Summary: | To provide novel preparation methods of steviol glycosides, particularly minor steviol glycosides such as Reb J and Reb N, that can yield products with better and more consistent taste profiles.SOLUTION: The present disclosure relates to production of steviol glycosides rebaudioside J ("Reb J") and rebaudioside N ("Reb N") through the use of rebaudioside A ("Reb A") as a substrate, and a biosynthetic pathway involving various 1,2 RhaT-rhamnosyltransferases. Some embodiments include a method of preparing Reb J from Reb A, as well as preparation of Reb N from Reb A through an intermediate of Reb J. In some embodiments, the present disclosure provides a method of preparing Reb N from Reb I, as well as preparation of Reb N from Reb A through an intermediate of Reb I.SELECTED DRAWING: Figure 3A
【課題】より良好でより一貫した味覚プロファイルを有する生成物を得ることができるステビオール配糖体、特にRebJ及びRebNなどの微量のステビオール配糖体の新規調製方法を提供する。【解決手段】レバウジオシドA(「RebA」)を基質として使用することによるステビオール配糖体であるレバウジオシドJ(「RebJ」)及びレバウジオシドN(「RebN」)の製造、並びに様々な1,2RhaT-ラムノシルトランスフェラーゼを含む生合成経路に関する。いくつかの実施形態では、RebAからRebJを調製する方法と並んで、RebJの中間体によるRebAからRebNの調製を包含する。いくつかの実施形態では、RebIからRebNを調製する方法と並んで、RebIの中間体によるRebAからRebNの調製を提供する。【選択図】図3A |
