Novel method for refining soybean oil

  • Lester P. Hayes
  • Hans Wolff


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.
