Nyob rau hauv kev tsim khoom thiab ntim ntawm ntau cov ntaub ntawv, khoom noj, tshuaj pleev ib ce thiab cov khoom lag luam oxidation yog ib qho ntawm cov tsis zoo, ua rau muaj kev phom sij thiab kev phom sij kev nyab xeeb. Antioxidants tuaj rau hauv kev ncua oxidation thiab txhim kho cov khoom ruaj khov. Rau raw khoom siv cov khoom siv rawers
1. Dab tsi yog antioxidants?
Antioxidants yog chav kawm cov tshuaj uas tuaj yeem ncua lossis siv cov roj hmab, roj hmab, cov roj, tshuaj, tshuaj pleev ib ce, tshuaj pleev ib ce thiab lwm thaj teb. Nws cov haujlwm tseem ceeb yog:
Neutralize los yog ntes dawb radicals (reactive oxygen hom, Ros);
Thaiv qhov kev tshaj tawm ntawm oxidation cov tshuaj tiv thaiv;
Tiv thaiv cov khoom tseem ceeb los ntawm kev ua oxidized thiab decomposed los ntawm oxygen, lub teeb, kub lossis hnyav hlau manalysis;
Txuas ntxiv lub txee lub neej lossis kev pabcuam lub neej ntawm cov khoom.
2. Ua haujlwm ua haujlwm ntawm Antioxidants: thaiv cov oxidation ntawm qib molecular
Oxidation cov tshuaj pheej feem ntau tshwm sim hauv daim ntawv ntawm radicals dawb, thiab cov txheej txheem yog txoj saw hloov:
Pib theem: lub zog sab nraud (xws li lub teeb thiab cua sov) ua kom cov khoom siv raw lwg me me los tsim cov dawb radicals;
Cov theem txuas ntxiv: dawb radicals tua lwm cov molecules los ua cov tshuaj dawb tshiab radicals, thiab cov tshuaj tiv thaiv kis tau zoo;
Kev txiav tawm theem: Ob lub radicals sib txuas ua ke los ua cov lwg me me, thiab cov saw sib txuas nres.
Antioxidants tsuas yog ua ib lub luag haujlwm hauv kev pib thiab txuas ntxiv qib:
Txais cov radicals dawb: xws li phenolic antioxidants neutralize dawb radicals los ntawm muab cov athrogen atoms;
Decomposing peroxides: tiv thaiv lawv los ntawm kev txuas mus ntxiv los tsim cov dawb radicals;
Ion Chelation: Txo cov kev hloov pauv hlau catalytic oxidation txheej txheem;
Sib haum ib zaj duab xis tiv thaiv lossis teeb meem los txo kev sib cuag ntawm oxygen thiab tshuaj.
Nws cov essence yog kom "cuam tshuam cov tshuaj tiv thaiv oxidation oxidation" ntawm qib molecular los tiv thaiv cov khoom ntawm cov khoom.
3. Lub hauv paus ntawm cov hom hluavtaws: sib piv ntawm ob hom kev tiv thaiv kab mob antioxidants
Antioxidants tuaj yeem faib ua ob pawg raws li lawv cov peev txheej raws li lawv cov peev txheej raws li lawv cov khoom siv tau) thiab cov hluavtaws tsim nyog), ** Txhua daim teb uas siv tau thiab cov txiaj ntsig zoo thiab qhov tsis zoo:
HOM NTAU YAM KHOOM ZOO TSHAJ PLAWS DAIM NTAWV THOV KEV PAB CUAM
Ntuj antioxidants cog thiab tsiaj cov khoom lag luam, cov tshuaj yej muaj txiaj ntsig, tshuaj ntsuab, tshuaj pleev ib ce, tshuaj, ntuj, thiab lwm yam.
Cov hluavtaws hluavtaws npaj tau los ntawm cov khoom siv raw, xws li BHT (BHA, thiab qee yam kev pheej hmoo, thiab qee cov roj hmab tau txwv los ntawm cov kev cai roj hmab, yas, Roj nplua, roj, txheej, khoom siv cable, thiab lwm yam.
Rau cov neeg xa khoom, kev xaiv ntawm ntuj lossis hluavtaws antioxidant yuav tsum raug pom zoo raws li cov kev cai tswj hwm ntawm cov neeg siv khoom lag luam kev lag luam, ntsuas kub, cov qauv ntsuas chaw thiab lwm yam.
4. Cov Khoom Siv Ua kom pom tseeb: Daim ntawv thov sib txuam ntawm cov tshuaj tiv thaiv kab mob antioxidants thiab cov khoom lag luam sib txawv
Kev muab cov khoom lag luam antioxidant tsis yog hais txog kev ntxiv, tab sis tseem ceeb tshaj, nws yog qhov ua yeeb yam zoo, nws yog kev tswj hwm {}}} ua raws cov kev daws teeb meem tag nrho:
Roj Hmab thiab Kev Lag Luam Yas: Saib rau DUAL inhibition ntawm thermal oxidation laus thiab ultraviolet laus;
Khoom noj khoom haus / kws tshuaj ntsuam xyuas: qhia txog cov khoom xyaw ntuj thiab cov seem qis;
Tshuaj pleev ib ce kev lag luam: caum "efficacy + me me" thiab xum cog cov khoom cog;
Cov roj nplua nyeem thiab roj Kev Lag Luam: Xav tau kev ntsuas kub thiab ntev- lub sij hawm tiv thaiv.
Ib qho ntxiv, qee cov khoom siv txuas ntxiv txhim kho cov ntawv thov kev ua tau zoo los ntawm kev tsim cov tshuaj antioxidant +, uas yog ib qho kev taw qhia tseem ceeb rau cov khoom lag luam ntxiv.
Xaus: antioxidants yog "qab --} scenes heroes" ntawm cov khoom ruaj khov
Niaj hnub no, thaum "ntsuab, muaj kev nyab xeeb, thiab ntev - kav" tau dhau los ua cov haujlwm tseem ceeb, tab sis kuj tseem muaj cov haujlwm tseem ceeb, tab sis kuj tseem muaj kev txhawb nqa tseem ceeb ntawm kev tswj hwm thiab cov neeg siv khoom. Rau cov neeg xa khoom ntawm cov khoom siv raw thiab cov quav ntxiv, sib sib zog nqus ntawm cov ntsiab cai antioxidans yog qhov tseem ceeb ua kom muaj kev lag luam siab.
