simultaneous rice bran oil stabilization and extraction

  • Extraction and Purification of Gamma-Tocotrienol from

    Until recently, rice bran was considered a by-product of rice milling and was primarily used as a supplemental source of protein and vitamins B and E in animal feeds. The development of heat stabilization techniques has allowed rice bran to be available in other forms such as rice bran oil (Rice Knowledge Bank 2009).

  • Extraction and refining of edible oil from extrusion

    Rice bran oil extracted from extrusion‐stabilized bran was processed to a high quality salad oil. Stabilization prevented free fatty acid formation in rice bran prior to solvent extraction of the oil and thus increased the yield of refined oil. The flake form of the stabilized bran allowed rapid solvent percolation and efficient lipid extraction.

    Rice bran is an underused coproduct of rice milling. The value is partially captured through extraction and refining of the rice bran oil. The capital costs have limited the ability of the U.S. rice milling industry to capture this value. However, rice bran oil has performance properties competitive to other widely used oils.
