New Longan Fresh-keeping Technology
From the just-concluded Longyan Fair in Tongan District in Xiamen, it was learned that a brand-new longan preservation technology has been researched and matured. The personage inside course of study thinks: If this preservation method can be successful, it will be a revolution of longan preservation technology, which will open a good situation for longan sales. It is understood that this preservation technology is brought by Taiwan businessman Chen Weiting and its partners, and it is called the "innovation dynamic preservation logistics system." It has two methods of preservation, one is wet preservation. It is the use of a refrigerated container that looks like a container and puts the freshly picked longan directly into the refrigerator. This type of refrigerator is like a small ecosystem. Fresh dragon eyes will “sleep†when they enter the cabinet. At the same time, they can also realize functions such as replenishing water. When you wait for food, the fresh fruit is awakened, just as fresh as just picked. According to reports, using fresh-keeping methods, the fresh-keeping period of up to 50 days, and after the release of preservation, the longan can remain unchanged for two or three days. Another kind of preservation technology is called "dry preservation method", which mainly uses the principle of vacuum dehydration. Traditional longan drying, longan flesh turn yellow, taste will change. The use of vacuum dehydration "Dry Longan" is divided into three types: one is 100% dehydration, this longan dry one shot is powder, just like crisp; one is dehydration 20-30%, this longan dry Crystal clear, can be eaten as fresh fruit; there is a dehydration of 80%, similar to the shape of the traditional dried longan, but this kind of dried longan can maintain umami.
