Can jellyfish be eaten? Some jellyfish are edible but require processing

Jellyfish can be eaten, but not all jellyfish are edible. There are not many edible species of jellyfish, and the most common one is the jellyfish (Rhopilema esculentum). The jellyfish (Rhopilema esculentum) is widely distributed along the coast of our country, and after processing it becomes the familiar jellyfish skin and jellyfish head, which are very traditional aquatic food ingredients.

Most jellyfish are not suitable for eating, and the key lies in the cnidocytes. The bell and tentacles of fresh jellyfish are covered with cnidocytes, which release toxins upon contact, and eating them raw may cause stinging, allergies, or even poisoning. Highly toxic species such as box jellyfish and Portuguese man o' war are dangerous whether touched or accidentally eaten, and should be avoided when encountered at the seaside.

Edible jellyfish sold on the market usually must be repeatedly pickled with salt and alum. This process can remove most of the water from the body, deactivate the cnidocytes, and make the texture crisp and elastic. Before eating, it is generally also soaked and rinsed with clean water to remove excess salt and astringency, and then used for cold dressing or cooking.

From a nutritional perspective, jellyfish have a high water content and low fat content, and contain a certain amount of protein and minerals. Cold-dressed jellyfish is a very popular home-style way to eat it. It should be noted that when eating jellyfish, you should buy qualified processed products through proper channels, and never catch or eat raw jellyfish of unknown origin by yourself; people with an allergic constitution should be cautious before eating, and if discomfort occurs, they should stop in time and seek medical attention.
