ABSTRACT:
2-O-.alpha.-D-Glucopyranosyl-L-ascrobic acid is crystallizable in its supersaturated solution. Crystalline 2-O-.alpha.-D-glucopyranosyl-L-ascorbic acid is substantially nonhygroscopic, free flowing, free of deliquescence, consolidation and direct reducing activity, but is readily soluble in water. Because of these characteristics, crystalline 2-O-.alpha.-D-glucopyranosyl-L-ascorbic acid is handleable with an ease, and superiorly high in stability and physiological activities. Thus, crystalline 2-O-.alpha.-D-glucopyranosyl-L-acorbic acid is favorably useful in vitamin C-enriching agents, foodstuffs, pharmaceuticals and cosmetics.
