The invention provides a processing method for increasing vitamin D2 in edible mushrooms. The processing method comprises the following steps of performing radiation treatment on the edible mushroomsby pulse glare, wherein the spectral of pulse glare consists of UV-A of which the wavelength is 315nm-400nm, UV-B of which the wavelength is 280nm-315nm and UV-C of which the wavelength is 200nm-280nm. According to the processing method disclosed by the invention, the pulse glare treatment is adopted, so that the situation that ergosterol in the edible mushrooms is converted into vitamin D2 can bequickly promoted, and the effect of the processing method is far better than that of ultraviolet radiation; and before the pulse glare treatment is performed, the edible mushrooms are cut into slices, so that the conversion rate of the ergosterol can be obviously increased, and the browning reaction degree of fruiting bodies cannot be increased.

The invention discloses cordyceps sinensis health-care edible oil, which is mainly characterized by adding the active ingredients of cordyceps sinensis to the edible oil. The product not only has the functions of the traditional edible oil, but also has various active ingredients contained in cordyceps sinensis, such as polysaccharides, mannitol, ergosterol, nucleoside, etc, has the health-care effects of improving immunity, protecting hepatic and nephridial tissues, resisting inflammation, resisting tumors, resisting pathogenic microorganisms, resisting fatigue, delaying aging, nourishing kidney and deficiency, nourishing yin and tonifying yang, moistening lung to relieve asthma, maintaining beauty, preventing arrhythmia, coronary heart disease and angina, etc and can promote the appetite, thus achieving the effects of health care and seasoning.

The invention discloses a solid fermentation tank as well as a method for preparing red kojic rice by using the solid fermentation tank and a product prepared by the method, and belongs to the technical field of biological fermentation. The solid fermentation tank comprises a horizontal fermentation bucket, a temperature detecting opening, a humidity detecting opening, a pressure detecting opening, an inoculation opening, a sampling opening, a feeding hole, sight glass, an inlet pipe, an outlet pipe, a balance plate, a rolling bracket, a material baffle and an outside-bucket jacket. The method is used for preparing healthy nutritional red kojic rice by using the solid fermentation tank by the following steps: soaking materials; washing the materials; steaming the materials; cooling; separating; inoculating; mixing; keeping the temperature; keeping the humidity; fermenting; harvesting; and drying and the like. By virtue of the design of the invention, the environmental protection property, economic efficiency and stability of the solid fermentation tank as well as the homogeneity of the same batch of fermentation products are improved; the solid fermentation tank is applied to the preparation method; the preparation condition is optimized; the contents of red rice protein, red rice polysaccharide, ergosterol and amino acid in the prepared red kojic rice are respectively not lower than 3.0%, 2.0%, 1.0% and 1.0%; the limit amount of citrinin is not higher than 0.01mg / kg and the limit amount of monacolin K is not higher than 0.01%.

An oil or powder of ganodema spore is disclosed. Its quality control method features that the efficient liquid-phase chromatographic method and the thin-layer scanning chromatography method are used to measure the content of ergosterol in the product.
