Abstract The aim of the work was to study the effect of different muscles on the fatty acid composition in the intramuscular fat of roe deer hunted in Lithuania. The samples were excised from the five muscles of different carcass sites: m. longissimus dorsi (LD), m. deltoideus (shoulder), m. tensor fascia e latae (hind quarter), m. cleidocipitalis (neck) and m. intercostales interni (brisket) of hunted animals. The data were subjected to the analysis of variance in general linear (GLM Multivariate) procedure in SPSS 17. The muscle location of roe deer males appeared to affect the fatty acid composition in the intramuscular fat. The total proportions of saturated (SFA ), monounsaturated (MUFA ) and polyunsaturated (PUFA), including individual SFA, MUFA and PUFA acids were affected by the muscle. The highest levels of SFA and MUFA and the lowest levels of PUFA were found in the intramuscular fat of neck and brisket muscles and vice versa, the lowest levels of SFA and MUFA and the highest levels of PUFA were found in the intramuscular fat of LD and hind quarter muscles. The muscle type of roe deer appeared to affect the lipid quality indices. The lowest atherogenic and thrombogenic indexes, and the highest hypocholesterolemic/hypercholesterolemic ratio were in the intramuscular fat of LD and hind quarter muscles.

The aim of this study was to provide information on the fatty acid profile of different adipose depots - subcutaneous (upper and inner backfat layers) and intramuscular (m. Longissimus dorsi) in East Balkan pigs. The animals were reared in free-range conditions and slaughtered at an average live weight of 107?1.65kg. The results of the study showed that the various adipose tissues in pigs have different lipid metabolism and hence differ in their fatty acid composition. Intramuscular fat had significantly higher content of the saturated C16:0 and C18:0 (P<0.001), as well as the C16:1 (P<0.001) than the subcutaneous fat. In regards to the content of the polyunsaturated fatty acids, the latter displayed considerably higher content of both C18:2 and C18:3 (P<0.001) in comparison to the intramuscular fat in m. Longissimus dorsi. The differences between the subcutaneous and intramuscular adipose tissue in the individual fatty acids determined the similar trend of change in the total content of saturated and polyunsaturated fatty acids. Significant differences between the backfat layers were detected for C16:1, C18:0 and C18:3 (P<0.001). Stearic acid (C18:0) displayed higher content of the inner, while both C16:1 and C18:3 had higher proportion in the outer backfat layer in the East Balkan pigs. Except for C20:2, the long chain polyunsaturated n-6 and n-3 fatty acids had significantly higher proportions in the intramuscular fat, however no differences were determined between the two backfat layers.

This study aimed to evaluate the fatty acid composition, including the contents, of conjugated linoleic acid cis9trans11 C18:2 (CLA) and trans C18:1 and C18:2 isomers in hard cow, sheep, and goat cheeses found on the Polish market and to compare lipid quality indices in these cheeses. The gas chromatography method was used to determine the fatty acid profile. The study demonstrated various contents of cis9trans 11 C18:2 (CLA), trans C18:1, and C18:2 isomers and the values of lipid quality indices in the cheeses. Sheep and goat cheeses were richer sources of short-chain fatty acids (SCFA) (14.73 ± 2.55% and 14.80 ± 2.80%, respectively) than the cow cheeses (9.38 ± 0.87%). The cow cheeses had a significantly higher (p < 0.05) content of monounsaturated fatty acids (MUFA), the lowest n-6/n-3 ratio, and the highest content of fatty acids, inducing a desirable dietary effect in humans (DFA) compared to the sheep and goat cheeses. Significantly higher (p < 0.05) contents of polyunsaturated fatty acids (PUFA) were found in sheep cheeses. Goat cheeses had the highest n-3 PUFA content and the lowest values of the thrombogenicity index (TI) (2.67 ± 0.44) compared to the sheep and cow cheeses (3.14 ± 0.29 and 3.13 ± 0.13, respectively). The cow, sheep, and goat cheeses were characterized by similar values of the hypocholesterolemic/hypercholesterolemic (H/H) ratio. Sheep cheeses had the highest levels of cis9trans11 C18:2 (CLA) and the highest total content of trans C18:1 and trans C18:2 isomers. The research showed that sheep, cow, and goat cheeses offered various health benefits. The differences in fatty acid composition and the different values of the lipid quality indices found in the cheeses may be due to differences in both the composition of milk used to produce them and the cheese-making technology. Studies conducted by many authors have indicated that the feeding system of the ruminants has a significant impact on the quality and chemical composition of milk, as well as its applicability for cheese production.

Abstract This paper describes the study of fatty acid (FA) composition and lipid quality indices of bream Abramis brama (Linnaeus, 1758) from Lake Kotokel (Western Transbaikalia). In the muscle tissues of bream sampled in 2009 and 2019, high levels of polyunsaturated fatty acids (PUFA), including essential docosahexaenoic (DHA), eicosapentaenoic (EPA), and arachidonic acids were measured. Indicators of nutritional quality based on the fatty acid composition showed that the values of the hypocholesterolemic/hypercholesterolemic (HH) ratio indices were sufficiently high. The atherogenicity (AI) and thrombogenicity (TI) indices, which are indicators for the nutritional value, were less than 1 in the studied fish. In terms of flesh-lipid quality (FLQ), bream had the highest proportion of total EPA + DHA. According to the obtained data for the composition of fatty acids in the muscle tissue of the studied fish from Lake Kotokel, the anthropogenic load on Lake Kotokel has not yet had a statistically significant effect on the fish muscle quality.
