Menene Sodium Dehydroacetate CAS 4418-26-2?

Sodium dehydroacetate wani farin crystalline foda ne mai sauƙi mai narkewa a cikin ruwa. Yana nuna raunin acidity a cikin ruwa kuma yana iya sakin iskar SO2 a ƙarƙashin yanayin acidic. Sodium dehydroacetate babban nau'i ne mai fa'ida kuma mai kiyaye abinci sosai na kashe ƙwayoyin cuta, tare da ƙarfin hanawa musamman akan mold da yisti. A daidai wannan sashi, tasirin antibacterial sau da yawa ko ma sau goma fiye da sodium benzoate da potassium sorbate. Abin da ke da mahimmanci shi ne cewa yana da ƙananan tasirin hanawa akan kwayoyin samar da acid, musamman kwayoyin lactic acid.
