Abstract

The invention discloses a preparation method of tremella fermented extract and its application in cosmetics. The method uses white fungus and water as raw materials to obtain the white fungus fermented extract through high-temperature fermentation, ultra-high-speed shear stirring, low-temperature fermentation, sterilization, and centrifugation; and at least one of Streptococcus salivarius subsp. thermophile; the low-temperature strain selected for the low-temperature fermentation is a strain obtained by mixing yeast and lactobacillus. The white fungus fermented extract prepared by the present invention can be used as a mask essence, and further made into a mask for water replenishment and moisturizing. The raw materials used in the present invention are all additives allowed in cosmetics, and Tremella itself (containing tremella polysaccharide) has the effect of replenishing water and moisturizing. Small in size, it is more conducive to the absorption and moisturizing of the human skin surface.

Description

technical field [0001] The invention belongs to the field of cosmetics, in particular to a preparation method of tremella fermented extract and its application in cosmetics. Background technique [0002] Tremella, also known as white fungus, is a large edible fungus with rich nutrition and delicious taste. It is also a medicinal fungus with high medicinal value. It is a health product recognized all over the world. Tremella is rich in nutrients such as polysaccharides, proteins and various amino acids. Our country is relatively rich in tremella resources, and the research on tremella in the field of medicine and cosmetics is gradually deepening not only in food at this stage. [0003] Tremella extracts, especially tremella polysaccharides, have been used in beauty and skin care products, mainly for anti-aging and moisturizing functions. In recent years, Hao Ying, Qiu Beiyong and others have also applied for some patents on plant or fungal extracts, but most of them add tre...
