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

Example Embodiment

[0018] Example 1

[0019] Weigh 10Kg of a mixture of 2-3mm corn and wheat granules in a ratio of 2:3, with a water content of 40%, and put them into polypropylene plastic bags with a width of 50-70mm, each bag containing 0.8Kg, 0.15Mpa, and sterilization. Bacteria for 60 minutes; when the temperature of the material drops to 30 ° C, each bag is connected to 25 ml of 10-day-old liquid Ganoderma lucidum strains, and after culturing at a constant temperature of 25-28 ° C for 18 days, the solid fermentation product is taken out of the bag and placed at 80 °C. ℃ drying, pulverizing, passing through a 80-mesh sieve to obtain 9.04Kg, the color of the product is light yellow, the taste has a unique fungus fragrance, and the nutrients are 12% of total sugar, 7% of reducing sugar, 1.8% of fat, and 9 of protein. %.

Example Embodiment

[0020] Example 2

[0021] Take a mixture of corn and wheat particles 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, each bottle is 0.8Kg, sterilized at 0.15Mpa for 60 minutes, and wait for the temperature of the material to drop. When the temperature reaches 30°C, 25ml of liquid strains are inserted, and after culturing at a constant temperature of 25-28°C for 19 days in the dark, the solid fermentation product is taken out from the bottle, dried at 70°C, mixed, puffed, and pulverized through a 200-mesh sieve. 8.85Kg of the powder was light yellow and had a unique fungus fragrance. Its nutritional components are 11% of total sugar, 6% of reducing sugar, 2.2% of fat, and 10% of protein.

Example Embodiment

[0022] Example 3

[0023] Take corn and wheat particles 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 in polypropylene plastic bags, 0.8Kg per bag, 0.15Mpa, sterilize for 90 minutes , insert 40ml of Ganoderma lucidum liquid strain, after 15 days of constant temperature cultivation at 25-28°C, the solid fermentation product is dug out from the bag, dried at 70°C, puffed, pulverized, and passed through an 80-mesh sieve to obtain 9.07Kg of Ganoderma lucidum powder. , The color of the powder is light yellow, the taste has a unique fungus fragrance, and its nutrients are 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...
