Abstract:In this paper，orthogonal test design of three factors at three different levels was applied to optimize the lycopene extraction technology from autumn olive using supercritical fluid extraction（SFE）.The results showed that the extraction temperature had significant influences on extraction yield of lycopene.The effects of extraction temperature and extract time were in order reduced.Under the 60 L/h CO2flow rate，the optimal parameter to extract the lycopene from the fruits of autumn olive was using 30 MPa extraction pressure，extracting for 1.5 h at 45℃.
