Abstract:
A process for producing water-insoluble substances derived from fishes and shellfishes, which comprises the steps of:(a) treating portions of fishes and shellfishes containing said substances with a proteolytic enzyme under stirring to obtain an oil-in-water (O/W) type emulsified composition comprising, (i) water-soluble components which comprise water-soluble amino-acids, oligoproteins having a molecular weight of not greater than 30,000, vitamins and water-soluble minerals, and (ii) water-insoluble components, as solid matter, comprising oils and fats containing water-insoluble unsaturated fatty acids and proteins having a molecular weight of 20,000 to 100,000, wherein at least 50% of all the proteins in said emulsified composition have a molecular weight of 20,000 to 100,000; (b) separating said emulsified composition into solid and liquid phases to obtain a solid composition; and (c) extracting said solid composition with an organic solvent.
