tert-Butylhydroquinone (TBHQ) (CAS: 1948-33-0),I-antioxidant esebenzayo kakhulu.Ekutyeni, i-tert-Butylhydroquinone isetyenziswa njenge-antioxidant kwi-oyile yemifuno kunye neentlobo zeoli yezilwanyana ezidliwayo.Ayitshintshi umbala xa ifakwe kwi-iron, kwaye ayitshintshi incasa okanye ivumba lokutya.Isenokusetyenziswa kunye nezinye izithinteli ezifana ne-butyl hydroxyanisole (BHA).Ikhowudi yayo ye-E njengesongezo sokutya yi-E319.Isetyenziswa kakhulu ekutyeni kuba inokwandisa ubomi bayo beshelufu.Kwimveliso yoshishino, ingasetyenziselwa ukuzinzisa ukuthintela i-self-polymerization ye-peroxides ye-organic.Isenokongezwa kwakhona kwi-biofuel njenge-agent anti-corrosion.Kwiziqholo, i-TBHQ ingasetyenziselwa ukulungiswa, ukuvimbela ukuguquguquka kunye nokuphucula ukuzinza.Ukongezelela, isetyenziselwa iipende, i-varnishes kunye ne-resins.
i-tert-Butylhydroquinone (TBHQ) (i-CAS: 1948-33-0), inokusebenza okuphezulu kwe-antioxidant kunye ne-antioxidant enamandla kune-BHT, i-BHA, i-PG (i-acrylic gallate) kunye ne-vitamin e.Inokuthintela ngempumelelo ukukhula kwe-Bacillus subtilis, i-Staphylococcus aureus, i-Escherichia coli, i-pneumococcus kunye nezinye iibhaktheriya, kunye ne-Aspergillus niger, i-Aspergillus variegata, i-Aspergillus flavus kunye nezinye ii-microorganisms.Umsebenzi we-antioxidant we-TBHQ ungcono kakhulu kune-antioxidants eqhelekileyo.Ngokubhekiselele kwioli yemifuno, amandla e-antioxidant alandelayo: TBHQ> PG> BHT> BHA.Ukongeza i-TBHQ ekudleni akukwazi nje ukulibazisa ukuwohloka kwe-oxidative yeoli kunye namafutha, kodwa kunqande iindidi ze-microorganisms.Ingasetyenziswa njenge-antioxidant kumafutha atyiwayo, ukutya okuqhotsiweyo, iimveliso zentlanzi ezomisiweyo, iibhiskithi, i-noodles ekhawulezileyo, irayisi ebilisiwe ngokukhawuleza, iziqhamo ezomisiweyo ezinkonkxiweyo, iimveliso zenyama ezivundiweyo, kwaye zinokusetyenziswa nakwizithambiso.① TBHQ Antioxidants.Ifanelekile kwioli ekrwada kunye neoli engapheliyo, njengeoli yejongilanga.Ukupheka ioli kunye nemveliso ebhaka, kufuneka idibaniswe ne-BHA, kodwa ifanelekile kwimveliso ebilisiwe kunye neyosiweyo.Umthamo jikelele ngu-100 ~ 200 mg / kg.ukuvavanywa kwezongezo zeoli yokutya.Inokuthintela i-oxidation yeeoli ezininzi, iiplastiki, irabha, njl njl. Intsimbi kunye nobhedu azitshintshi umbala, kodwa ukuba kukho i-alkali, inokujika ipinki.Ukuxhathisa okugqwesileyo kwe-oxidation.Ii-Antioxidants.I-Tert-butyl hydroquinone ilungele i-oyile ekrwada kunye ne-oyile engaxutywanga kakhulu, njenge-oyile kajongilanga.Ukupheka ioli kunye nemveliso ebhaka, kufuneka idibaniswe ne-BHA, kodwa ifanelekile kwimveliso ebilisiwe kunye neyosiweyo.Umthamo jikelele ngu-100 ~ 200 mg / kg.Isetyenziswa njenge-PVC ye-anti-fish eye-eye agent kunye nesongezo sokutya, njenge-antioxidant, kwaye ingasetyenziselwa ioli etyiwayo, ukutya okuqhotsiweyo, iibhiskithi, ii-noodles ezikhawulezayo, irayisi ephekiweyo kwangoko, iziqhamo ezomisiweyo ezinkonkxiweyo, iimveliso zentlanzi ezomisiweyo kunye neemveliso zenyama enyangisiweyo. ukusetyenziswa okuphezulu kwe-0.2 g / kg.
