Tartaric acid, tseem hu ua 'kojic acid' lossis 'kojic acid', yog cov khoom lag luam microbial fermentation pom nyob rau hauv cov kua ntses, kua taum paste, wine brewing, thiab tuaj yeem kuaj pom hauv ntau cov khoom fermented fermented los ntawm Aspergillus.
Cov kws tshawb fawb ntxov tshaj plaws pom tias txhais tes ntawm brewery poj niam cov neeg ua haujlwm tshwj xeeb yog dawb. Tom qab kev tshawb fawb ntawm cov khoom fermentation, nws tau pom tias tsis yog tsuas yog muaj lub luag haujlwm zoo hauv kev khaws cia cov freshness ntawm curvilinear acid. Nws kuj muaj ib tug zoo whitening thiab brightening nyhuv. Txawm li cas los xij, daim tawv nqaij tsis muaj kev txhawj xeeb. Ntau tus kws kho hniav nyob sab Europe thiab Asmeskas siv 2 mus rau 4% ntawm kojic acid los kho chloasma hauv lawv cov neeg mob uas muaj txiaj ntsig zoo.
Kojic acid tuaj yeem cuam tshuam kev ua haujlwm ntawm tyrosinase thiab nres kev tsim cov melanin. Kojic acid ntawm qhov concentration ntawm 20 μg / ml tuaj yeem cuam tshuam kev ua haujlwm ntawm ntau tyrosinase enzymes los ntawm 70% -80%. Hauv cov tshuaj pleev ib ce, nws raug nquahu kom ntxiv 0.5% -2% ntawm tretinoin, uas tuaj yeem cuam tshuam kev tsim cov melanin thiab ua tiav cov nyhuv ntawm whitening thiab lub teeb me ntsis.

Kkojic acid tuaj yeem cuam tshuam cov haujlwm ntawm hyaluronidase, yog li nws tuaj yeem tiv thaiv kev ua xua.
Kojic acid, zoo ib yam li VC, khi rau tooj liab ions thiab inactivates tyrosinase.
Kojic acid kuj inhibits zus tau tej cov melanin oxidation intermediates. Kojic acid yog oxidised los ntawm nruab nrab dopaquinone, yog li txo cov saw cov tshuaj tiv thaiv substrate thiab inhibiting kev hloov ntawm melanin nruab nrab ntawm dopaquinone daim ntawv mus rau qhov kawg melanin.
