Summary Trichloroethylene cottonseed oil miscellas from prime meats heated during desolventization above 180°F. produced a refined oil darker than prime. When the miscellas were heated above 190°F., the bleached oils produced from them were darker than prime. Extracting prime meats with trichloroethylene above 118°F. produced an oil darker than prime. There is some evidence that heating the meats above about 170°F. also gives a dark oil. Dilute miscellas, when desolventized, produced a darker oil than more concentrated ones probably because of the longer time required for solvent removal. It is believed that the darkening is primarily a function of time and temperature, rather than the solvent used.
