How to preserve Sargassum dentatum for a long time?

Fresh purslane can be sealed with plastic wrap and stored in the freezer of the refrigerator, so the storage time should not be too long, and it can be eaten in a few days. It can also be stored directly for 3 days. Another way is to dry in the sun and soak in hot water when eating. This method is simple and direct, but it depends on the weather. Plan the drying time and don't choose to dry in unpredictable weather. Make sure the sun is in the sky for the next few days. It will take 4-7 days to dry in this weather. Basically, the water in purslane has evaporated. Just scald it in salt water for a few minutes, then drain it and expose it to the sun.
