DMDC tau siv dav hauv cov kua txiv hmab txiv ntoo thiab nws cov cuab yeej siv tau zoo heev.Kev ua kom tsis muaj menyuam ntawm DMDC hauv cov kua txiv hmab txiv ntoo yog cuam tshuam los ntawm hom thiab hom ntawm cov kua txiv hmab txiv ntoo, thiab kev sib xyaw ua ke ntawm DMDC thiab lwm yam sterilization technologies tuaj yeem txhim kho kom tsis muaj menyuam.
Dimethyl Dicarbonate (DMDC) yog cov kua xim tsis muaj xim nrog ib qho me ntsis pungent aroma.Nws feem ntau yog siv los ua dej haus preservative, kev pab cuam, los yog sterilant (Enumber 242).Daim ntawv thov ntawm DMDC yog qhov tshwj xeeb tshaj yog thaum caw yuav tsum tau ua kom tsis muaj menyuam tab sis tsis tuaj yeem ua kom tsis muaj menyuam lim, pasteurized, lossis sulfur.DMDC kuj tseem siv los tswj cov dej tsis muaj cawv xws li cov dej haus carbonated lossis cov dej tsis muaj carbonated, dej haus isotonic kis las, iced teas, thiab dej tsw qab.
DMDC tuaj yeem nkag mus rau cell membrane thiab cuam tshuam nrog cov enzymes hauv cov kab mob los thaiv cov metabolism, yog li ua tiav cov kab mob bactericidal.Txawm tias muaj tsawg heev, DMDC tuaj yeem tua cov kab mob ua rau haus dej tsis zoo yam tsis muaj kev cuam tshuam rau saj, tsw thiab xim ntawm cov dej haus.Tsis tas li ntawd, DMDC tuaj yeem ua tau sai thiab ua tiav hydrolyzed kom taug qab cov pa roj carbon dioxide thiab methanol hauv cov dej haus.Qhov no kuj yog ib yam khoom muaj nyob rau hauv cov kua txiv hmab txiv ntoo.
Dimethyl Dicarbonate tuaj yeem siv rau hauv cov dej haus carbonated, aerated los yog tsis-aerated txiv hmab txiv ntoo dej haus, tshuaj yej haus, dej haus isobaric thiab ntau lwm yam dej haus.Hauv Tebchaws Europe, Tebchaws Meskas thiab qee lub tebchaws, dimethyl dicarbonate tau pom zoo rau kev siv dav hauv ntau yam dej haus.Lub Koom Haum Ntiaj Teb Kev Noj Qab Haus Huv Koom Tes Pawg Kws Tshaj Lij Tshaj Lij rau Khoom Noj Ntxiv, European Food Science Committee thiab United States Food and Drug Administration-qee cov tub ceev xwm tseem ceeb tau tshaj tawm cov ntaub ntawv pov thawj kev nyab xeeb ntawm dimethyl = carbonate daim ntawv thov.Cov poov xab inhibitor;khaws cia.
Kev ua kom tsis muaj menyuam txias ntawm cov dej haus hauv qab no: dej haus txiv hmab txiv ntoo, dej haus muaj zog (nrog lossis tsis muaj carbon dioxide), dej tshuaj yej (nrog lossis tsis muaj carbon dioxide), cov kua txiv hmab txiv ntoo (nrog lossis tsis muaj carbon dioxide, cov kua txiv hmab txiv ntoo muaj 100% ).
Muaj cov nyhuv corrosive rau ntawm qhov muag thiab tawv nqaij, ncaj qha nqus los yog noj tshuaj lom.Tso cai siv (tuaj yeem siv los ua cov tshuaj tua kab mob khaub thuas rau cov dej haus raws li GMP, nrog rau qhov siab tshaj plaws ntawm 250mg / L; FAO / WHO, 2001).
Flammability;thermal decomposition ntawm tshuaj lom thiab ntsim stimulating roj.
