Silver fungus is rich in nutrients and delicious in flavor, and it is an edible fungus with high nutritional value. With the rapid development of ginkgo cultivation industry, the research on the nutritional composition of ginkgo and its role in health care has been gradually deepened. Ginkgo biloba polysaccharide is an important active ingredient of ginkgo biloba, and its function is getting more and more attention.

Functional properties of ginkgo biloba polysaccharide

1. Processing characteristics in food production

Ginkgo biloba polysaccharides contain more homogeneous polysaccharides (about 70-75% of the total polysaccharides), which have the effect of increasing the viscosity of the solution and emulsification stabilization. Therefore, when applied to the processing of beverages, dairy products and cold drinks, it not only gives good processing characteristics to the food, but also reduces the use of synthetic additives and improves the nutritional value of the food.

2. Health care and medical effects

Ginkgo biloba polysaccharide composition has a diversity of components, not only the monomer is diverse, the formation of polymers after the conformation and conformation of the same diversity: a variety of polysaccharides mixed together, so that its biological activity is also diverse. Modern research has fully confirmed that ginkgo biloba polysaccharide has a variety of health care functions, which are summarized as follows:

(1) Immunomodulation, anti-tumor effects

Over the years, scientists have found that ginkgo biloba polysaccharides are involved in the regulation of various cellular life phenomena, such as the transmission and feeling of information between immune cells, activation of immune cells and enhancement of the body’s immune function. Through this participation, ginkgo biloba polysaccharide can not only play an anti-tumor role by enhancing the host immune function, but also directly kill tumor cells by directly acting on tumor cells or inducing apoptosis of tumor cells.

(2) Hypoglycemic and hypolipidemic effects

It has been shown that ginkgo biloba polysaccharide can regulate the activity of glucose metabolism enzymes, promote the secretion of insulin from pancreatic islets, inhibit gluconeogenesis, and promote the utilization of glucose by peripheral tissues, so as to achieve the effect of lowering blood glucose.

Ginkgo biloba polysaccharide can promote cholesterol elimination through binding and adsorption of lipids in the blood, blocking its circulation in the liver and intestines, to achieve the effect of lowering blood lipids.

3) Preventing and controlling cardiovascular diseases

Research shows that ginkgo biloba polysaccharide can significantly prolong the formation of thrombus time, reduce the platelet attachment rate and blood erectile dysfunction, to prevent and control cardiovascular diseases.

4）Anti-ulcer effect

Ginkgo biloba polysaccharide can obviously inhibit the formation of stress-type gastric ulcer in rats and promote the healing of acetic acid-type gastric ulcer, and it has no effect on the secretion of gastric acid and pepsin activity. The efficacy of 124 cases of duodenal ulcers treated with ginkgo biloba polysaccharide was observed, with the recent effective rate of 98.6% and the recent healing rate of 79.03%.

5）Anti-coagulation, promote wound healing effect

Ginkgo biloba polysaccharide can affect the endogenous coagulation system, prolong the time of partial thrombin and realize the anticoagulant effect. In addition, the ginkgo biloba polysaccharides can protect the traumas and prevent infections, which can make the traumas along the physiological repair pathway smoothly.

Application development of ginkgo biloba polysaccharide in foodstuffs

As a biologically active macromolecular substance, ginkgo biloba polysaccharides are commonly used in food products as food fortification agents, anticoagulants, emulsifiers, thickening agents and so on.

Using the thickening and emulsifying properties of silver fungus polysaccharide to develop silver fungus noodles, silver fungus cookies, silver fungus yogurt and silver fungus jelly and other products. These products are made with silver ear polysaccharide as raw material added to the products, after special technology and processing methods made with certain health care functions.
