1, when eating dried kelp, from the safety point of view, after cleaning, soak it in water according to the actual situation, and constantly change the water, generally soak it in clear water for more than 6 hours. But if it is pollution-free dried kelp with guaranteed quality, don't bother, because the soaking time is too long, the nutrients in dried kelp, such as water-soluble vitamins, iodine, mannitol and inorganic salts, will also dissolve in water, and the nutritional value will be reduced.
2. Dried kelp is a recognized nutrient, and iodine contained in dried kelp is an indispensable trace element for human body. Eating dried kelp is the main supplementary means for people to supplement iodine, but when eating dried kelp, you must eat it in moderation. Don't eat dried kelp as the main course every day, because too much iodine intake will also have an impact on your health.
3. Eat dried kelp as soon as possible after buying it, or store it in a refrigerator with good heat preservation conditions after unpacking, because the unpacked dried kelp will deteriorate with the degradation of nutrients, the reproduction of microorganisms, the increase of harmful components and other reasons during storage. If the dried kelp is as tough as boiled after soaking in water, it means that it has deteriorated and can no longer be eaten.
When we choose dried kelp, the first thing to look at is whether there is white powder on the surface, because kelp is the food with the highest iodine content, and these white material are mannitol with high nutritional value, which is an important symbol of kelp. If not, it is old junk, so we'd better not buy it.
We also need to know this knowledge well, because our diet is an important factor that affects our health. Only by eating healthily can we ensure our health at the most basic level. We should pay more attention to some details in life and pay attention to the color of kelp when choosing kelp. Everything is for our safety and health.
