How can walnuts be preserved for a long time?

Nuts can be stored in film tents, refrigerators and freezers for a longer period of time.

1, movie account storage. Walnuts can be kept for a long time in plastic film curtains. Choose 0.2 mm to 0.23 mm thick polyethylene film to make the account. Then, seal the dried walnuts in the account and store them. The oxygen content in the account should be below 2%.

2. Refrigerator storage. If the storage capacity is not large, nuts can be sealed in polyethylene bags and stored in the refrigerator at 0℃ to 5℃, which can maintain good quality for more than two years.

Step 3 refrigerate. Where conditions permit, large quantities can be packed in gunny bags and stored in low-temperature cold storage at 0℃ to 1℃, with better effect.
