Novel method for refining soybean oil

Abstract

Summary A process for making break‐free soybean oil is described in which crude oil is treated with a small amount of an organic acid anhydride and then degummed by water addition and phase separation. The break‐free oil can be used for industrial applications or processed to an edible grade of oil without alkali‐refining. Laboratory data are presented, comparing quality of edible oils, processing losses, and composition of deodorizer distillates of alkali‐refined soybean oils with oils prepared by the degumming process described in this paper.
