Patent ID: 8591971

Claim:
A method for preparing a proteinaceous product from raw protein-comprising animal matter, the method comprising: (a) providing the raw animal matter in a ground condition; (b) adding food grade oil to form an animal matter/oil suspension; (c) hydrolysing the proteins in the animal matter/oil suspension using proteolytic enzymes, where the hydrolysis is performed at a selected temperature within a range conducive for hydrolytic activity of the enzymes without denaturing the protein and for a time period sufficient to achieve a preselected degree of partial hydrolysis of the protein, to form a hydrolysate/oil suspension; (d) heating the hydrolysate/oil suspension to deactivate the proteolytic enzymes; (e) removing at least some non-digestible solids from the hydrolysate/oil suspension; (f) pasteurizing the hydrolysate/oil suspension; (g) reducing the concentration of water in the suspension; and (h) removing a portion of the oil from the suspension to form a particulate, partially hydrolysed, non-denatured proteinaceous product.
