A food containing device containing food is included and provided with a device for preventing continuous oxygen increasing in the food containing device. A discharging port capable of preventing air inflow or a transition part facilitating material taking is additionally arranged on a transformable food containing device body, and an oxygen inflow preventing device, other oxygen inflow preventing components and the like are formed, the situation that food in the food containing device is constantly oxidized due to constant inflow of oxygen can be prevented, and accordingly the quality of the food is guaranteed. By means of the method, an oxidization preventing household food storage machining machine is produced. Refrigerators,food vending machines, food preparers, oil presses, beverage preparers and the like are improved into oxidization preventing devices. Through an oxidization preventing goods shelf, an anti-oxidization food containing barrel tank container, an oxidization preventing food bag and the like, the purpose that people fight with food oxidization for a long term and expect to own a series of food oxidization preventing devices is achieved through the method.
