Abstract
The present invention relates to a process for the isolation of a glycolipid enriched fraction from rice bran oil by subjecting crude rice bran oil to at least two steps of dewaxing/degumming, treating sludge obtained as a byproduct of the second said dewaxing/degumming to hexane extraction, and separating the glycolipid fraction. The glyolipid fraction so obtained can be further purified.
Claims8
A process for the isolation of a glycolipid enriched fraction from rice bran oil, said process comprising (i) subjecting crude rice bran oil to dewaxing/degumming at least two times with formation of a sludge as a by product and, (ii) treating the sludge obtained as a byproduct to hexane extraction, and separating the glycolipid enriched fraction thereby obtaining the glycolipid enriched fraction.
A process for the isolation of a glycolipid fraction from rice bran oil, said process comprising degumming/dewaxing crude rice bran oil by adding boiling water thereto with stirring to form an emulsion, separating the emulsion thus obtained into a supernatant fraction and sludge, subjecting the supernatant fraction to further degumming/dewaxing by adding water at elevated temperature with stirring, separating the resultant emulsion into a supernatant fraction containing substantially pure oil and a sludge, extracting at least once the sludge so obtained with hexane followed by separating the glycolipid fraction.
