Description

Sodium Diacetate CAS NO 126-96-5 is a versatile, free-flowing white powder that functions as a highly effective acidulant, flavoring agent, and antimicrobial preservative. Its primary commercial value lies in its dual-action capability, providing controlled acidity and mold inhibition in a single, easy-to-handle compound. This product is essential for manufacturers in the food, feed, and industrial sectors seeking reliable, multi-functional ingredients to enhance product safety, shelf life, and process efficiency.

Application

• Food Preservation & Acidulation: Widely used in baked goods (bread, tortillas), snack foods, and meat products to inhibit mold and bacterial growth while imparting a tangy flavor.
• Animal Feed & Silage Additive: Acts as a preservative and mold inhibitor in animal feed and silage to prevent spoilage and maintain nutritional quality.
• Flavor Enhancer: Employed in seasoning blends, vinegar powders, and snack coatings to provide a sharp, acetic acid taste.
• Industrial Biocide: Used in various industrial applications, including adhesives and textiles, to prevent microbial degradation.
• pH Control Agent: Utilized in chemical processes and product formulations where precise, buffered acidity is required.
