Three pressure transmitting fluids (water, ethylene glycol, and ethanol) and three liquid foods (orange juice, whole, and skim milk) were pressurized at 100-400 MPa and at 5, 20 and 35 degrees C, using different compression rates (100, 200, and 300 MPa/min) to evaluate the adiabatic heating phenomena during high hydrostatic pressure (HHP) processing. A pressure vessel (3 L volume) in which liquid foods could be introduced directly was used to demonstrate the compression heating phenomena in large-scale commercial conditions.
