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. | [CAS DataBase Reference]

| [Agricultural Uses]
Fungicide, Bactericide: Sodium diacetate is a fungicide and bactericide registered to control molds and bacteria, thereby preventing spoilage in stored grains. The pesticide is applied to hay as a dust or soluble concentrate (liquid spray) during the baling process. It is applied to silage as a fermentation "aid" to preserve the quality of field corn, alfalfa, sorghum, oats and grasses, stored in silos. Sodium diacetate is composed of acetic acid and sodium acetate. It dissociates to acetate, sodium and hydrogen ions, normal components of plants and animals, and of human foods. Acetates are formed in living organisms during the metabolism of food. Acetates and acetic acid have long been used in both human and animal foods, without significant adverse effects. Sodium diacetate is also used as an antimicrobial agent in baked goods and other foods, and in medicine and cosmetics manufacturing as a freshener, flavoring and pH regulator.
