laver needs washing.

Porphyra will inevitably accumulate dust during the production, transportation and storage, so it is very necessary to wash it with water before eating. Laver can't be cleaned for too long, just wash away the floating dust on the surface with clear water quickly, and don't soak it in water. In the process of washing, colander and other instruments can be used to assist the operation.

Precautions for preservation of dried 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. It should be packed in a black food bag and placed in a low-temperature dry place, or put in a refrigerator to keep its taste and nutrition.
