tert-Butylhydroquinone (TBHQ) (CAS: 1948-33-0),yog ib qho tshuaj antioxidant zoo heev.Hauv cov khoom noj, tert-Butylhydroquinone yog siv los ua antioxidant hauv cov roj zaub thiab ntau hom roj tsiaj noj.Nws tsis hloov xim thaum raug hlau, thiab tsis hloov lub saj los yog tsw ntawm zaub mov.Nws tuaj yeem siv nrog lwm cov tshuaj tiv thaiv xws li butyl hydroxyanisole (BHA).Nws E code raws li cov khoom noj ntxiv yog E319.Nws yog dav siv nyob rau hauv cov zaub mov vim nws muaj peev xwm ncua nws txee lub neej.Hauv kev tsim khoom, nws tuaj yeem siv los ua tus stabilizer los tiv thaiv tus kheej-polymerization ntawm cov organic peroxides.Nws tuaj yeem muab ntxiv rau biofuel ua tus neeg sawv cev tiv thaiv corrosion.Hauv cov tshuaj tsw qab, TBHQ tuaj yeem siv los ua ib qho fixative, inhibiting volatilization thiab txhim kho stability.Tsis tas li ntawd, nws kuj yog siv nyob rau hauv cov xim, varnishes thiab resins.
tert-Butylhydroquinone (TBHQ) (CAS: 1948-33-0), muaj kev ua haujlwm zoo antioxidant thiab muaj zog antioxidant muaj peev xwm tshaj BHT, BHA, PG (acrylic gallate) thiab vitamin e.Nws tuaj yeem cuam tshuam kev loj hlob ntawm Bacillus subtilis, Staphylococcus aureus, Escherichia coli, pneumococcus thiab lwm yam kab mob, nrog rau Aspergillus niger, Aspergillus variegata, Aspergillus flavus thiab lwm yam kab mob.Kev ua haujlwm antioxidant ntawm TBHQ yog qhov zoo dua li cov tshuaj antioxidants.Raws li cov roj zaub muaj kev txhawj xeeb, lub peev xwm antioxidant yog raws li hauv qab no: TBHQ > PG > BHT > BHA.Ntxiv TBHQ rau cov zaub mov tuaj yeem tsis tsuas yog ncua sijhawm oxidative deterioration ntawm cov roj thiab cov rog, tab sis kuj inhibit ntau yam kab mob.Nws tuaj yeem siv los ua cov tshuaj tua kab mob hauv cov khoom noj uas muaj roj, cov khoom noj kib, cov khoom siv ntses qhuav, biscuits, instant noodles, mov nplej sai, cov txiv hmab txiv ntoo qhuav hauv kaus poom, cov khoom noj nqaij, thiab tuaj yeem siv rau hauv cov tshuaj pleev ib ce.① TBHQ Antioxidants.Haum rau cov roj crude thiab cov roj unsaturated heev, xws li roj sunflower.Rau cov roj ua noj thiab cov khoom ci, nws yuav tsum tau ua ke nrog BHA, tab sis nws tsim nyog rau cov khoom siv boiled thiab kib.Cov koob tshuaj dav dav yog 100 ~ 200 mg / kg.kuaj cov khoom noj roj additives.Nws tuaj yeem tiv thaiv oxidation ntawm cov roj feem ntau, yas, roj hmab, thiab lwm yam. Hlau thiab tooj liab tsis hloov xim, tab sis yog tias muaj alkali, nws tuaj yeem tig liab.Zoo heev oxidation tsis kam.Antioxidants.Tert-butyl hydroquinone yog tsim rau cov roj crude thiab cov roj unsaturated heev, xws li roj sunflower.Rau cov roj ua noj thiab cov khoom ci, nws yuav tsum tau ua ke nrog BHA, tab sis nws tsim nyog rau cov khoom siv boiled thiab kib.Cov koob tshuaj dav dav yog 100 ~ 200 mg / kg.Nws yog siv los ua PVC los tiv thaiv ntses qhov muag tus neeg saib xyuas thiab cov khoom noj ntxiv, ua antioxidant, thiab tuaj yeem siv rau cov roj noj, kib zaub mov, biscuits, instant noodles, instant siav mov, cov txiv hmab txiv ntoo qhuav, cov khoom ntses qhuav thiab kho cov nqaij, nrog rau Kev siv ntau tshaj 0.2 g / kg.
