Sodium metabisulphite (Na₂S₂O₅), tseem hu ua sodium pyrosulfite, yog cov hmoov dawb crystalline dav siv thoob plaws kev lag luam rau nws cov khoom khaws cia thiab antioxidant. Pom tau tias yog E223 hauv European Union, qhov sib xyaw no ua lub luag haujlwm tseem ceeb hauv kev khaws zaub mov, kev kho dej, thiab lwm yam, txawm tias yuav tsum tau ua tib zoo tuav vim nws qhov tshwm sim.
Sodium metabisulphite muaj ob lub sodium ions thiab disulfite anion (S₂O₅²⁻). Nws zoo nkaus li dawb, dawb-ntws hmoov nrog pungent sulfur dioxide (SO₂) tsw. Nws yog soluble hauv dej heev, tsim sodium bisulfite (NaHSO₃), thiab decomposes ntawm 150 ° C, tso SO₂ roj. Nws cov tshuaj acidic ua raws li tus neeg sawv cev muaj zog.
Daim ntawv thov:
1. Khoom noj khoom haus kev lag luam:
●Preservative nyob rau hauv cov txiv hmab txiv ntoo qhuav, wines, thiab cov zaub mov tiav los inhibit microbial kev loj hlob thiab oxidation.
● Tiv thaiv kom tsis txhob muaj cov piam thaj hauv cov zaub thiab txiv hmab txiv ntoo.
2.Winemaking:
●Sanitizes cov cuab yeej thiab stabilizes yuav tsum los ntawm neutralizing pliaj kab mob thiab cov poov xab.
3. Kev kho dej:
●Neutralizes chlorine thiab ua raws li cov tshuaj tua kab mob hauv cov dej khib nyiab.
4.Photography: Cov khoom tsim los txhim kho cov duab los ntawm kev tshem tawm cov nyiaj ntau dhau.
5.Cosmetics: Preservative nyob rau hauv cov tshuaj pleev ib ce thiab plaub hau khoom kom ntev lub neej txee.
Kev nyab xeeb thiab tuav:
● Kev phom sij rau kev noj qab haus huv: tso tawm SO₂ thaum ntsib cov kua qaub lossis dej noo, ua rau muaj kev phom sij ua pa. Sulfite-sensitive cov neeg tuaj yeem ntsib kev tsis haum tshuaj.
● Kev Tiv Thaiv: Siv hnab looj tes, tsom iav, thiab qhov ncauj qhov ntswg; xyuas kom qhov cua. Khaws kom deb ntawm cov kua qaub thiab oxidizers.
● Kev Pab Ua Ntej: Yaug qhov chaw raug dej; nrhiav kev pab kho mob kom nqus tau los yog noj.
