摘要:

以番茄为原料,通过单因素试验及正交试验,研究酶辅助超临界CO2流体萃取番茄红素的工艺条件。结果表明,果胶酶和纤维素酶破壁处理的最佳反应条件为温度40℃、pH4.0、加酶量为4%果胶酶和3%纤维素酶、反应时间1.5h;超临界CO2流体萃取番茄红素的最佳工艺条件为萃取压力15Mpa、萃取温度40℃、萃取时间4h。

Abstract:

Single factor method and orthogonal array design were adopted to explore the optimal enzyme-assisted supercritical CO2 extraction process of lycopene from tomato. Results revealed that the optimal processing conditions for degrading cell wall with pectinase and cellulose were 4% of pectinase amount and 3% of cellulase amount, 1.5 h of reaction at 40 ℃ and pH 4.0, and the optimal processing conditions for supercritical CO2 extraction were 15 MPa of extraction pressure and 4 h of extraction at 40 ℃.

Key words: lycopene, cell wall degradation, supercritical CO2 extraction
