Kelp stewed ribs, kelp stewed tofu... The appearance rate of kelp on our table is very high, and many people are curious, why do some kelp have to tie a knot?

Kelp knotting mainly has the following purposes, one is to cook a non-stick pan. Kelp is rich in soluble seaweed gum, which is easy to stick to each other, and if you are not careful, you may cook paste, stick to the bottom of the pot, and it is not easy to clean. Tying a knot is a good way to avoid this situation. The second is to facilitate clamping. After the kelp is cooked, the surface is very slippery, it is not easy to separate it with chopsticks, and it is difficult to tie a knot in advance, which can be non-slip and easier to clip. In addition, kelp piled together can also affect the taste.

In addition to seaweed gum, kelp is also rich in minerals such as iodized potassium, calcium and magnesium and dietary fiber, which can be eaten regularly to prevent iodine deficiency goiter and also has a certain preventive effect on colorectal cancer. Soluble dietary fiber in kelp helps lower lipids, sugar, and blood pressure, and to a certain extent helps to expel heavy metal toxins from the body. Need to remind everyone, the normal kelp should be yellow-brown or dark brown, there are some colors of turquoise kelp on the market, known as fresh kelp, may be dyed, it is best not to buy. ▲
