This study was conducted to compare the effectiveness of pressure-assisted thermal processing (PATP) in preserving the texture, color, and carotene content of carrot cylinders in the pressure range of 500 to 700MPa and the temperature range of 95 to 121 ◦C. The effectiveness of PATP was compared with that of conventional thermal processing(TP)bymatchingcarrotpreprocesstemperaturehistory.Results indicated thatundercomparableprocess temperatures (up to 105 ◦C), PATP retained the carrot quality attributes such as color and carotene content better than TP. However, process and preprocess thermal history at 121 ◦C greatly influenced carrot textural change and pressure protective effects were less pronounced. This study demonstrated that PATP has the potential to produce low-acid foods with a relatively better quality than TP.
