What is Sodium Diacetate?

Sodium diacetate is a versatile compound used in food and feed as a mildew inhibitor, acidulant, and enhancer, characterized by its stable properties and cost-effectiveness. It appears as white crystals with the aroma of acetic acid, readily absorbing moisture and highly soluble in water. Approved as safe by the US FDA, it functions effectively in preventing mold, preserving freshness, enhancing taste, boosting nutritional value, and promoting growth in livestock and poultry feed.

Its production typically involves the reaction of acetic acid with sodium hydroxide to yield sodium acetate, followed by crystallization to obtain sodium diacetate.

Sodium Diacetate has a wide range of uses

1. Anti-mold

1.Sodium diacetate is mainly antibacterial through the release of single molecule acetic acid when dissolved in water. The released single molecule acetic acid can penetrate the cell wall of mold, enter the microorganism, interfere with the interaction of enzymes, denature the intracellular protein, and inhibit the growth and reproduction of mold. It has a good effect on green Trichoderma, Listeria, Rhizopus and Aspergillus flavus.

2. Anticorrosion

Sodium diacetate has a certain preservation effect, which can prevent food from being invaded by various microorganisms during long-term storage, inhibit the survival, growth and reproduction of microorganisms, and prevent food from spoiling.

3. Improve the taste of food

Sodium diacetate can be used as an acidulant to add specific flavors to food, balance the taste of food, stimulate the taste buds, make the food taste more delicious, and improve the taste of food overall.

4. Disinfection

Due to its unique chemical properties and anti-microbial growth mechanism, sodium diacetate’s components can penetrate the cell wall of microorganisms to denature them, achieving the effect of disinfection and antibacterial.

User asked question:

Q: Q: What are the characteristics of sodium diacetate in terms of anti-mold effect?
A: 1. Its anti-mold and anti-corrosion effects surpass those of benzoates. 2. The sour taste is soft, overcoming the irritating smell unique to propionates.
3. Its applications are extensive, spanning anti-mold and anti-corrosion measures in diverse foods. Moreover, it finds widespread usage in pharmaceuticals, tobacco, papermaking, fruit preservation, feed, and other sectors.
4. Its application methods are convenient and adaptable, allowing for direct addition, spraying, or dipping.
5. It preserves the original characteristics of food without being influenced by the food’s pH. It actively participates in human metabolism, producing CO2 and H2O, and integrates seamlessly into food, maintaining its original color, aroma, and nutritional profile.
