| 摘 要： | 甜菊糖是一种非营养性天然高倍甜味剂,其中的多种成分具有生物活性.对甜菊糖中大量存在的甜菊苷进行改性可以去除其后苦涩味并可以获得多种具有生物活性的衍生物.本文主要综述了各种糖基转移酶催化转化甜菊苷及其它衍生物的过程和产物,尤其是酶催化改性甜菊苷的区域选择性及其对其甜味特性的影响；着重分析了环糊精葡萄糖基转移酶的催化转化机理及其各种催化活性之间的竞争和关联；并对甜菊糖的代谢、毒理以及生物活性等进行了简单评述.

| Abstract: | Steviol glucoside is a natural non-calorie sweetener with some biological activities.Stevioside is the main substance in the steviol glucosides with a bitter aftertaste.Biotransformation of stevioside may get rid of its bitter taste and obtain many new bioactive derivatives.In this article,the enzymatic transglycosylation and the glycosylated products of stevioside or its analogues were discussed,especially on the regioselectivity of enzymatic transglycosylation and sweetness induced characteristics.The cat... |
