How to keep litchi fresh when you buy it? Cut off the long branches of litchi, then put the litchi into a plastic bag, tie the bag tightly and put it in the shade. If conditions permit, the plastic bag containing litchi can be immersed in water. In this way, the color, fragrance and taste of litchi will remain unchanged after a few days. It should be noted that fresh lychees should be selected for long-term preservation.
Folium Artemisiae Argyi is also effective for prolonging the storage time of litchi, because Folium Artemisiae Argyi has bactericidal and antiseptic effects. In addition, the heating exhaust method is also a good storage method. Firstly, put the pulp into a jar, add sugar water, then put it into an exhaust box for heating and exhausting, then seal the jar, boil it in boiling water, and cool it to get the canned lychee with sugar water. Bacteria can't survive because of high temperature treatment. This provides a new method for litchi preservation.
You can also keep it in the refrigerator. Litchi can be kept fresh for no more than one week at room temperature, and the shelf life can be extended by about one month at low temperature. If it is sold, it is feasible in time. But it can only be kept at-18℃. Cryopreservation is the best way to help us prolong the service life of litchi. It is also a very good way to store litchi in fresh-keeping cartons. A sealing film can be coated on the surface of litchi, which can prevent oxygen from entering fruits and vegetables, prolong the aging process of litchi and increase the fresh-keeping time of litchi.
Short-term preservation method
First, litchi should be preserved for a few more days without discoloration and deterioration. You can cut off the long branches of litchi first, then put the litchi into a plastic bag, tie the bag tightly and put it in a cool place. If conditions permit, the plastic bag containing litchi can be immersed in water. In this way, the color, fragrance and taste of litchi will remain unchanged after a few days. It should be noted that fresh lychees should be selected for long-term preservation.
Second, in order to preserve the color and fragrance of litchi, you can spray some water on litchi, put it into plastic fresh-keeping bags and put it in the refrigerator, and store it at low temperature and high humidity (2-4 degrees Celsius, humidity 90%-95%). Squeezing out the air in the bag as much as possible can reduce the oxygen ratio to slow down the oxidation speed and improve the preservation effect.
Can litchi be frozen in the refrigerator?
Litchi is best placed in the fresh-keeping area, not in the frozen area, which will spoil the ice. Put it in the refrigerator, but it will? Frostbite? Litchi peel will darken in color, and some spots like burns will appear in the endocarp, so it is often inedible. In addition, if litchi is left at 0℃ for one day, the skin will turn black and the pulp will turn sour.
Litchi at 7℃? It can be stored at 10℃ for one week and in the refrigerator for about one month.
