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

Sodium dehydroacetate yog ib hom hmoov dawb uas yooj yim yaj hauv dej. Nws muaj cov kua qaub tsis muaj zog hauv dej thiab tuaj yeem tso tawm SO2 roj hauv qab cov kua qaub. Sodium dehydroacetate yog ib qho tshuaj tiv thaiv kab mob rau cov khoom noj uas muaj ntau yam thiab muaj zog heev, nrog rau lub peev xwm tiv thaiv pwm thiab poov xab. Nrog tib koob tshuaj, cov nyhuv tiv thaiv kab mob yog ntau zaus lossis txawm tias kaum npaug ntau dua li cov sodium benzoate thiab potassium sorbate uas siv dav dav. Qhov tseem ceeb tshwj xeeb yog tias nws muaj cov nyhuv tiv thaiv me ntsis rau cov kab mob tsim kua qaub, tshwj xeeb tshaj yog cov kab mob lactic acid.
