applied different HPTP on tomato and found that the ratio of inactivation of the enzymes tested, like polygalacturonase and pectinmethyl esterase, was reduced at pressures between 300 and 600 MPa at 70◦C of temperature at the end of the pressure build-up phase. In our study, the applied conditions were similar, although the results were dif-ferent because the rate of inactivation of PPO increased with increasing pressure intensities. However, the effect of high pressure treatment on the inactivation of enzymes is highly dependent of the food matrix and thatcould explain the differences in the response of each product to the treatments applied.
