DMDC inoshandiswa zvakanyanya mujusi yemuchero uye tekinoroji yayo yakura.The sterilization effect yeDMDC mumuto wemichero inokonzerwa nemhando uye kuomeswa kwejusi yemichero, uye kushandiswa kwakasanganiswa kweDMDC nemamwe matekinoroji ekuita sterilization kunogona kuvandudza zvakanyanya mhedzisiro.
Dimethyl Dicarbonate (DMDC) imvura isina ruvara uye inonhuwira zvishoma.Inonyanya kushandiswa sechinwiwa chekuchengetedza, kugadzirisa rubatsiro, kana sterilant (Nhamba 242).Kushandiswa kweDMDC kunonyanya kubatsira kana waini ichida kucheneswa asi isingakwanise kucheneswa, kuita pasteurized, kana sulfured.DMDC inoshandiswawo kudzikamisa zvinwiwa zvisiri zvinodhaka senge carbonated or non-carbonated juice drinks, isotonic sports drinks, iced teas, uye mvura ine flavored.
DMDC inogona kupinda musero membrane uye kudyidzana nema enzymes mune tupukanana kuvhara metabolism, nokudaro kuwana bactericidal effect.Kunyangwe pakadzika zvakanyanya, DMDC inogona kuuraya chinwiwa chinoparadza mabhakitiriya pasina kukanganisa kuravira, kuravira uye ruvara rwechinwiwa.Pamusoro pezvo, DMDC inogona kukurumidza uye yakanyatsogadziriswa hydrolyzed kutsvaga huwandu hwecarbon dioxide uye methanol muzvinwiwa.Ichi zvakare chigadziro chechisikigo mumuchero wemuchero.
Dimethyl Dicarbonate inogona kushandiswa mu carbonated zvinwiwa, aerated kana kwete-aerated muchero muto zvinwiwa, tii zvinwiwa, isobaric zvinwiwa uye zvimwe zvinwiwa zvakawanda.MuEurope, United States nedzimwe nyika, dimethyl dicarbonate inotenderwa kushandiswa kwakapararira muzvinwiwa zvakasiyana.Sangano reWorld Health Organisation's Joint Expert Committee on Food Additives, European Food Science Committee neUnited States Food and Drug Administration-zvimwe zviremera zvakakosha zvakaburitsa magwaro anoratidza kuchengetedzwa kwedimethyl = carbonate application.Yeast inhibitor;kuchengetedza.
Cold sterilization yemhando dzinotevera dzezvinwiwa: zvinwiwa zvine muchero, zvinwiwa zvine simba rakawanda (ine kana isina kabhoni dhaikisaidhi), zvinwiwa zvetii (ine kana isina carbon dioxide), zvinwiwa zvemichero yemuchero (ine kana isina carbon dioxide, muto wemichero unosvika 100% )
Iine corrosive effect pameso uye paganda, yakananga inhaled kana kumwiwa muchetura.Inobvumirwa kushandisa (inogona kushandiswa sechando fungicide yezvinwiwa pasi pemamiriro eGMP, ine huwandu hwakanyanya hwe250mg/L; FAO/WHO,2001).
