Ethanolic fermentation can produce byproducts such as yeast containing intracellular amino acid that is used as a raw material of cosmetics. Residual yeast fermentation as sludge was dissolved and extracted by autolysis at 50°C for 24 hours, so we get the product in the form of intracellular content of the yeast Saccharomyces cerevisiae. Purification of dye and odor yeast extract was conducted by using an activated carbon column adsorption with ratio 1.5:10 yeast extract solution (g / mL) for six times recycle or until it reaches the absorbance value of 0.020. The content of yeast extract in the form of amino acids was analyzed by High-Pressure Liquid Chromatography method. Analysis of the feasibility test yeast extract as cosmetic raw materials made through the pigment deposition method by inhibit tyrosinase activity. 0.05 g yeast extract before adsorption (pale yellow) produce 62% inhibition of tyrosinase 3130 U / mL. Dry yeast extract after adsorption (odorless) had 96% inhibition of tyrosinase 313 U / mL, whereas placental extract by 89% inhibition of tyrosinase 313 U / mL. These results indicate odorless yeast extract can replace placental extract as an alternative to cosmetic raw materials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
