Thus, in order to obtain the required lethality at shorter
processing times, the possible synergistic effect of SC-CO2 + HPU
technique was investigated. The process conditions tested were the
same as before: 12 MPa, 40 ◦C, but shorter treatment times (5, 10,
15, 20 min) and 10W ultrasound power was concurrently applied
(Fig. 3).
