Why Is Ethoxyquin a Good Preservative for 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.
Why Do Some People Question the Use of Ethoxyquin in Dog Food?
Despite the fact that all studies conducted to date prove that ethoxyquin is safe for use in all animal foods when used at approved levels, rumors continue to circulate to the contrary.
Individuals who seek to discredit the use of ethoxyquin will often cite certain studies that showed toxic effects in animals fed ethoxyquin. What these individuals fail to point out is that the animals in these studies were given excessive amounts of ethoxyquin—20 to more than 50 times the maximum limit—before negative effects were exhibited.
