    • Disclosed are a method and process for preparing a hydroxyalkyl starch. In accordance with the disclosed invention, the starch is treated with an enzyme under conditions to increase the susceptibility of the starch to hydroxyalkylation by a hydroxyalkylating agent. After the starch is so treated, the starch is hydroxyalkylated with a hydroxyalkylating agent. The hydroxyalkylation reaction can proceed to provide a starch having an MS greater than about 0.2, while still remaining in granular form in the aqueous suspension. The method of the invention thus provides a granular starch having a higher MS than is otherwise attainable via a reaction in aqueous media.
    • 公开了制备羟烷基淀粉的方法和方法。 根据所公开的发明,淀粉用酶处理,以增加淀粉对羟烷基化剂的羟烷基化的敏感性。 淀粉经过如此处理后,淀粉用羟烷基化剂进行羟烷基化。 羟基烷基化反应可以进行以提供MS大于约0.2的淀粉,同时仍然以水性悬浮液的形式存在。 因此,本发明的方法提供了一种具有比通过水性介质中的反应可获得的MS更高的颗粒淀粉。
