Why is the meat of some crabs bitter to eat

Because crabs are in the process of breeding, because the water body is dirty, the bait is perishable, and it is a high-density culture, crabs are susceptible to bacteria, viruses, fungi and parasites infection, and various drugs must be used to control the growth cycle and mortality rate of crabs in the growth process. However, before coming out of the water, some crabs are not completely excreted, and they will have a bitter taste, so you can soak them for a period of time before boiling them to let them excrete cleanly.

No matter what part of the crab has its unique taste, the delicious crab meat, and the crab roe are even more gluttonous, but some friends find that the crab they buy back tastes bitter. So what is the reason why crabs are bitter?

1. The water quality is too poor: the water quality is poor, and the crabs bred in this way are seriously polluted, and the body will naturally be enriched with a lot of harmful substances, which makes the crab meat and crab roe have a bitter taste.

2. Insufficient net cultivation time: the raising time is too short, and the crabs are not cleaned, and they will naturally have a bitter taste when eating.

3. Drug reasons: crabs are greatly affected by water quality, and other drugs are needed to control their growth cycle and mortality.

The above is the introduction of what is the reason why crabs are bitter, I hope it will help you.

The bitter taste of blue crab meat may be caused by not completely excreting the excrement in the body before coming out of the water, or it may be caused by dirty water, high-density farming and long-term consumption of perishable bait. If you don't want to eat bitter blue crab meat, you can soak the blue crab in salt water for a period of time and wait for it to drain to remove the bitter taste, so that the blue crab will not taste bitter.

At present, the domestic blue crab is very expensive, so that the breeding of blue crab can make huge profits, many farmers will change the original paddy field into the blue crab breeding base, the water circulation of the paddy field is very slow, the water quality is also very poor, so that the breeding of the blue crab has been seriously polluted, the body will naturally be enriched with a lot of harmful substances, so that the meat and crab roe of the blue crab are bitter.

Therefore, the blue crab needs to be put in clean water for at least two days of excretion after purchasing, during this time, the blue crab does not eat, the stains in the body will all be discharged, if the time is too short, the blue crab is not clean, and it will naturally have a bitter taste when eating.

Try to raise a few days more, buy back the blue crab I don't know if it is a regular breeding base breeding, the blue crab also needs to be recuperated with clean water for a period of time after the purchase, it is best to be active running water, which can remove the food residue in the blue crab to the greatest extent, and wait for the blue crab to let the whole type of harmful substances in the body be discharged from the ridge before eating, there will be no bitter taste.

The reasons are as follows:1. The crab is not yet mature.

The bitter crab roe is different from the golden crab roe we commonly see, the crab roe is lighter in color, thinner, and does not form lumps, this is because the crab is still too tender, the time has not yet come, and the crab meat at this time is not thick.

Suggestion: Continue to raise hairy crabs for a period of time before eating.

2. Insufficient preparation for crab cooking.

Insufficient preparation for crab cooking can also lead to bitter crab roe. Hairy crabs should be prepared well before cooking. In addition to the hairy crabs in Yangcheng Lake, crabs must be kept in clean water for two days before they are bought and put into the pot.

Two days later, the crab was basically "cleaned". When the crab is cleaned, the dirt in the stomach is drained, and the crab roe will naturally not be bitter.

3. The crab is already sick.

Sick crabs, the crab roe is bitter, and the ointment will not be firm. Such crabs are easy to die, and some are very large but not enough in size. There are some gray-brown spots on the shell of the sick hairy crab, or the pattern, which is the common saying "coccidiosis", a common disease of crabs, and it should be noted when buying.

The reasons for the bitterness of hairy crabs: the crabs are too tender, the environment is polluted, and the crabs are not fresh.

1. The crab is too tender.

The bitterness of the crab may be due to the fact that the crab itself is not yet ripe, and then the crab roe is not lumpy, so there will be a bitter feeling when eating, and it is generally recommended to buy mature crabs. Tachibana is gone.

2. Environmental pollution.

The environment in which the crab lives will also affect the quality of the crab to a great extent, and the water quality is poor and the heavy metal exceeds the standard, and the crab will be seriously polluted, resulting in its bitter taste and causing harm to human health.

3. Crabs are not fresh.

Stale crabs, such as sick or dead crabs, may have rotted or deteriorated inside, and then use them for cooking and eating, not only destroying the umami taste of crabs, but also having some bitter taste.

Precautions for eating crabs.

1. Do not overeat.

As raw crabs contain more bacteria, parasites and sludge, they need to be cleaned and cooked until they are cooked thoroughly before eating.

2. Do not eat long-term cooked crabs.

Cooked crabs stored are very susceptible to bacterial invasion and contamination, so crabs should be eaten freshly and not stored. In case you can't finish eating, the rest must be kept in a clean, cool and ventilated place (preferably in the refrigerator), and must be returned to the pot and steamed thoroughly when eating.

There are three reasons why the yellow of the crab tastes bitter:

1. Crabs are not yet ripe: the color of the crab roe of immature crabs is relatively light, and there is no peikai coagulation, which tastes bitter;

2. Insufficient preparation for crab cooking: there are dirty things in the crab roe with this residue will cause the crab roe to have a bitter taste, and the crab needs to be raised in clean water for two days before cooking, so that the crab can drain the unclean things in the stomach;

3. The crab is already sick: The crab roe is bitter and not firm when it is sick. Sick crabs have gray-brown spots or patterns on their shells, so be careful to identify them when you buy them.
