  • Highly efficient method for synthesizing difructose anhydride III
    Patent number: 10351888
    Abstract: The invention discloses a high-efficiency synthesis method of difructose anhydride III. The method comprises the following steps: firstly converting sucrose into inulin by using inulosucrase without separating polysaccharide, and then converting inulin by using inulin fructotransferase to synthesize the functional disaccharide difructose anhydride III. The method has the advantages of simple process and high efficiency, and a conversion rate of synthesizing inulin into difructose anhydride III can reach 40%-54%. In order to obtain purer difructose anhydride III, yeast is utilized to remove small molecule monosaccharides in a reaction solution, and the finally obtained purer difructose anhydride III can be easily separated and purified. Thus, the method has broad market application prospects.
