Supercritical CO2 extraction of β-carotene from sweetpotato storage roots

摘要：

This work describes the influence of pretreatment conditions and some operative parameters of supercritical carbon dioxide (SC-CO2) extraction employed for the isolation of β-carotene from the sweetpotatoes (Ipomoea batatas(L.)Lam.).As the results showed,the pretreatment conditions were of moisture content at 4％ and particle size at 0.280mm,a maximum of 3.45 mg/g of β-carotene was extracted by SC-CO2 in 4 h at 50℃ and 25 MPa,with CO2 flow rate at 15 L/h；the extraction amount of β-carotene could increase by 0.66 mg/g with the addition of 5％ acetone as a co-solvent.
