E386 - Dinatrium-EDTA

Origin

Disodium EDTA (Ethylenediaminetetraacetic acid disodium salt) is a synthetic amino acid derivative. It is produced chemically from ethylenediamine, formaldehyde, and sodium cyanide. It is a chelating agent, meaning it can bind to metal ions.

Usage

Disodium EDTA is primarily used in the food industry as a preservative, sequestrant, and stabilizer. It prevents discoloration, rancidity, and the formation of precipitates in various food products. It binds to metal ions like iron and copper, which can catalyze oxidation reactions that degrade food quality. It is found in canned goods, sauces, dressings, and processed vegetables. It is also used in the pharmaceutical and cosmetic industries for similar purposes, such as stabilizing formulations and enhancing the effectiveness of preservatives. In medicine, it is used in chelation therapy to remove heavy metals from the body.

Side Effects

Disodium EDTA is generally considered safe for food use within permitted levels. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has established an Acceptable Daily Intake (ADI) of 0-2.5 mg/kg body weight. High doses of EDTA can cause gastrointestinal disturbances, such as nausea, vomiting, and diarrhea. Excessive intake may also interfere with the absorption of essential minerals like zinc, calcium, and iron. However, these effects are typically observed at levels far exceeding those found in food. Some studies have raised concerns about potential developmental or reproductive toxicity at very high doses, but these findings are not conclusive at levels relevant to food consumption.

Regulatory Status

Disodium EDTA is approved for use as a food additive in many countries, including the United States, the European Union, and Canada. Regulatory bodies like the FDA and EFSA have evaluated its safety and established maximum permitted levels in various food categories. In the EU, it is designated as E386. The FDA includes it in its list of substances generally recognized as safe (GRAS) when used in accordance with good manufacturing practices.
