Sodium diacetate (NaH)C4H7NaO4 is a highly effective preservative and acidity
regulator widely used in the food and feed
industries. It is a white, crystalline powder with a characteristic
vinegar-like smell due to its acetic acid component. Sodium
diacetate is well known for its antimicrobial properties, pH regulation,
and flavor enhancement, making it a key ingredient in
food preservation and animal nutrition.

Applications
1. Food Industry Applications
Sodium diacetate is widely used in the food industry for preservation, flavor enhancement, and pH regulation:
1. Preservative in Bakery Products – Extends the shelf life of bread and pastries by preventing mold growth.
2. Antimicrobial Agent in Meat Products – Inhibits bacterial growth, particularly against Listeria and Salmonella, ensuring food safety.
3. pH Regulator in Seasonings & Sauces – Maintains acidity levels in salad dressings, sauces, and condiments.4. Flavor Enhancer in Snacks – Used in chips and processed foods to provide a tangy, vinegar-like taste.
5. Dough Conditioner – Improves dough elasticity and texture in baking applications.
2. Feed Industry Applications
Sodium diacetate is also beneficial in animal feed as a preservative and dietary supplement:
1. Mold Inhibitor in Animal Feed – Prevents fungal growth and feed spoilage.
2. pH Buffer in Livestock Diets – Helps regulate stomach acidity in ruminants and pigs.
3. Appetite Enhancer for Poultry & Swine – Improves feed palatability, increasing feed intake.
4. Growth Promoter for Aquaculture – Enhances digestive efficiency in fish and shrimp.
5. Ketosis Prevention in Dairy Cows – Supports metabolic health and milk production.
