چکیده انگلیسی
A green approach of using supercritical CO2 in a silica-packed column via adsorption and desorption steps has been developed to enrich β-carotene in the 10% β-carotene concentrate made from crude palm oil. In the adsorption stage, the yield of the β-carotene poor fraction with the content of 3% was 82.2% when the pressure, temperature, CO2 flow rate and the time were 25â¯MPa, 60â¯â, 3â¯kg/h, and 180â¯min, respectively. The rich β-carotene fraction adsorbed in the column was thoroughly extracted out by supercritical CO2 when the pressure, temperature, flow rate and time were 35â¯MPa, 70â¯â, 3â¯kg/h, and 120â¯min, respectively, in which the β-carotene content reached 27% and the yield reached 22.3%. This two-step process is an efficient way to prepare natural β-carotene with high content and has potential applications in the concentration of value-added components.
