Application of modified atmosphere packaging 4
Modified atmosphere fresh-keeping packaging of fresh fruits and vegetables
After harvesting, fruits and vegetables can still maintain the metabolism of absorbing oxygen and discharging carbon dioxide, While consuming nutrients. Fruit and vegetable preservation is achieved by reducing the environment, content and low temperatureStorage reduces the progress of respiration and eliminates the CO2 produced by respiration to delay the ripening and aging of fruits and vegetables to achieve the effect of preservation.
The modified atmosphere packaging gas of fruits and vegetables is composed of oxygen, carbon dioxide and nitrogen. Pack the fruits and vegetables with a breathable film, fill it with low oxygen and replace it with high carbon dioxide and mixed gas, then seal, so that the oxygen content in the package is lower than air and the accumulated carbon dioxide is higher than air. The gas exchange is carried out through the thin film to achieve an atmosphere balance that is conducive to the preservation of the fresh environment of fruits and vegetables and maintains the weak aerobic respiration.
