Resumo

The content of total lipids and fatty acids in tissues and body segments of adult Antarctic krill caught in three regions of the Atlantic sector of Antarctica, differing in environmental conditions, was studied. Significant differences in terms of lipid and fatty acid status of the Antarctic krill tissues and body segments in studied regions were shown. Analysis of the main metabolic indices of the E. superba lipids quality testifies to its high nutritional value, including due to the high unsaturation of its lipids, favorable ratios of physiologically significant and essential fatty acids for human health, which can be considered as a distinctive biochemical characteristic of this species. The results of the study can be used to form a scientifically based approach to further technological processing of raw krill and for the targeted extraction of certain substances and components of a lipid nature.
