Abstract
The presence of phosphoglycolipids (PGL) in degummed rice bran oil (RBO) affects the color in the
subsequent refining process, posing problems in producing a final product of acceptable quality. A nonporous
membrane could achieve near complete removal of phospholipids even under hexane-diluted
conditions, including PGL present in RBO. PGL from glycolipid fractions isolated from various membrane
process stream samples, analyzed by 1H, 13C and 31P NMR spectroscopic techniques, indicated the
absence of PGL in the permeate, besides identifying them to be oleates/linoleates of phosphatidic acid.
Hence, the efficacy of a nonporous membrane in the removal of PGL suggests its application for effective
degumming of crude RBO.
