| Questions and Answers (Q&A) | Back Directory | [Description]
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.
