3. When fresh litchi fruit is placed in a sealed container, due to the respiration of litchi itself, carbon dioxide is released. The oxygen in the container is less and carbon dioxide is increased, which will spontaneously form a storage environment with low oxygen content and high carbon dioxide content. The quality of litchi can be preserved for 30 days at low temperature of 1 ℃ - 9 ℃ and 6 days at normal temperature with little change. The vitamin content in litchi is slightly reduced, but the flavor is not affected.
