  • USE OF ALPHA-1,4-GLUCAN LYASE FOR PREPARATION OF 1,5-D-HYDROFRUCTOSE
    Publication number: 20020142403
    Abstract: A method of preparing the sugar 1,5-D-anhydrofructose is described. The method comprises treating an alpha -1,4-glucan with an alpha -1,4-glucan lyase wherein the enzyme is used in substantially pure form. In a preferred embodiment, if the glucan contains links other than and in addition to the alpha -1,4-links, the alpha -1,4-glucan lyase is used in conjunction with a suitable reagent that can break the other links.
