一种葡萄糖基甜菊糖苷的制备方法
By adding metal ions and repeatedly supplementing glycosyl acceptors during the preparation of glucosyl steviol glycosides, the reaction conditions were optimized, solving the problems of high production costs and low raw material utilization. This resulted in high conversion rates and low substrate residues, making it suitable for industrial production.

Abstract
本发明涉及食品添加剂技术领域，公开了一种葡萄糖基甜菊糖苷的制备方法，该方法包括以下制备步骤：步骤1：将糖基受体、糖基供体、酶和金属离子混合制成反应物；步骤2：向步骤1中的反应物中补加至少一次糖基受体并反应制得葡萄糖基甜菊糖苷。该方法通过添加金属离子和多次补加糖基受体显著增加了甜菊糖苷转化率、显著提高了原料利用率并显著降低底物残留量，本申请的制备方法中ST转化率可达89.0%，RA转化率可达83.7%，糖基供体残留量可达3.3%，ST残留量可达2.0%，RA残留量可达2.2%。
