Kev Siv
1. Siv rau hauv kev lag luam los ua cov tshuaj pleev ib ce: kojic acid tuaj yeem tiv thaiv kev tsim cov tyrosinase, yog li nws tuaj yeem tiv thaiv kev tsim cov melanin hauv daim tawv nqaij, thiab nws muaj kev nyab xeeb thiab tsis muaj tshuaj lom, thiab yuav tsis tsim cov kab mob vitiligo, yog li kojic acid tau sib xyaw rau hauv cov tshuaj pleev ib ce, lub ntsej muag, tshuaj pleev ib ce, tshuaj pleev ib ce, thiab ua rau cov tshuaj pleev ib ce zoo uas tuaj yeem kho cov quav hnav, cov pob laus, cov xim, pob txuv, thiab lwm yam. Qhov concentration ntawm 20ug / ml kojic acid tuaj yeem tiv thaiv 70 ~ 80% ntawm kev ua haujlwm ntawm ntau yam tyrosinase (lossis polyphenol oxidase PPO), thiab qhov ntxiv dav dav hauv cov tshuaj pleev ib ce yog 0.5 ~ 2.0%.
2. Siv rau hauv kev ua zaub mov: kojic acid tuaj yeem siv ua cov khoom noj khoom haus ntxiv rau kev khaws cia, tshuaj tua kab mob thiab antioxidant. Kev sim tau ua pov thawj tias kojic acid tuaj yeem tiv thaiv kev hloov pauv ntawm sodium nitrite mus rau hauv carcinogenic nitrosamines hauv cov nqaij haus luam yeeb, thiab ntxiv kojic acid rau hauv zaub mov yuav tsis cuam tshuam rau saj, aroma thiab kev ntxhib los mos ntawm zaub mov. Kojic acid kuj yog cov khoom siv raw rau kev tsim cov maltol thiab ethyl maltol, thiab siv dav hauv kev ua zaub mov.
3. Siv rau kev kho mob: vim kojic acid tsis muaj kev hloov pauv rau cov hlwb eukaryotic, thiab tuaj yeem tshem tawm cov dawb radicals hauv tib neeg lub cev, txhim kho kev txav mus los ntawm cov qe ntshav dawb, thiab lwm yam, uas yog qhov zoo rau tib neeg kev noj qab haus huv, yog li kojic acid tau siv los ua cov khoom siv raw rau cephalosporin tshuaj tua kab mob, thiab cov tshuaj tiav lawm yog siv los kho mob taub hau, mob hniav thiab mob hauv zos thiab lwm yam kab mob, thiab cov teebmeem analgesic thiab anti-inflammatory yog qhov zoo tagnrho.
4. Cov tshuaj tua kab ua liaj ua teb: kojic acid siv tau los tsim cov tshuaj tua kab mob. Cov tshuaj chiv me me (kua liab tsaus) ua los ntawm 0.5 ~ 1.0% kojic acid, txawm tias nws yog tshuaj tsuag ua cov chiv nplooj ntawm qhov concentration qis, lossis ua rau cov qoob loo loj hlob rau kev siv hauv paus, cov tshuaj txhawb nqa qoob loo no muaj qhov cuam tshuam pom tseeb rau kev nce qoob loo rau cov nplej thiab zaub.
Ntim thiab Xa Khoom
Ntim: 25kg / nruas, 200kg / nruas lossis raws li cov neeg siv khoom xav tau.
Kev xa khoom: yog cov tshuaj lom neeg thiab tuaj yeem xa los ntawm tsheb ciav hlau, dej hiav txwv thiab huab cua.
Tshuag: muaj 500MTs kev nyab xeeb Tshuag
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
