Kelp grows on rocks at a depth of 2 m below the low tide line of the seashore and is farmed on ropes or bamboo. Kelp belongs to the subarctic algae.

It is endemic to the North Pacific Ocean, and there is some kelp in the Atlantic Ocean.

Most kelp is found in the northern hemisphere, but also in small quantities in the southern hemisphere, and generally grows on subtidal seafloor rocks. The growth of kelp is mainly affected by factors such as temperature, light, nutrients and plant hormones.

Many families have some dried kelp stored and are not in a hurry to eat it. Some believe that it can be stored for long periods of time, just like other seafood.

In fact, the kelp purchased by ordinary families is mainly light and dried kelp, and its shelf life is generally half a year to one year.

Therefore, after buying kelp, you should eat it as soon as possible. If you can't eat it all, you should refrigerate the unsealed kelp in the refrigerator or freezer, because the unsealed kelp will be affected by temperature, light and other factors during storage, and its nutrients will be degraded. On the contrary, microorganisms will continue to multiply, and harmful components will also increase, all of which will cause kelp to spoil and become inedible.

When eating kelp, it should be cleaned and soaked in water according to the actual situation, and the water should be changed continuously, generally soaking for more than 6 hours. If the kelp is not as tough as if it was boiled after soaking in water, it has gone bad.
