An oxidation inhibitor containing, as an active ingredient, an aminocarbonyl compound having a structure resulting from binding of an amino group of a compound having sphingoid base structure and a carbonyl group of a carbonyl compound. The oxidation inhibitor has high oxidation inhibitory effects, and inhibits oxidation of fats and oils, in particular, fats and oils containing a large proportion of polyunsaturated fatty acids to prevent deterioration due to oxidation of fats and oils.

Oxidation inhibitor, and food and drink containing fats and oils using same

A feed is disclosure includes docosahexaenoic acid and/or conjugated docosahexaenoic acid. This feed is used for farming fish such as steelheads.

Feeds containing docosahexaenoic acid and/or conjugated docosahexaenoic acid, and a method for farming fishes by using such feeds

A method of stabilizing .omega.-3 unsaturated fatty acid compounds comprising dispersing one or more compounds selected from a group consisting of an .omega.-3 unsaturated fatty acid, its derivative and an oil and fat containing the .omega.-3 unsaturated fatty acid or the derivative in an aqueous solution, is presented. .omega.-3 Unsaturated fatty acids such as DHA and EPA which have been regarded as unstable can be kept under stable conditions.
