OBJECTIVE: The objective of this study was to investigate the effect of frying oils (canola, hydrogenated sunflower and soybean oils) available commercially and chill storage on the proximate and fatty acid composition of fried slices of farmed great sturgeon (Huso huso). METHODS: Slices of farmed great sturgeon were fried for four minutes at 160ºC in a deep-fryer using different frying oils (canola, hydrogenated sunflower and soybean oils). The oil-to-slice ratio was 2:1. After frying, the slices were allowed to be air cooled for two minutes prior to analysis. For performing the analysis, each of the abovementioned batches was divided into two groups: one group was analysed immediately after frying and the second group was chill-stored at 4ºC for three days and then analysed. RESULTS: After frying, the moisture content decreased while that of fat increased. Fatty acid composition of the slices is affected by type of frying oil. Frying increased the omega-6-to-omega-3 (n-6:n-3) fatty acid ratio while decreased Eicosapentaenoic Acid (C20:5 n-3) and Docosahexaenoic Acid (C22:6 n-3) contents. Proximate and fatty acid composition of raw slices did not change after chill storage. However, in fried- and chill-stored slices, Eicosapentaenoic Acid and Docosahexaenoic Acid contents decreased, while linoleic acid content increased. CONCLUSION: The fatty acid composition of the fried slices tended to resemble that of the frying oils, indicating fatty-acid equilibrium between oils and slices and, during chill storage, it is influenced by the type of frying oil. Slices fried with canola oil had omega-6-to-omega-3 ratios in the ranges recommended for human health.

Genus Capsicum

Fatty acids have a great metabolic and structural importance. Evaluation of fatty acid composition of peppers is still incomplete. Pulps and seeds from six varieties of the genus Capsicum were evaluated in this work with respect to their contents in fatty acids. A total of 25 different fatty acids, including some with odd number of carbons were identified in the samples. The most abundant fatty acids were palmitic (16:0), oleic (18:1n-9) and linoleic (18:2n-6) acids. The polyunsaturated:saturated fatty acid (PUFA/SFA) ratios for all peppers were high due to the elevated amounts of polyunsaturated acids, particularly linoleic acid. In the pulps, the omega-6/omega-3 ratios ranging from 1.28 to 4.33, were relatively adequate if one considers that ratios between 0.25 and 1.0 in the human diet are regarded as highly appropriate. In the seeds, the levels of omega-3 were very low whereas the levels of omega-6 were high, leading to very inadequate omega-6/omega-3 ratios ranging from 74.2 to 279.6. Principal component analysis (PCA) explained 93.49% of the total variance of the data. Considering the PUFA/SFA ratio and omega-6/omega-3 ratio, our data suggest that, among the peppers of the genus Capsicum evaluated in this work, the bell pepper and orange habanero pepper present the best nutritional characteristics concerning fatty acid composition.

An experiment was carried out to determine the effects of dietary supplementation of Albizia lebbeck seed oil (ALO) on the fatty acid composition of weaner rabbits.50 weaned rabbits of mixed breed and sexes, aged between 6-7 weeks with an average initial body weight of 460 ± 1.3 were randomly assigned into five dietary treatments of ten rabbits per group; each group was further divided into 5 replicates consisting of two rabbits each. Basal diet was formulated to meet the nutritional requirements of rabbits according to NRC (1977). Rabbits in treatment 1, 2, 3, 4 and 5 were supplemented with ALO at 0 %, 0.1%, 0.2 %, 0.3 % and 0.4 % respectively. Feed and water was given ad libitum and the experiment lasted for 12 weeks.The results showed that significant differences (P<0.05) were observed in saturated fatty acid (SFA), polyunsaturated fatty acid (PUFA) and omega-6/omega -3 ratio (n-6:n-3) values obtained. Rabbits fed diet containing 0.4 % ALO had the highest PUFA value (54.17 %), followed by T4 (53.01 %), T3 (45.13 %), T2 (37.61 %) and T1 (26.93 %) respectively. Similarly (n-6:n-3) composition in T5 (3.65 %) increased in T5 fed 0.4 % ALO compared with T1 (1.38 %) fed 0% ALO.Antherogenic index were significantly (P<0.05) different among the treatments. It can be concluded that supplementation of ALO at 0.4 % highly influenced the composition of fatty acid in rabbit meat.

