The present invention relates to a method and solvent for use in extracting oil from oil bearing materials, preferably a triglyceride rich oil is selectively extracted from the oil bearing material. More preferably, the present invention relates to a solvent, comprised of a hydrocarbon and a fluorocarbon, and a method that will preferably remove an amount of oil comprised of greater than 95% by weight triglycerides and other non-polar constituents from an oil bearing material, such as a soybean material. The present invention relates to a solvent for use in extracting oil from an oil bearing material, such as soybeans, with the solvent resulting in the selective extraction of a triglyceride rich oil, which contains 95% or greater triglycerides and non-polar constituents, with the solvent comprised of a hydrocarbon, preferably hexane, and a fluorocarbon, so that the solvent has a viscosity less than 2.6 centipoise and a polarity of less than 0.1. The present invention also relates to a method of using the solvent to extract the triglyceride rich oil, with the method including preferably extracting the oil at a temperature ranging between 35° C. and 55° C., and then preferably cooling resulting miscella to a temperature ranging between 15° C. and 25° C.
