What is Sodium dehydroacetate?

 With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Sodium dehydroacetate which has developed particularly rapidly in recent years. Do you know about Sodium dehydroacetate?


The official answer:Sodium dehydroacetate, also known as sodium dehydroacetate, with the molecular formula C8H7NaO4, is the sodium salt of dehydroacetic acid. It is a white or nearly white crystalline powder, non-toxic, odourless, easily soluble in water, glycerol, propylene glycol, slightly soluble in ethanol and acetone, light and heat resistant, used as a preservative, antiseptic insecticide and food additive.

What’s the application of Sodium dehydroacetate?

Sodium dehydroacetate is an antibacterial agent with high safety, wide antibacterial range and high antibacterial capacity. It is less affected by the acidity or alkalinity in the food, and can maintain efficient antimicrobial efficacy under acidic or slightly alkaline Chemicalbook sexual conditions. Its antibacterial ability is better than sodium benzoate, potassium sorbate, calcium propionate, etc. It is an ideal preservative for food preservation.
