i-tert-Butylhydroquinone (TBHQ) (CAS: 1948-33-0),iyi-antioxidant esebenza kahle kakhulu.Ekudleni, i-tert-Butylhydroquinone isetshenziswa njenge-antioxidant emafutheni emifino kanye nezinhlobonhlobo zamafutha ezilwane adliwayo.Ayishintshi umbala lapho ibekwe okusansimbi, futhi ayishintshi ukunambitheka noma iphunga lokudla.Ingasetshenziswa futhi nezinye izivimbelakuvunda ezifana ne-butyl hydroxyanisole (BHA).Ikhodi yayo ye-E njengesithasiselo sokudla ngu-E319.Isetshenziswa kakhulu ekudleni ngoba inganweba isikhathi sayo sokuphila.Emkhiqizweni wezimboni, ingasetshenziswa njenge-stabilizer ukuvimbela i-self-polymerization yama-peroxides e-organic.Ingase futhi yengezwe ku-biofuel njenge-ejenti evimbela ukugqwala.Kumakha, i-TBHQ ingasetshenziswa njengendlela yokulungisa, evimbela ukuguquguquka nokuthuthukisa ukuzinza.Ngaphezu kwalokho, ibuye isetshenziswe kumapende, ama-varnishes nama-resin.
I-tert-Butylhydroquinone (TBHQ) (i-CAS: 1948-33-0), inokusebenza okuphezulu kwe-antioxidant namandla anamandla okulwa ne-antioxidant kune-BHT, i-BHA, i-PG (i-acrylic gallate) ne-vitamin e.Ingakwazi ukuvimbela ngempumelelo ukukhula kwe-Bacillus subtilis, i-Staphylococcus aureus, i-Escherichia coli, i-pneumococcus namanye amagciwane, kanye ne-Aspergillus niger, i-Aspergillus variegata, i-Aspergillus flavus nezinye izinambuzane.Umsebenzi we-antioxidant we-TBHQ ungcono kakhulu kunowe-antioxidant evamile.Mayelana nowoyela wemifino, amandla e-antioxidant ami kanje: TBHQ > PG > BHT> BHA.Ukwengeza i-TBHQ ekudleni akukwazi nje ukubambezela ukuwohloka kwe-oxidative yamafutha namafutha, kodwa futhi kuvimbela izinhlobonhlobo zama-microorganisms.Ingasetshenziswa njenge-antioxidant emafutheni adliwayo, ukudla okuthosiwe, imikhiqizo yezinhlanzi ezomisiwe, amabhisikidi, ama-noodle asheshayo, irayisi elibilisiwe ngokushesha, izithelo ezomisiwe ezifakwe ethini, imikhiqizo yenyama efakwe emanzini anosawoti, futhi ingasetshenziswa nasezintweni zokugcoba.① I-TBHQ Antioxidants.Ifanele uwoyela ongahluziwe kanye namafutha angagcwele kakhulu, njengamafutha kabhekilanga.Ngamafutha okupheka nemikhiqizo ebhakiwe, kufanele ihlanganiswe ne-BHA, kodwa ifanele imikhiqizo ebilisiwe neyothosiwe.Umthamo ojwayelekile ngu-100 ~ 200 mg/kg.ukuhlolwa kwezithasiselo zamafutha okudla.Ingavimbela i-oxidation yamafutha amaningi, amapulasitiki, irabha, njll. I-Iron nethusi akushintshi umbala, kodwa uma kukhona i-alkali, ingaba pink.Ukumelana okuhle kwe-oxidation.Ama-Antioxidants.I-Tert-butyl hydroquinone ifanele uwoyela ongahluziwe namafutha angagcwele kakhulu, njengamafutha kabhekilanga.Ngamafutha okupheka nemikhiqizo ebhakiwe, kufanele ihlanganiswe ne-BHA, kodwa ifanele imikhiqizo ebilisiwe neyothosiwe.Umthamo ojwayelekile ngu-100 ~ 200 mg/kg.Isetshenziswa njenge-PVC anti-fish eye agent kanye nesengezo sokudla, njenge-antioxidant, futhi ingasetshenziselwa amafutha adliwayo, ukudla okuthosiwe, amabhisikidi, ama-noodle asheshayo, irayisi eliphekwe ngokushesha, izithelo ezomisiwe ethinini, imikhiqizo yezinhlanzi ezomisiwe kanye nemikhiqizo yenyama ephulukisiwe. ukusetshenziswa okuphezulu kwe-0.2 g/kg.
