Title
(EN) IMPROVED FIBER-WASHING IN CORN WET-MILLING
(FR) LAVAGE DE FIBRES AMÉLIORÉ DANS LE BROYAGE PAR VOIE HUMIDE DE MAÏS
Abstract
(EN) A method for increasing starch yield and/or gluten yield from corn kernels in a wet milling process, comprising contacting a fiber rich fraction of ground kernels, with an effective amount of SO2, and an effective amount of one or more hydrolytic enzymes, wherein at least one of said hydrolytic enzymes is selected from xylanase and/or cellulase enzymes, during a fiber-washing step.
(FR) Un procédé permettant d'augmenter le rendement en amidon et/ou le rendement en gluten de grains de maïs dans un procédé de broyage par voie humide, consistant à mettre en contact une fraction riche en fibres de grains broyés, avec une quantité efficace de SO2, et une quantité efficace d'une ou de plusieurs enzymes hydrolytiques, au moins l'une desdites enzymes hydrolytiques étant choisie parmi les enzymes xylanase et/ou cellulase, pendant une étape de lavage de fibres.
