E NumberE324
Chemical FormulaC14H19NO

Purpose and Function

Ethoxyquin (E324) is used in the food industry as an antioxidant. It helps prevent the oxidation of fats and oils, thereby extending the shelf life of various food products, particularly those with high fat content. Its applications include:

  • Animal feed: Widely used as an antioxidant in animal feeds, especially fish meal, to prevent spoilage and rancidity.
  • Spice stabilization: Sometimes used to preserve the color of spices such as paprika and chili powder.
  • Industrial applications: In addition to food uses, ethoxyquin is used as an antioxidant in rubber production and other non-food applications.

Ethoxyquin is more commonly found in animal feed than in food products intended for human consumption.


Potential Risks and Side Effects

Ethoxyquin (E324) has raised safety concerns, and its use is subject to regulatory scrutiny:

  • Health concerns: Some studies suggest potential risks associated with ethoxyquin, including liver and kidney issues, allergic reactions, and other adverse health effects when consumed in high amounts.
  • Regulatory status: The use of Ethoxyquin (E324) in human food is restricted or banned in many regions, including the European Union, due to safety concerns. Its use in animal feed is also subject to strict limits.
  • Human exposure: While direct use in food products for human consumption is limited, indirect exposure through animal products (meat, fish) fed with ethoxyquin-treated feed may occur.

Due to these safety concerns, the use of ethoxyquin as a food additive is tightly regulated and often prohibited.