I-tert-Butylhydroquinone (TBHQ) (i-CAS: 1948-33-0) i-antioxidant ephephile futhi ephumelelayo yamafutha adliwayo namafutha, ifanele amafutha emifino, isinqumelo, njll. Ifaneleka ngokukhethekile ukuthosa ukudla ngenxa yezinga eliphezulu lokuncibilika kanye nendawo yokubilisa.Lo mkhiqizo futhi unemiphumela emihle yokulwa namagciwane, isikhunta kanye nemvubelo, engathuthukisa umphumela we-antiseptic kanye nokugcina okusha kokudla okunamafutha aphezulu.Isibonelo, ukungezwa kwamafutha e-peanut kungandisa kakhulu impilo yeshalofu, futhi umphumela we-antioxidant uphindwe kane kunezinye izinhlobo;ukwengezwa kwemikhiqizo yezinhlanzi ezomisiwe zesoseji kungavimbela umkhiqizo ekushintsheni;ukwengezwa kokudla okuthosiwe nama-noodle asheshayo kungandisa kakhulu impilo yeshalofu futhi kuvimbele.Ukufakwa kwezimboni: 1. i-antioxidant embonini yenjoloba neyepulasitiki 2. Isengezo se-PVC (i-anti-fisheye agent) 3. isetshenziselwa ukwakhiwa kwemithi okuphakathi kanye ne-organic 4. i-stabilizer (Stabilizer): vimbela i-resin ester nezinye izinto ukuthi zingabangelwa umoya-mpilo .
Ngokwezinhlinzeko ze-GB2760-1996 yaseChina yezindinganiso zezempilo zokusetshenziswa kwezithasiselo zokudla (04.007), i-tert-butyl hydroquinone TBHQ ingasetshenziswa njenge-antioxidant emafutheni adliwayo, ukudla okuthosiwe, imikhiqizo yezinhlanzi ezomisiwe, amabhisikidi, ama-noodle asheshayo,- irayisi elibilisiwe, izithelo ezomisiwe ethinini kanye nemikhiqizo yenyama efakwe emanzini anosawoti.ngokuvamile, isilinganiso esinconywayo singu-0.01~0.02% yenani eliphelele lamafutha namafutha, nesilinganiso esiphezulu esingu-0.2 g/kg.Kungasetshenziswa izimonyo.
Shisisa amafutha abe ku-35 ~ 60 ℃, engeza i-TBHQ ngokwesilinganiso esidingekayo, ugovuze ngamandla imizuzu eyi-10 ~ 15 ukuze uyincibilikise, bese uqhubeka ugoqa (akudingeki ugovuze ngamandla ukuze uvimbele ukungena komoya omningi) cishe imizuzu engama-20 ukuze kuqinisekiswe ukusatshalaliswa okufanayo kwe-TBHQ.Indlela yembewu: okokuqala, i-TBHQ incibilika ngokuphelele enanini elincane lamafutha noma isixazululo sotshwala esingu-95% ukulungisa i-5-10% ye-TBHQ yamafutha noma isisombululo sotshwala, bese ngokuqondile noma ngokuyifaka emafutheni noma emafutheni ngemitha, ivuselela futhi. ukuyisabalalisa ngokulinganayo.Indlela yokumpompa Isixazululo esigxilisiwe se-TBHQ esilungiselelwe indlela yembewu sijovwa epayipini ngamafutha azinzile noma uwoyela onesilinganiso esinqunyiwe sokugeleza kanye nezinga lokugeleza ngepompo yobuningi bensimbi engagqwali ngokwesilinganiso esishiwo.Qiniseka ukuthi kuneziyaluyalu ezanele epayipini lokwenza i-T
I-ejensi yokuphepha kokudla yase-Europe (i-EFSA) kanye nokuphathwa kokudla nezidakamizwa kwase-US (i-FDA) banqume ukuthi ukusetshenziswa kwe-tert-butyl hydroquinone ngaphakathi kokugxiliswa okuthile kuphephile emzimbeni womuntu.I-FDA ikhawulela ukwengezwa kwayo emafutheni adliwayo namafutha ku-0.02%.Ocwaningweni, ukuthathwa kokugxila okuphezulu kwe-tert-butyl hydroquinone kubangele izilwane zokuhlola ukuthi zibonise izimpawu zamathumba esisu kanye nokulimala kwe-DNA.Uchungechunge lwezifundo lubonise ukuthi ukuchayeka isikhathi eside ekugxilweni okuphezulu kwe-TBHQ kungase kubangele umdlavuza, ikakhulukazi umdlavuza wesisu.Nokho, ezinye izifundo ziye zafinyelela eziphethweni ezihlukile.Isibonelo, ama-antioxidants e-phenolic afana ne-TBHQ angavimbela i-carcinogenesis ye-polycyclic amines (i-TBHQ ingenye yazo, hhayi ephumelelayo).I-EFSA ikholelwa nokuthi i-TBHQ ngeke iwubangele umdlavuza.Iphepha elanyatheliswa ngo-1986 lalikholelwa ukuthi ngokombono womthamo, kunomkhawulo omkhulu phakathi kwenani elivumelekile le-TBHQ kanye nenani lomonakalo ezilwaneni ezihlolwayo.
Ukubola okushisayo kukhipha intuthu enobuthi nephunga.
