FLOUR-BASED PRODUCT, ITS PREPARATION AND USE

摘要

The invention pertains to a process for manufacturing paper or cardboard, wherein flour including a protein and starch fraction is subjected to a degradation step involving a treatment with protease and a non-starch polysaccharide (NSP) hydrolyzing enzyme, after which the flour is introduced into the paper fiber matrix. It is especially preferred that the flour is rye flour, and that the NSP hydrolyzing enzyme is a hemi-cellulase or a cellulase, or a combination thereof. The invention also pertains to a composition containing flour and the aforementioned enzymes; and to the use of flour thus treated as a source of starch.
