Applications of 91-53-2
Ethoxyquin has diverse applications:
- Food Preservation: Used extensively in animal feeds to prevent rancidity and maintain nutritional quality by protecting fats and fat-soluble vitamins from oxidative damage.
- Agricultural Use: Initially registered as a pesticide for controlling scald on pears during post-harvest processing.
- Spice Preservation: Employed in some spices to prevent color loss due to oxidation of natural carotenoid pigments.
Despite its benefits, regulatory scrutiny has limited its use in certain regions due to health concerns.
