What are the crab offal that cannot be eaten? How to deal with crab offal

September and October are good times to eat crabs, especially hairy crabs. Crab meat, crab roe, crab paste, and crab claws are all very delicious, but you should be careful when eating them, as some of the crab's internal organs cannot be eaten. So which ones are inedible?

What crab viscera can't be eaten?

There are four parts of hairy crabs that cannot be eaten. The first is the gills, the second is the stomach, the third is the heart, and the fourth is the intestines.

The crab's gills are the part that comes into contact with the outside world the most and they smell a little fishy. The most important point is that they are used to filter impurities in the water, so we cannot eat their gills.

The crab intestines and crab stomachs are also not edible. Because the main food of crabs is rotten fish and earthworms, there are a lot of dirt in the stomach of hairy crabs, and there are also a lot of excrement in the intestines of hairy crabs, so these two are also not edible.

The last one is crab heart. Because crab is a kind of cold food, and the crab heart is the coldest part, so it must not be eaten.

How to deal with crab viscera

Crab intestine: located in the umbilicus of the lower abdomen

Turn the crab over and open the navel on the abdomen. You can see a thin black tube. This is the crab intestine and it should be taken out.

Crab heart: located in the center of the crab body

The crab heart is not easy to find. We pierce the black membrane in the center of the crab body and take out a hexagonal thin piece inside. This is the crab heart.

The heart of the crab is very cold and therefore should not be eaten. If you are eating a small crab, the heart of the crab will be more difficult to find, so be careful when eating it.

Crab gills: located on the left and right sides of the crab body

The crab gills on both sides of the crab body are shaped like eyebrows and sponges. This is the respiratory system of the hairy crab and is not edible and needs to be removed.

Crab stomach: located on top of the crab shell

After opening the crab shell, you should immediately remove the crab stomach and discard it. The crab stomach is a triangular sac that is wrapped in crab roe and can be eaten by mistake. There is a lot of sand in the crab stomach, and if eaten by mistake, it will have a bitter taste.

What should you pay attention to when eating crabs

Avoid eating dead crabs: after a live crab dies, the bacteria in the crab's body will gradually spread into the crab meat.

Avoid eating raw crabs: The flukes that live in the lungs of live crabs can cause fever, coughing and coughing up blood. If they invade the brain, they can cause paralysis.

Avoid eating overnight crabs: If crabs are left overnight, the histidine in the crab's body can be decomposed into histamine under the action of certain microorganisms. This is a toxin that cannot be destroyed by heating, leading to histamine poisoning.

Avoid eating too much: Because crabs are cold in nature and the cholesterol in crab roe is very high, the average person should not eat more than 1 jin of crab roe at a time, and should not eat crabs more than 3 times a week.
