The present invention provides an anti-oxidant composition comprising a cyclic compound having formula I or a derivative thereof, wherein Rand Rare indepednetly selected from &#x2014;OH, &#x2550;O, wherein Ris a substituent comprising an &#x2014;OH group; and wherein Rand Rare other than H; with the proviso that the compound is other than ascorbic acid.

Anti-oxidant

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.

Use of &agr;-1,4-glucan lyase for preparation of 1,5-D-hydrofructose

A method of preparing 1,5-D-anhydrofructose in large quantities includes treating &agr;-1,4-glucan with a substantially pure &agr;-1,4-glucan lyase, which has been isolated from algae alone, wherein 1,5-D-anhydrofructose is produced directly from the &agr;-1,4-glucan.
