Because crayfish are rich in protein and magnesium, zinc, iodine, selenium and other trace elements as a gourmet dish, it has also become a regular customer at the summer table in Hubei.
In addition, crayfish contain astaxanthin, which is a strong antioxidant, and crayfish can also be medicated, which can dissolve phlegm and cough, and promote wound muscle healing after surgery.
With such a high nutritional value and delicious taste, the taste is excellent, especially under the commercial momentum of "xx steamed shrimp" and "xx oil braised prawns", almost all people can't help but want to shout: "Crayfish, this summer I want to date you!" ”

But how can you be unprepared before a date? Well, "dating" crayfish we need to pay attention to these rumors!
1. 【Crayfish food】Contain hormones and birth control pills?
The heavy use of hormones will increase the frequency of shelling of crayfish and slow down the growth rate. Moreover, the growth cycle of crayfish is very short, and it can be listed in about 3 months, and it does not need to be spawned.
The use of birth control pills to speed up its growth rate is also a rumor. Because shrimp are lower invertebrates, higher vertebrate contraceptives are ineffective against them. In addition, the sexual maturity period of shrimp is 8 to 10 months, that is to say, the shrimp is still very early from the breeding period when it is on the market, and there is no reproductive ability at all, and raising shrimp with contraceptives will increase the cost in vain.
2. [The growth environment of crayfish] is it in the sewage ditch and the heavy metals in the body exceed the standard?
Web-borne crayfish mostly grow in "stinky ditches" and are prone to disease-causing bacteria. Professor Pan Liande of the School of Fisheries and Life Sciences of Shanghai Ocean University said that crayfish are not easy to survive in the harsh living environment and grow slowly. They prefer clean water sources, and if the water quality is poor, the crayfish not only have difficulty reproducing, but also have poor shelling and slower growth.
CCTV "Focus Interview", Tang Jianqing, director of the breeding room of the Jiangsu Freshwater fisheries research institute, introduced that in a Y-shaped maze designed, fresh fish pieces were placed on one side and rotten fish pieces on the other side, and after hundreds of observations, more than 99% of the crayfish went to fresh fish blocks.
Farmers have also found that while crayfish can survive in clean and dirty places, it prefers clean places. It is unscientific to judge that crayfish like to live in a dirty environment by "fishing in the gutter and not in the clear water". The crayfish grown in the clear water are very vigorous and difficult to catch without tools, while the life vitality of crayfish in polluted environments is very poor and difficult to reproduce.
Moreover, crayfish are very sensitive to heavy metals, and in water bodies with excessive heavy metals, crayfish cannot successfully dehull and survive. Crayfish feed on aquatic weeds and other foods, and have low accumulation of heavy metals.
3, [the use of crayfish] crayfish used to treat sewage on the Chinese table?
Rumor has it that crayfish originally came in from Japan for cleaning up dirt. According to the People's Daily in 2012, Katsuhiro Sasata, an associate professor of bio-environmental engineering at the Department of Biological Resources Sciences at Nihon University, said that he had never heard of using crayfish to purify sewage, because crayfish need to dig holes in soiled paddy fields and ditches to build nests, and the equipment for urban sewage is cement and steel bars, which is not suitable for crayfish to survive.
Crayfish have been eaten in some countries for more than 200 years. China exports every year, and 90% of the crayfish in the European market come from China.

Before eating, in order to ensure food safety, you must also pay attention to the "dating" link.
1. How to "meet" with fresh and hygienic crayfish when going out?
In a restaurant, is it about to start eating crayfish with bright red color and appetite? No, let's first judge whether the crayfish in front of you is fresh and hygienic through the "golden eye of fire".
First, you can judge by looking at whether the crayfish's gills are clean. Shrimp usually raised in shallow waters will have blackened gills because of the more impurities in the water, while only shrimp farmed in deep water lakes will have clean gills. Secondly, if the tail of the crayfish is curled up, it means that it is alive before entering the pot. If the tail is straight, it is dead before it is put into the pot. In addition, it can also be judged by whether there is a fishy odor and whether the meat is soft and inelastic.
