摘要：
The present invention provides a (preferably defatted) rice bran hydrolysate composition which comprises of more than 50 wt% (on dry matter) of (poly)peptides and which has a DH (Degree of Hydrolysis) of at least 10%, preferably between 10 and 16% and more than 90%, preferably more than 95%, of the (poly) peptides has a molecular weight (MW) of more than 500 Da. According to another aspect of the invention a process to produce a (preferably defatted) rice bran hydrolysate composition (preferably having a protein content of more than 50 wt% (on dry matter) is provided which comprises - adding an aqueous liquid, preferably water, to (preferably defatted) rice bran - separating the liquid from the solid fraction to obtain a washed solid fraction - adding an enzyme or enzyme composition to a suspension of the washed solid fraction which suspension has a concentration of between 5 and 30 wt%, preferably of between 12 and 30 wt% - performing an enzyme incubation preferably at a pH between 6 and 8 - performing the enzyme incubation to an extent of hydrolysis of between a DH (Degree of Hydrolysis) of 10 and 16% - performing the enzyme incubation at a temperature of between 30 and 80 °C preferably between 45 and 65 °C and - optionally separating the liquid from the solid fraction whereby the enzyme or enzyme composition comprises an endoprotease.La présente invention concerne une composition dhydrolysat de son de riz (de préférence déshuilé) qui comprend plus de 50 % en poids (sur la base de la matière sèche) de (poly)peptides et qui a un DH (degré dhydrolyse) dau moins 10 %, de préférence compris entre 10 et 16 %, et dont plus de 90 %, de préférence plus de 95 %, des (poly)peptides ont une masse moléculaire (MW) supérieure à 500 Da. Un autre aspect de linvention concerne un procédé de production dune composition dhydrolysat de son de riz (de préférence déshuilé) (ayant de préférence une teneur en protéines supérieure à 50 % en poids (sur la base de la matière sèche)) compre
