Title:
MUSHROOM POWDER RICH IN VITAMIN D2, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/119162
Kind Code:
A1
Abstract:
A mushroom powder rich in vitamin D2, the preparation method therefor comprising: slicing a mushroom raw material, and performing ultraviolet irradiation treatment in an environment with temperature of 20-55°C and relative humidity of 50-85%, the ultraviolet light irradiation being a combination of 280-315 nm UVB irradiation and 200-280 nm UVC irradiation, and the water content of the mushroom raw material being not less than 20%; drying the ultraviolet-irradiated mushroom raw material under nitrogen-filled conditions; and crushing the dried mushroom raw material. The conversion rate of ergosterol into the vitamin D2 is improved by controlling the wavelength, temperature and humidity conditions during the ultraviolet irradiation treatment, and a nitrogen-protected drying method is employed to prevent the vitamin D2 from forming isomer impurities or from being degraded and lost, thereby improving the quality of a mushroom powder product.
