I-Dimethyl Dicarbonate (i-DMPC; i-Velcorin) (i-CAS: i-4525-33-1), eyaziwa nangokuthi i-Viguolin, luhlobo oluthile lwesiselo se-juice yeziqhamo (i-INS No. 242) evumelekileyo ukuba isetyenziswe kwimigangatho yokutya yelizwe lam.Ngaphantsi kweemeko eziqhelekileyo okanye eziphantsi kweqondo lokushisa, i-DMDC inamandla amakhulu okubulala iibhaktheriya ezininzi ezingcolileyo kwiziphuzo zejusi yeziqhamo, kwaye umphumo wayo we-antiseptic uhambelana ngokusondeleyo nokuguqulwa kunye nokungasebenzi kweeprotheni eziphambili ze-enzyme kwiibhaktheriya yi-DMDC.Xa kuthelekiswa nobunye ubuchwepheshe bokwenza inzala emzimbeni, ukusetyenziswa kwe-DMDC kuphantsi kweendleko, kulula kwaye kukhuselekile ukusebenza, kwaye akuchaphazeli incasa, ivumba kunye nombala wemveliso.Ibe yenye yezona ndawo ziphambili kuphando lwetekhnoloji ezisakhulayo zokuvala inzala.
| Udidi Lokutya Nomb. | Udidi lokutya | Inqanaba eliphezulu (g/kg) | Phawula |
| 14.02.03 | Isiselo seziqhamo kunye nemifuno (i-nectar). | 0.25 | |
| 14.04 | Iziselo zekhabhoni 0.25 | ||
| 14.05.01 | Iziselo zeti | 0.25 | |
| 14.08 | Iziselo ezinencasa (iziselo ezinencasa yeziqhamo kuphela) | 0.25 | |
| 14.09 | Ezinye iziselo (kuphela kwimalt ebilisiweyo kwiziselo ezingezizo utywala) | 0.25 |
I-DMDC isetyenziswa kakhulu kwijusi yeziqhamo kwaye ubuchwephesha bayo bukhulile noko.Isiphumo sokuvala inzala kwe-DMDC kwijusi yeziqhamo ichatshazelwa luhlobo kunye noxinzelelo lwejusi yeziqhamo, kwaye ukusetyenziswa okudityanisiweyo kwe-DMDC kunye nobunye ubuchwephesha bokuvala inzala kunokuphucula kakhulu umphumo wokuvala inzala.
I-Dimethyl Dicarbonate (DMDC) lulwelo olungenambala kunye nevumba elimnandi kancinane.Ngokuyintloko isetyenziselwa isiselo esinxilisayo, i-processing aid, okanye i-sterilant (Inombolo 242).Ukusetyenziswa kwe-DMDC kuluncedo ngakumbi xa iwayini ifuna ukucocwa kodwa ingenako ukuhluzwa okungenantsholongwane, kufakwe i-pasteurized, okanye i-sulfured.I-DMDC ikwasetyenziselwa ukuzinzisa iziselo ezingezizo ezinxilisayo ezifana neziselo zejusi zekhabhoni okanye ezingezizo iikhabhoni, iziselo zezemidlalo ze-isotonic, iti ekhenkcezayo, kunye namanzi anencasa.
I-DMDC inokungena kwi-membrane yeseli kwaye idibanise ne-enzymes kwii-microorganisms ukuthintela imetabolism, ngaloo ndlela ifezekise umphumo we-bactericidal.Nokuba kugxininiso oluphantsi kakhulu, i-DMDC inokubulala ngokufanelekileyo iibhaktheriya ezitshabalalisa isiselo ngaphandle kokuchaphazela incasa, incasa kunye nombala wesiselo.Ukongeza, i-DMDC inokukhawuleza kwaye ifakwe i-hydrolyzed ngokupheleleyo ukulandelela izixa ze-carbon dioxide kunye ne-methanol kwiziselo.Oku kukwasisithako sendalo kwincindi yeziqhamo.
I-Dimethyl Dicarbonate ingasetyenziselwa iziselo ze-carbonated, i-aerated okanye i-non-aerated fruit juice drinks, i-tea drinks, i-isobaric kunye nezinye iziselo ezininzi.EYurophu, eUnited States nakwamanye amazwe, idimethyl dicarbonate ivunyiwe ukuba isetyenziswe ngokubanzi kwiziselo ezahlukeneyo.I-World Health Organisation's Joint Expert Expert Committee on Food Additives, iKomiti yeSayensi yoKutya yaseYurophu kunye ne-United States yoLawulo lokuTya kunye neDrugs-amanye amagunya abalulekileyo akhuphe amaxwebhu abonisa ukhuseleko lwe-dimethyl = izicelo ze-carbonate.I-Yeast inhibitor;isilondolozi.
Ukuvala iziselo ezibandayo kwezi ntlobo zilandelayo zeziselo: iziselo ezineziqhamo, iziselo ezinamandla kakhulu (ezinekharbon okanye ngaphandle kwayo), iziselo zeti (ezinekharbon okanye ngaphandle kwecarbon dioxide), iziselo zejusi yeziqhamo (ezinekharbon okanye ngaphandle kwekharbon diokside, isiselo sejusi yeziqhamo ukuya kwi-100% ).
Unefuthe elonakalisayo emehlweni kunye nolusu, oluphefumle ngokuthe ngqo okanye oluyityhefu.Kuvunyelwe ukusebenzisa (inokusetyenziswa njenge-fungicide ebandayo kwiziselo phantsi kweemeko ze-GMP, kunye noxinzelelo olukhulu lwe-250mg / L; FAO / WHO,2001).
Ukutsha;ukubola thermal yegesi eyityhefu kunye neziqholo evuselelayo.
