Abstract

An antistaling technique for fresh litchi features that after the fresh litchi fruits are stored at -30-10 deg.C for 0.3-360 days in the condition of isolating air by vacuumizing, filling antioxidizing gas, immersing in liquid, coating liquid, or gelatinizing by liquid or colloid, they are heated to ordinary temp.

Description

technical field [0001] The invention relates to fresh litchi preservation technology in the technical field of food preservation. technical background [0002] In the prior art, the preservation time of fresh lychees is extremely short. The fresh lychees in the market are put on the shelves in the morning, but in the afternoon they change color and are no longer fresh. The fresh lychees bought home will go bad in at most three days and can no longer be eaten. With the best fresh-keeping technology, the fresh-keeping period is only ten days and a half months. In addition, fresh lychees are a kind of hot food. Eating lychees in hot summer is very easy to get angry, so many people will have toothache or nosebleeds when eating fresh lychees. Fresh lychees are a tonic, and eating fresh lychees in winter can nourish the body. Since fresh lychees cannot be kept fresh, once the lychee picking season is over, there will be no fresh lychees for sale on the market, so only dried ly...
