WINTER SEASON KRILL (EUPHAUSIA-SUPERBA D) AS A SOURCE OF N-3 POLYUNSATURATED FATTY-ACIDS

Krill (Euphausia superba D.) caught in winter near South Georgia were examined as a raw, intermediate product, precipitate and by product. T he following assayes were performed: lipid composition (TLC), fatty ac id composition (GC), lipid susceptibility to oxidation, and carotenoid s content. The krill harvested in July/August was found to contain abo ut 3% of lipids. The amount of n-3 polyunsaturated fatty acids (PUFA; eicosapentaenoic and docosahexaenoic acids) in total lipids of whole k rill 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 li pid formula. Euphausia superba is a valuable source of n-3 PUFA, prima rily because of their stability in krill.
