Abstract
A method for rapidly sterilizing animal protein to give a product for use as a foodstuff is disclosed wherein animal protein is ground to bring it into a state of a viscous slurry of particles of animal protein having a mean particle size from about 0.1 millimeter to 20 millimeters, the slurry is hydrolyzed, and the hydrolyzed slurry is sterilized by heating in a thin layer at a temperature from about 120.degree. C. to about 150.degree. C. for a time between about 3 seconds and about 15 minutes.
Claims8
A method for rapidly sterilizing a protein hydrolysis product of animal offal to give a product for use as a foodstuff, which method comprises:
- (a) grinding animal offal to bring it into the state of a viscous slurry of particles of animal protein having a mean particle size from about 0.1 millimeter to 20 millimeters,
- (b) partially hydrolyzing said slurry by the addition of acid thereto to convert animal protein therein to lower molecular weight constituents, and
- (c) then heating a thin layer of said hydrolyzed slurry at a temperature from about 120.degree. C. to about 150.degree. C. for a time between about 3 seconds and about 15 minutes to sterilize said slurry without coagulation of residual protein therein.
