Application
Dehydroacetic acid is an intermediate of organic synthesis, a toughening agent and a broad spectrum food preservative. Since it was found to have antibacterial properties in 1940, it has been paid attention to by many countries and has been allowed to be used for food preservation. As a food additive, dehydroacetic acid is allowed to be used in cheese, butter, margarine, refreshing drinks, fermented milk and lactobacillus drinks, bean paste, stuffing, etc. Sodium dehydroacetate is commonly used as a food additive. The product is also used in daily cosmetics, fiber products, medicine (such as the treatment of ringworm), and dental materials anticorrosion.
