Abstract:
A process for recovering fatty acids from an organic-acid treated phosphatide, comprising:(a) providing an phosphatide-containing material selected from the group consisting of a phosphatide-enriched aqueous phase obtained from an organic acid refining process, an organic acid-treated phosphatide phase obtained from an organic acid refining process, or a mixture thereof; (b) maintaining the phosphatide-containing material at acidic pH for a time sufficient to produce a reaction mixture containing free fatty acids; (c) distilling the reaction mixture for a time sufficient to convert the reaction mixture into a vapor phase and a liquid residue; and (d) condensing the vapor phase to form a distillate containing at least about 97 percent by weight free fatty acids.
