The nitrogen monoxide gas is filled into the fresh-keeping space, so that the original relative proportion of nitrogen and oxygen in the fresh-keeping space is not influenced. In a preferred embodiment, the gas storage means 30 for providing nitric oxide gas to the fresh space may be a nitric oxide gas storage tank.
The refrigeration and freezing apparatus 100 further includes: the gas content sensor is arranged in the fresh-keeping space to detect the actual content of nitric oxide in the fresh-keeping space. The gas atmosphere beneficial to food preservation comprises: the actual content of nitric oxide is 5 mu L/L to 10 mu L/L. The amount of nitric oxide gas provided to the fresh-keeping space by the gas storage device 30 is related to the volume of the fresh-keeping space, and the larger the fresh-keeping space is, the more nitric oxide needs to be provided; the smaller the fresh-keeping space is, the less nitric oxide needs to be provided, but the nitric oxide content in the final fresh-keeping space is in the range of 5 mu L/L to 10 mu L/L so as to ensure the fresh-keeping effect of the stored food in the fresh-keeping space.
Nitric oxide is favorable for food materials to secrete hormone, especially growth hormone, and when the secretion of the growth hormone is vigorous, the viscera, muscles and bones of the organism can be well updated. Nitric oxide also plays a central role in other physiological processes, such as: regulate apoptosis of cells, influence metabolism of endogenous ethylene in vegetables, regulate and control respiratory intensity of leaf surface air holes, and the like. Therefore, the nitrogen monoxide is provided for the fresh-keeping space, which has important significance for preventing the decay of the food materials, obviously inhibits the respiration of the food materials, reduces the loss of nutrient substances in the storage process, prolongs the fresh-keeping period of the food materials, and can improve the fresh-keeping effect of various food materials.
The inventor finds that under the condition of a certain refrigerating temperature, such as 2 ℃, food materials, such as fruit and vegetable food materials, are stored in a fresh keeping space through a plurality of experiments. By providing different amounts of nitric oxide gas to the fresh keeping space, the nitric oxide content in the fresh keeping space is different. Under the conditions of the same temperature and different nitric oxide contents, when the nitric oxide content in the fresh-keeping space is in the range of 5 mu L/L to 10 mu L/L, the modified atmosphere fresh-keeping effect of the food material is optimal. For example, under the common refrigeration condition, the apple is kept fresh for 10 days, and when the nitric oxide content is 5 mu L/L, the modified atmosphere is kept fresh for 30 days; under the common refrigeration condition, the peach is kept fresh for 7 days, and when the nitric oxide content is 5 mu L/L, the modified atmosphere keeping time is 30 days; under the common refrigeration condition, the fresh-keeping time of the strawberries is 3 days, and when the nitric oxide content is 10 mu L/L, the controlled atmosphere fresh-keeping time is 15 days; under the common refrigeration condition, the fresh-keeping time of the green peppers is 5 days, and when the nitric oxide content is 5 mu L/L, the air-conditioning fresh-keeping time is 15 days; under the common refrigeration condition, the preservation time of the tomatoes is 7 days, and when the nitric oxide content is 5 mu L/L, the modified atmosphere preservation time is 20 days; under the common refrigeration condition, the mushroom is kept fresh for 7 days, and when the nitric oxide content is 10 mu L/L, the controlled atmosphere keeping time is 20 days; the fresh-keeping time of lettuce under the common refrigeration condition is 6 days, and the modified atmosphere fresh-keeping time is 25 days when the nitric oxide content is 5 mu L/L. The nitric oxide content intervals can be thinned and distinguished according to different types of food materials, and the fresh-keeping effect of various food materials is further improved.
The temperature in the fresh-keeping space is kept in a certain range while nitric oxide gas is provided for the fresh-keeping space, so that the fresh-keeping effect of the food can be assisted to be improved. Different food materials can be corresponding to different proper storage temperatures, for example, the refrigerating temperature of fruit and vegetable food materials is generally 2 ℃ to 8 ℃, the refrigerating temperature of chilled fresh meat food materials is generally-2 ℃ to 1 ℃, and the freezing temperature of various food materials is generally-22 ℃ to-14 ℃. The fresh-keeping effect of various food materials can be effectively improved by providing a certain amount of nitric oxide gas for the fresh-keeping space and keeping the temperature in the fresh-keeping space in a proper storage temperature range of the various food materials. It should be noted that the specific values of the above storage temperatures are only examples, and are not limiting to the present application.
The pipeline switching mechanism 32 is driven to be communicated with the pipeline from the outlet end of the gas storage device 30 to the fresh-keeping space, and can be manually completed by a user, for example, when the user puts food into the fresh-keeping space, the air-conditioning fresh-keeping function is started, the pipeline from the outlet end of the gas storage device 30 to the fresh-keeping space is communicated by the pipeline switching mechanism 32, when the nitric oxide content in the fresh-keeping space reaches 5 mu L/L detected by the gas content sensor, the user is reminded to close the air-conditioning fresh-keeping function by outputting prompt information, so that the user closes the pipeline from the outlet end of the gas storage device 30 to the fresh-keeping space by using the pipeline switching mechanism 32, and the prompt information can be alarm sound sent by the buzzer. In other embodiments, automatic setup may also be performed, with the tubing switching mechanism 32 configured to: after the triggering operation of putting the food material into the container by the user is obtained, the pipeline from the outlet end of the gas storage device 30 to the fresh-keeping space is automatically communicated, and when the nitric oxide content reaches 5 mu L/L, the pipeline from the outlet end of the gas storage device 30 to the fresh-keeping space is automatically closed, and the triggering operation of putting the food material into the container by the user can be the opening operation of the sealed drawer. The nitric oxide content reaching 5. Mu.L/L is not limited to the present application, and in other embodiments, the nitric oxide content may be set within an optimal range of 5. Mu.L/L to 10. Mu.L/L according to the type of food.
