the HAA increased as time progressed and did not noticeably differ among treatment conditions. However, after ripening, it is likely that the hyperbaric pressure at 0.9 MPa caused a significantly higher HAA compared to 0.1 MPa at 13◦C. Overall, hyperbaric treatment at 20◦Chas potential to extend tomato shelf-life during short treatment durations without adverse impact on quality during ripening. Morestudy is required to determine optimal pressures and treatment times to produce the highest quality.
