Extended information
Squid ink mainly contains elements such as water, melanin, mucopolysaccharides and potassium, and also contains a small amount of toxins. This toxin has little harmful effect on the human body. Moreover, it will be decomposed and destroyed during high-temperature heating. Therefore, squid ink can be heated and eaten, but it is not recommended to eat it raw.
The mucopolysaccharides rich in squid juice can inhibit the growth and reproduction of cancer cells and have certain anti-cancer effects. ?
