Description

Cosmetic based on beer brewing waste residue extract and preparation method thereof

Technical Field

The invention relates to a cosmetic based on a beer brewing waste residue extract and a preparation method thereof.

Background

The beer brewing process comprises the steps of crushing, gelatinizing and saccharifying, fermenting, filling and the like, obtaining a mixture containing components such as starch, protein, amino acid, enzyme and the like after the gelatinizing and saccharifying process, and filtering liquid and solid components. Adding flos Lupuli into the filtrate, heating to dissolve the fragrance, bitterness and anti-inflammatory components of flos Lupuli into the filtrate, adding yeast, and allowing the wort to form a solution containing CO₂Alcohol and a substance with flavor, namely 'light beer', are added with diatomite and a diatomite filter aid for filtration to obtain the beer to be filled and the beer brewing waste residue.

The beer yeast fermentation liquor and the hops in the beer production process have certain antibacterial, anti-inflammatory and antioxidant effects and are used in cosmetic formulations for oral cavity, hair washing, face care and the like. However, since a large amount of brewery waste generated by breweries as production waste requires additional economic cost for disposal, at present, most of brewery waste is treated as waste, and there are reports on producing feed additives by fermentation.

The principle of the facial mask aims to temporarily isolate outside air and pollution, improve skin temperature, expand skin pores, and promote sweat gland secretion and skin metabolism within a time range of covering facial skin. The use of the facial mask is beneficial to exerting the effects of secondary cleaning, moisturizing, whitening, anti-aging and the like on the skin, and is beneficial to maintaining a healthy skin barrier. At present, no research report exists that a large amount of beer brewing waste residues generated in the beer production process are specially treated, and then are changed into valuables to obtain a beer brewing waste residue extract with anti-inflammatory, antibacterial and other effects, and the extract is applied to daily skin care.
