秋橄榄番茄红素超临界CO2萃取工艺研究

摘要

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 CO 2 flow rate, the optimal pa-rameter to extract the lycopene from the fruits of autumn olive was using 30 MPa extraction pressure, extracting for 1.5 h at 45℃.%以野生秋橄榄为原料，采用三因素三水平正交试验设计对果实番茄红素无助提剂条件下的超临界CO2提取（SFE）工艺进行了研究。结果表明，在检测的3个因素中萃取压力对秋橄榄果实番茄红素的提取效率影响最大，其次为温度和提取时间。在CO2流速约为60 L/h的条件下，果实番茄红素提取的最佳工艺参数为45℃，30 MPa，每次1.5 h。
