摘要：

1/1 summary â € œmethod for the production of highly digestible hydrolyzed keratinous material, and use of a highly digestible hydrolyzed keratinous material â € “the method of the invention comprises the production of highly digestible hydrolyzed keratinous material comprising the steps of (i) partially hydrolyzing the heat and pressure keratinous material and (ii) optionally drying the resulting partially hydrolyzed material comprising at least partially insoluble material and (iii) subjecting the partially hydrolyzed and optionally dried keratinous material to an acid or base chemical hydrolysis step to obtain a highly digestible hydrolyzed material, and (iv) purifying the highly digestible material. The invention further provides highly digestible keratinous material with an amino acid composition reflecting the amino acid composition of the raw material, wherein the amount of decarboxylated amino acids is less than 500 ppm. preferably all highly digestible material has a molecular weight of less than 10,000 daltons, and preferably more than 95% by weight of highly digestible keratinous material has a molecular weight of less than 5,000 daltons.1 / 1 resumo “mã‰todo para a produã‡ãƒo de material queratinoso hidrolisado altamente digerã�vel, e, uso de um material queratinoso hidrolisado altamente digerã�vel â€� o mã©todo da invenã§ã£o compreende a produã§ã£o de material queratinoso hidrolisado altamente digerã­vel compreendendo as etapas de (i) parcialmente hidrolisar o material queratinoso com calor e pressã£o e (ii) secar opcionalmente o material parcialmente hidrolisado resultante compreendendo um material pelo menos parcialmente insolãºvel e (iii) submeter o material queratinoso parcialmente hidrolisado e opcionalmente seco a uma etapa de hidrã³lise quã­mica com ã¡cido ou base para obter um material hidrolisado altamente digerã­vel, e (iv) purificar o material altamente digerã­vel. a invenã§ã£o proporciona ainda material queratinoso altamente digerã­vel com
