Abstract
This invention relates to improved methods for treating organic acid-treated phosphatides. More particularly, this invention relates to improved methods comprising providing a phosphatide-containing material obtained from organic acid refining of vegetable oil, adjusting the pH of the phosphatide-containing material to form a neutralized phosphatide, and drying the neutralized phosphatide for a time sufficient to produce a dried phosphatide containing hydrolyzed lecithin.
Claims10
A process for treating a phosphatide-containing material, comprising:
- (a) providing a 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) adjusting the pH of the phosphatide-containing material to a value of from about 5 to about 7 to form a neutralized phosphatide mixture;
- and
- (c) drying the neutralized phosphatide mixture for a time sufficient to convert the neutralized phosphatide mixture into a vapor phase and a dried phosphatide containing hydrolyzed lecithin.
