Why can't you eat the dead crab?

Autumn wind rises, crab feet itching;

The chrysanthemums are blooming, and the crabs are heard.

In autumn, crabs are an indispensable food on the table. However, although crabs are fragrant, the price is expensive. Some people buy cheaper dead crabs, and some unscrupulous businesses are sold directly as live crabs.

But in fact, some dead crabs cannot be eaten, and eating by mistake may cause poisoning!

Dead crabs, it is best not to eat it!

Fresh freshness such as fish, shrimp, and crabs is fresh enough to be delicious enough. Those fresh and dying fresh fresh in the supermarkets are often discounted, such as "backstroke bass".

Joy back to joke, return to the topic: Dead river crabs cannot be eaten!

why? Crab is omnivorous animals, from dead fish, live fish, to plants, snails, shrimp, worms, eat everything, and eat corrupt food. Because of this, crabs are easy to carry a variety of bacteria and toxins.

When the crab is alive, the gastric (sand sac) of the crab is intact and can work normally, and the bacteria and toxins are also suppressed.

But when it died, everything changed.

The sand sac may be damaged, the toxins are extended to the muscles, and the muscles will quickly soften, paste, and lose the delicate taste of fresh crabs.

Bacteria breed quickly, and protein and free amino acids are decomposed into biomedide. Simply put, excessive bioidemine can poison the human body. Among them, the most toxic is histamine. Moreover, it cannot completely eliminate its toxicity at high temperature.

When intake of excessive amine, it can cause allergic poisoning symptoms such as headache, nausea, dyspnea, palpitations, palpitations, rash, hypertension, vomiting, etc., which can also cause shock and life.

Therefore, in case, don't eat even if you just swallowed crabs.

Someone wants to ask, what about the sea crabs? Sea crabs are different. Because the growth environment is special, it is very easy to die after being salvaged. As long as it is frozen and preserved in time, the dead sea crabs can be eaten, but the taste is greatly reduced, but it should not be stored for too long.

Focus on:

The river crabs are dead, don't eat it!

Sea crabs are dead and can usually eat, but it tastes good.

So the question is -how to judge crabs and lives?

Pick crab, choose "Essence of Qi" foot!

I often see that the crabs are tied up by the rope. At this time, you can touch the crab's eyes with your hands. What you can avoid quickly is alive. And although those who are alive, the soul is "weak", don't buy it!

If you are not tied, choose those climbing quickly and dancing your claws.

If you choose frozen sea crabs, you can take a weight. Holding the heavy, dull and strong in your hand, it is generally okay. You can also touch the back of the crab. It is full of thick, porcelain, and elastic, and relatively fresh.

As for how the male and female divide, see the following figure ~

Some people say that crabs cannot be eaten with persimmons,

is that true?

The saying of "crab and persimmon", the confusion index is absolutely five stars, what is going on?

The real situation is that persimmons contain a certain amount of tannins (also known as "tannic acid"). The mature sweet persimmon tannin content can be lower than 0.1%, and the immature astringent persimmons can be as high as 4%. If you eat a lot of tannins and have a lot of protein in the stomach, tannins will cause protein to form insoluble complexes and make gastric protease lose activity. Coupled with other ingredients such as pectin and dietary fiber in persimmon, mixing may form "stomach persimmons", causing digestive tract obstruction and cause abdominal pain. The legendary persimmons and crabs cannot be eaten together with high tannin's astringent persimmons, because crabs are high -protein foods, and the tannin content in astringent persimmons is high. Eating a large number of abdominal pain may occur.

In fact, it is not insurance to eat astringent persimmons alone, because you do not know what you have in your stomach. If it is a mature sweet persimmon, it doesn't matter if you eat it with crabs.

If you are uncomfortable after eating this, it is likely that you eat too much persimmon or crab, or it may be poorly digestible. (The delicious big crab is not a pot)
