Useful:

• Uses: Acetic acid in solid form; sequestrant; food preservative to inhibit molds and rope-forming bacteria in bread: Glabe, Food Ind. 14, no. 2, 46 (1942). Sodium acetate buffer solution has been used for the precipitation of DNA. It has also been used as a component of supporting electrolyte for electrochemical sensor. Sodium Diacetate is a preservative, sequestrant, acidulant, and fla- voring agent that is a molecular compound of sodium acetate and acetic acid which yields acetic acid. it is a white crystalline powder which is hygroscopic. it functions against mold and bacteria and is used in bread. it is also termed sodium hydrogen diacetate.
