ABSTRACT:
The present invention relates to the use of “green” or relatively benign solvents such as ethanol, ethanol/water, isopropyl alcohol, isopropyl alcohol/water, ethyl lactate, acetone, butanol, isoamyl alcohol, or ethyl acetate to extract phytosterols from wet corn fiber. The resulting oil product contains free phytosterols and free fatty acids.
