O le DMDC o lo'o fa'aaogaina lautele i sua suamalie ma o lona tekinolosi e matua'i matua.O le faʻamaʻiina o le DMDC i le sua suamalie e aʻafia i le ituaiga ma le mamafa o le sua o fualaau aina, ma o le tuʻufaʻatasia o le faʻaogaina o le DMDC ma isi tekinolosi faʻamaʻi e mafai ona faʻaleleia atili ai le faʻamaʻiina.
Dimethyl Dicarbonate (DMDC) o se vai e leai ni lanu ma sina manogi manogi.E fa'aaoga muamua e fai ma mea e fa'asao ai meainu, fesoasoani mo le fa'agaioiina, po'o fa'ama'i (Numera 242).Ole fa'aogaina ole DMDC e aoga tele pe a mana'omia ona fa'amama le uaina ae e le mafai ona fa'amama fa'amama, fa'asa'o, po'o le sulfur.O lo'o fa'aaogaina fo'i le DMDC e fa'amautu ai meainu e le o ni 'ava malosi e pei o meainu suamalie po'o vai inu suamalie, mea inu ta'aloga isotonic, lauti aisa, ma vai fa'afefe.
E mafai e le DMDC ona ulu i totonu o le sela sela ma fegalegaleai ma enzymes i microorganisms e poloka ai le metabolism, ma maua ai le aʻafiaga o le bactericidal.E oo lava i le maualalo o fa'atonuga, e mafai e le DMDC ona fa'amae'a fa'aumatia siama masani o mea inu e aunoa ma le a'afiaina o le tofo, tofo ma le lanu o le meainu.E le gata i lea, o le DMDC e mafai ona fa'avavevave ma fa'ato'a fa'asusuina e su'e le aofa'i o le carbon dioxide ma le methanol i meainu.O se mea fa'anatura fo'i lea i le sua o fualaau 'aina.
E mafai ona fa'aogaina le Dimethyl Dicarbonate i meainu fa'asao, vai inu suamalie po'o mea inu suamalie, mea inu lauti, mea inu isobaric ma le tele o isi meainu.I Europa, Amerika ma isi atunuu, o le dimethyl dicarbonate ua faʻamaonia mo le faʻaaogaina lautele i meainu eseese.O le Komiti Faʻapitoa a le Faʻalapotopotoga o le Soifua Maloloina a le Lalolagi i meaʻai faaopoopo, le European Food Science Committee ma le United States Food and Drug Administration-o nisi o pulega taua na tuʻuina atu pepa e faʻamaonia ai le saogalemu o talosaga dimethyl = carbonate.Fa'afefete fa'afefete;fa'asao.
Fa'amama malūlū o ituaiga meainu nei: meainu suamalie, meainu malosi (fa'atasi pe leai fo'i le carbon dioxide), meainu lauti (fa'atasi pe leai fo'i le carbon dioxide), meainu sua suamalie (fa'atasi pe leai fo'i le carbon dioxide, sua suamalie i totonu i le 100% ).
E i ai a'afiaga leaga i mata ma pa'u, manava sa'o po'o le 'ai oona.Fa'ataga e fa'aoga (e mafai ona fa'aoga e fai ma fungicide malulu mo meainu i lalo ole GMP, fa'atasi ai ma le maualuga maualuga ole 250mg/L; FAO/WHO,2001).
