E262i - Acétate de sodium

Origin

Sodium acetate (E262i) is the sodium salt of acetic acid. It can be produced through the reaction of acetic acid with sodium carbonate or sodium hydroxide. Industrially, it is often produced as a byproduct of other chemical processes. It is a readily available and relatively inexpensive chemical compound.

Usage

Sodium acetate has diverse applications in the food industry. It functions primarily as a preservative, buffering agent, and flavoring agent. As a preservative, it inhibits the growth of bacteria and fungi, extending the shelf life of food products. It is commonly used in processed meats, snacks, sauces, and pickled products. As a buffering agent, it helps to maintain a stable pH level, preventing undesirable changes in acidity. Sodium acetate also contributes a slightly salty and vinegary flavor to foods. It is also used in textile dyeing, as a concrete sealant, and in heating pads and hand warmers.

Side Effects

Sodium acetate is generally recognized as safe (GRAS) by regulatory bodies like the FDA when used in accordance with good manufacturing practices. The European Food Safety Authority (EFSA) has also evaluated sodium acetate and considers it safe at the levels typically used in food. No Acceptable Daily Intake (ADI) has been established, indicating a low level of concern for toxicity. However, excessive consumption of sodium from any source, including sodium acetate, may contribute to elevated blood pressure in susceptible individuals. Individuals with sodium-restricted diets should be mindful of their overall sodium intake. Allergic reactions are rare, but possible in sensitive individuals.

Regulatory Status

Sodium acetate (E262i) is approved for use as a food additive in the European Union (EU) and the United States. It is listed in the EU's permitted food additives list and is subject to purity criteria. In the United States, it is regulated under the Code of Federal Regulations (CFR) as a GRAS substance. Its use is typically limited to the minimum amount necessary to achieve its intended technical effect.
