rebaudioside/ジャガイモ

Rebaudioside D is a sweetener from Stevia rebaudiana with superior sweetness and organoleptic properties, but its production is limited by its minute abundance in S. rebaudiana leaves. In this study, we established a multi-enzyme reaction system with S. rebaudiana UDP-glycosyltransferases UGT76G1,

Steviol glycosides from Stevia rebaudiana leaves are used in stevia-based sweeteners for their intense sweetness and low calories. Rebaudioside D is present in leaves in minute quantities (∼0.4-0.5% w/w total dry weight), but it is ∼350 times sweeter than sucrose, and sweeter than the more abundant
