Process for the preparation of rice bran oil low in phosphorous content

摘要

The present invention relates to a simple, and economical process for the preparation of rice bran oil low in phosphorous content (<10 ppm) by treatment of crude rice bran oil to substantially remove the phosphoglycolipids responsible for the residual phosphorus in degummed rice bran oil, said process comprising:a) treating the crude rice bran oil at ambient temperature with 5% of boiling water and separating the sludge formed to obtain a clarified oil,b) treating the clarified oil thus obtained with 0.5% to 10% of a reagent selected from the group consisting of mono-, di- or triethanolamine to obtain said low phosphorous content oil.
