I-Dimethyl Dicarbonate (DMPC; i-Velcorin) (i-CAS: 4525-33-1), eyaziwa nangokuthi i-Viguolin, iwuhlobo lwesilondolozi sesiphuzo sejusi yezithelo (i-INS No. 242) evunyelwe ukuthi isetshenziswe kumazinga ezwe lami wokusebenzisa izithasiselo zokudla.Ngaphansi kwezimo zokushisa ezivamile noma eziphansi, i-DMDC inamandla anamandla okubulala amabhaktheriya amaningi angcolisayo eziphuzweni zejusi yezithelo, futhi umphumela wayo we-antiseptic uhlobene eduze nokuguqulwa nokungasebenzi kwamaprotheni abalulekile e-enzyme kubhaktheriya yi-DMDC.Uma kuqhathaniswa nobunye ubuchwepheshe bokuvala inzalo ngokomzimba, ukusetshenziswa kwe-DMDC kunezindleko eziphansi, kulula futhi kuphephile ukusebenza, futhi akuthinti ukunambitheka, iphunga nombala womkhiqizo.Kube ngenye yezindawo ezishisayo ocwaningweni lobuchwepheshe obusafufusa bokuvala inzalo okungashisi ukushisa.
| Isigaba Sokudla No. | Ukudla Isigaba | Izinga eliphezulu (g/kg) | Qaphela |
| 14.02.03 | Isiphuzo sezithelo nemifino (umpe). | 0.25 | |
| 14.04 | Iziphuzo ze-Carbonated 0.25 | ||
| 14.05.01 | Iziphuzo zetiye | 0.25 | |
| 14.08 | Iziphuzo ezinambithekayo (iziphuzo ezine-flavour yezithelo kuphela) | 0.25 | |
| 14.09 | Ezinye iziphuzo (kuphela eziphuzweni ezingenatshwala ezivutshelwe i-malt) | 0.25 |
I-DMDC isetshenziswa kakhulu kujusi yezithelo futhi ubuchwepheshe bayo sebuvuthiwe.Umphumela wokuvala inzalo we-DMDC kujusi yezithelo uthintwa uhlobo nohlobo lwejusi yesithelo, futhi ukusetshenziswa okuhlangene kwe-DMDC nobunye ubuchwepheshe bokuvala inzalo kungathuthukisa kakhulu umphumela wokuvala inzalo.
I-Dimethyl Dicarbonate (DMDC) iwuketshezi olungenambala olunephunga elimnandi kancane.Ngokuyinhloko isetshenziswa njengesilondolozi sesiphuzo, insiza yokucubungula, noma i-sterilant (Inombolo 242).Ukusetshenziswa kwe-DMDC kuwusizo ikakhulukazi lapho iwayini lidinga ukuvalwa inzalo kodwa lingenakuhluzwa obala, lifakwe i-pasteurized, noma lifakwe nesibabule.I-DMDC iphinde isetshenziselwe ukuzinzisa iziphuzo ezingezona ezidakayo ezifana neziphuzo zejusi ezine-carbonated noma ezingenaso i-carbonated, iziphuzo zezemidlalo ze-isotonic, ama-iced teas, namanzi anongiwe.
I-DMDC ingangena ulwelwesi lweseli futhi ihlanganyele nama-enzyme kuma-microorganisms ukuvimbela imetabolism, ngaleyo ndlela izuze umphumela we-bactericidal.Ngisho nasezimweni eziphansi kakhulu, i-DMDC ingabulala ngempumelelo amagciwane amosha isiphuzo ngaphandle kokuthinta ukunambitheka, ukunambitheka nombala wesiphuzo.Ukwengeza, i-DMDC ingafakwa ngokushesha nangokuphelele i-hydrolyzed ukuze ilandele amanani e-carbon dioxide ne-methanol eziphuzweni.Lokhu futhi kuyisithako semvelo kujusi yezithelo.
I-Dimethyl Dicarbonate ingasetshenziswa eziphuzweni ze-carbonated, iziphuzo zejusi yezithelo ezinomoya noma ezingenayo umoya, iziphuzo zetiye, iziphuzo ze-isobaric nezinye iziphuzo eziningi.EYurophu, e-United States nakwamanye amazwe, i-dimethyl dicarbonate ivunyelwe ukusetshenziswa kabanzi eziphuzweni ezihlukahlukene.IKomidi Elihlanganyelwe Lochwepheshe Benhlangano Yezempilo Yezwe Lonke Lezithako Zokudla, IKomiti Yesayensi Yezokudla YaseYurophu kanye Nokuphathwa Kwezokudla Nezidakamizwa zase-United States-ezinye iziphathimandla ezibalulekile zikhiphe imibhalo efakazela ukuphepha kwezicelo ze-dimethyl = carbonate.I-yeast inhibitor;isilondolozi.
Ukuvala inzalo okubandayo kwalezi zinhlobo zeziphuzo ezilandelayo: iziphuzo ezinezithelo, iziphuzo ezinamandla kakhulu (ezinayo noma ngaphandle kwe-carbon dioxide), iziphuzo zetiye (ezinayo noma ngaphandle kwe-carbon dioxide), iziphuzo zejusi yezithelo (ezine-carbon dioxide noma ngaphandle kwayo, okuqukethwe kwejusi yesithelo kufika ku-100% ).
Inomthelela olimazayo emehlweni nasesikhumbeni, ehogelwe ngokuqondile noma emukelwe njengobuthi.Kuvunyelwe ukusetshenziswa (kungasetshenziswa njengesibulala-sikhunta esibandayo esiphuzweni esingaphansi kwezimo ze-GMP, esinesilinganiso esiphezulu esingu-250mg/L;FAO/WHO,2001).
Ukuvutha;ukubola okushisayo kwegesi evuselelayo enobuthi nesibabayo.
