Preparation method of fructus lycii extract rich in 2-O-beta-D-Glucopyranosyl-L-ascorbic acid

The invention provides a preparation method of a fructus lycii extract rich in 2-O-beta-D-Glucopyranosyl-L-ascorbic acid. A yeast biological fermentation method is adopted, so that the content of the2-O-beta-D-Glucopyranosyl-L-ascorbic acid is remarkably increased. The fructus lycii extract with the...

Zusammenfassung:	The invention provides a preparation method of a fructus lycii extract rich in 2-O-beta-D-Glucopyranosyl-L-ascorbic acid. A yeast biological fermentation method is adopted, so that the content of the2-O-beta-D-Glucopyranosyl-L-ascorbic acid is remarkably increased. The fructus lycii extract with the 2-O-beta-D-Glucopyranosyl-L-ascorbic acid content of 3.0% is prepared, and the application range of the fructus lycii extract is widened, for example, the fructus lycii extract can be used for anti-glycation products, foods for diabetics and the like. The fructus lycii extract can be used as a sustained-release agent of ascorbic acid, has wide application prospects and use values in cosmetic markets, pharmaceutical industries and food preservatives, and has relatively great social benefits andeconomic values. Compared with existing fine filtration, ultrafiltration and nanofiltration membrane processes, the method has the remarkable advantages of being easy and convenient to operate, highin production efficiency, n
