1. You can soak it in cold water. However, because the iodoacetic acid and mannitol in kelp can be dissolved in water, if the dried kelp is soaked in water for more than several hours, about 90% of the iodoacetic acid will be lost. , mannitol is also mostly dissolved, which may reduce the nutritional value of kelp.

Dried kelp often has a layer of white powder like frost attached to it, which makes people feel unclean, and they always want to try their best to scrub it clean. In fact, this layer of white powder is an organic compound "mannitol" that people are not familiar with, and it is a valuable medicinal substance.

2. There are many ways to soak kelp:

Soak kelp in rice water in advance; or add a little (but not too much) edible alkali or baking soda when cooking kelp. After boiling, soak the kelp in cold water, clean it, and then take it out for consumption. Or you can open the balls of dried kelp and put them in a basket with water to dry-steam for about half an hour, and then soak them in water overnight. This can make the kelp not only crispy and tender, but also soft and delicious.
