Various embodiments of processing systems and components for sterilization or pasteurization and associated methods of operation are described herein. For example, a method of sterilization or pasteurization includes immersing an item in an immersion fluid, and the immersed item is subject to a hydrostatic pressure of the immersion fluid. The method also includes applying microwave energy to the item while the item is immersed in the immersion fluid and subject to the hydrostatic pressure of the immersion fluid. The hydrostatic pressure of the immersion fluid prevents the water content of the item from causing steam explosion in the item while the microwave energy is applied. The method further includes heating the item immersed in the immersion fluid to a target temperature with the applied microwave energy, the target temperature being sufficient to achieve sterilization or pasteurization of the item.
