Abstract

The invention discloses a preparation method of a tremella fermentation extract and application thereof in cosmetics. According to the method, tremella and water are taken as raw materials, and the tremella fermentation extract is obtained by high-temperature fermentation, superspeed shearing and stirring, low-temperature fermentation and sterilization and centrifugal separation, wherein a high-temperature bacterium for high-temperature fermentation is selected from at least one of streptococcus thermophilus and streptococcus salivarius thermophilus; and a low-temperature bacterium selected for low-temperature fermentation is a bacterium obtained mixing yeast and lactobacilli. The tremella fermentation extract prepared with the method can be used as facial mask essence, can be further prepared into a facial mask for moisturizing skin and retaining moisture. The raw materials used in the invention are all additives acceptable in cosmetics, the tremella self (with tremella polysaccharide) has the effects of moisturizing skin and retaining moisture, after microorganism fermentation in a temperature-changing process, the tremella polysaccharide is higher in content and smaller in molecular weight in the extract, and absorption and skin moisturizing and moisture retention on the surface of human skin can be facilitated.

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...
