Why do lychees need ice?

The purpose of freezing litchi is to change the ambient temperature of litchi, thereby extending the shelf life of litchi and maintaining a good taste. Litchi is a tropical fruit, and it will quickly deteriorate and go bad at room temperature in summer after being picked. If litchi is frozen with ice, this problem can be avoided as much as possible.

There are many ways to preserve litchi, such as low-temperature refrigeration, temperature-regulated storage in plastic bags, radiation storage, vacuum storage, nitrogen storage, etc.

Low temperature storage is to pack litchi in plastic bags, place them in turnover boxes or standard cartons, and then place them in a cold storage room with a temperature of 0℃ to -8℃.

Generally speaking, lychees can be frozen, but the taste of frozen lychees is worse than that of fresh lychees, and they can easily go bad after thawing.

Why do we eat lychees during the Great Heat?

Eating lychees during the Great Heat is a custom in Putian, Fujian. Every household in Putian eats lychees during the Great Heat, which is called "going through the Great Heat".

Is litchi shell dry garbage or wet garbage?

Lychee shells are perishable, so they are classified as wet garbage. The gas generated by the decay of wet garbage can be well converted into biogas for use as fuel, and it also plays an important role in protecting the ecological environment.

Many people do not distinguish between wet garbage and dry garbage. Wet garbage refers to garbage that can rot, such as leftovers, expired food, fruit peels and cores. Lychee shells contain moisture and are prone to corrosion over time, so they are considered wet garbage.

Not only lychee shells are considered wet garbage, but all fruit peels and cores are considered wet garbage. Wet garbage can be turned into treasure, and the rotten smell can be used as biogas for use as fuel gas, which is also of great significance to environmental protection.

It is easy to distinguish between dry garbage and wet garbage. Dry garbage refers to all domestic waste except hazardous garbage, recyclable garbage and wet garbage. Wet garbage refers to garbage that is easily corroded.