tert-Butylhydroquinone (TBHQ) (CAS: 1948-33-0) yog ib qho kev nyab xeeb thiab muaj txiaj ntsig antioxidant rau cov khoom siv roj thiab cov rog, haum rau cov roj zaub, lard, thiab lwm yam. tshwj xeeb tshaj yog tsim rau cov khoom noj kib vim muaj qhov kub thiab txias thiab kub kub.Cov khoom no kuj muaj cov tshuaj tiv thaiv kab mob zoo, pwm thiab cov poov xab los, uas tuaj yeem txhim kho cov tshuaj tua kab mob thiab cov nyhuv tshiab ntawm cov khoom noj roj dej.Piv txwv li, qhov sib ntxiv ntawm cov txiv laum huab xeeb tuaj yeem txuas ntxiv lub neej txee, thiab cov nyhuv antioxidant yog plaub npaug ntawm lwm yam;qhov sib ntxiv ntawm cov hnyuv ntxwm qhuav cov khoom lag luam tuaj yeem tiv thaiv cov khoom hloov pauv;qhov sib ntxiv ntawm cov zaub mov kib thiab instant noodles tuaj yeem txuas ntxiv lub txee lub neej thiab tiv thaiv nws.Daim ntawv thov kev lag luam: 1. antioxidant rau roj hmab thiab yas kev lag luam 2. PVC additive (anti-fisheye agent) 3. nws yog siv rau cov tshuaj intermediate thiab organic synthesis 4. stabilizer (Stabilizer): tiv thaiv resin ester thiab lwm yam khoom los ntawm kev ua pa oxygen .
Raws li cov kev cai ntawm Tuam Tshoj tus GB2760-1996 cov qauv kev noj qab haus huv rau kev siv cov khoom noj khoom haus additives (04.007), tert-butyl hydroquinone TBHQ tuaj yeem siv los ua antioxidant hauv cov roj noj, cov khoom noj kib, cov khoom ntses qhuav, biscuits, instant noodles, ceev- boiled mov, kaus poom qhuav txiv hmab txiv ntoo thiab pickled nqaij khoom.Feem ntau, qhov pom zoo noj yog 0.01 ~ 0.02% ntawm tag nrho cov roj thiab cov rog, nrog rau qhov ntau npaum li cas ntawm 0.2 g / kg.Yuav siv tau rau hauv tshuaj pleev ib ce.
Ncaj nraim kom sov cov roj rau 35 ~ 60 ℃, ntxiv TBHQ raws li qhov xav tau kev faib ua feem, do nruj nreem rau 10 ~ 15 feeb kom yaj nws, thiab tom qab ntawd txuas ntxiv do (tsis tas yuav ua kom muaj zog kom tsis txhob muaj cua ntau dhau los) rau kwv yees li 20 feeb los xyuas kom meej qhov kev faib tawm ntawm TBHQ.Noob txoj kev: ua ntej, TBHQ yog kiag li yaj nyob rau hauv ib tug me me npaum li cas ntawm cov roj los yog 95% cawv tov los npaj 5-10% TBHQ roj los yog dej cawv tov, thiab ces ncaj qha los yog los ntawm kev ntxiv rau hauv cov roj los yog roj nrog ib meter, stirring thiab faib nws tusyees.Pumping method Lub TBHQ concentrated tov npaj los ntawm cov noob txoj kev yog txhaj rau hauv lub raj xa dej nrog cov roj ruaj khov los yog roj nrog cov nqi ntws ruaj khov thiab cov nqi ntws los ntawm cov twj tso kua mis stainless hlau ntau raws li qhov sib piv.Xyuas kom tseeb tias muaj kev kub ntxhov txaus hauv lub raj xa dej kom ua T
European Food Safety Agency (EFSA) thiab US Food and Drug Administration (FDA) tau txiav txim siab tias kev siv tert-butyl hydroquinone nyob rau hauv ib tug tej yam concentration yog kev nyab xeeb rau tib neeg lub cev.FDA txwv nws qhov sib ntxiv rau cov roj thiab cov rog rau 0.02%.Hauv kev sim, kev noj ntau dua ntawm tert-butyl hydroquinone ua rau cov tsiaj sim ua kom pom cov qog nqaij hlav hauv plab thiab DNA puas.Ib txoj kev tshawb fawb tau pom tias qhov ntev ntev ntawm qhov muaj ntau ntawm TBHQ tuaj yeem ua rau mob qog noj ntshav, tshwj xeeb tshaj yog mob qog noj ntshav.Txawm li cas los xij, lwm cov kev tshawb fawb tau los sib txawv.Piv txwv li, phenolic antioxidants xws li TBHQ tuaj yeem cuam tshuam cov carcinogenesis ntawm polycyclic amines (TBHQ yog ib qho ntawm lawv, tsis yog ib qho zoo).EFSA kuj ntseeg tias TBHQ yuav tsis ua rau mob qog noj ntshav.Ib daim ntawv luam tawm xyoo 1986 ntseeg tias los ntawm qhov kev xav ntawm ntau npaum li cas, muaj cov npoo loj ntawm qhov tso cai ntawm TBHQ thiab qhov kev puas tsuaj rau cov tsiaj sim.
