The invention relates to a box-type packaged fresh corn normal-temperature fresh-keeping method, which comprises the following steps: peeling, cleaning and sterilizing the corns by a peeling machine; performing enzyme inactivation treatment by microwave synergistic color fixative, air-drying, coating, performing antibacterial, antioxidant and anti-aging coating treatment by surfactant, packaging the air-dried corn in a high-temperature and high-pressure resistant polypropylene packaging box, and sterilizing under back pressure. According to the invention, the sterilization process of gradient temperature rise and pressure rise, constant-temperature and constant-pressure sterilization and gradient temperature reduction and pressure reduction of the sterilization pot by using the synergistic circulation of nanometer water ions and ozone micro-nano bubbles is adopted, the bag explosion rate is reduced, nanometer atomized water can excite water molecules to form hydroxyl negative ions and hydrogen positive ions with very strong binding capacity, the specific surface area is greatly enhanced due to the nanometer small-size effect, and the sterilization and bacteriostasis performance is more excellent. Can increase the penetration capability of sterilization media such as hot water, steam and the like in the sterilization pot and improve the sterilization effect. |
