Abstract
The invention is drawn to a process for isolating and purifying a phytosterol composition from a pulping soap by first extracting a creamy precipitate from the pulping soap using a solvent mixture of water, ketone, and hydrocarbon, and then purifying the cremy precipitate to form the phytosterol composition. The invention also includes the phytosterol composition formed by this method.
