Functional characteristics of Tremella fuciformis polysaccharides
1. Processing characteristics in food production
Tremella polysaccharides contain a significant amount of homogeneous polysaccharides (approximately 70-75% of total polysaccharides), which have the ability to increase solution viscosity and emulsify and stabilize. Therefore, when applied in the processing of beverages, dairy products, and cold drinks, they not only give food good processing characteristics, but also reduce the use of synthetic additives and improve the nutritional value of food. 2. Health and medicinal effects. The composition of Tremella fuciformis polysaccharides is diverse, with not only diverse monomers, but also diverse configurations and conformations after forming polymers. When multiple polysaccharides are mixed together, their biological activities are also diverse. Modern research has fully confirmed that Tremella fuciformis polysaccharides have multiple medical and health functions, which can be summarized as follows: 1) Immunomodulatory and anti-tumor effects For many years, scientists have discovered that Tremella fuciformis polysaccharides are involved in regulating various cellular life phenomena, such as the transmission and perception of information between immune cells, activation of immune cells, and enhancement of the body's immune function. Through this participation, Tremella fuciformis polysaccharides can not only exert anti-tumor effects by enhancing host immune function, but also directly kill tumor cells through pathways such as directly acting on tumor cells or inducing tumor cell apoptosis. 2) Studies have shown that Tremella fuciformis polysaccharides can regulate the activity of glucose metabolism enzymes, promote insulin secretion in the pancreas, inhibit gluconeogenesis, promote the utilization of glucose by peripheral tissues, and thus achieve the effect of lowering blood sugar Tremella polysaccharides can promote cholesterol elimination by binding and adsorbing lipids in the blood, block their circulation in the liver and intestines, and achieve the effect of reducing blood lipids. 3) Research on the prevention and treatment of cardiovascular diseases has shown that Tremella fuciformis polysaccharides can significantly prolong the formation time of blood clots, reduce platelet adhesion rate and blood erection, and achieve the effect of preventing and treating cardiovascular diseases. 4) The anti ulcer effect of Tremella fuciformis polysaccharides can significantly inhibit the formation of stress induced gastric ulcers in rats, promote the healing of acetic acid induced gastric ulcers, and have no effect on gastric acid secretion and pepsin activity. The therapeutic effect of using Tremella fuciformis polysaccharides to treat 124 cases of duodenal ulcers was observed, with a recent effective rate of 98.6% and a recent healing rate of 79.03%. 5) Anticoagulant and promoting wound healing effects. Tremella fuciformis polysaccharides can achieve anticoagulant effects by affecting the endogenous coagulation system and prolonging partial thrombin time. In addition, Tremella fuciformis polysaccharides have a protective effect on the wound surface and a preventive effect on infection in the experimental rats, which can facilitate the smooth physiological repair of the wound 02
Application and Development of Tremella Polysaccharides in Food
Tremella fuciformis polysaccharides, as a bioactive macromolecular substance, are widely used in food development and can be used as food fortifiers, anticoagulants, emulsifiers, thickeners, etc. Convenient tremella and jujube soup developed by utilizing the good rehydration ability of tremella polysaccharides, instant instant mixing products such as tremella milk powder, tremella bean milk powder, and tremella oatmeal; Products such as Tremella noodles, Tremella biscuits, Tremella yogurt, and Tremella jelly developed using the thickening and emulsifying properties of Tremella polysaccharides. These products are all made from Tremella polysaccharides as raw materials and processed through special techniques to have certain health benefits.
