Kev ua tau zoo thiab lub luag haujlwm
1. Ua kom tawv nqaij tawv
Inhibit tsim melanin
Tom qab ascorbic acid glucoside hloov mus rau hauv vitamin C thiab nkag mus rau ntawm daim tawv nqaij hlwb, nws txo qhov tsim ntawm melanin los ntawm inhibiting qhov kev ua ntawm tyrosinase. Inhibiting tyrosinase txo dopaquinone, ib qho nruab nrab ntawm kev sib txuas ntawm melanin. Lwm qhov txiaj ntsig ntxiv yog tias nws tseem hloov dopaquinone rau hauv levodopa, uas txo cov tsim melanin thiab yog li txo cov tawv nqaij pigmentation.
2. Tiv thaiv UV puas
Inhibit cell puas los ntawm ultraviolet hluav taws xob
Tom qab ascorbic acid glucoside hloov mus rau hauv vitamin C, nws tuaj yeem txo cov dawb radicals uas tsim los ntawm ultraviolet rays ntawm daim tawv nqaij, txo cov tawv nqaij puas tsuaj, thiab ua lub luag haujlwm tiv thaiv daim tawv nqaij hauv cov khoom siv tshuaj pleev thaiv hnub.
3. Anti-aging
Txhawb collagen synthesis thiab txhim kho wrinkles thiab tawv tawv
Collagen yog cov protein uas ua lub luag haujlwm tseem ceeb hauv daim tawv nqaij thiab kev tiv thaiv. Ascorbyl glucoside hloov mus rau hauv vitamin C thiab nkag mus rau hauv daim tawv nqaij hlwb rau collagen synthesis hauv fibroblasts. Nws muaj cov txiaj ntsig pom tseeb ntawm kev txo qis wrinkles thiab tawv nqaij.
Daim ntawv thov
Ascorbic acid glucoside yog ib qho ntawm cov tshuaj ntxuav hniav dawb tau pom zoo los ntawm Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv thiab tau lees paub tias yog cov vitamin C derivative ruaj khov tshaj plaws. Nws kuj yog qhov feem ntau siv whitening muaj nyob ntawm cov hom loj. Ascorbic acid glucoside tsis tsuas yog muaj txiaj ntsig zoo rau cov tawv nqaij, tab sis kuj yog tshuaj lom neeg ruaj khov thiab tsis ua rau tawv nqaij. Nws yog dav siv hauv tshuaj pleev ib ce hauv tsev thiab txawv teb chaws thiab tau lees paub los ntawm pej xeem.
Nws tuaj yeem pom los ntawm kev siv cov vitamin C derivatives hauv cov tshuaj pleev ib ce uas feem ntau siv ascorbic acid derivatives tam sim no yog: ascorbic acid glucoside, ascorbyl palmitate, ethyl ascorbic acid, sodium ascorbyl phosphate, thiab lwm yam. Nws tsis yog tsuas yog siv hauv cov khoom siv ntxuav hniav dawb. , tab sis kuj muaj ntau daim ntawv thov hauv kev tiv thaiv kev laus thiab tshuaj pleev thaiv hnub. Nyob rau hauv cov mis ntawm whitening tshuaj pleev ib ce, vitamin C derivatives yog tsuas yog siv rau lawv anti-free radical thiab melanin txo zog. Hauv cov khoom siv los tiv thaiv kev laus thiab moisturizing, lawv tsuas yog siv rau lawv txoj haujlwm ntawm kev txhawb nqa collagen kev loj hlob, tiv thaiv kev laus, thiab moisturizing. Tsis tas li ntawd, tom qab tau nqus los ntawm daim tawv nqaij, nws kuj tuaj yeem ua rau lub hnub ci zoo, yog li nws kuj yog ib qho ntawm cov khoom siv raw feem ntau xaiv hauv cov khoom siv tshuaj pleev thaiv hnub.
