1182-2 Abstract of Disclosure The present invention relates to a procedure for hydro- lyzing keratin, in which procedure the solid keratin in- gredient is (a) pretreated with an aqueous solution con- taining sulphite ions to form denatured keratin, and (b) hydrolyzed with the aid of a proteolytic enzyme to form keratin hydrolysate. The pretreatment is carried out at about 60 to 100 °C and it lasts about 10 minutes to 4 hours. The hydrolysate thus obtained can be treated further for use as fodder addition or to form oligopeptides for use in cosmetics.
