PROBLEM TO BE SOLVED: To prepare a completely disinfected cooked and packed rice by exterminating thermoresistant microorganisms as well as general microorganisms. SOLUTION: A definite amount of washed and water-soaked rice is filled in a tray for one meal and heated in a closed chamber with a pressurized hot saturated steam to effect the sterilization treatment and the gelatinization of the rice. The gelatinized rice is added with cooking water, cooked and sealed in the tray with a covering material. The sterilization treatment is preferably carried out by intermittently flushing the pressurized hot saturated steam to the rice filled in the tray for one meal, e.g. flushing the pressurized hot steam for 5-10sec and repeating the cycle 6-8 times. |
