Abstract
.alpha.-Glycosyl-L-ascorbic acid exhibiting no direct reducing activity is formed in a solution containing L-ascorbic acid and an .alpha.-glucosyl saccharide when subjected to the action of a saccharide-transferring enzyme. .alpha.-Glycosyl-L-ascorbic acid is superiorly stable, and readily hydrolyzable in vivo to exhibit the activities inherent to L-ascorbic acid. Thus, .alpha.-glycosyl-L-ascorbic acid is favorably useful as a stabilizer, quality-improving agent, antioxidant, physiologically active agent and uv-absorbent in food pharmaceutical and cosmetic industries.
