UHPH processing was carried out in a bench-scale high-pres-sure homogenizer (JC-10C series by Guangzhou Juneng biology &
technology Co., Ltd., Guangdong, China). The homogenizer consists
of an oil booster pump connected to a high pressure intensifier for
continuous pressurization of the process fluids up to 207 MPa. The
maximum flow rate of juice that can be achieved in the homoge-nizer is 10 L/h. Upon pressurization, the fluid is fed into a high-pressure disruption valve. The flow through the micrometric gap
causes the physical disruption of the microbial species.
