Low-temperature fruit and vegetable marketing is a common method in some developed countries and regions. People know from daily life that winter fruits and vegetables are better stored than in summer, and northern regions have relatively low temperatures for most of the year. Therefore, northern fruits and vegetables are stored longer than the south. Using low temperature storage or transportation of fruits and vegetables is a method of artificially imitating nature. If you have a refrigerator at home, you will experience it. So why can low temperature have such a role? Low temperature has an impact on everything that is inanimate or alive, which can reduce consumption and extend life. For fruits and vegetables, low temperature has the following effects: First, the low temperature reduces the breathing of fruits and vegetables, making the life of fruit and vegetables slow. Because of the reduction in internal friction, the life span has been extended. Low temperatures also limit the internal ethylene production in fruit and vegetables, which greatly delays the maturation and aging of those fruit types with respiratory transition. Second, low temperatures can maintain high relative humidity in the air, which can also slow down the evaporation of water on the surface of the vegetables and keep the fruit and vegetables fresh and full. Third, the low temperature also limits the pathogens that harm fruits and vegetables, making it difficult for the bacteria to move. When the mud bodhisattvas cross the river, they are unable to protect themselves, and they will do less harm to the fruits and vegetables. Therefore, under low temperature conditions, the incidence of fruit vegetables is less, and the decay naturally decreases. Since the low temperature can play a role from the above three aspects, compared with the normal temperature, the low temperature storage and transportation can greatly extend the preservation time of fruits and vegetables. Here, it is worth mentioning that low-temperature preservation, completely imitate the natural methods, with the least chemical drugs, there is no residue, pollution problems exist, with fresh fruit and vegetables at low temperature, people can rest assured that eating.