Since 2009, there have been continuous media reports that the bright crayfish sold in restaurants are most likely soaked in "washed shrimp powder". After soaking in it, the original dark crayfish suddenly became bright. A reporter conducted field investigation and evidence, confirming that the shrimp washing powder was a chemical with extremely high purity: oxalic acid. Oxalic acid is the "melamine" of adults, or even more so. Professor Hao Fengtong, chief physician of the Department of Occupational Diseases and Poisoning Medicine of Beijing Chaoyang Hospital, introduced that the biggest harm of oxalic acid to people is urinary system stones. Oxalic acid easily enters the body through the respiratory tract, digestive tract and mucous membranes of the skin. Adults who mistakenly take 2 to 5 grams may lead to death.
The oxalic acid in washed shrimp powder is treated with water, which greatly reduces the possibility of acid burns in the human digestive tract; but it will make people consume more unknowingly, and the results are self-evident.
Because washing shrimp powder has a certain corrosive and irritating effect, shrimp after processing with it, shrimp tongs are easy to fall off after cooking, and attention is also paid to when eating.
2. How to have an "unforgettable date" with crayfish at home?
When buying crayfish, first look at whether the back is red and clean, and then open it to see its abdomen fluff and the hairs on its claws, here if it is white and tidy, it is basically clean and watery. In addition, crayfish are aquatic animals that eat the carcasses of humus animals, and bacteria and toxins will only accumulate in the body more and more, so you should buy newly grown crayfish. When buying, you should look at the skin color: the old lobster is either red and black or red with iron blue, and the green lobster has a natural and healthy luster. Touch the shrimp shell with your hand, the iron is hard is old, as elastic as the nail is just grown shell, try to buy soft shell crayfish.
For crayfish cooked at home, it is recommended to feed them with water for about 24-36 hours before cooking and processing, so that the shrimp body spits out metabolites. During processing, it is best to remove the head and shrimp line while cutting off the two gills and lobster claws that are easy to hide dirt and grime, and brushing the shrimp shell with a brush.
The cooking of the crayfish must be thoroughly cooked at high temperatures, so as to ensure that the bacteria and parasites in the lobster are killed. It is recommended to choose carefully the "secret seasoning" sold, try to use healthy cooking oil, and try to choose a cooking method that better retains the nutrition of crayfish, such as steaming and boiling.
In addition to removing the shrimp head and shell, eating crayfish should also remove the shrimp line, because the shrimp line is filled with feces, and the cooking temperature and time may not meet the requirements. Specifically, after removing the head of the crayfish, peel off the shell of the shrimp and remove a thin line from the head to the tail in the middle of the shrimp meat, which is either black or white.
3. Choose a good dining environment
As the temperature rises, meeting relatives and friends at food stalls on summer nights is the choice of many people. However, summer is also a high-risk period of "disease from the mouth", and it is very important to choose a clean and hygienic dining environment. Some people like the authentic taste and casual atmosphere of "fly restaurant", but "fly restaurant" also has problems such as poor sanitary conditions and irregular raw material processing process, which makes germs have an opportunity.
4, eat reasonably, do not overdose
Due to the high protein content of crayfish, shrimp should also be moderate when eating shrimp, ordinary normal people do not eat too much at one time, to prevent indigestion, causing a heavier load on the gastrointestinal tract. Everyone often brags about "eating several large portions at a time" is actually a very bad eating habit, and sometimes it can trigger the possibility of pancreatitis attacks.
Although the oil braised prawns taste good, but the use of cooking oil is large, with the more you eat, the intake of oil also increases, and, like to eat spicy people, salt intake has also increased, these are actually very unhealthy.
In particular, be wary of the so-called secret recipes, how do you know which of those secret materials are artificially added. You know!
Therefore, reasonable eating without overeating is a principle that foodies must abide by.
5, special groups should be cautious
People with metabolic diseases such as allergies and hyperuric acid should be careful. As one of the common allergens, crayfish should be eaten with caution in some people with allergies. Crayfish are also rich in purines, and gout patients should not eat them, let alone eat them at the same time as beer.
