Abstract:
1. A method of fractionating corn germ extraction material, comprising the steps of: a) establishing an amount of corn germ extraction material in an amount of supercritical carbon dioxide; b) delivering said amount of corn germ extraction material in said amount of supercritical carbon dioxide to a first corn germ extraction material separation zone; c) maintaining said amount of corn germ extraction material in said amount of supercritical carbon dioxide in said first corn germ extraction material separation zone at a temperature of between about 60° C. and about 110° C.; d) adjusting pressure of said amount of corn germ extraction material in said amount of supercritical carbon dioxide in said first corn germ extraction material separation zone to between about 200 bar and about 400 bar to achieve a density of said supercritical fluid of between about 0.75 g/mL and about 0.85 g/mL; e) separating a phosphatide fraction from said corn germ extraction material in said amount of supercritical carbon dioxide resulting in a triglyceride fraction and a fatty acid fraction remaining in said amount of supercritical carbon dioxide.
