An aqueous solution of dehydro-L-ascorbic acid (DHA) was heated for 1hr at 100℃, and five degraded products, including L-ascorbic acid (AsA), 3-hydroxy-2-pyrone, and 2-furoic acid, were detected. 3-Hydroxy-2-pyrone and 2-furoic acid accounted for about 11% and 0.8% yield of DHA used, respectively. 3, 4-Endiol form of 2, 3-diketo-L-gulono-δ-lactone (3, 4-End DKGL) was formed from DHA under mild deoxygenated conditions in an approximate yield of 10%, and it reduced DHA to AsA. 3, 4-End DKGL was unstable and suppressed the peroxidation of linoleic acid. The oxidized form of 3, 4-End DKGL may catalyse browning reaction.
