2-O-α-D-Glucopyranosyl-L-ascrobic acid is crystallizable in its supersaturated solution. Crystalline 2-O-α-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, crystalline 2-O-α-D-glucopyranosyl-L-ascorbic acid is handleable with an ease, and superiorly high in stability and physiological activities. Thus, crystalline 2-O-α-D-glucopyranosy-L-acorbic acid is favorably useful in vitamin C-enriching agents, foodstuffs, pharmaceuticals and cosmetics.  
                            2-O-α-D-Glucopyranosyl-L-ascrobic acid 可在过饱和溶液中结晶。结晶的 2-O-α-
D-吡喃葡萄糖基-L-
抗坏血酸基本上不吸湿、可自由流动、不潮解、不固结、不具有直接还原活性,但很容易溶于
水。正因为如此,结晶的 2-O-α-D-Glucopyranosyl-L-ascorbic acid 容易处理,而且稳定性和生理活性极高。因此,结晶的 2-O-α-
D-吡喃葡萄糖基-L-
抗坏血酸可用于富含
