Yintoni iSodium Dehydroacetate CAS 4418-26-2?

I-Sodium dehydroacetate yipowder emhlophe ekristale enyibilikayo lula emanzini. Ibonisa i-asidi ebuthathaka emanzini kwaye inokukhupha igesi ye-SO2 phantsi kweemeko ze-asidi. I-Sodium dehydroacetate sisigcini-kutya esibanzi nesilwa neentsholongwane ezininzi, esinamandla okuthintela ukungunda kunye nemvubelo. Kwidosi efanayo, isiphumo se-antibacterial siphindwe kaninzi okanye kalishumi ngaphezu kwe-sodium benzoate kunye ne-potassium sorbate esetyenziswa kakhulu. Okubaluleke kakhulu kukuba ayinampembelelo ingako yokuthintela kwiibhaktheriya ezivelisa i-asidi, ngakumbi iibhaktheriya ze-lactic acid.

Isicelo

1. I-sodium dehydroacetate sisithako esilwa neentsholongwane esikhuselekileyo kakhulu, sibanzi kwaye sinamandla okulwa neentsholongwane. Ayichaphazeleki kakhulu yi-acidity okanye i-alkalinity yokutya kwaye inokugcina ukusebenza okuphezulu kwe-antibacterial phantsi kweemeko ze-acidic okanye ze-alkaline kancinci. Amandla ayo okulwa neentsholongwane angaphezulu kwe-sodium benzoate, i-potassium sorbate, i-calcium propionate, njl.njl., nto leyo eyenza ukuba ibe sisixhobo esifanelekileyo sokutya.
2. I-Sodium dehydroacetate ingasetyenziselwa unyango lomphezulu wesinyithi, ukususa amafutha, kunye nokuthintela umhlwa kwiindawo zesinyithi,
3. I-sodium dehydroacetate ingasetyenziselwa uhlalutyo lweekhemikhali kunye nokulungiselela ii-mordants.
4. I-sodium dehydroacetate ikwasetyenziswa kwicandelo lokwenza iphepha, ulusu, ukugquma, izinto zokuthambisa, njl.
