Abstract: A process for refining and degumming edible oils by ultrafiltration which produces a permeate fraction with reduced phosphatide content and retentate with increased phosphatide content, and wherein the ultrafiltration membrane is composed of a polymerical polymer of a vinylidene difluoride monomer.

Abstract: A solvent extraction free, caustic refining free, process for producing refined soybean oil from soybeans is described in which soybeans, after cleaning, cracking and dehulling, are crushed in less than 60 seconds while heating the soybeans to a frictionally generated temperature of from about 300° F. to about 370° F. Free fatty acids are then removed through physical refining, instead of previously employed caustic refining, since the low level of nonhydratable phospholipids does not create undesirable flavors during the physical refining process. The resultant oil exhibits a significantly greater frylife that non-hydrogenated soybean oil produced by solvent extraction and caustic refining.

Abstract: A solvent extraction free, caustic refining free, process for producing refined soybean oil from soybeans is described in which soybeans, after cleaning, cracking and dehulling, are extruded through a screw extruder in less than 30 seconds while heating the soybeans to a frictionally generated temperature of from about 300° F. to about 370° F. These conditions produce soybean oil that is low in nonhydratable phospholipids. As a result, free fatty acids can be removed through physical refining, instead of previously employed caustic refining, since the low level of nonhydratable phospholipids does not create undesirable flavors during the physical refining process. The process also includes conventional degumming and bleaching of the soybean oil after extraction and before physical refining.
