Sodium dehydroacetate Chemische Eigenschaften,Einsatz,Produktion Methoden

  • R-Sätze Betriebsanweisung: R22:Gesundheitsschädlich beim Verschlucken.
  • Beschreibung Sodium dehydroacetate is the sodium salt of dehydroacetate. It is mainly used as a new generation food preservative and food additive, being used extensively in sauce, fruit, bread, cake, moon cake, margarine and beverage. Sodium dehydroacetate (DHA-S) has a wide spectrum of antimicrobial activity that accounts for its use in cosmetic products as a preservative and antimicrobial agent. It is effective in the treatment of both bacteria and fungi. It is also a kind of anticoagulant agent through depleting the blood level of vitamin K.
  • Chemische Eigenschaften White to yellowish powder
  • Verwenden Dehydroacetic acid sodium salt (DHS-Na) is used in the food industry as preservative for fruits, vegetables, fruit juice, honey, beer, milk, protein and fat products; in human and veterinary medicine as bactericide and fungicide. Product Data Sheet
