| Abstract: | Sub-critical carbon dioxide extraction enhanced by ultrasound was applied to extract lutein from chlorella.The effects of extraction parameters including temperature, pressure, flow rate of CO_2,co-solvent amount, time and ultrasonic power on the yield of lutein were investigated with single factor experiments.The maximal yield of lutein was obtained for extraction temperature of 25℃, pressure of 11MPa, CO_2 flow rate of 30kg/h, co-solvent amount of 1.5mL ethanol/g chlorella, time of 3 hours with ultrasonic power of 750W. Furthermore, the preliminary exploration of ultrasonic enhancement mechanisms in sub-critical carbon dioxide was conducted. |
