Sodium Diacetate is a molecular compound formed from sodium acetate and acetic acid, typically in a 1:1 ratio. It is widely recognized as a safe, effective, and economical food additive that functions both as a preservative and a flavoring agent. With a mild vinegar-like aroma, it delivers both antimicrobial protection and a pleasant acidic note, particularly in savory and baked products.
As a GRAS-approved ingredient, Sodium Diacetate is commonly used in baked goods, tortillas, snack seasonings, cured meats, sauces, and spice blends. It is especially valued for its ability to inhibit the growth of mold, yeast, and bacteria — including Listeria monocytogenes — making it a powerful tool for extending product shelf life and ensuring food safety.
Sodium Diacetate is highly stable and easy to apply. It can be added directly to dry mixes, brines, or applied as a surface treatment. In bakery applications, it helps prevent mold growth in bread and cakes without affecting dough structure. In meat and poultry, it is often used in combination with lactates or diacetates to improve microbial stability and reduce sodium nitrite usage.
This ingredient is effective at relatively low usage levels, typically ranging from 0.1% to 0.3%, depending on the product matrix and local regulations. It is heat-stable and maintains its efficacy during baking or cooking processes. In snack seasonings, it also enhances the tangy, savory profile expected in products like barbecue chips or vinegar-flavored crisps.
