Problems solved by technology

[0003] The present invention aims at the existing problems: the culture medium used in the cultivation process of shiitake mushrooms is mostly directly utilized in the state of raw materials, and the nutritional components are not decomposed, and the nutrients such as carbohydrates and proteins mostly exist in the form of macromolecules. The absorption and utilization rate of ingredients is low, the growth rate of shiitake mushrooms is slow, the nutritional value is low, and the cost of medium resources is wasted; the inoculated strains have not been activated, and the adaptability of the strains to the external environment is low, resulting in the survival rate of the inoculated strains Low, slow spore germination and growth

Embodiment 1

[0018] A cultivation method rich in polysaccharide shiitake mushrooms, comprising the following steps:

[0019] (1) Pretreatment: First, put the raw materials in a steamer for cooking to degrade the prepared raw materials. The temperature is 96°C, the pressure is 0.43Mpa, and the time is 51min. The mixed enzyme can promote the release of intracellular nutrients, degrade macromolecular proteins and sugars into amino acids and small molecular polysaccharides, increase the content of polysaccharides in the culture medium and the absorption and utilization of nutrients, and obtain enzymatic raw materials;

[0020] (2) Saccharification and fermentation: Add mixed bacterial agents to the enzymatic hydrolysis raw materials, mix evenly and put them in a fermenter for fermentation, which can promote the degradation of sugar components in organic matter and increase the content of polysaccharide components in the medium. The temperature is 27 °C, first Ferment for 12.5 hours under the c...

Embodiment 2

[0030] (1) Pretreatment: First, put the raw materials in a steamer for cooking to degrade the prepared raw materials. The temperature is 97°C, the pressure is 0.56Mpa, and the time is 54min. Enzymes can promote the release of intracellular nutrients, degrade macromolecular proteins and sugars into amino acids and small molecular polysaccharides, increase the content of polysaccharides in the culture medium and the absorption and utilization of nutrients, and obtain enzymatic raw materials;

[0031] (2) Saccharification and fermentation: Add mixed bacterial agents to the enzymatic hydrolysis raw materials, mix them evenly and place them in a fermenter for fermentation, which can promote the degradation of sugar components in organic matter and increase the content of polysaccharide components in the medium. The temperature is 28°C, first Ferment for 13.5 hours under the condition of vacuum degree of 67%, and then ferment for 18 hours under the condition of vacuum degree of 100%....

Abstract

The invention discloses a cultivation method of mushrooms rich in polysaccharide. The method is characterized by comprising the following steps of 1, pretreatment, wherein raw materials are firstly placed into a steamer to be stewed, and after cooling, mixed enzyme liquid is added to conduct enzymolysis; 2, diastatic fermentation, wherein a mixed bacterial agent is added into the enzymolysis raw materials, and after the mixed bacterial agent and the raw materials are uniformly mixed, the mixture is placed into a fermentation tank to be fermented; 3, culture activation, wherein the mushroom culture is put into a constant temperature box to be subjected to activation treatment; 4, inoculating, wherein the activation culture of which the mass accounts for 4%-5% of that of a culture medium is added into the culture medium, and after the activation culture and the culture medium are uniformly mixed, the mixture is bagged to be subjected to temperature varying treatment; 5, greenhouse culturing, wherein the bagged culture is placed into a greenhouse to be subjected to oxygen enrichment cultivation.

Description

technical field [0001] The invention belongs to the technical field of shiitake mushroom cultivation, and in particular relates to a cultivation method of shiitake mushrooms rich in polysaccharides. Background technique [0002] Lentinus edodes is a famous edible fungus variety in my country, known as the "Queen of Mushrooms", known as "Mountain Treasures" among the people, after analysis and determination: the protein content in every 100g of dried shiitake mushrooms is about 18g, which is higher than that of oyster mushrooms, mushrooms, Tremella and other edible fungi have a fat content of about 1.8g and a carbohydrate content of more than 50%, which is characterized by rich nutrients and high content; shiitake mushrooms contain mannitol, trehalose, fungus sugar, glucose, pentosan, etc. The polysaccharide component has the effects of improving the body's immunity, anti-oxidative aging, anti-cancer and anti-cancer, invigorating the spleen and kidney, and has high health care ...
