Sodium Dehydroacetate CAS 4418-26-2 yog dab tsi?

Sodium dehydroacetate yog dawb crystalline hmoov uas yooj yim soluble hauv dej. Nws nthuav tawm cov acidity tsis muaj zog hauv dej thiab tuaj yeem tso cov pa roj SO2 hauv cov kua qaub. Sodium dehydroacetate yog ib qho dav-spectrum thiab muaj tshuaj tua kab mob zoo heev, nrog tshwj xeeb muaj zog inhibitory muaj peev xwm tiv thaiv pwm thiab cov poov xab. Nyob rau tib lub koob tshuaj, cov nyhuv tshuaj tua kab mob yog ob peb zaug lossis txawm tias kaum tawm lub sijhawm siab dua li cov siv dav siv sodium benzoate thiab potassium sorbate. Dab tsi yog qhov tseem ceeb yog tias nws muaj kev cuam tshuam me ntsis ntawm cov kua qaub tsim cov kab mob, tshwj xeeb tshaj yog cov kab mob lactic acid.
