"Jellyfish" belong to the coelenterate in the sea. The umbrella part bulges in the shape of a steamed bun, with a diameter of more than 50 centimeters, and the largest one can reach more than one meter. Its glue is relatively hard. After fishing from the sea, the usual color is bluish blue, and the tentacles are milky white. They are widely distributed in the north and south seas of our country. Jellyfish can be eaten or used as medicine.
"Jellyfish" are extremely rich in nutrients. It has been determined that every 100 grams of jellyfish contains 12.3 grams of protein, 4 grams of carbohydrates, 180 mg of calcium, 130 micrograms of iodine and multiple vitamins. In addition to its high nutritional value, jellyfish is also a good medicine for treating diseases. Motherland medicine believes that jellyfish have the effects of clearing heat and detoxifying, resolving phlegm, lowering blood pressure, and reducing swelling. It is said in "Gui Yan Lu":"Jellyfish are a wonderful medicine. They can disperse qi and phlegm, reduce inflammation and eat without harming healthy qi.

I thought, maybe the jellyfish head was more delicious and delicious than the jellyfish skin, so the price would naturally go up with more people buying it. In addition, the net yield of jellyfish head is higher than that of jellyfish skin after being scalded with boiling water. However, the jellyfish skin tends to be empty after being scalded for a long time, and it will not even be half of it. For example, it is unsanitary not to use boiling water to scalm during eating and processing, because the salt-tolerant microorganisms in the sea are very powerful. Once you eat it, it is difficult to get sick, so it is safer to eat it after scalm. But now many restaurants do not scalm it in order to make money. This can reduce costs and look very rich when placed on the table. In fact, it is very unsanitary!
