Document Type and Number:
WIPO Patent Application WO/2012/033218
Kind Code:
A1
Abstract:
The objective of the present invention is to provide novel 2-O-α-D-glucosyl-L-ascorbic acid crystals, a method for producing the novel 2-O-α-D-glucosyl-L-ascorbic acid crystals, and use of the novel 2-O-α-D-glucosyl-L-ascorbic acid crystals. The objective is achieved by providing hydrous crystals of 2-O-α-D-glucosyl-L-ascorbic acid, a powder containing hydrous crystals of 2-O-α-D-glucosyl-L-ascorbic acid, a method for producing the hydrous crystals of 2-O-α-D-glucosyl-L-ascorbic acid, a method for producing the powder containing hydrous crystals of 2-O-α-D-glucosyl-L-ascorbic acid, a use of the hydrous crystals of 2-O-α-D-glucosyl-L-ascorbic acid, and a use of the powder containing hydrous crystals of 2-O-α-D-glucosyl-L-ascorbic acid.
