preparation example Construction

[0023] In a first aspect, the present invention provides a vitamin D-rich 2 The preparation method of the mushroom powder of the present invention comprises: (1) performing ultraviolet light irradiation treatment after mushroom raw material is sliced, and described ultraviolet light irradiation is combined by the UVB irradiation of 280-315nm and the UVC irradiation of 200-280nm, and the ultraviolet light irradiation During the process, the ambient temperature is 20-55° C., the relative humidity of the environment is 50-85%, and the moisture content of the mushroom raw material is not less than 20%; (2) drying the mushroom raw material obtained in step (1) under nitrogen-filled conditions; (3) Pulverizing the mushroom raw material obtained in step (2).

[0024] In the present invention, the mushroom raw material can be one or more of Agaricus bisporus, shiitake mushroom or other mushrooms, and the mushroom raw material needs to be refrigerated and stored in time within 2 days a...

Embodiment 1

[0035] (1) Slicing: the Agaricus bisporus harvested is cleaned after removing foreign matter in the culture medium to obtain the Agaricus bisporus raw material, and the 10kg Agaricus bisporus raw material is taken and cut into thin 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 The UVB irradiates both sides of Agaricus bisporus raw material slices for 180min, and then adopts a wavelength of 200nm and an irradiation dose of 80mJ / cm 2 The UVC irradiates both sides of Agaricus bisporus raw material thin slices for 30 minutes. During the irradiation process, the ambient temperature is 20°C, the relative humidity of the environment is 50%, and the moisture content of Agaricus bisporus raw material is 20%;

[0037] (3) Drying the Agaricus bisporus raw material irradiated by the ultraviolet light in a hot air circulation drying oven under the condition of nitrogen filling, and the drying temp...

Embodiment 2

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

[0041] (2) Ultraviolet light irradiation: the wavelength is 300nm, and the irradiation dose is 4J / cm 2 The UVB irradiates both sides of Agaricus bisporus raw material slices for 100min, and then adopts a wavelength of 240nm and an irradiation dose of 100mJ / cm 2 The UVC is used to irradiate the bisporus raw material slices for 25 minutes on both sides. During the irradiation process, the ambient temperature is 35°C, the relative humidity of the environment is 70%, and the moisture content of the bisporus raw material is 30%;

[0042] (3) Drying the Agaricus bisporus raw material irradiated by the ultraviolet light in a hot air circulation drying oven under a nitrogen-filled condition, and the drying temperature is...

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...
