ABSTRACT:
Method for sterilizing foods using both ultra-high pressures and high temperatures. The instantaneous temperature change that occurs when pressure is applied combines a high-temperature short-time process with ultra-high pressure to deliver a fast and therefore gentle thermal process to a pre-packaged product. The process involves heating a food to a pre-pressurized temperature, subjecting the food to ultra-high pressure, which instantaneously raises the temperature of the food, and then releasing the pressure so that the temperature returns to the original pre-pressurized temperature. The method leverages the adiabatic temperature rise which occurs when the food is hydrostatically pressurized, coupled with the lethality of the pressure, to achieve appropriate sterilization conditions.
