| Abstract: | The hydraxypropyl tapioca starch was prepared through reaction of tapioca starch with 1,2-epoxypropane using fatty alcohol polyoxyethylene ether(AEO)as a improver by wet process under common temperature.The factors afecting the degree of substitution were studied.On the basis of orthogonal test,optimum experiment conditions for hydroxypropylation were obtained. |
