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
