Study on preparation and properties of potato hydroxypropyl starch

Cai Hua

Abstract

The properties and the optimum conditions for the preparation of potato hydroxypropyl starch were examined in this article,emphasizing on the effect of Na2SO4,propylene oxide,temperature,time on the molar substitution.The results indicated that the paste transparence,expansion degree and freeze-thaw stability of the resulting paste were improved,while its gelatinizetion temperature decrease gradually.
