2. Eel is also called eel and long fish. Because of its tender meat, delicious taste and rich nutrition, it has the functions of tonifying deficiency, dispelling cold, dredging blood vessels and benefiting bones and muscles, and is deeply loved by people.
3. However, eels contain a substance called histamine acid. Histamine acid is easily decomposed into histamine after the death of fish. With the extension of the death time of eel, the decomposition of histamine acid will be accelerated under the action of bacteria, and more and more histamine will be accumulated in eel.
