Supercritical CO Extraction of Rice Bran Oil -the Technology, Manufacture, and Applications.

Rice bran is a good source of nutrients that have large amounts of phytochemicals and antioxidants. Conventional rice bran oil production requires many processes that may deteriorate and degrade these valuable substances. Supercritical CO extraction is a green alternative method for producing rice bran oil. This work reviews production of rice bran oil by supercritical carbon dioxide (SC-CO) extraction. In addition, the usefulness and advantages of SC-CO extracted rice bran oil for edible oil and health purpose is also described.
