CA 2672102

The invention pertains to a process for manufacturing paper or cardboard, wherein flour comprising a protein and starch fraction is subjected to a degradation step involving a treatment with protease and a non-starch polysaccharide (NSP) hydrolysing enzyme, after which the flour is introduced into the paper fibre matrix. It is especially preferred that the flour is rye flour, and that the NSP hydrolysing 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.

La présente invention concerne un procédé de fabrication de papier ou de carton dans lequel la farine qui contient une protéine et une fraction amidon est soumise à une étape de dégradation qui comprend un traitement avec protéase et enzyme hydrolysable de polysaccharide autre que l'amidon (NSP). La farine est ensuite introduite dans la matrice de fibre de papier. On préfère que la farine soit de la farine de seigle et que le NSP hydrolysant l'enzyme soit une hémicellulase ou une cellulase ou encore un mélange de ces dernières. L'invention concerne également une composition contenant la farine et les enzymes mentionnés ci-dessus ainsi que l'utilisation de la farine ainsi traitée comme source d'amidon.
