It can be understood that the preservation container 10 is used as a space separately set up in a refrigerating chamber or a freezing chamber, which not only can save energy, but also can prevent the food materials in the preservation container 10 from being tainted with the food materials not placed in the preservation container 10.
Referring to fig. 2 and fig. 3, fig. 2 is a schematic structural diagram of a container body according to an embodiment of the present disclosure. Fig. 3 is a schematic structural diagram of a freshness retaining container according to an embodiment of the present application.
The freshness retaining container 10 comprises a container body 11, a modified atmosphere device 12, a magnetic field generating device 13, a sensor 14 and a control device, wherein the container body 11 has a cavity 111, the modified atmosphere device 12 is arranged in the cavity 111, and the modified atmosphere device 12 is configured to adjust the gas composition in the cavity 111 so that the gas composition in the cavity 111 is different from the composition of air, thereby inhibiting physiological and biochemical processes causing deterioration and activities of microorganisms. It is understood that, normally, the composition of air is about 78.1% nitrogen (N2), about 20.9% oxygen (O2), about 0.939% rare gases, and about 0.03% other gases and impurities. Under such normal conditions, physiological and biochemical processes and activities of microorganisms causing deterioration exist in the food material, but if the gas composition in the cavity 111 is adjusted to a composition different from that of air, for example, the oxygen concentration is 5% to 10%, the carbon dioxide concentration is 8% to 20%, and the remaining gas is nitrogen, the physiological and biochemical processes and activities of microorganisms causing deterioration are inhibited. The gas-modified preservation device 12 works on the principle of adsorbing oxygen and discharging carbon dioxide, so that the gas composition in the cavity 111 changes.
Wherein, the cavity 111 is also provided with a magnetic field generating device 13, the magnetic field generated by the magnetic field generating device 13 can change the metabolism mechanism of the microorganism, reduce the relative expression level of the synthetic gene segments of bacteria, mould and mycotoxin, effectively inhibit the generation of the microbial toxin, thereby realizing the aim of magnetic field fresh-keeping.

For example, the preset values may be an oxygen concentration of 5% to 10%, a carbon dioxide concentration of 8% to 20%, and the balance nitrogen. For another example, the weak intensity is 0mt to 10mt, and the high intensity is 10mt to 50 mt.
The fresh-keeping method comprises the following steps:
step (1): when the freshness container 10 is detected to be opened, the modified atmosphere preservation device 12 is activated.
Step (2): the modified atmosphere preservation device 12 monitors the gas composition, and whether the gas composition is a preset value or not.
And (3): when the gas components are not the preset values, the control device controls the intensity of the magnetic field generated by the magnetic field generating device 13 to be high intensity and starts the controlled atmosphere preservation device 12; when the gas component is a preset value, the control device controls the magnetic field intensity generated by the magnetic field generating device 13 to be low intensity.
And (4): and (3) turning to the step (2) until the gas components are preset values.
For example, when the user opens the freshness retaining container 10 and the sensor 14 detects that the gas in the cavity 111 becomes a preset value, the control device controls the air-conditioning device 12 to start to operate and controls the intensity of the magnetic field generated by the magnetic field generating device 13 to be high intensity, for example, 10mt to 50 mt; when the sensor 14 detects that the gas in the cavity 111 is a preset value after the user closes the freshness retaining container 10, the control device controls the gas-conditioning device 12 to stop working and controls the intensity of the magnetic field generated by the magnetic field generating device 13 to be low, for example, 0mt to 10 mt.
