Problems solved by technology

[0004] Aiming at the problems of high molecular weight, low biological activity and high preparation cost of the polysaccharide of the fruiting body of Schizophyllum, the inventors unexpectedly found that when the polysaccharide was groping for a process that could reduce the molecular weight of the polysaccharide and enhance its biological activity, the high-energy electron Flow ionizing radiation treatment, the molecular weight of schizophyllan extracted from the treated fruiting bodies decreased significantly; in addition, the extracted schizophyllan can not only effectively improve the diversity of intestinal flora, but also promote the formation of beneficial intestinal flora. Growth, inhibits the growth of potential pathogenic bacteria in the intestinal tract, and can effectively resist weight gain, can be used as a supplementary food for natural, no side effects weight loss and regulation of intestinal flora

Embodiment 1

[0023] The fruiting body of Schizophyllum is dried and then crushed and sieved. The size of the powder of Schizophyllum is 80 meshes; the powder of Schizophyllum is put into a bag and placed in an electron current irradiation device for electron current irradiation treatment, wherein the electron current is β-ray , the absorbed dose is 50kGy, and the radiation dose rate is 10kGy / min; take the material powder irradiated by the electron current, add 40 times the amount of water to soak, make the powder fully absorb water and swell, adjust the pH value to 6.2, add compound enzyme, the amount of enzyme Add 120,000 U of papain, 50,000 U of cellulase, and 50,000 U of pectinase per kilogram of raw materials, and enzymatically hydrolyze for 3 hours at 37°C; place the enzymatic hydrolyzate in a subcritical extraction kettle for subcritical deionization For water extraction, the extraction temperature is 198°C, the pressure of the reactor is 10.2MPa, the ratio of solid to liquid is 1:12,...

Abstract

The invention provides a preparation method of activity-enhanced schizophyllum commune polysaccharide, which comprises the following steps: by taking schizophyllum commune sporocarp powder as a raw material, irradiating with limited high-energy electron flow, adding compound enzyme to carry out enzymolysis reaction, then carrying out subcritical deionized water extraction on enzymatic hydrolysate, and carrying out subsequent impurity removal treatment to obtain the schizophyllum commune polysaccharide. The molecular weight of the schizophyllum commune polysaccharide extracted by the method is remarkably reduced, so that the schizophyllum commune polysaccharide not only can effectively improve the diversity of intestinal flora, promote the growth of beneficial intestinal flora and inhibit the growth of potential pathogenic bacteria in intestinal tracts, but also can effectively resist the weight increase, and can be used as a natural auxiliary food which is free from side effects and is used for losing weight and regulating the intestinal flora.

Description

technical field [0001] The invention belongs to the technical field of edible fungus deep processing, and in particular relates to a preparation method of activity-enhanced schizophyllan and its application in weight loss and increasing beneficial intestinal flora. Background technique [0002] Schizophyllum is a large rare edible and medicinal fungus. In addition to the tough and crisp meat and strong fragrance, Schizophyllum also contains a variety of biologically active substances, such as polysaccharides, polyphenols and ergosterol. As early as the 1960s, Japanese scholars obtained Schizophyllum exopolysaccharide through mycelium submerged fermentation technology and confirmed its anti-tumor effect. Subsequently, it was found that schizophyllan also has various biological functions such as immune regulation, anticancer, antiviral and antioxidation. Before artificial domestication and cultivation were realized, people mainly obtained schizophyllan through mycelium subme...
