Supercritical fluid extraction, fractionation, and characterization of wheat germ oil

Scope and method of study. The purpose of this study was to examine the ability of supercritical fluid technology to extract and fractionate wheat germ oil.; Findings and conclusions. Supercritical carbon dioxide extraction yield was similar to that of conventional hexane extraction product. Supercritical fluid fractionation technique was effective in removing undesirable free fatty acids from crude wheat germ oil while retaining bioactive components.
