-chemical characterization of wood apple (Limonia acidissima L.) seed oil and the nutritional profile of seed cake. The fatty acids in seed oil were analyzed by gas chromatography–mass spectrometry (GC-MS), and the total seed oil was 32.02 ± 0.08%, comprising oleic (21.56 ± 0.57%), alpha-linolenic (16.28 ± 0.29%), and linoleic acid (10.02 ± 0.43%), whereas saturated fatty acid content was 33.38 ± 0.60% including palmitic (17.68 ± 0.65%) and stearic acid (14.15 ± 0.27%). A greater amount of unsaturated fatty acids (52.37%) were noticed compared to saturated fatty acids (33.38%); hence the seed is highly suitable for nutritional and industrial applications. Gamma-tocopherol was present in a higher quantity (39.27 ± 0.07 mg/100 g) as compared to alpha (12.64 ± 0.01 mg/100 g) and delta (3.77 ± 0.00 mg/100 g) tocopherols, which are considered as natural antioxidants. The spectrophotometric technique was used for quantitative analysis of total phenolic content, and it revealed 135.42 ± 1.47 mg gallic acid equivalent /100 g DW in seed cake. All the results of the studied seed oil and cake showed a good source of natural functional ingredients for several health benefits.

Aim: To ascertain the effects of boiling and fermentation on the physicochemical properties, fatty acid, mineral and vitamin composition of Hibiscus sabdariffa (HS) seeds. Study Design: Completely randomized design Place and Duration of Study: Rivers and Anambra states, Nigeria, between February and September, 2018. Methodology: Two portions of 200 grams of HS seeds each were subjected to boiling and fermentation. The three samples were designated HSR, HSB and HSF for raw, boiled and fermented HS seeds respectively. Standard methods were used in determining the physicochemical properties and micronutrient composition, while fatty acid constituents were identified using a gas chromatography. Results: The acid, free fatty acid, peroxidase values and specific gravity were significantly increased (p<0.05), while iodine value was significantly reduced (p<0.05) after boiling and fermentation. Saponification value showed a mixed trend, while refractive index was not significantly (p>0.05) altered. Lauric (5.51–33.79%), palmitic (27.23–30.87%) and myristic (12.69–35.00%) acids were the predominant saturated fatty acids in HSR, HSB and HSF samples respectively. Oleic, linoleic, alpha-linolenic and arachidonic acids were the unsaturated fatty acids present in the samples. Boiling increased oleic acid level, while fermentation caused a drastic reduction (>90%) in its amount. Linoleic acid level improved up to 43% after fermentation. Magnesium, iron and sodium amounts significantly (p<0.05) reduced after boiling and fermentation, while zinc, calcium and molybdenum levels were significantly (p<0.05) improved after boiling. Na/K ratios for all the samples were greater than 0.60, while Ca/Mg values ranged between 0.82 and 3.46, below the recommended value (1.0). Vitamins B1, B3, B12 and D were significantly reduced (p<0.05) after boiling and fermentation, while fermentation significantly increased (p<0.05) vitamins B2, A, E and K levels. Conclusion: HS seeds were shown to possess good physicochemical properties that can enhance its utility in the industry. Boiling and fermentation maximized the usefulness of HS seeds as quality nutritional plant.

The objective of this work was to investigate the fatty acid composition and assess hygienic quality of the Algerian camel milk from Targui breed, then to compare obtained results with cow milk in local rearing conditions. Sampling was performed over three months at a rate of one sample per month. The physicochemical analyzes carried out revealed that the Targui camel milk had averages values of 6.33 ± 0.15 for the pH, acidity equal to 18.50 ± 0.02 °D, and 1030.40 ± 1.08 for density. The total dry extract and the fat levels were lower than those of cow milk. In addition, results of fatty acid profile analysis from camel milk revealed a relatively low level of saturated fatty acids (SFAs) compared to cow milk, palmitic acid (C16:0) being the predominant fatty acid in both milks. The content of unsaturated fatty acids (UFAs) was significantly higher in camel milk fat compared with cow milk, with higher total monounsaturated fatty acids (MUFAs) rate in camel milk. Oleic acid (C18:1 n9) was in the same proportions, and the most abundant unsaturated fatty acid in both species. However, no significantly difference was observed between PUFAs levels of camel and cow milk. Linoleic acid (C18:2 n6) was the most represented polyunsaturated fatty acid in both milks with similar proportions. In contrast, the content of α-linolenic acid (C18:3 n3) was significantly (p<0.001) higher in cow milk than in camel one.

