Based on this relationship, we can change the Tg of starch by changing its molecular weight to meet the pratical needs.The DSC technique is used to estimate the consistence character of starch with different additives. The glass transition behavious of starch blended with water and Xanthan gum are examined respectively. An expirical expression is obtained for the Tg of starch blendee with additives according to the blending model of polymers and verified with the experimental results. This expression can be used as a base to predict the Tg of starch blended with Xanthan gum.
