Sodium Diacetate Preservative

Sodium diacetate is a salt made from acetic acid, a common food ingredient also found in vinegar. It is produced by combining sodium hydroxide or sodium carbonate with acetic acid. This process results in a white crystalline powder that can help control acidity and preserve food.

Manufacturers use sodium diacetate as a preservative and flavoring agent, particularly for its ability to inhibit the growth of bacteria and mold. It is often found in baked goods like cakes and cupcakes, as well as in prepared foods such as wraps and burritos, where it can add a tangy, vinegar-like flavor.

In the United States, sodium diacetate is generally recognized as safe (GRAS) by the FDA for use as a food additive. International bodies like JECFA have evaluated it. Evidence does not suggest adverse health effects at the levels typically consumed in food. Some studies have explored its potential antimicrobial properties, but it is not considered a significant health concern for most people.
