Abstract Krill ( Euphausia superba D.) caught in winter near South Georgia were examined as a raw, intermediate product, precipitate and by product. The following assayes were performed: lipid composition (TLC), fatty acid composition (GC), lipid susceptibility to oxidation, and carotenoids content. The krill harvested in July/August was found to contain about 3% of lipids. The amount of n‐3 polyunsaturated fatty acids (PUFA; eicosapentaenoic and docosahexaenoic acids) in total lipids of whole krill accounts for 19.0 ± 1.7% of fatty acids. There was no any lost of n‐3 PUFA during processes used to obtain the precipitate and the lipid formula. Euphausia superba is a valuable source of n‐3 PUFA, primarily because of their stability in krill.
