What it is

Ethoxyquin is a synthetic antioxidant. It is produced by reacting p-phenetidine with acetone. It is used to prevent spoilage and maintain the quality of certain foods.

Why it's used

Ethoxyquin is added to foods to prevent oxidation, which can cause rancidity and loss of flavor. It is most commonly found in seasoning mixes, marinades, sauces, and some frozen meals.

Health notes

In the United States, ethoxyquin is approved as a food additive. The FDA has established regulations for its use. International bodies like JECFA have evaluated ethoxyquin, and it is permitted in some countries. Some studies have raised questions about its safety, particularly regarding potential metabolites, but regulatory agencies continue to permit its use within specified limits.

Allergen info

Ethoxyquin is not derived from any of the nine major allergens recognized by the FDA. It does not contain gluten.
