Products Description of Dehydroacetic acid CAS#520-45-6

DHA is widely found in many deep-sea fish oils, as well as in marine algae and some terrestrial plants. DHA is an ω-3 type unsaturated fatty acid and an essential fatty acid for the body. mp44℃. It is very unstable to light, oxygen and heat, and is easily oxidized and cracked, so antioxidants should usually be added. Lecithin, dextrose, cyclodextrin or inert gas can also be added to improve the stability of the preparation.

Product Application of Dehydroacetic acid CAS#520-45-6

Dehydroacetic acid is an organic synthesis intermediate, a toughening agent, and a broad-spectrum food preservative. Since its antibacterial properties were discovered in 1940, it has been recognized by many countries and has been allowed to be used in food preservation. As a food additive, dehydroacetic acid is allowed to be used in cheese, butter, margarine, soft drinks, fermented milk and lactic acid bacteria drinks, bean paste, stuffings, etc. Sodium dehydroacetate is generally used as a food additive. This product is also used in daily cosmetics, fiber products, medicines (such as the treatment of ringworm), and the preservation of dental materials.
