Problems solved by technology

But the maturation period of longan and litchi is too concentrated, and it is not resistant to storage, which makes people only enjoy its fresh and delicious taste in the harvest season of longan and litchi. It is not easy to eat fresh and delicious longan and lychee
On the other hand, the ripening season of longan and litchi is usually from May to October. At this time, it is in hot summer and the temperature is quite high. After the fruit is picked from the tree, it can only be stored for 3 to 5 days. It began to turn black and harden, and the quality began to decline until it became corrupt. Because the harvesting time of longan and lychee was too concentrated, the harvesting time was short, and it was difficult to store, the fruit farmers had to sell at a reduced price, which greatly reduced the economic income of the fruit farmers. , affecting the enthusiasm of fruit farmers to produce
For this reason, people have adopted fresh-keeping technology to longan, litchi to be kept fresh, and people can eat fresh and delicious longan, litchi in different places, different seasons, and the fresh-keeping technology of prior art longan, litchi usually adopts medicine preservation or freezing Freshness preservation, whether it is the former or the latter, can play a certain role in freshness preservation, but the preservation period of the existing freshness preservation technology is short, and the preservation effect is not satisfactory. The color and taste of the fruit shell after preservation are different from fresh fruits , which has greatly affected the sales market of fresh fruits, and affected people's desire to eat fresh fruits.
