Example Embodiment

[0023] In the first aspect, the present invention provides a vitamin D 2 The method for preparing mushroom powder includes: (1) slicing mushroom raw materials and then subjecting them to ultraviolet light irradiation. The ultraviolet light irradiation is a combination of 280-315nm UVB irradiation and 200-280nm UVC irradiation, and the ultraviolet light irradiation During the process, the ambient temperature is 20-55°C, the ambient relative humidity is 50-85%, and the moisture content of the mushroom raw material is not less than 20%; (2) The mushroom raw material obtained in step (1) is dried under nitrogen-filled conditions; (3) Grind the mushroom raw material obtained in step (2).

[0024] In the present invention, the mushroom raw material can be one or more of bisporus, shiitake or other mushrooms, and the mushroom raw materials need to be timely refrigerated and stored for later use within 2 days after being harvested, and the refrigerating temperature is below 15°C; The ult...

Example Embodiment

[0034] Example 1

[0035] (1) Slicing: The harvested Agaricus bisporus is cleaned after removing the foreign matter in the medium to obtain the Agaricus bisporus raw material, weighing 10kg Agaricus bisporus raw material and cutting into slices with a thickness of 0.8mm;

[0036] (2) Ultraviolet light irradiation: the wavelength is 280nm and the irradiation dose is 1.5J / cm 2 Irradiate both sides of the raw material slices of Agaricus bisporus for 180min with UVB, and then use a wavelength of 200nm and an irradiation dose of 80mJ / cm 2 UVC on both sides of the raw material slices of Agaricus bisporus for 30min, during the irradiation process, the ambient temperature is 20℃, the relative humidity of the environment is 50%, and the moisture content of the raw material of Agaricus bisporus is 20%;

[0037] (3) The raw material of Agaricus bisporus irradiated by the ultraviolet light is dried in a hot air circulating drying box under nitrogen filling conditions, and the drying temperature i...

[0040] (1) Slicing: The harvested Agaricus bisporus is cleaned after removing the foreign matter in the medium to obtain the Agaricus bisporus raw material, weighing 10 kg of Agaricus bisporus raw material and cutting into slices with a thickness of 1.2mm;

[0041] (2) Ultraviolet light irradiation: the wavelength is 300nm and the irradiation dose is 4J / cm 2 Irradiate both sides of the raw material slices of Agaricus bisporus with UVB for 100min, then use a wavelength of 240nm and an irradiation dose of 100mJ / cm 2 UVC on both sides of the raw material slices of Agaricus bisporus was irradiated on both sides for 25min. During the irradiation, the ambient temperature was 35℃, the relative humidity of the environment was 70%, and the moisture content of the raw material of Agaricus bisporus was 30%;

[0042] (3) The raw material of Agaricus bisporus irradiated by the ultraviolet light is dried in a hot air circulating drying box under nitrogen-filled conditions, and th...

Abstract

The invention relates to the field of domestic fungus processing, and discloses a mushroom powder rich in vitamin D2, and a preparation method and an application thereof. The preparation method comprises the following steps: slicing a mushroom raw material, and performing ultraviolet irradiation treatment in an environment having a temperature of 20-55 DEG C and a relative humidity of 50-85%, wherein the ultraviolet light irradiation is a combination of 280-315 nm UVB irradiation and 200-280 nm UVC irradiation, and the water content of the mushroom raw material is not less than 20%; drying theultraviolet-irradiated mushroom raw material under a nitrogen-filling condition; 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 ultraviolet irradiation treatment, and a nitrogen-protected drying process is adopted to avoid the vitamin D2 from forming isomer impurities or from being degraded and lost in order to improve the quality of the mushroom powder product.

Description

technical field [0001] The invention relates to the field of edible mushroom processing, in particular to a vitamin D-rich 2 Mushroom powder and its preparation method and application. Background technique [0002] Vitamin D is an essential fat-soluble steroid derivative for the human body. In addition to the nutritional function of regulating calcium and phosphorus metabolism, it also has the functions of anti-tumor, preventing cardiovascular disease, autoimmune disease and diabetes. Forms closely related to health are vitamin D 2 and vitamin D 3 . Vitamin D 3 It can be obtained by the isomerization of 7-dehydrocholesterol in human epidermal cells after sunlight irradiation, while vitamin D 2 The human body cannot synthesize it by itself. The incidence of children with osteoporosis, rickets and senile osteoporosis is relatively high in China. Therefore, it is necessary to seek a variety of dietary ways to supplement the body's vitamin D 2 s level. [0003] Vitamin D...
