Propyl gallate tau dhau los ua ib qho tseem ceeb ua haujlwm ntxiv hauv kev lag luam niaj hnub no vim nws ntau - lub hom phiaj antioxidant mechanism thiab hla kev qhuab qhia. Los ntawm kev khaws cov zaub mov mus rau kev kho mob, los ntawm cov qauv tshuaj pleev ib ce mus rau cov khoom lag luam ruaj khov, nws daim ntawv thov ciam teb txuas ntxiv txuas ntxiv nrog kev tsim kho tshiab. Nyob rau hauv lub neej yav tom ntej, nrog breakthroughs nyob rau hauv ntsuab synthesis txheej txheem thiab nanoformulation technology, propyl gallate yuav tsum ua lub luag hauj lwm ntau dua nyob rau hauv precision tshuaj, siab - kawg manufacturing, thiab lwm yam teb, pab rau tib neeg noj qab haus huv thiab sustainable kev loj hlob.

Synthesis ntawm propyl gallate:
Cov txheej txheem belongs rau kev teb ntawm kev npaj antioxidant. Nyob rau hauv txoj kev no, Suav nutgall yog thawj khob, cored, crushed, thiab crushed hmoov yog feem roasted, steamed, fermented, thiab fermentation kua yog sau. Tom qab ntawd cov kua fermentation yog muab tso rau hauv ib qho chaw ventilated, acidified nrog concentrated sulfuric acid, ntxiv nrog n-propanol, nplawm, sib tov, thiab rhuab kom tau txais edible acid propyl acetate. Cov txiaj ntsig ntawm propylacetate gallate npaj los ntawm txoj kev yog siab, ncav cuag ntau dua 97%; Cov txheej txheem npaj yog yooj yim, ntsuab thiab muaj kuab paug-dawb, thiab ib puag ncig tiv thaiv.

Reaction mechanism ntawm propyl gallate:
Cov haujlwm ntawm antioxidants yog complex thiab muaj ntau yam, tab sis lub ntsiab cov tshuaj tiv thaiv mechanism yog: cov antioxidants tso hydrogen atoms thiab ua ke nrog cov peroxide uas ua los ntawm cov tsis siv neeg oxidation cov tshuaj tiv thaiv ntawm roj thiab rog, rhuav cov saw cov tshuaj tiv thaiv, yog li tiv thaiv cov txheej txheem oxidation mus ntxiv.
Phenolic antioxidants (BHA, BHT, TBHQ, PG, thiab lwm yam) tuaj yeem muab cov hydrogen atoms los ua ke nrog cov dawb radicals uas tsim los ntawm kev tsis siv neeg oxidation ntawm cov roj thiab cov rog kom ruaj khov, tsis tshua muaj zog dawb radicals ntawm antioxidants, yog li ntawd cov tshuaj tiv thaiv oxidation ntawm cov roj thiab cov rog tsis tuaj yeem sib kis thiab ua tiav lub hom phiaj ntawm kev tiv thaiv - oxidation.
Cov ntaub ntawv keeb kwm yav dhau los ntawmpropyl gallate hmoov:
Txhawm rau tiv thaiv cov rog lossis roj-raws li cov zaub mov los ntawm rancidity thiab aftertaste vim tsis siv neeg oxidation nyob rau hauv cov huab cua, qee cov zaub mov antioxidants feem ntau yog ntxiv ntxiv rau cov pa cais tawm lossis deoxygenated cia txoj kev. Roj soluble antioxidants feem ntau siv hauv cov zaub mov hauv tsev thiab txawv teb chaws suav nrog butyl hydroxyanisole (BHA), dibutyl hydroxytoluene (BHT), tert butyl hydroquinone (TBHQ), propyl gallate (PG), thiab lwm yam.
Txawm li cas los xij, BHT muaj cov ntxhiab tsw phem thiab cov kab mob carcinogenic rau cov nas, uas tau txwv hauv qee lub tebchaws; Tus nqi synthesis ntawm BHA yog siab thiab nws toxicity yog siab. Txawm hais tias nws muaj cov nyhuv carcinogenic tseem nyob hauv kev sim; TBHQ yog ib qho yooj yim rau volatilize ntawm qhov kub thiab txias thiab tej zaum yuav lom rau tsiaj lub cev yog tias noj ntau dhau. Hauv qhov sib piv, PG tsis yog tsuas yog cov tshuaj lom neeg tsawg, kev nyab xeeb siv, tab sis kuj zoo dua rau BHT thiab BHA hauv kev tiv thaiv oxidation. Yog li ntawd, nws yog dav siv nyob rau hauv edible oils, pub, kib zaub mov, qhuav ntses cov khoom, muaj roj nplua nuj biscuits, kaus poom thiab kho cov nqaij cov khoom, thiab yog ib tug ntawm cov zoo heev roj antioxidants pom zoo los ntawm lub Food and Agriculture Organization of the United Nations (FAO) thiab World Health Organization (WTO).
