    The main application of Sodium Diacetate
    • Sodium diacetate in food and beverages functions as a preservative, inhibiting the growth of mold, yeast, and bacteria by controlling acidity levels. It is commonly applied in baked goods, cheeses, dressings, and juices.
    • Sodium diacetate in meat is commonly used as an effective preservative to inhibit microbial growth and prevent spoilage.
    • Sodium diacetate in pharmaceuticals serves as an excipient to adjust and maintain the pH balance of drugs, vitamins, and supplements, ensuring their stability. It also acts as a wetting and solubilizing agent, aiding in the dissolution of drug particles.
    • Sodium diacetate in animal nutrition acts as an acidity regulator, lowering pH to optimize feed digestion and nutrient absorption.
    • Sodium diacetate in leather processing is utilized to neutralize acidity during preparatory steps like soaking, liming, and tanning. It assists in leather preparation for dyeing by modifying the pH.
    • As an important application, sodium diacetate uses in the manufacture of azo dyes and other synthetic colorants to assist in uniform color formation and hue reliability.
