Therefore, safe cosmetic raw materials and products with outstanding efficacy have good prospects in the market.
Grain such as sorghum, barley, wheat and corn contains rich nutrients including protein, beta-glucan, phenolic substances, flavonoid substances, cellulose and the like, and is a common raw material for brewing wine. The distillers 'grains are by-products of the fermentation of the grains by the yeast, and the residual active metabolites of the distilled liquor are not utilized in the distillers' grains. The distilled spirit vinasse is rich in various healthy and natural fermentation source skin beautifying components, and mainly contains amino acids in natural moisturizing factors, so that human cells can be synthesized, degradation or aging of the cells can be prevented, bone collagen can be decomposed, and skin can keep elasticity. In addition, the moisture-preserving components such as polysaccharide, organic acid and polyphenol in the distilled grains are beneficial to improving the skin moisture-preserving function, moistening the skin and improving the skin problems caused by skin dryness. The distilled spirit vinasse has the advantages of wide source, high yield and low price, has great development potential and good application prospect, and the main treatment mode is to discard or manufacture animal feed, so that the environment is influenced, and the value of the distilled spirit vinasse is not fully utilized. At present, a development and utilization way of distillers' grains with high economic added value is still lacking.
