Abstract
Fish oil from natural salmon and trout of different habitats can differ significantly in the qualitative and quantitative composition of polyunsaturated fatty acids (PUFA). The aim of the study is to compare the composition of the investigated fish fat samples of different breeds and habitat by studying their composition by mass content of PUFA as factors of influence on the functioning of various life-support systems of the human body. The experimental results prove that salmon and trout fish oil samples have significant differences in the qualitative and quantitative composition of PUFAs. Omega-3 PUFAs predominate in salmon fat samples, their total content being 33,7%. In trout fat samples, omega-3 PUFAs account for only 13,3%. A distinctive feature of trout fat is its high content of omega-6 PUFAs and much higher content of omega-9 PUFAs. As for the influence of trout habitat, comparative analysis proves the undeniable advantage of fish oil from natural trout, where the mass fraction of Omega- 3, Omega-6 and Omega-9 acids is 13,3%, 19,9% and 56,7%, respectively (in «Aquaculture» – 8,9%, 15,9% and 47,7%, respectively). Thus, the results of comparative chromatographic analysis prove that the studied fish oil samples have a high content of triglycerides – the natural form of Omega-acids, which are the main type of energy to ensure the effective vital activity of the human body.
