Ethoxyquin : An Antioxidant Used in Animal Feed

الملخص EN

Ethoxyquin (EQ, 6-ethoxy-1,2-dihydro-2,2,4-trimethylquinoline) is widely used in animal feed in order to protect it against lipid peroxidation.

EQ cannot be used in any food for human consumption (except spices, e.g., chili), but it can pass from feed to farmed fish, poultry, and eggs, so human beings can be exposed to this antioxidant.

The manufacturer Monsanto Company (USA) performed a series of tests on ethoxyquin which showed its safety.

Nevertheless, some harmful effects in animals and people occupationally exposed to it were observed in 1980’s which resulted in the new studies undertaken to reevaluate its toxicity.

Here, we present the characteristics of the compound and results of the research, concerning, for example, products of its metabolism and oxidation or searching for new antioxidants on the EQ backbone.
