1. A method for reducing neutral oil losses during a neutralization step comprising the following steps:
- (1) mixing an acid-treated vegetable oil with a base to neutralize (a) free fatty acid and (b) added acid in the acid-treated vegetable oil to obtain a pretreated mixture;
(2) subjecting the pretreated mixture to at least two cycles of localized shear effects, said cycles being arranged in succession, each cycle comprising a step of forcing the pretreated mixture at a pressure through one or more nozzles, each cycle of localized shear effects having a shear duration time of less than 5×

Abstract
A method for reducing neutral oil losses during a neutralization step including (1) mixing an acid-treated vegetable oil with a base to neutralize (a) free fatty acid and (b) added acid in the acid-treated vegetable oil to obtain a pretreated mixture; (2) subjecting the pretreated mixture to at least two successive cycles of localized shear effects, each cycle including a step of forcing the pretreated mixture at a pressure through one or more nozzles, each cycle of localized shear effects having a shear duration time of less than 5×10−5 seconds and a shear rate of at least about 6000 sec−1.