I-tert-Butylhydroquinone (TBHQ) (i-CAS: i-1948-33-0) i-antioxidant ekhuselekileyo kunye nesebenzayo kwi-oyile edliwayo kunye namafutha, afanelekileyo kwioli yemifuno, i-lard, njl.Le mveliso ikwanayo ne-anti-bacterial, i-mold kunye ne-yeast effects, enokuthi ikhulise i-antiseptic kunye ne-fresh-reeping effect yokutya okunamafutha aphezulu.Ngokomzekelo, ukongezwa kweoli ye-peanut kunokwandisa kakhulu ubomi beshelufu, kwaye umphumo we-antioxidant uphindwe kane kunezinye iintlobo;ukongezwa kweemveliso ze-sausage ezomisiweyo zentlanzi kunokuthintela imveliso ekutshintsheni;ukongezwa kokutya okuqhotsiweyo kunye ne-noodles ekhawulezileyo kunokwandisa kakhulu ubomi beshelufu kunye nokukhusela.Ukusetyenziswa kwezoshishino: 1. i-antioxidant ye-rubber kunye ne-plastiki yoshishino 2. I-PVC yokongeza (i-anti-fisheye agent) 3. isetyenziselwa i-pharmaceutical intermediate and organic synthesis 4. i-stabilizer (i-Stabilizer): thintela i-resin ester kunye nezinye izinto ezibangelwa yi-oxygen. .
Ngokutsho kwemimiselo ye-GB2760-1996 yaseTshayina yemigangatho yezempilo yokusetyenziswa kwezongezo zokutya (04.007), i-tert-butyl hydroquinone TBHQ ingasetyenziswa njenge-antioxidant kwi-oyile edliwayo, ukutya okuqhotsiweyo, iimveliso zeentlanzi ezomisiweyo, iibhiskithi, i-noodles ngokukhawuleza, ngokukhawuleza- irayisi ebilisiwe, iziqhamo ezomisiweyo ezinkonkxiweyo kunye neemveliso zenyama ezikhethiweyo.ngokubanzi, idosi ecetyiswayo yi-0.01 ~ 0.02% yexabiso elipheleleyo leoli kunye namafutha, kunye ne-dosage ephezulu ye-0.2 g / kg.Inokusetyenziswa kwizinto zokuthambisa.
Ukutshisa ngokuthe ngqo igrisi ukuya kwi-35 ~ 60 ℃, yongeza i-TBHQ ngokomlinganiselo ofunekayo, ugxobhoze ngamandla kwimizuzu eyi-10 ~ 15 ukuyinyibilikisa, uze uqhubeke uvuselela (akufuneki uvuselele ngamandla ukukhusela umoya omkhulu ukuba ungene) malunga nemizuzu ye-20 ukuqinisekisa ukuhanjiswa okufanayo kwe-TBHQ.Indlela yembewu: okokuqala, i-TBHQ ichithwa ngokupheleleyo kwixabiso elincinci leoli okanye i-95% isisombululo sotywala ukulungiselela i-5-10% ye-TBHQ ioli okanye isisombululo sotywala, kwaye emva koko ngokuthe ngqo okanye ngokuyongeza kwi-fat okanye i-oyile ngemitha, ivuselela kwaye ukusasaza ngokulinganayo.Indlela yokumpompa Isisombululo esigxininisiweyo se-TBHQ esilungiselelwe yindlela yembewu ifakwe kumbhobho ngamafutha azinzileyo okanye i-oyile enesantya esisisigxina sokuhamba kunye nesantya sokuhamba ngempompo yobungakanani bensimbi engenasici ngokomlinganiselo ochaziweyo.Qinisekisa ukuba kukho isiphithiphithi esaneleyo kumbhobho ukwenza i-T
I-arhente yokhuseleko lokutya yaseYurophu (i-EFSA) kunye nolawulo lwe-US lokutya kunye neziyobisi (FDA) lugqibe ukuba ukusetyenziswa kwe-tert-butyl hydroquinone ngaphakathi koxinzelelo oluthile kukhuselekile kumzimba womntu.I-FDA ikhawulela ukongezwa kwayo kwiioli ezidliwayo kunye namafutha kwi-0.02%.Kuvavanyo, ukuthathwa kokugxilwa okuphezulu kwe-tert-butyl hydroquinone kubangele ukuba izilwanyana zovavanyo zibonise iimpawu zamathumba esiswini kunye nomonakalo weDNA.Uthotho lwezifundo lubonise ukuba ukuba sesichengeni ixesha elide kwizigxina eziphezulu ze-TBHQ kunokubangela umhlaza, ngakumbi umhlaza wesisu.Nangona kunjalo, ezinye izifundo ziye zafikelela kwizigqibo ezahlukeneyo.Ngokomzekelo, i-phenolic antioxidants efana ne-TBHQ inokuthintela i-carcinogenesis ye-polycyclic amines (i-TBHQ yenye yazo, ingeyiyo esebenzayo).I-EFSA ikwakholelwa ukuba i-TBHQ ayisayi kubangela umhlaza.Iphepha elipapashwe kwi-1986 likholelwa ukuba ngokombono we-dosage, kukho umda omkhulu phakathi kwexabiso elivumelekileyo le-TBHQ kunye nenani lomonakalo kwizilwanyana zokulinga.
Ukubola kobushushu kukhupha umsi oyityhefu kunye nerhasi.
