There are two ways to deal with jellyfish: 1 is the freshwater method: eating jellyfish with cold water is a good idea, otherwise it will cause "jellyfish poisoning", diarrhea, vomiting and other symptoms. The parahaemolytic bacteria attached to jellyfish are most sensitive to acid, and will usually die after being immersed in vinegar for 5 minutes, and it is difficult to survive in fresh water.1 The fresh water treatment method is to put the jellyfish in fresh water and soak the jellyfish for two days; cut them up and then soak them in vinegar for more than 5 minutes before eating them so that all the isolated bacteria can be killed. Such jellyfish will be safe. 2 is to use salt to kill the method: use salt to rub jellyfish skin, so that the jellyfish skin inside the coarse salt and the strange flavor to rub off very quickly, and then cleaned with water, and then rubbed again, repeated 2 times, eat raw jellyfish skin, there is no obvious astringent flavor can not be smelled originally the kind of fishy flavor, is considered to be handled well. It is best to soak in salt water for a while, so it is better. Jellyfish is a large edible jellyfish that has been eaten as early as the Jin Dynasty, more than 1,600 years ago. China from the Liaodong Peninsula up to the coast of Guangdong are distributed, jellyfish is an important fishing object in China's coastal fisheries.