Ascorbic acid glucoside yog dav siv hauv kev lag luam tshuaj pleev ib ce, thiab feem ntau ntawm cov npe loj uas muaj txiaj ntsig zoo siv ascorbic acid glucoside. Hauv kev ua lag luam Esxias, ascorbic acid glucoside yog siv los ua cov khoom ua kom tawv nqaij, tab sis nyob rau sab hnub poob, cov neeg dawb tsis tas yuav ua kom tawv nqaij. Yog li ntawd, cov khoom xyaw no tau siv dav los ua cov khoom xyaw antioxidant. Nyob rau hauv cov mis ntawm whitening tshuaj pleev ib ce, vitamin C derivatives yog tsuas yog siv rau lawv anti-free radical thiab melanin txo zog. Hauv cov khoom siv los tiv thaiv kev laus thiab moisturizing, lawv tsuas yog siv rau lawv txoj haujlwm ntawm kev txhawb nqa collagen kev loj hlob, tiv thaiv kev laus, thiab moisturizing.

Whitening txoj cai
Cov ntsiab lus ntawm melanin hauv tib neeg daim tawv nqaij txiav txim siab xim ntawm daim tawv nqaij. Tyrosine yog cov khoom siv tseem ceeb rau kev tsim melanin. Tyrosinase yog tus nqi-txheej enzyme nyob rau hauv txoj kev tyrosine synthesis. Nws feem ntau cuam tshuam rau kev hloov pauv ntawm tyrosine rau hauv Dopa, thiab oxidation ntawm dopa rau dopaquinone cuam tshuam rau kev tsim cov melanin. Lub tshuab ntxuav hniav dawb ntawm ascorbic acid glucoside yog siv L-tyrosine ua lub substrate los tiv thaiv kev tsim cov melanin los ntawm inhibiting cov haujlwm ntawm tyrosinase.
Kev npaj
Cov txheej txheem synthesis ntawm ascorbic acid glucoside tsuas yog siv cov nyhuv transglycosylation ntawm glycosyltransferase rau biotransformation thiab synthesis. Kev xaiv ntawm glycosyltransferase yog qhov tseem ceeb heev hauv cov txheej txheem synthesis. Cov khoom tsim ntawm cov glycosyltransferases sib txawv, feem ntau nyob rau hauv cov suab thaj sib txawv txuas nrog cov qauv vitamin C. Feem ntau ntawm cov khoom yog cov khoom sib tov, thiab cov khoom tsis yooj yim sib cais. Yog li ntawd, xaiv qhov tsim nyog hloov pauv muaj feem cuam tshuam ntau dua rau qhov purity thiab tawm los ntawm cov khoom siv tshuaj tiv thaiv. Tam sim no feem ntau siv xws li cyclomaltodextrin glucan transferase, -amylase, -glucosidase, thiab lwm yam.
Ib txoj kev tsim khoom ntawm ascorbic acid glucoside, tus cwj pwm hauv qhov nws suav nrog cov hauv qab no:
Kauj Ruam 1: Cov tshuaj ascorbic acid glucoside cov tshuaj tiv thaiv yog sib cais los ntawm nanofiltration, thiab cov seem VC hauv cov tshuaj tiv thaiv raug tshem tawm kom tau txais nanofiltration concentrate;
Kauj Ruam 2: cais cov nanofiltration concentrate los ntawm kev sib cais cov kua dej txuas ntxiv kom tshem tawm cov piam thaj los ntawm VC glucoside cov tshuaj tiv thaiv;
Kauj Ruam 3: Cov tshuaj VC glucoside tawm los ntawm cov kua dej txuas ntxiv yog thawj zaug hloov kho los ntawm cation resin los kho cov pH, thiab tom qab ntawd cov concentrated los ntawm nanofiltration membrane kom tshem tawm cov ntsev inorganic hauv cov tshuaj tiv thaiv kom tau txais VC glucoside concentrated tov;
Kauj Ruam 4: Ua kom pom tseeb ntawm VC glucoside mloog zoo los ntawm kev distillation nyob rau hauv qhov txo qis, ntxiv cov concentration ntawm VC glucoside, thiab tom qab ntawd crystallize kom tau VC glucoside.
Kev ua si lom neeg
O- -D-Glucopyranosyl-l-ascorbicacid (AA-2G) yog glucoside derivative ntawm ascorbic acid ascorbicacid (AA), uas qhia cov vitamin C ua haujlwm tom qab enzymatic hydrolysis rau ascorbic acid ascorbicacid. Kev tiv thaiv qog nqaij hlav ntawm AA-2G yog tshwm sim los ntawm ROS tsim los ntawm AA tso tawm los ntawm hydrolysis sai ntawm AA-2G.
