meat, lipids, trans fatty acids, analysis, chromatography


In this study, we have focussed on the fatty acid composition of the meat of various animals raised in the Republic of Kazakhstan. We have analyzed pasture horse meat, stall horse meat, lamb, beef, and pork meat. Samples from four carcass muscles (back, hip, rib, and neck) were tested. Comparative analysis of the content of trans isomers of fatty acids (TFA) was performed. The analysis of the obtained samples showed that the TFA content is significantly (p <0.05) different in different parts of the carcasses of all animals. Their highest content was observed in the mutton sample, which reached 79.56-82.04%. The beef was next after mutton (6.20-9.64%). Less than in mutton and beef, but more than in pork and TFAs were contained in stall horse meat (2.75-5.52%). Of the two types of horse meat, there was less TFA in horse meat of pasture content (1.85-3.46%). Compared to all studied samples, the lowest level of trans fatty acids was in pork (0.91-1.39%). In horse meat of both types, TFAs were present in trans-9-C16: 1. More types of TFA were found in the meat of other animals: in mutton (trans-9-C14: 1; trans-9-C16: 1; trans-9-C18: 1; trans-11 C18: 1; trans-9-trans- 12-C18: 2), in beef (trans-9-C16: 1; trans-9-C18: 1; trans-11-C18: 1; trans-9-trans-12-C18: 2), in pork (trans-9-C16: 1). In addition to TFA, an analysis was made of the ratio of omega-6 and omega-3 (ω-6: ω-3). Considering that the lower the ratio of ω-6: ω-3 in fat, the healthier it is for the human body, the most optimal among the studied samples in terms of the ratio of ω-6: ω-3 fatty acids was mutton (1.83-2.35) and horse meat of stall keeping (1.76-6.53). The most unfavourable ratios were in the pork samples (17.46-35.69). The ratio ω-6: ω-3 in other animals was within the following limits: beef (5.35-9.13), horse meat of pasture content (7.08-10.50).
