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).

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.

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.

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.

Flax Oil

The creation of new types of dairy products for functional purposes with the addition of unconventional oils as sources of polyunsaturated fatty acids (PUFA) is a promising and relevant research sphere. The study aimed to investigate the fatty acid composition of experimental samples of curd spread with different content of flax oil. The fatty acid composition was determined on a Hewlett Packard HP-6890 chromatograph with a flame ionization detector equipped with a 100 m long SP-2560 capillary column. It is established, that the total content of saturated fatty acids in curd spread containing 8 %, 10 %, and 12 % of flax oil was reduced, and the general total content of unsaturated fatty acids increased accordingly by 5.73 %, 6.94 % and 7.31 %, compared to the control sample without flax oil. The gas-chromatographic analysis showed that flax oil is rich in omega-3 PUFA due to its high content of α-linoleic acid, so adding flax oil to the spread led to an increase in its content of α-linolenic acid and, accordingly, increased the content of PUFA of the omega-3 family. Thus, adding 8 %, 10 % and 12 % of flax oil to the curd spread, the content of α-linolenic acid in it increased accordingly by 3.91 %, 4.52 %, and 4.69 %, compared to the control sample. Curd spread with 10 % content of flaxseed oil is characterized by the most optimal fatty acid composition. The ratio of saturated fatty acids to unsaturated in this curd spread is 1.9 : 1, and the ratio between PUFAs of the omega-3,-6, and -9 families are 1.3 : 1: 5.3.

The present study analysed fatty acid composition and tocopherol content of raw, curried and fried fish. Of the saturated fatty acids, C12:0, C14:0 and C16:0 had significant increase in fried and curried fish than raw fish. Of monounsaturated fatty acids, C18:19c significantly increased in fried and cooked form whereas polyunsaturated fatty acids, C20: 5n3 (EPA) and C22:6n3 (DHA) showed significant decrease in fried and curried fish. In cooked and fried fish there was significant reduction of tocopherol content. There was increase in hypocholesterolaemic and hypercholesterolaemic fatty acid (HH) ratio in fried and curried fish. Fish fried in coconut oil and fish curry in coconut cream were not found to be healthy processing methods and both processing methods lead to significant reduction in potential health benefits of omega-3 fatty acids in the fishes.

SummaryPlatelet aggregation and its relation to fatty acid composition of platelets, plasma and adipose tissue was determined in 196 randomly selected, free-living, 40-49-year-old men in two regions of Finland (east and southwest) with a nearly twofold difference in the IHD rate.There were no significant east-southwest differences in platelet aggregation induced with ADP, thrombin or epinephrine. ADP-induced platelet secondary aggregation showed significant negative associations with all C20-C22 ω3-fatty acids in platelets (r = -0.26 - -0.40) and with the platelet 20: 5ω3/20: 4ω 6 and ω3/ ω6 ratios, but significant positive correlations with the contents of 18:2 in adipose tissue (r = 0.20) and plasma triglycerides (TG) (r = 0.29). Epinephrine-induced aggregation correlated negatively with 20: 5ω 3 in plasma cholesteryl esters (CE) (r = -0.23) and TG (r = -0.29), and positively with the total percentage of saturated fatty acids in platelets (r = 0.33), but had no significant correlations with any of the ω6-fatty acids. Thrombin-induced aggregation correlated negatively with the ω3/6ω ratio in adipose tissue (r = -0.25) and the 20: 3ω6/20: 4ω 6 ratio in plasma CE (r = -0.27) and free fatty acids (FFA) (r = -0.23), and positively with adipose tissue 18:2 (r = 0.23) and 20:4ω6 (r = 0.22) in plasma phospholipids (PL).The percentages of prostanoid precursors in platelet lipids, i. e. 20: 3ω 6, 20: 4ω 6 and 20 :5ω 3, correlated best with the same fatty acids in plasma CE (r = 0.32 - 0.77) and PL (r = 0.28 - 0.74). Platelet 20: 5ω 3 had highly significant negative correlations with the percentage of 18:2 in adipose tissue and all plasma lipid fractions (r = -0.35 - -0.44).These results suggest that, among a free-living population, relatively small changes in the fatty acid composition of plasma and platelets may be reflected in significant differences in platelet aggregation, and that an increase in linoleate-rich vegetable fat in the diet may not affect platelet function favourably unless it is accompanied by an adequate supply of ω3 fatty acids.

Genetic parameters were estimated for fatty acid composition of subcutaneous beef fat of 1573 animals which were the progeny of 157 sires across seven breeds grown out on pasture and then finished on either grain or grass in northern New South Wales or in central Queensland. There was genetic variation in individual fatty acids with estimates of heritability for the proportions of C14 : 0, C14 : 1c9, C16 : 0, C16 : 1c9, C18 : 0 and C18 : 1c9 fatty acids in subcutaneous beef fat of the order of 0.4 or above. Also substantial correlations between some fatty acids were observed. Genetic correlations between fatty acids and fat depth at the P8 site suggested that much of the genetic variation in fatty acid composition was related to changes in fatness. Selection for decreased fatness resulted in decreased proportions of C18 : 1c9 with concomitant increases in C18 : 0, C14 : 0 and C16 : 0. This suggested that selection for decreased fatness at a given weight will result in a decrease in the proportions of monounsaturated fatty acids in the subcutaneous fat in the carcass with a corresponding increase in the proportions of saturated fatty acids.

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.
