Abstract
A method of preparing the sugar 1,5-D-anhydrofructose is described. The method comprises treating an &agr;-1,4-glucan with an &agr;-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 &agr;-1,4-links, the &agr;-1,4-glucan lyase is used in conjunction with a suitable reagent that can break the other links.