The article analyzes the fatty acid composition of the frozen iwashi lipids of different shelf lives. It is established that the total amount of essential fatty acids omega-3 and omega-6 in iwashi’s fat reaches almost 90% of all polyunsaturated fatty acids and remains practically unchanged for 12 months of fish cold storage. It is shown that products from iwashi contain a significant amount of essential fatty acids, indispensable for the human body, which can be used to optimize the population nutrition and satisfy the physiological needs in eicosopentaenoic and docosahexaenoic fatty acids.

Fatty acid composition in chicken fast food was analyzed by attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy and gas chromatography-flame ionization detector (GC-FID). Saturated fatty acids (SFA), monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) have been found in various amounts in the fast food samples. None of the fast food samples contain trans fatty acid. Chicken Winglet (A) and Chicken Hot Wings (B) have higher amount of saturated fatty acids (SFA) which are 28.73% and 25.92% respectively. The amount of saturated fatty acids (SFA) in Chicken Drumst (C), Chicken Botik (D), Fiery Grilled Chicken (E), Chicken Meatballs (F), and Chicken Nuggets (G) are in between 10.94-19.38%. The saturated fatty acids found in the fast food samples are palmitic acid, stearic acid, and myristic acid. Highest amount of linoleic acid (omega-6, 18.90%) was found in Chicken Meatballs (F). The ratio of omega-6 and omega-3 in sample D was 2.32:1 which is in the acceptable range. Although trans fatty acid was not found in the samples, presence of more than 10% saturated fatty acids in chicken fast food is still harmful for health as it may increase risk of cardiovascular disease (CVD).

The article presents the results of the study on fatty acids content of broiler chickens purchased from retailers and broiler chickens grown in organic farming. In the study we compared the obtained results. There are also results of the influence of developed preventive drug postbiotic on the fatty acid composition of broiler chickens. The samples were compared in terms of their nutritional value and quality. Chicken that goes into the retail network is obtained from broiler chickens grown in a traditional (intensive) technological way. Organic poultry is extensive. For the experiment in organic farming, we formed the 2 groups (control and experiment). In the experimental group, broiler chickens received a prophylactic preparation - a postbiotic with organic feed, and no drugs were used in the control. In-depth studies of the mechanisms of its effect on the body of chickens and the quality of the products obtained were studied changes in the fatty acid composition of total lipids in skeletal muscle and the biochemical composition of the muscle tissue of chickens. There were no significant changes in the fatty acid content of the tested meat compared with the control group. The content of palmitoleic, linoleic and caprylic acids is slightly increased. The fat content of heavy broiler chickens is much higher than that of broiler chickens. The best fatty acid ratio of omega-3 and omega-6 is found in organic chicken meat. Retail chicken meat has a lower omega 6 content, significantly higher than palmitic acid omega 3. Organic chicken meat contains 3-5% less fat compared to retail chicken. In the meat of chickens grown using organic technology, the amount of saturated fatty acids increased significantly by 11.13%, there is a significant decrease in omega-6 fatty acids by 7.57% and an increase in the amount of omega-3 fatty acids by 0.8% compared to with chicken from the retail chain. Therefore, the value of organic chicken meat lies not only in the absence of residues of antibiotic substances, pesticides and herbicides, but also in its biological value and dietary properties.

AbstractA twelve-month study was conducted on changes in fatty acid composition and pesticide residues in honeybees and beebread. In honeybees, saturated fatty acid and monounsaturated fatty acid gradually increased as summer began then decreased when spring started, and polyunsaturated fatty acid had an opposite seasonal trend. Similar fluctuation was observed in the beebread collected from the same hive as those honeybees through summer to fall, especially in the essential fatty acids omega-6 and omega-3. Honeybees’ lipid metabolism can be disrupted after being exposed to a sub-lethal level of pesticide. Although three out of sixteen analyzed pesticides were detected in beebread samples summer through fall in our study, we were not able to find any negative affect of those pesticides on the honeybees’ fatty acid composition. Temporary field-realistic pesticide exposure may weaken honeybees but are unlikely to show any reflection in their fat bodies if the colony was otherwise healthy.
