  • Patent number: 11180788
    Abstract: The present invention discloses a method for preparing lower graft degree GSGs, and belongs to the technical field of biosynthesis of sweeteners. The method uses amylase to catalyze hydrolysis of GSGs with a high graft degree, thereby obtaining GSGs with low graft degree mainly containing GSGs with a low grafting number. The content of mono- and di-glucosyl substituents in the SGs in the product was 60% or more of the total glycosides, and the mass percent of the GSGs with a glucosyl grafting number of 3 or less was higher than 70% of the total glycosides.
