Can soaked seaweed be frozen

Seaweed soaked in water can be frozen and stored, but it is recommended to consume it as soon as possible to ensure optimal taste and nutrition. The texture of kelp may become soft after freezing and thawing, which is suitable for stewing or Congee. Kelp is rich in iodine, dietary fiber, and minerals. During the freezing process, there is less loss of nutrients, but repeated thawing can cause damage to cell structure. Short term freezing can inhibit microbial reproduction and extend storage time to about a month. If long-term storage is required, it is recommended to divide the kelp into small portions and seal them to avoid repeated freezing and thawing of the whole piece. Drain the water before freezing and wrap it with plastic wrap to reduce the damage of ice crystals to the tissue.

Some instant kelp products are not suitable for freezing due to the addition of preservatives, and products labeled as requiring refrigeration storage on the packaging may experience delamination and spoilage after freezing. After freezing, the saltiness of salted kelp will be concentrated, and it needs to be fully soaked and desalinated before cooking. If the surface of the thawed seaweed becomes sticky or emits a strange odor, it should be immediately discarded and not eaten.

It is recommended to soak seaweed in moderation according to your needs and avoid hoarding in large quantities for daily consumption. When cooking frozen kelp, it can be directly put into the pot without thawing, and high-temperature heating can effectively kill potential bacteria. Stewing with ingredients such as tofu and radish can enhance freshness and promote iodine absorption, but thyroid disease patients need to control their intake.
