Dimethyl Dicarbonate (DMPC; Velcorin) (CAS: 4525-33-1), sidoo kale loo yaqaan Viguolin, waa nooc ka mid ah cabitaanka cabitaanka casiirka khudradda (INS No. 242) kaas oo loo oggol yahay in lagu isticmaalo heerarka isticmaalka cuntada lagu daro ee dalkayga.Xaaladaha heerkulka caadiga ah ama xitaa hooseeya, DMDC waxay leedahay awood xooggan oo ay ku disho bakteeriyada wasakhaysan ee cabitaannada casiirka miraha, iyo saameynteeda jeermiska waxay si dhow ula xiriirtaa beddelka iyo firfircoonida borotiinnada enzyme muhiimka ah ee bakteeriyada DMDC.Marka la barbar dhigo tignoolajiyada kale ee jeermiska jidhka, isticmaalka DMDC waa mid qiimo jaban, fudud oo badbaado leh in lagu shaqeeyo, oo ma saamayso dhadhanka, urta iyo midabka alaabta.Waxay noqotay mid ka mid ah meelaha ugu kulul ee cilmi baarista tikniyoolajiyada jeermis-dilista ee soo ifbaxaya.
| Qaybta Cuntada | Qaybta cuntada | Heerka ugu sarreeya (g/kg) | Ogow |
| 14.02.03 | Casiirka khudradda iyo khudradda (nectar) cabbitaanka | 0.25 | |
| 14.04 | Cabbitaannada kaarboonka ah 0.25 | ||
| 14.05.01 | Cabbitaannada shaaha | 0.25 | |
| 14.08 | Cabbitaannada dhadhanka leh (cabitaannada dhadhanka miraha leh oo keliya) | 0.25 | |
| 14.09 | Cabbitaannada kale (kaliya ee cabitaannada aan khamriga ahayn ee khamiirka leh) | 0.25 |
DMDC waxaa si weyn loogu isticmaalaa casiirka khudaarta iyo tignoolajiyadadeedu waa qaangaar.Saamaynta jeermiska ee DMDC ee casiirka khudradda waxaa saameeya nooca iyo cadaadiska casiirka khudradda, iyo isticmaalka isku-dhafka ah ee DMDC iyo tiknoolajiyada kale ee jeermiska ayaa si weyn u wanaajin kara saameynta jeermiska.
Dimethyl Dicarbonate (DMDC) waa dareere aan midab lahayn oo leh caraf yar.Waxa ugu horrayn loo istcimaalaa sida kaydinta cabitaanka, gargaarka farsamaynta, ama nadiifinta (Tirada 242).Codsiga DMDC ayaa si gaar ah faa'iido u leh marka khamriga loo baahan yahay in la nadiifiyo laakiin aan la nadiifin karin, la pasteurized, ama baaruud la saari karin.DMDC sidoo kale waxaa loo isticmaalaa in lagu dejiyo cabitaanada aan khamriga ahayn sida cabitaanada casiirka kaarboon ku jira ama kuwa aan kaarboonaysnayn, cabitaannada isboortiga isotonic, shaaha barafaysan, iyo biyaha dhadhanka leh.
DMDC waxay geli kartaa xuubka unugga waxayna la falgeli kartaa enzymes-ka noolaha si ay u xannibaan dheef-shiid kiimikaadka, sidaas darteed waxay ku gaari kartaa saameynta bakteeriyada.Xataa marka ay aad u yar tahay, DMDC waxay si wax ku ool ah u dili kartaa bakteeriyada caadiga ah ee kharriba cabitaanka iyada oo aan saamayn ku yeelan dhadhanka, dhadhanka iyo midabka cabitaanka.Intaa waxaa dheer, DMDC si degdeg ah iyo gebi ahaanba biyo-dhir baa loo samayn karaa si loo raadiyo qaddarka kaarboon laba ogsaydh iyo methanol ee cabitaannada.Tani sidoo kale waa qayb dabiici ah oo ku jirta casiirka khudradda.
Dimethyl Dicarbonate waxaa loo isticmaali karaa cabitaannada kaarboonka leh, cabitaannada casiirka miraha la shiday ama kuwa aan hawada lagu shubin, cabitaannada shaaha, cabitaannada isobaric iyo cabitaanno kale oo badan.Yurub, Maraykanka iyo qaar ka mid ah wadamada kale, dimethyl dicarbonate ayaa loo oggolaaday isticmaalka baahsan ee cabitaanada kala duwan.Guddiga Khabiirka Wadajirka ah ee Ururka Caafimaadka Adduunka ee Ku-darka Cunnada, Guddiga Sayniska Cunnada Yurub iyo Maamulka Cuntada iyo Dawooyinka ee Mareykanka-qaar ka mid ah mas'uuliyiinta muhiimka ah ayaa soo saaray dukumentiyo caddaynaya badbaadada dimethyl = codsiyada carbonate.Xakamaynta khamiirka;ilaaliye.
Madhalayska qabow ee noocyada cabitaannada soo socda: Cabbitaannada miraha leh, cabitaannada tamarta sare leh (oo leh ama aan lahayn kaarboon dioxide), cabitaannada shaaha (oo leh ama aan lahayn kaarboon laba ogsaydh), cabitaannada casiirka khudradda (oo leh ama aan lahayn kaarboon laba ogsaydh, casiirka khudradda ilaa 100% ).
Waxay saameyn xun ku leedahay indhaha iyo maqaarka, si toos ah loo nuugo ama sun loo nuugo.La oggol yahay in la isticmaalo (waxaa loo isticmaali karaa sidii fungicide qabow ee cabitaannada hoos yimaada xaaladaha GMP, oo leh ugu badnaan 250mg/L; FAO/WHO,2001).
