Extended data:
Kelp contains fucoidan and alginic acid. Once water is absorbed, sticky colloid will appear on the surface of kelp, which will prevent water from further immersion and make it difficult to cook. In addition, water-soluble vitamins, minerals and other nutrients in kelp will also be soluble in water, and long-term soaking will reduce the nutritional value.
The soaking method of kelp should be steaming first and then soaking. Put kelp in a steamer, dry steam it for half an hour, and then soak it in water for two or three hours. Or put a little alkaline noodles or baking soda before steaming, so that kelp gum can be easily dissolved by alkaline substances and will soften quickly when cooking.
Put some vinegar in the water, or soak it in rice washing water, which can make kelp soft quickly; You can also add some spinach when cooking, because spinach contains a substance called oxalic acid, which can also make kelp soft quickly.
