Commercialized technological conditions for extraction of polysaccharide from Tremella Fuciformis as well as its stability and function in skin care cosmetics were studied.Results showed that the optimum extraction conditions are:using de-ionized water as the solvent with mass ratio of dried Tremella Fuciformis raw material to water 1∶100,extraction time 4 h,temperature at 90 ℃,and pH at about 9.0.Tremella Fuciformis polysaccharide(TFP) has good stability as well as excellent moisturizing effect and antiwrinkle effect.It can improve the skin texture,lower the skin harshness and increase the skin flexibility.
