| 摘 要： | 应用In-Vitro模型研究了羟丙基淀粉颗粒及其糊的消化性能，结果表明：羟丙基化能够提高淀粉颗粒的消化速度，增加消化产物；对于羟丙基淀粉糊，则随取代度增大，消化速度减慢，消化产物减少，取代度大于2．0的高取代度羟丙基淀粉，相同条件下其消化速度远远小于低取代度淀粉糊，甚至小于取代度的淀粉颗粒。

| Abstract: | The digestibilities of hydroxypropyl starch and its pastes were investigated with In_Vitro model . The results showed that the digestibility and the carbohydrate digestion products of hydro_ xypropyl starch granules increased but those of their pastes decreased with the molar substitution increasing. When the molar substitution is greater than 2.0, the hydroxypropyl starches were hydrolyzed with a slower rate than the pastes and granules of starches with low molar substitution. |
