Study on effect of combination modified on starch

Combination modified starch is a new development modified starch,which is a derivative of starch by used two or more than two modification methods.It shows more remarkable physicochemical properties than single modified starch and will greatly extend the applications of modified starch in industrial.The present review shows the study status of several typical kinds of combination modified starch such as oxidated starch,esterificated starch,etherificated starch and grafting copolymerizated starch.The study direction and potential development prospect of combination modified starch are also forecasted.
