How to preserve red dates?

Jujube is afraid of wind, high temperature and humidity. It is easy to dry and shrink after being exposed to the wind, and the skin color changes from red to black; High temperature and humidity are easy to produce pulp, and insects are moth-eaten and moldy. Preservation method: you can expose yourself to the sun four or five days before Qingming. In order to prevent blackening, you can cover the jujube with a summer mat or lay it in a ventilated and cool place for a few days. After airing thoroughly, put it in a jar, cover it with wood or mix it with plant ash, and cover it in a bucket. You can also use 30 grams to 40 grams of salt, stir-fry and grind it into powder, sprinkle it on 500 grams of red dates in layers, and then seal it, so that red dates will not go bad. The best formula for controlling jujube pests is 1. Boiling water treatment. Blanch jujube with boiling water once, then take it out quickly and dry it in the sun, which can kill the bacteria on the surface of jujube and store it in a dry and moisture-proof sealed container to avoid moth-eaten and jujube deterioration. 2. Salt "standing guard" method. Take a sealed ceramic container with a lid, wash it and dry it for later use. After putting a layer of red dates in the container, put a thin layer of refined salt until all the red dates are put in, sprinkle a layer of refined salt on the top layer of red dates, and then cover and seal. Because eating refined salt has the function of sterilization and preservation, it is like a sentry, and because sweet food can be sweetened with a little salt, these sentries will not make red dates salty.
