Abstract (en)

[origin: WO0031145A1] The viscosity of starch and other carbohydrates can be lowered inexpensively, rapidly and without residual streams by treatment with hydrogen peroxide and a catalyst, in particular an organic acid or acid anhydride. After carbohydrate, hydrogen peroxide and catalyst have been brought together, the material is, if necessary, pre-dried at a temperature below 60 DEG C and the dried material is then treated at a temperature of 80 - 140 DEG C. The lowered viscosity is stable.