Abstract The aim of the study was to determine the impact pike fishing season (before spawning in fall (group A) and after spawning in spring (group B)) had on the slaughter yield and fillet fatty acid profile. The slaughter yield of fillets with skin and skinned fillets from the group B fish was significantly lower (by approximately 7.5% of body weight). The fatty acid profile of the fish meat from the groups examined differed significantly. The fillets of pike caught before spawning were dominated by unsaturated fatty acids (UFA), while those from fish caught after spawning had mainly saturated fatty acids (SFA). The share of polyunsaturated fatty acids (PUFA) in the fillets of fish that had spawned was sixfold lower, and the n-3 PUFA differences were nearly ninefold. The content of eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids in fillets of fish that had spawned was ninefold lower than in those that had not yet done so. Consequently, the ratio of n-3 PUFA/n-6 PUFA in pike from group A was over three times higher than that in the fish that had spawned (2.61 vs 0.82). Fillets from pike that have spawned are a significantly poorer source of valuable fatty acids for consumers.

Background: Sheep milk production is becoming an important alternative in the agricultural sector. It is used principally to produce fine cheeses, yogurts, and ice creams, and these produced from sheep’s milk are beneficial to human health. Previous study with palm oil shows increase in fat levels in sheep’s milk. Our hypothesis for increased fat in milk is that palm oil increases lipid metabolism as well as tissue reserves. Sheep consuming this palm oil will have a change in the fatty acid profile of milk, increasing levels of unsaturated fatty acids. Therefore, the aim of this study was to determine the levels of cholesterol and triglycerides, as well as fatty acid profile of milk these ewes fed of palm oil.Materials, Methods & Results: Thirty-six lactating sheep were divided in four groups (n = 9), with each group receiving various concentrations of palm oil in diet (0%, 2%, 4%, and 6% which corresponds to T 0, 2, 4 and 6, respectively). The diets in each treatment were isoproteic and isoenergetic. The experiment lasted 120 days, and blood and milk samples were collected on days 60 and 12 of the experiment. Blood was collected for seric analysis of lipid metabolism. Was collected milk samples and analyzed the content of saturated fatty acids (SFAs), monounsaturated fatty acids (MUFA), and polyunsaturated fatty acids (PUFA). An increase (P < 0.05) in triglyceride and coleterol levels in the serum of the animals that received the highest concentrations of palm oil in the diet (T4 and T6). The centesimal composition of fat, lactose, and protein in milk was not different at days 60 and 120 (P > 0.05) between groups, but numerically the animals in T4 and T6 had higher percentage of fat in milk. A decrease in milk SFA levels was observed on day 120 at T6. There was a significant reduction in caproic acid, caprylic acid, hendecanoic acid, lauric acid, and pentadecyl acid. The levels of palmitic acid (C16:0) increased when compared with the control group. Also at 150 days, it was observed a reduction in the percentage of area capric acid and myristic acid in animals that had higher doses of calcium salts in the diet, different from stearic acid, which increased. A variability in MUFA levels was observed during the evaluated periods, i.e. heptadecenoic acid decreased on days 60 and 120 for animals of T6; an increased content of elaidic acid was observed on day 60, and levels of vaccenic acid decreased on day 120 at 6% palm oil. A decrease in PUFA levels was observed on day 60 at T6, specifically a significant reduction in alpha-linolenic and arachidonic acid, as well as levels of conjugated linoleic acid 1 decreased on day 120 for animals supplemented with 6% of palm oil.Discussion: The addition of plama oil in the diet of dairy sheep increased seric levels of triglycerides and cholesterol, as well as positively altered the composition of fatty acids in milk, making a product healthier to the consumer. This study showed that the addition of 2% and 4% palm oil in the feed of dairy sheep promoted a decrease in several SFAs associated with coronoary heart disease after 60 days of treatment. On the other hand, the addition of 6% palm oil promoted an increase of total SFA levels after 60 days of treatment, while decreaseing total PUFA levels. This can be considered harmful to consumers, since several SFA are associated with coronary heart diseases, and several PUFA are linked with reductions in inflammation, stroke, oxidative stress and hepatic disorders. In summary, the consumption of sheep milk who received the diets with 2% and 4% of palm oil can exert beneficial effects for consumers, and may be an option for farmers to increase the milk yield of sheep, and to reduce the profile of saturated fatty acids in milk.
