To understand how to cultivate edible fungi by using chemical methods to keep flowers and fruits fresh.

The preservation of flowers and fruits is to appropriately control the amount of water and gas in order to prolong the aging process and achieve the purpose of preservation.

In the process of storage and transportation of flowers and fruits, they are often placed in certain containers, in which ethylene gas will be released by themselves, and ethylene is a kind of fruit ripening agent, which will accelerate the early ripening of flowers and fruits. This early ripening phenomenon is an important factor in the inconvenience of long-term storage of fruits and flowers.

In order to achieve the purpose of keeping fresh, a relatively simple chemical method can be used to keep it fresh. That is, in the process of keeping fresh, putting some mixture of fine zeolite adsorbed with potassium permanganate and vermiculite in dry bath in the storage container can keep fruits and flowers fresh for a long time. The principle of this method is that the ethylene gas emitted by flowers and fruits can react with potassium permanganate and produce carbon dioxide and water, thus reducing the content of ethylene gas in the storage and reducing its ripening effect. delayed the fruit discoloration, ripening and softening process. On the other hand, the water evaporated from flowers and fruits can be absorbed by vermiculite in the dry bath and can play a role in regulating humidity. Therefore, the combination of the two can achieve the purpose of long-term fresh-keeping.

When fruits and flowers are packed with permeable film, the above antistaling agents can be encapsulated in breathable bags and put into fruit bags, which will also play a good role in keeping fresh. (source: Zhongshan Agricultural Information Network)
