What is ethoxyquin?

Ethoxyquin is a synthetic antioxidant primarily used as a food preservative. Its chemical name is 6-ethoxy-1,2-dihydro-2,2,4-trimethylquinoline. Ethoxyquin was initially developed as a stabilizer for rubber, but its application expanded to the food industry due to its antioxidative properties.

In the food industry, ethoxyquin is commonly used as a preservative in animal feeds, pet foods, and certain food products. It helps prevent the oxidation of fats and oils, extending the shelf life of these products by inhibiting the development of rancidity and off-flavors caused by lipid oxidation.

Ethoxyquin has also found application in the agriculture sector as a pesticide and plant growth regulator. However, its use as a pesticide is regulated in many countries, and maximum residue limits may be in place.

ethoxyquin in spices

Ethoxyquin is sometimes used as a preservative in spices to prevent oxidation and extend their shelf life. It helps maintain the quality and flavor of spices by inhibiting the degradation of essential oils and other volatile compounds that contribute to their aroma and taste.

ethoxyquin in dog food

Ethoxyquin remains stable at the high temperatures required to process dog foods during extrusion. It is important in protecting fats and oils from degrading, losing available calories, and becoming rancid.
