The shelf life of laver is generally 12 months. Dried laver with packaging bags should be eaten as soon as possible after opening. If it is inedible after opening, it should be kept in a ventilated and dry place. Generally, it can be stored for 1 month, but it will not deteriorate within one month. If it takes more than a month, it may not be necessary. In addition, dried laver should be kept away from humidity and high temperature, and of course it can also be sealed and stored in the refrigerator to extend the shelf life.

Preservation method of laver: Generally speaking, dried laver should be placed in a dry place to avoid moisture, because dried aquatic products are very easy to absorb moisture, regain moisture, go moldy and deteriorate, and even breed bacteria in a humid environment. It should be packed in a black food bag, placed in a low-temperature dry place, or placed in a refrigerator to preserve its taste and nutrition.
