Abstract

Provided herein are a microwave retort system and a process for heating food products using a microwave retort system, such as to pasteurization and/or sterilization temperatures. Food product formulated for treatment in microwave retort processes are also provided. In one aspect, the microwave retort system includes a microwave zone having one or more microwave temperature sections in which a liquid medium is maintained at a temperature below sterilization temperatures during the microwaving process. The processes and systems described herein heat the products to pasteurization or sterilization temperatures while preventing the products, including outer surfaces, reaching a temperature greater than 135 F. The microwave retort processes and systems advantageously provide products with the taste and organoleptic properties equivalent to or nearly equivalent to an otherwise identical freshly prepared product and significantly better than otherwise identical food products that have undergone a conventional immersion or saturated steam retort process.
