When stored, it is mainly kept dry. Generally, it can be stored in the refrigerator in summer and at home at room temperature in autumn and winter. I once published an academic paper. The nutritional changes of walnuts stored at room temperature and in the refrigerator for one year are obviously different, and the rancidity degree of walnuts in the refrigerator is much lower than that at room temperature.

Generally, you can't eat too many dried fruits at a time, which will lead to acidosis and sometimes some rashes. It is recommended to eat two or three at a time. Walnut has a good brain tonic effect. In addition, it can also prevent hair loss, improve hair quality and blacken hair, with many benefits.

Raw walnuts are best put in a bag. Be careful not to let the water in the bag run off when loading. Secondly, it is best to use a higher sealing performance.

After being installed, it can be placed in the freezer of the refrigerator, because the freezer of the refrigerator has good refrigeration effect and will not make walnuts oxidize quickly.

Extended data:

Trench storage method: dig a trench with a depth of 1m, a width of 1- 1.5m and a length depending on the storage capacity at a place with high terrain, good drainage and shade. A layer of clean wet sand with a thickness of 10 cm should be paved at the bottom of the ditch, and the humidity of the sand should be rubbed by hand, but no water can come out. Then spread a layer of walnuts and a layer of sand, and fill the ditch wall with wet sand, leaving no gaps. When it is spread to a distance of about 20 cm from the gully mouth, the wet sand is covered to be flush with the ground, and the soil on the sand is roof-shaped, with a span greater than the width. Drains are opened around the ditch to avoid excessive rainwater infiltration, resulting in high humidity and walnut rot. When the ditch is more than 2 meters long, when storing walnuts, a tightly tied straw should be erected every 2 meters for ventilation, and the height of the straw handle should be exposed to the "roof".

Sand storage method: first spread a layer of sterilized rice straw and wheat straw on the ground in a cool room, then spread a layer of wet sand with a thickness of 10 cm, put a layer of walnuts, and then put another layer of sand, with the stacking height not exceeding 1 m and the top layer of wet sand being 20-30 cm thick. Keep the top sand moist during storage.
