Abstract

The extraction and determination of ethoxyquin is becoming increasingly important as products, which are labeled as "natural" are becoming more common. This manuscript investigates the use of supercritical fluids in the extraction of ethoxyquin from lean beef and beef fat. Three fluids were examined: carbon dioxide, trifluoromethane, and 1,1,1,2-tetrafluoroethane. Carbon dioxide appeared to react with ethoxyquin during the extraction. Methanol modified hydrofluorocarbons provided more complete extractions over pure hydrofluorocarbon fluids. Methanol modified 1,1,1,2-tetrafluoroethane was usedin the extraction of ethoxyquin from lean beef and beef fat, and provided a quantitative extraction at the 0.5 ppm level.
