White fungus (Tremella fuciformis Berk), commonly known as white fungus (white jelly fungi), the genus Basidiomycetes fungi (basidiomycetes), silver eyes and ears (Tremellales), white fungus Branch (Tremellaceae), white fungus genus (Tremella); edible part of the fruiting body. Historical records believe fungus sweet, with Yin and lungs, stomach fluid of efficiency, longevity herbs since ancient times been regarded as treasures. Modern scientific research in animal experiments also confirmed that the fungus contains polysaccharides (polysaccharides) can lower blood sugar and low-density cholesterol mice, anti-inflammatory, promoting lymphocyte proliferation and platelet cell activity and increases the activity of splenic macrophages and induce the body to produce induced tumor necrosis factor (tumor necrosis factor, TNF), and the anti-tumor activity, such as the role. In recent years, the United States and Japan and other countries also have a number of active ingredients in Tremella lucuronoxylomannan for the demands of the patent application by including dietary supplements, vascular endothelial cell enhancers, antiallergic agent, and skin moisturizing materials. Natural skin care products safe for mainstream appeal in recent years, the international cosmetics, each leading cosmetics company committed to the development and application of natural material. Although the fungus deep development for the United States Potential capacity maintenance cosmetics can take to increase their additional value; however, in terms of extraction fungus polysaccharides, because of the associated technical immature, unable to obtain a large amount of high-purity polysaccharides for commercial production. In view of this, the Council of Agriculture Agricultural Research Institute in recent years into the antioxidant activity of mushroom polysaccharides tested and developed no added chemicals polysaccharides extraction technology, self fungus fruiting body, spending a lot of polysaccharide substances, and large increase the extraction rate of convergence to 42-50%. Transparent gelatinous fungus contained mainly polysaccharides, Tremella polysaccharides applied to the skin, can form a transparent film, can improve skin water retention, natural moisturizing material, suitable for development into a skin moisturizing skin care products.
