Physicochemical properties modifications and applications
Chemical modification of starch involves the introduction of functional groups to the starch molecule without affecting the morphology or granule size distribution. Cationization modifies the dielectric properties of granules depending on their substitution degree reducing the paste temperature and increasing its viscosity.
