Sodium diacetate is a 1:1 mixture of sodium acetate and acetic acid, is commonly used as a preservative and acidulant. Structurally, sodium diacetate has up to 41wt% acetic acid locked in its crystalline state, hence the name “dry acetic acid”. As a solid acid, sodium diacetate is effective as a fungicide, bactericide, anti-mold, and anti-rope. In agro-industry, it is routinely used to preserve the quality of feeds during storage.
