POSSIBILITIES TO PRODUCE PORK MEAT AND PORK MEAT PRODUCTS WITH INCREASED CONTENT OF N-3 POLYUNSATURATED FATTY ACIDS

Abstract
In the paper, the health benefits of polyunsaturated fatty acids from the n-3 family were characterized and the possibilities were evaluated to increase their level in pork meat and meat products. The most frequent method used to increase the content of n-3 polyunsaturated fatty acids in pork meat is to supplement animal feed with linseed, linseed oil, fish oil, as well as algae preparations. As for meat products, this target can be achieved through: 1) the application of meat from pigs fed feed supplemented with components that are the source of n-3 PUFA; 2) replacing some quantity of animal fat, added during the production process, with vegetable or fish oil. However, the increased content of n-3 polyunsaturated fatty acids in pork meat and meat products, considered advantageous from a nutritional point of view, can lead to numbers of disadvantageous changes in the sensory quality and stability of a product. Among other things, this results from the susceptibility of polyunsaturated fatty acids to oxidation processes. Therefore, it is essentially significant to determine the optimal level of enrichment, as well as the application of antioxidants, particularly the natural ones.
