ABSTRACT:
Starch is phosphorylated by an improved pollution-free process which involves forming a reagent solution of an alkali metal tripolyphosphate salt in water having 20- 36% by weight of the salt dissolved therein, forming a starch cake containing no more than 45% by weight moisture, adding 2 - 30% by weight of the tripolyphosphate salt reagent solution to the starch cake, and drying and heat-reacting the thus-impregnated starch. In this process more efficient impregnation of the starch is achieved. The impregnation is preferably effected in a centrifuge.
