Description

Technical Field

[0001] The invention relates to the technical field of rice processing, and in particular to a method for preparing a traditional Chinese medicine whitening and freckle-removing skin care product by utilizing rice fermentation filtrate. Background Art

[0002] Rice is a staple food that people often eat. After yeast fermentation, nutrients such as starch, protein, and fat are broken down into small molecule sugars, peptides, amino acids, organic acids and other rich nutrients, which have multiple functions such as antioxidant and whitening.

[0003] At present, when skin care products made from rice fermentation filtrate are used in the market, most of them remove the rice bran from the rice, but the rice bran contains a high amount of oryzanol, which leads to the loss of nutrients in the rice, and the skin has a poor absorption effect on the rice fermentation filtrate, resulting in poor use effect of the skin care products. Therefore, it is urgent to design a method for making traditional Chinese medicine whitening and freckle-removing skin care products using rice fermentation filtrate to solve the above problems.
