Microwave-assisted thermal sterilization (MATS) has the potential to produce food with a higher quality and longer shelf-life. Fast volumetric heating created by microwave reduces the time for the product to reach desired processing temperature and the overall processing time (Guan et al., 2003). Process validation has been conducted using a 10-kW 915-MHz microwave sterilization system and single-mode cavity for 7-oz to 13-oz food trays or 8-oz pouches (Tang et al., 2006). Subsequently, the MATS has been accepted by the Food and Drug Administration (FDA) for pre-packaged commercial sterilization of homogeneous and non-homogeneous foods (Tang, 2015). MATS has also received a non-objection notification from the Food Safety and Inspection Service (FSIS) of the USDA for production of shelf stable foods (Tang, 2015).
