Abstract

See full text

The method of the invention comprises the production of highly digestible hydrolysed keratinaceous material comprising the steps of (i) partly hydrolysing keratinaceous material with heat and pressure and (ii) optionally drying the resultant partly hydrolysed material comprising at least partly insoluble material and (iii) subjecting the optionally dried partly hydrolysed keratinaceous material to a chemical hydrolysis step with acid or base to obtain a highly digestible hydrolysed material, and (iv) purifying the highly digestible material. The invention further provides highly digestible keratinaceous material with an amino acid composition reflecting the amino acid composition of the raw material, wherein the amount of de-carboxylated amino acids is less than 500 ppm. Preferably all of the highly digestible material has a molecular weight lower than 10000 dalton, and preferably more than 95 wt % of the highly digestible keratinaceous material has a molecular weight of less than 5000 dalton.
