A process for producing water-insoluble substances derived from fishes and shellfishes, includes the treating of the waste of fishes and shellfishes containing the substances with proteolytic enzymes under stirring to obtain an oil-in-water (O/W) type emulsified composition. This composition contains water-soluble amino-acids, oligoproteins having a molecular weight of not greater than 30,000, water-soluble minerals, water-insoluble highly unsaturated fatty acids and proteins (solid matter) having a molecular weight of 20,000 to 100,000, with 50% or more of all the proteins in said emulsified composition having a molecular weight of 20,000 to 100,000. Thereafter the emulsified composition is separated into solid and liquid phases, and the obtained solid composition containing proteins with a molecular weight of 20,000 to 100,000 and fats and oils is extracted with an organic solvent.
A process for producing water-insoluble substances derived from fishes and shellfishes, which comprises the steps of:
An oil-in-water (O/W) type emulsified composition obtained by treating portions of fishes and shellfishes containing said composition of substances with a proteolytic enzyme under stirring, which comprises (i) water-soluble components comprising 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 highly unsaturated fatty acids and proteins having a molecular weight of 20,000 to 100,000, wherein at least 50% of all the proteins in the emulsified composition have a molecular weight of 20,000 to 100,000.
A solid composition comprising proteins having a molecular weight of 20,000 to 100,000 and oils and fats, obtained by separating into solid and liquid phases an oil-in-water (O/W) type emulsified composition, which is obtained by treating portions of fishes and shellfishes containing said composition with a proteolytic enzyme under stirring;
An edible composition containing at least 35% based on a dry cake of the edible composition of a phospholipid, an unsaturated fatty acid in an amount of at least 40% based on the whole fatty acids in the phospholipid, and proteolytic enzyme-treated matter of fishes and shellfishes.
