A process for the production of micronutrients rich rice bran oil using supercritical carbon dioxide extraction and the said process comprising: a. packing of parboiled or rice bran with glass beads in a container cage inside the extraction vessel in a ratio ranging 1:0 to 1:2 (w/w); b. pressurizing the vessel to the required pressure ranging 200-600 bar at a temperature ranging 30-80oC and soaking raw rice bran for a period ranging 10-30 mints; c. subjecting to dynamic extraction over a period ranging 0.5-4 hrs with CO2 flow rate ranging 20-50g/min; d. passing the oil laden gas from the extractor through a heated metering valve and depressurizing the extracted rice bran as obtained in step c) at a specified rate and storing CO2 in the recycle tank and collecting the extracted oil from the receiver.
