[Effect of storage and handling on the fatty acid composition of the Antarctic krill Euphausia superba].
Gas liquid chromatography and chromato-mass-spectrometry were used to study and compare the fatty acid composition of lipids from the Antarctic krill Euphausia superba shortly after catch and after storage for 6 months in the frozen form or thermally treated and then frozen. Fatty acid lipids were found to contain acids having a methyl group in the 2d position, and acids having an OH group in the 2d and 3d positions, which had not been reported before. The technological treatment did not produce any changes in fatty acid composition which might affect the biological value of the product under consideration.
