Embodiment 1

[0048] 1. A preparation method of mushroom edible fungus polysaccharide, comprising the steps of:

[0049] (1) Mushroom edible fungus pretreatment: take three portions of fresh Agaricus bisporus, 50g each, samples A, B and C respectively, wash with clean water and dry the surface moisture, take the stipe and cap of the edible fungus and grind them with a pulverizer Crumble into a homogenate, the particle size is about 100 mesh, add 0.1 times the quality of ultrapure water and mix to obtain a homogenate;

[0050] (2) Autolysis and enzymolysis of mushroom edible fungus: Put the homogenate in a water bath, keep sample A at 45°C for 6h, sample B at 45°C for 1.5h, and sample C at 30°C for 6h, and use Stir with a mixer at a stirring speed of 100r / min to obtain the edible fungi of autolyzed mushrooms;

[0051](3) Stop the autolysis of mushroom edible fungus: after the heat preservation is over, heat the autolyzed edible mushroom mushroom obtained in step (2) in a water bath at 100°C...

Abstract

The invention discloses edible mushroom polysaccharide, and a preparation method and application thereof, belonging to the technical field of food biology. The preparation method of the edible mushroom polysaccharide comprises the following steps: (1) pretreating edible mushrooms; (2) carrying out autolysis and enzymolysis on the edible mushrooms; (3) stopping autolysis of the edible mushrooms; and (4) extracting the edible mushroom polysaccharide to obtain crude edible mushroom polysaccharide. According to the preparation method of the edible mushroom polysaccharide, endogenous enzymes of edible mushrooms are fully used for enzymolysis of polysaccharide in the edible mushrooms, and polysaccharide hydrolase is used for degradation, so the in-vitro antioxidant activity and anti-tumor activity of the edible mushroom polysaccharide is improved.

Description

technical field [0001] The invention belongs to the field of food biotechnology, and in particular relates to a mushroom edible fungus polysaccharide and its preparation method and application. Background technique [0002] Edible mushrooms have high economic value. In recent years, the output of edible fungi in my country has been increasing year by year, and has become an important economic crop. At present, there are more than 60 kinds of edible fungi artificially cultivated in my country. The main varieties are shiitake mushroom, bisporus mushroom, enoki mushroom, xiuzhen mushroom and so on. Among them, the output of oyster mushroom, shiitake mushroom and bisporus mushroom is over one million tons. Edible mushrooms are delicious and nutritious, rich in protein, fatty acid, cellulose, mineral elements and other nutrients. In addition, edible fungi also have certain health care functions, such as edible fungus polysaccharides have anti-tumor effects, and tyrosinase in ed...
