Ethoxyquin

Ethoxyquin is a quinoline derivative used as an antioxidant to control the browning of certain fruits and vegetables, and to prevent the rancidity of animal fats in pet foods. It is also used as a pesticide to control scald on pears and other fruits.

Ethoxyquin has a chemical formula of C14H19NO. It is a derivative of quinoline, with an ethoxy group (-OCH2CH3) attached to the 6-position and a tertiary butyl group attached to the 2-position.

Uses

Ethoxyquin is primarily used as a food preservative and a pesticide. It is approved by the FDA for use in animal feeds to inhibit lipid peroxidation, which can lead to rancidity. It is also used as a pesticide to control scald on pears and other fruits.

Safety

The safety of ethoxyquin has been a subject of controversy. Some studies have suggested that it may have potential health risks, including carcinogenicity. However, the EFSA and the FDA have concluded that it is safe for use in food and animal feed at current levels of intake.

Regulation
