Patent number: 6346276Abstract: 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.Type: GrantFiled: April 24, 2000Date of Patent: February 12, 2002Assignee: Asahi Kasei Kabushiki KaishaInventors: Masatoshi Tanouchi, Satoshi Tsuchiya, Haruo Fukuhara, Hitoshi Nagasaki
