I wonder if you have seen cuttlefish dumplings? Black dumplings, in fact, are filled with cuttlefish juice, which can often be seen in Shandong restaurants. I've eaten it, but I don't feel any special taste. It's delicious. The black color of cuttlefish juice comes from a kind of natural melanin, which is actually the same principle as human moles. It is a phenomenon that tyrosine is gradually transformed into black substance under the action of a series of biological enzymes, which is ubiquitous in animals and plants.
For example, shrimp hair will turn black after a period of time, apples will turn brown after being cut, and potatoes will also change color after being shredded, etc., all of which are the same thing, but different species have slightly different biological enzymes. This melanin is linked with an egg white, which is an important component of cuttlefish juice.
According to the consequences of scientific research, cuttlefish juice is actually quite nutritious, and this melanin has another inevitable health care function, but it needs to be purified. There are many other uses of cuttlefish juice. In Japan, there is ice cream made of cuttlefish juice, which is dark, but I can't accept it anyway. It seems that KFC had a cuttlefish meal before, and the result was that professional counterfeiters (that is, professional claimants) placed people everywhere, bought 10 million, and then sued the court, saying that KFC used non-edible substances and had to pay 10 times.
Consequences Later, the Ministry of Health wrote back that cuttlefish juice has traditional eating habits and can be used in food, and counterfeiters were beaten. Both cuttlefish and cuttlefish have ink, which is actually edible, so don't worry. If you don't want to eat, don't eat, it's nothing.
