Preface: Seaweed is rich in nutrients and can also be used to stew soup. When we buy dried seaweed in the market, it is often purple, but after the soup is stewed, it turns green. Many people doubt it. I bought fake seaweed, but it is not actually like this. Because seaweed is rich in phycoerythrin, phycoerythrin is unstable and will decompose when exposed to heat. After decomposition, it will turn into chlorophyll and lutein. The content of chlorophyll is relatively high, so it appears green, which is a very normal phenomenon. 1. Normal phenomenon

If we find that the seaweed has turned green, we don’t need to worry too much. This is a very normal phenomenon. Therefore, in your daily life, you can watch more popular science videos or read corresponding books, so that you can gain some knowledge and understand normal phenomena. After phycoerythrin is decomposed, it becomes chlorophyll and lutein. Because the content of lutein is not as high as chlorophyll, it is said that seaweed turns green after being stewed. 2. It’s not fake seaweed

Many people like to make tomato and egg soup. In the process of making soup, some seaweed will be added. The content of dried seaweed is relatively high and rich in iodine, which can prevent big neck. sick. In some iodine-deficient areas, you can eat more seafood, except seaweed. We can also eat some kelp. If we find that the seaweed turns green after cooking, we should not doubt that we have bought fake seaweed. The production process of seaweed strictly complies with national standards, and we can use it with complete confidence. 3. Use it with complete confidence

The taste of seaweed is very good. When we make soup, we only need to take out a little dry seaweed, and it will turn into many vegetables after washing. Then during the process of cooking seaweed soup, we can also add some other seasonings to make the whole pot of soup taste more delicious. For some elderly people, they have never seen such a situation and feel that this kind of seaweed cannot be used. We can educate them about it.
