Hydrolysis product of fish protein having satiety activity, nutritional supplement and pharmaceutical composition containing the hydrolysis product, and method for producing the same.
The present invention relates to a fish protein hydrolysate containing molecules capable of exerting a satietogenic activity and of regulating food intake in humans or animals. More specifically, the protein hydrolysate according to the invention enables stimulation of the secretion of endogenous cholescystokinins (CCKs) and of endogenous glucagon-like peptide 1 (GLP1) molecules by intestinal cells and the supply of exogenous CCKs. The fish protein hydrolysate according to the invention is obtained by enzymatic hydrolysis of at least one protein source selected from the group composed of the pelagic fish species Micromesistius poutassou, Clupea harengus, Scomber scombrus, Sardina pilchardus, Trisopterus esmarki and Trachurus spp., the demersal fish species Gadus morhua, Pollachius virens, Melanogrammus aeglefinus and Coryphaenoides rupestris, and the species of fish belonging to the order Siluriformes, said enzymatic hydrolysis being carried out by means of a mixture of enzymes comprising endopeptidases derived from Bacillus amyloliquefaciens and from Bacillus licheniformis, or derived from Bacillus amyloliquefaciens, from Bacillus licheniformis and from Aspergillus oryzae.
