TRATAMIENTOS ENZIMÁTICOSENZYMES A POWERFUL TOOL IN PULP AND PAPER INDUSTRY
ENZYMATIC MODIFICACIÓN OF STARCH FOR SURFACE SIZING AND COATING
Treatment specially developed for the degradation of starch used for the coating and surface sizing of paper applied in Size-Press.
The aim of the treatment is to adjust the viscosity of the starch according to the needs and the desired properties.
The α-amylase exerts its action on the starch polymers allowing adjustment of the viscosity level of starch solution to the needs.
Since it only targets on the starch, it does not negatively affect the cellulose, as it would occur with the use of oxidative methods.
Controlling the viscosity of starch
No aggressive chemicals needed
Easy to inactivate, making the process easy to control.
FDA approval as component of articles in food contact (indirect food additives FDA 21 CFR 176.170, 176.180).
