Ayyuka:
Sodium Metabisulfite shine ƙarin abincin da aka saba amfani dashi. Baya ga tasirin bleaching, shima yana da ayyuka masu zuwa:
1) Tasirin Anti Browning
Enzymatic Browning yakan faru ne a cikin fruitsa fruitsan itace, dankali, Sodium Metabisulfite wakili ne mai ragewa, aikin polyphenol oxidase yana da tasiri mai hanawa, 0,0001% na sulfur dioxide na iya rage 20% na aikin enzyme, 0.001% na sulfur dioxide na iya hana shi gaba daya aikin enzyme, na iya hana Browning enzymatic; Bugu da kari, zai iya cinye oxygen a cikin kayan abinci kuma ya taka rawar deoxygenation. Sulfite a cikin ƙarin aiki tare da glucose, hana glucose cikin abinci da amino acid glycoammonia dauki, don haka yana da tasirin anti Browning.
2) Tasirin Antiseptic
Sulfurous acid na iya taka rawar mai kiyaye sinadarin acid, sinadarin sulfurous acid da ba a rarrabuwa ya yi amannar zai hana yisti, mould, kwayoyin cuta.Rahoton da aka raba yana da karfi sau 1000 fiye da bisulfite wajen hana E. coli. Yana da sau 100-500 da karfi yisti na giya kuma sau 100 sunfi ƙarfi don tsarawa. Lokacin da sulfur dioxide ya kasance acidic, yana da tasiri mai ƙarfi akan ɗaukar ƙwayoyin cuta.

Za'a iya amfani dashi azaman abubuwan haɗin waken na kwance.
3) Tasirin Antioxidant.
Sulfite yana da tasirin maye mai ban sha'awa Saboda sulfurous acid wakili ne mai ƙarfi, zai iya cinye oxygen a cikin ƙungiyar 'ya'yan itace da kayan lambu, ya hana aikin oxidase, lalata iskar shaka na bitamin C wajen hana' ya'yan itace da kayan lambu yana da matukar tasiri.
Hanyar aikin sodium metabisulfite:
Bleach dangane da yanayin aikinta ana iya kasu kashi biyu: Gwanin Oxidation da Rage Bleach.Sodium metabisulfite wakili ne mai rage jini.
Sodium metabisulfite ana iya yin amfani da shi ta hanyar rage launin launin fata.Wannan launi na mafi yawan mahaukatan sunadaran ana samun su ne daga kungiyoyin chromaticity da ke cikin kwayoyin su.Kungiyoyin kalar gashi suna dauke da hadaddun da ba a kammala ba, rage fitowar kwayar atam din bilicin na iya sanya rukunin launi mai gashi wanda yake dauke a cikin hadadden hadadden ruwan guda bond, kwayoyin halitta zai rasa launi. Wasu abincin Browning yana faruwa ne saboda kasancewar ions masu kuzari, ƙara ƙarancin bleach na iya sanya ions mai ƙwari cikin ions mai ƙwari, hana abincin Kaza.
Sodium metabisulfite ana yin daskararwa ta hanyar kari na sulfites. Anthocyanin da sukari za a iya zubar da su ta hanyar karin haske. Wannan aikin yana iya canzawa, kuma ana iya cire sinadarin sulfurous ta hanyar dumama ko kuma sanya shi a ciki, don haka za'a iya sabunta anthocyanin kuma za'a iya dawo da jan launi na asali.
A cikin masana'antar biskit, ana amfani da sodium metabisulfite azaman mai inganta biskit. Kafin amfani dashi, an shirya shi zuwa kashi 20%, sannan sai a sanya shi a cikin kullu mara ƙamshi a cikin lokuta daban-daban yayin aiwatar da kullu.Saboda sulphur dioxide da sodium pyrosulphate ya fitar yayin aiwatar da kullu, ƙarfi da taurin garin alkama suna da ɗan girma, kuma ƙaramin adadin ƙari na iya hana lalacewar kayayyakin biskit saboda ƙarfin da ya wuce kima.

Abubuwan kulawa don amfani da sodium metabisulfite:
Ya kamata a lura da waɗannan maki yayin amfani da sodium metabisulfite a cikin abincin da aka sarrafa:
1) sodium metabisulfite reductive bleaching agent, maganinta bashi da karko da kuma canzawa, yanzu ana amfani dashi, don hana rashin kwanciyar hankali da kuma jujjuyawar iska.
2) lokacin da akwai ions na ƙarfe a cikin abinci, ragowar sulfite za a iya yin oxidized; Hakanan zai iya haifar da raguwar canza launin launin fata, ta yadda zai rage tasirin ruwan hoda .Saboda haka, ana amfani da masu yin ƙarfe na ƙarfe yayin samarwa.
3) amfani da sinadarin bleaching na sulfite, saboda bacewar sulfur dioxide da launi mai sauki, don haka yawanci a cikin ragowar abincin da ya wuce sulphur dioxide, amma ragowar adadin ba zai wuce misali
4) Sulfuric acid ba zai iya dakatar da aikin pectinase ba, wanda zai lalata haɗin pectin.Bugu da ƙari, shigar sinadarin sulfurous cikin ƙwayar 'ya'yan itace, sarrafa ɓauren' ya'yan itace, don cire duk sulfur dioxide, don haka 'ya'yan itacen ya kiyaye su sulfurous acid kawai ya dace da yin jam, 'ya'yan itace busasshe, ruwan inabi mai' ya'yan itace, 'ya'yan itacen candied, ba za a iya amfani da shi azaman albarkatun kasa na gwangwani ba.
5) Sulfites na iya lalata thiamine, saboda haka ba abu bane mai sauƙi a cikin abincin kifi. 6) Sulfites suna da saukin amsa tare da aldehydes, ketones, sunadarai, da dai sauransu.
