Yintoni i-Sodium Dehydroacetate CAS 4418-26-2?

I-sodium dehydroacetate ngumgubo omhlophe wekristale onyibilika lula emanzini. Ibonisa i-asidi ebuthathaka emanzini kwaye inokukhulula igesi ye-SO2 phantsi kweemeko ze-acidic. I-sodium dehydroacetate yindawo ebanzi kunye nesigcinakaliso sokutya esilwa neebhaktiriya, esinamandla okuthintela umngundo kunye negwele. Kwidosi enye, impembelelo ye-antibacterial ngamaxesha amaninzi okanye amashumi amaxesha aphezulu kune-benzoate ye-sodium esetyenziswa ngokubanzi kunye ne-potassium sorbate. Eyona nto ibaluleke kakhulu kukuba inefuthe elincinci lokuthintela kwiibhaktheriya ezivelisa i-asidi, ngakumbi i-lactic acid bacteria.

Isicelo

I-1.I-sodium dehydroacetate yi-agent ye-antibacterial enokhuseleko oluphezulu, uluhlu olubanzi lwe-antibacterial, kunye nekhono elinamandla lokulwa ne-antibacterial. Ayichatshazelwa kancinci yi-acidity okanye i-alkalinity yokutya kwaye inokugcina ukusebenza okuphezulu kwe-antibacterial phantsi kweemeko ze-acidic okanye i-alkaline encinci. Ikhono layo lokulwa ne-antibacterial liphezulu kune-sodium benzoate, i-potassium sorbate, i-calcium propionate, njl., okwenza kube yinto efanelekileyo yokugcina ukutya.
2. I-sodium dehydroacetate ingasetyenziselwa ukunyanga umphezulu wesinyithi, ukwehlisa, kunye nokuthintela umhlwa kwimigangatho yesinyithi,
3. I-sodium dehydroacetate ingasetyenziselwa uhlalutyo lweekhemikhali kunye nokulungiswa kwee-mordants.
I-4.I-sodium dehydroacetate iphinda isetyenziswe kwiinkalo zokwenza iphepha, isikhumba, iingubo, izithambiso, njl.
