概要
- 論文の詳細を見る
Extraction of oil from rice bran with supercritical carbon dioxide (SC-CO2) at pressures of 150 to 350 kg/cm2 G at 40°C was demonstrated. The constituents of the selective fractions obtained at different pressures differed. Fractions obtained at higher pressures contained less free fatty acid and waxes or unsaponifiables. The phosphorus and iron contents were very low in the SC-CO2 extracted oil, while the color of the oil was significantly lighter than that of hexane-extracted oil. The yield of low acid value oil was comparable to that for hexane extraction. One problem of the SC-CO2 oil is its poor oxidation stability. This method of extraction may be effective in simplifying the processing of edible rice bran oil. Grinding the raw material was found to be effective in decreasing the CO2 required and shortening the extraction period.
