Problems solved by technology

For example, Chinese patent 97123371.3 discloses a kind of ganoderma lucidum nutrient powder prepared as raw material with corn flour, potato flour and soybean flour. This method has the following defects: 1. the powder culture medium raw material with a water content of 40% is easily extruded into Block, air permeability is extremely poor, Ganoderma lucidum is an aerobic fungus, which is not conducive to the growth of its mycelium; ②The medium is squeezed into blocks, and it is difficult for the liquid bacteria to penetrate into all parts of the medium during inoculation, and the growth of Ganoderma lucidum mycelium is slow; ③Use 0.1mpa for 40 minutes to sterilize, there may still be a large number of miscellaneous bacteria in the culture medium, and the survival rate of Ganoderma lucidum is low (the success rate is only 60-70% after repeated tests), and large-scale industrial production cannot be carried out

Embodiment 1

[0019] Weigh 10Kg of the mixture of corn and wheat grains with a particle size of 2:3 and a particle size of 2-3mm, so that the water content is 40%, and put them into polypropylene plastic bags with a width of 50-70mm, each bag contains 0.8Kg, 0.15Mpa, and Bacteria for 60 minutes; when the temperature of the material drops to 30°C, add 25ml of 10-day-old liquid Ganoderma lucidum to each bag. Dry at ℃, crush, and pass through 80 mesh sieve to obtain 9.04Kg. The color of the product is light yellow, and the taste has a unique fungal aroma. The nutritional ingredients are 12% of total sugar, 7% of reducing sugar, 1.8% of fat, and 9% of protein. %.

Embodiment 2

[0021] Take a mixture of corn and wheat grains with a ratio of 1:1 and a particle size of 2-3mm, so that the water content is 40%, and put them into glass bottles respectively, 0.8Kg in each bottle, and sterilize at 0.15Mpa for 60 minutes. When the temperature reaches 30°C, add 25ml of liquid bacteria, and after 19 days of constant temperature and dark culture at 25-28°C, take out the solid fermentation product from the bottle, dry it at 70°C, mix, puff, and crush it through a 200-mesh sieve. Obtained 8.85Kg this powder is light yellow, and taste has a kind of peculiar bacterium fragrance. Its nutrients are 11% of total sugar, 6% of reducing sugar, 2.2% of fat and 10% of protein.

Embodiment 3

[0023] Take corn and wheat grains with a particle size of 2-3mm in a ratio of 1:1, mix them, add water to make the water content 35-38%, put them into polypropylene plastic bags, 0.8Kg per bag, 0.15Mpa, and sterilize for 90 minutes , add 40ml of Ganoderma lucidum liquid strain, after 15 days of constant temperature cultivation at 25-28°C, dig out the solid fermentation product from the bag, dry at 70°C, expand, crush, pass through 80 mesh sieve, and obtain 9.07Kg of Ganoderma lucidum powder , the powder is light yellow in color and has a unique fungal aroma in taste, and its nutritional content is 12% of total sugar, 7% of reducing sugar, 2.2% of fat and 9.5% of protein.

Abstract

The invention provides a production method for Ganoderma Lucidum powder, which includes steps of: selecting corn and wheat with high quality according to weight ratio of 1 to 1-1.5, respectively rinsing, extruding to granule with diameter of 2-3 mm, mixing, adding water until water content reach 40%, filling in polypropylene plastic bag, sterilizing for 60-90 minutes at 0.15MPa, grafting liquid Ganoderma Lucidum strain after sterilization, culturing in shade for 15-20 days at 25-28 DEG C, digging out cultured fermentation product, drying at 70-80 DEG C, crushing, and sieving with screen of 80-200 meshes to obtain the Ganoderma Lucidum powder. The invention uses crushed raw grain as culture medium to graft liquid strain, which has fast strain growth speed, high fungus bag survival rate and good permeability, and is benificial to mycelium growth. The invention totally uses solid fermentation Ganoderma Lucidum mycelium and whole metabolite, the obtained product has rich nutrition and good taste, the Ganoderma Lucidum powder has wide raw material source and low price, and can be popular nutrition foodstuff.

Description

technical field [0001] The invention relates to a method for preparing a food composition by using fungi. Specifically, corn and wheat crushed particles are used as raw materials, ganoderma lucidum is used as a strain, and a solid-state fermentation method is adopted to produce ganoderma food with health care functions. Background technique [0002] Ganoderma lucidum is a herbal medicine in traditional Chinese medicine. It is a fungus with both medicinal and edible effects. Modern science has proved that Ganoderma lucidum has immune regulation, improves the body's resistance to hypoxia, anti-aging, anti-free radicals, and lowers blood pressure. [0003] In recent years, many health foods made from Ganoderma lucidum mycelium obtained by solid-state fermentation have also appeared on the domestic and foreign markets. For example, Chinese patent 97123371.3 discloses a kind of ganoderma lucidum nutrient powder prepared as raw material with corn flour, potato flour and soybean fl...
