What is Tremella fuciformis polysaccharide and its function?
Tremella fuciformis is rich in nutrients, including protein, fat, vitamins, minerals, and other nutrients. Protein accounts for 6% -10% of dry weight and contains 17 types of amino acids, including 7 essential amino acids for the human body; The fat content is 0.6% -1.28%, mainly composed of unsaturated fatty acids such as linoleic acid, with an unsaturated proportion of about 75%. In addition, Tremella fuciformis contains rich inorganic salts such as calcium, iron, magnesium, and phosphorus, as well as various vitamins, which have high nutritional value.
Tremella fuciformis polysaccharides are the main active ingredients in Tremella fuciformis, accounting for more than 60% of its dry weight. They include five types: acidic heteropolysaccharides, neutral heteropolysaccharides, cell wall polysaccharides, and acidic oligosaccharides. Among them, acidic heteropolysaccharides are the main polysaccharides, accounting for about 70% -75% of the total sugar in Tremella fuciformis, and are oligomers of xylose, mannose, glucuronic acid, etc. Neutral heteropolysaccharides account for about 20% of total sugars and are oligomers composed of xylose, mannose, galactose, and glucose. The commonly mentioned polysaccharides in Tremella fuciformis refer to acidic heteropolysaccharides and neutral heteropolysaccharides.
Tremella fuciformis polysaccharides have various physiological functions such as improving immunity, anti-tumor, anti-aging, lowering blood sugar and blood lipids, and are excellent functional food ingredients. The application of Tremella fuciformis polysaccharides in the field of functional foods is mainly focused on functional diets, and there are also some health foods involved, but the quantity is not large. There are two main reasons:
1. Tremella fuciformis polysaccharides are abundant and readily available, but their status as a health food does not significantly enhance their sense of value;
2. The positioning of Tremella fuciformis is more popular, and the form of functional diet is closer to consumers. In addition, the cosmetics industry is an emerging field for the functional application of Tremella fuciformis polysaccharides. Studies have shown that Tremella fuciformis polysaccharides have even better moisturizing effects than hyaluronic acid, and can help fade areas such as melasma and freckles, making them a potential skin treatment ingredient.
Polysaccharides are commonly used stabilizers and emulsifiers in food, playing an important role in improving food quality. Tremella fuciformis polysaccharide is also an excellent improver in food. It can be used in products that require thickening, emulsification, stabilization, and water retention, and has significant effects. It has good coordination with other ingredients and can exert synergistic effects. The most important thing is that Tremella fuciformis polysaccharides do not require controlling the "quantity" issue and are easy to widely use in food.
The use of Tremella fuciformis polysaccharides in food processing can not only improve product texture, but also endow products with certain functionality. It is a multifunctional food "additive" with good application prospects.
