Abstract:

Effect of combinatorial treatment between ultra-high hydrostatic pressure and moderate temperature on the contents of lycopene and vitamin C in tomato juice was investigated. Results indicated that the treatment with temperature of 33.5 ℃, pressure of 469.2 MPa and pressure-holding time of 14.0 min could result in the increase of lycopene content when compared with the control, while the isomers of lycopene remained unchanged; in contrast, vitamin C content did not exhibit an obvious change.

Key words: ultra-high hydrostatic pressure, moderate temperature, tomato juice, lycopene, isomers, vitamin C
