E323 - Anoxomer

Origin

Anoxomer is a synthetic antioxidant polymer. It is created through the polymerization of divinylbenzene and styrene, followed by alkylation with t-butyl alcohol and ethyl alcohol. This process results in a high molecular weight compound designed to be poorly absorbed by the body.

Usage

Anoxomer is used as an antioxidant in various food applications to prevent or delay the oxidation of fats and oils, thereby extending the shelf life of food products. It is particularly effective in preventing rancidity. Its high molecular weight limits its absorption in the digestive tract, which is a key factor in its safety profile. It is approved for use in specific food categories under certain regulatory conditions. The typical usage levels are determined based on the specific food product and regulatory guidelines.

Side Effects

Due to its high molecular weight, Anoxomer is poorly absorbed from the gastrointestinal tract, minimizing systemic exposure. Studies have indicated that it is generally well-tolerated. However, as with any food additive, there is a potential for allergic reactions in sensitive individuals, although such reactions are rare. Regulatory bodies like the EFSA and FDA have evaluated its safety based on available toxicological data. No ADI (Acceptable Daily Intake) has been explicitly established, reflecting its limited absorption and perceived low toxicity. Further research may be conducted to continuously assess its safety profile.

Regulatory Status

Anoxomer is approved for use as a food additive in several countries, including the United States, where it is regulated by the FDA. Its use is subject to specific regulations regarding the types of food in which it can be used and the maximum permitted levels. The European Union does not currently permit the use of Anoxomer as a food additive. The regulatory status can vary significantly between different regions, so it's important to consult local regulations for specific applications.
