E323 — Anoxomer

E323, known as Anoxomer, is a synthetic, non-digestible polymeric antioxidant designed to prevent the oxidation of fats and oils in food products, thereby extending their shelf life. It was developed to introduce established antioxidants in a non-absorbable form, minimizing potential health risks associated with their digestion. 

Danger Level: 2 (Limited Approval) – Anoxomer is not approved for use as a food additive in the European Union. 

Purpose in Products

Anoxomer functions primarily as an antioxidant in food products:

  • Antioxidant: Prevents the oxidation of fats and oils, maintaining product freshness and preventing rancidity.

Common applications include:

  • Fried Foods: Such as potato chips and fried snacks.
  • Edible Oils: Including cooking oils and shortenings.

Health Considerations

Anoxomer was designed to be non-digestible, reducing potential health risks associated with the absorption of traditional antioxidants. However, due to limited approval and lack of comprehensive studies, its safety profile is not well-established.

Impact on Children

There are no specific studies regarding the consumption of Anoxomer by children. Given its limited approval status, it is advisable to avoid products containing this additive.

Impact on Taste

Anoxomer is generally used in concentrations that do not affect the taste, odor, or color of food products.

Compatibility with Other Additives

Anoxomer can be combined with other food additives, but specific interactions are not well-documented due to its limited use.

Natural Occurrence

Anoxomer does not occur naturally and is synthesized through condensation polymerization of divinylbenzene with a mixture of antioxidant monomers, including tert-butylhydroquinone, tert-butylphenol, hydroxyanisole, p-cresol, and 4,4′-isopropylidenediphenol. 

Alternatives and Substitutes

Depending on the application, alternatives to Anoxomer may include:

  • Natural Antioxidants: Such as tocopherols (Vitamin E) and ascorbic acid (Vitamin C).
  • Other Synthetic Antioxidants: Like butylated hydroxyanisole (BHA, E320) and butylated hydroxytoluene (BHT, E321).

Regulation

Anoxomer (E323) is not approved for use as a food additive in the European Union. Its approval status in other regions varies, and it is essential to consult local regulations for guidance. 

Conclusion

E323 (Anoxomer) is a synthetic, non-digestible polymeric antioxidant developed to prevent oxidation in food products. Due to its limited approval status and lack of comprehensive safety data, its use in food products is restricted in many regions, including the European Union.
