Abstract

The present invention relates to a method for producing collagen peptides from bones, comprising the following steps: a) providing bones of vertebrates; b) mechanically crushing the bones to a particle size of less than 1 000 μm, preferably less than 500 pm, more preferably less than 300 μm, at a temperature of less than 70° C. during the crushing; c) heating the crushed bones in an aqueous suspension to a temperature of above 100° C., preferably above 120° C., more preferably above 130° C., for a period of from 1 to 30 min, preferably 2 to 10 min, more preferably 4 to 8 min; d) adding one or more proteases to the suspension in order to obtain an aqueous solution of collagen peptides; and e) separating off the aqueous solution of collagen peptides from the crushed bones, wherein the method does not comprise maceration of the bones with an acid or liming of the bones with a base, and wherein the bones provided in step a) have not undergone maceration or liming. The invention further relates to collagen peptides produced by this method.
