Title
(EN) ENZYMATIC STARCH SACCHARIFICATION INCLUDING A MEMBRANE SEPARATION STEP
(FR) SACCHARIFICATION ENZYMATIQUE D'AMIDON, COMPORTANT UNE PHASE DE SEPARATION PAR MEMBRANE
Abstract
(EN) The present invention relates to a method for the production of saccharide preparations, i.e., syrups, by saccharifying a liquefied starch solution, which method comprises a saccharification step during which step one or more enzymatic saccharification stages take place, and the subsequent steps of one or more high temperature membrane separation steps, and re-circulation of the saccharification enzyme, in which method the membrane separation steps are carried out as an integral part of the saccharification step. In another specific aspect, the invention provides a method of producing a saccharide preparation, which method comprises an enzymatic saccharification step, and the subsequent steps of one or more high temperature membrane separation steps and re-circulation of the saccharification enzyme.
(FR) L'invention concerne un procédé de production de préparations saccharides, notamment de sirops, qui consiste à saccharifier une solution d'amidon liquéfiée. Ledit procédé consiste en une étape de saccharification à une ou plusieurs phases de saccharification enzymatique, en une ou plusieurs étapes de séparation par membrane à haute température et en la remise en circulation de l'enzyme de saccharification, les étapes de séparation par membrane faisant partie intégrante de l'étape de saccharification. Dans un autre aspect spécifique, l'invention porte sur un procédé de production d'une préparation saccharide, qui consiste en une étape de saccharification enzymatique, en une ou plusieurs étapes de séparation par membrane à haute température et en une étape de remise en circulation de l'enzyme de saccharification.
