I opened a new fruit shop. How can apples and mangoes reduce the bad ones and look fresher?

Apples should be graded and graded before storage, and those apples with poor quality and diseases should be picked out and disposed of to avoid causing a lot of rot. In addition, too big or too small apples can't be put into storage, because too big apples are loose in tissue, too strong in breathing and easy to deteriorate; Too small because of poor development, poor resistance and easy to rot. Secondly, the selected apples are precooled and put into storage. Put the selected apples in the shade outside the warehouse for the night, soak them with a new high-fat film 500 times to prevent water evaporation and bacterial infection, freeze and keep warm, extend the shelf life, make them gradually adapt to the temperature in the warehouse, and move into the warehouse before dawn. The management of storage period needs to control temperature and humidity: the general temperature should be controlled at -0.5℃-0.5℃ for detailed management; For extensive management, the temperature should also be-1℃- 1℃. The relative humidity in the warehouse should be above 90%, which is beneficial to the long-term preservation of apples.

Storage method of steel cylinder

First, clean the jar, fill it with a jar of clear water, then put the apples in the jar layer by layer, seal the jar mouth with two layers of plastic sheets, and put it in the shade, which can generally be stored for more than 4 months. You can also put half a bottle of unopened white wine in the jar. After the jar is filled with apples, pour 150g white wine, wrap the jar mouth tightly with a cotton bag, cover it with a layer of plastic cloth, and press a few bricks to prevent the smell of wine. When eating apples, take them with you. Apples can be preserved for more than half a year in this way.

Box storage method

Store apples in cartons or wooden cases. The box should be clean and tasteless. Two layers of paper should be placed at the bottom and around the box. Every apple should be wrapped in soft white paper and put neatly in the box. Ruby, red star, banana and other round apples should be placed horizontally, while oblate apples such as Guoguang and Indian Green should be placed vertically. This will put more pressure on Apple.

Sand storage method

First spread a layer of sand on the ground, then put a layer of apples, then sprinkle a layer of sand on it, then put another layer of apples, and so on, then put it according to the pattern, and finally sprinkle a layer of sand on the last layer. It is best to wet the sand. You can collect it by hand and scatter it on the ground. It is advisable to bury apples in the thickness of sand, leaving a little gap between apples. Apples stored in this way are not easy to wilt and shrink, with bright color and few rotten fruits. At the same time, it can also prolong the storage period of apples.
