Suitable for long-distance sales of fresh air modified atmosphere, not all kinds of fruit are applicable. Our study found that during the storage of fresh fruit, bayberry has high respiratory intensity and releases a large amount of ethylene, which promotes fruit senescence and rot. In this regard, by reducing the temperature, changing the proportion of gas, reducing respiratory consumption, and removing harmful constituent gases, it is possible to delay the aging period and achieve the purpose of prolonging the storage and preservation. The operation technology of fresh air conditioning and preservation is based on the preservation of low temperature. Its fruit selection, pre-cooling, loading and transportation are similar to those of cryogenic storage and transportation. Only when the packing operation is completed, the fruit is filled in the film bag to just above the opening of the foam plastic box, and then it is sprayed and preserved on the top surface. Agents, generally do not have to spray up and down the entire box. At this point, the air in the plastic bag was started to dry out the plastic bag, and then nitrogen gas was injected. The air pumping and air pumping were repeated several times and the bag was sealed immediately after the proper ratio of inert gas and oxygen was achieved. Sealing requirements are tight, so that the gas in the bag is completely isolated from the outside world, so that the proportion of the gas in the bag is not affected by the external gas. Afterwards, cover the lid and compact it, seal the gap between the lid and the box with adhesive paper, and use the same adhesive paper to fix the lid and transport it immediately. The above-mentioned is a small-package modified atmosphere fresh-keeping, which is 2 times longer than the general low-temperature preservation and preservation period. If the operating specifications are strict, the fresh-keeping period can reach 20 days. The general cold preservation period is only 7 days. Compared with ordinary cold storage, fresh air conditioning can significantly extend the shelf life and improve the preservation quality. The reason is that under the conditions of increasing nitrogen and reducing oxygen, not only the respiration is weakened, the sugar loss is reduced, but also the production of ethylene is reduced and delayed Fruit senescence, while inhibiting the proliferation of microorganisms, can prevent mildew and maintain good quality of fresh fruit. During the period from June to July, the quality of Yangmei in most cities across the country was out of stock. The Yangmei area in Zhejiang Province used the above measures to successfully transport Yangmei to cities in northeast, north, and northwest China. The method is simple, low in cost, effective, and effective. The actual conditions of the majority of bayberry production areas will inevitably be used in a large number of bayberry production areas in long-distance transportation and sales. It will play an important role in solving the off-season fruit supply and increasing the income of farmers.
Fruit and Vegetable Powder
