PURPOSE:To thermally sterilize a complex food with microwaves without using a retainer and destroying the food by packaging the complex food with a heat-shrinkable film, primarily heating the packaged food and then heating the resultant food with microwaves. CONSTITUTION:A complex food such as croquette, 'GYOZA' (fried dumpling stuffed with minced pork) or 'DAIFUKU' (rice cake stuffed with bean jam) having the skin and contents is contained in a tray-like container and packaged with a heat shrinkable film having a gas discharging means formed by providing slits, etc., or sealing the film partially leaving an unsealed part, etc. The packaged food is then primarily dried with hot air or an oven, irradiated with infrared rays, etc., to shrink the heat shrinkable film. Sterilization of the package is further carried out by heating with microwaves. |
