Every year in the golden season of May and June, the crayfish smells in the streets of various cities. Every time at this time, Xiao Mao's illness can not help but want to call on three or five friends, sit down in the food stalls, to a few kilograms of lobster, a few bottles of beer. However, in recent years, there have been more and more rumors about crayfish being unable to eat. For this reason, Xiao Mao Xiaoji specifically collected information on these rumors and all parties' interpretations of these rumors, in order to just watch! Myth #1: Crawfish is not a shrimp. It is an insect. Foreigners do not eat it. Crayfish is a kind of freshwater crayfish belonging to the crustacean subfamily of the Arthropod Crustacea. It also has its own scientific name, called crawfish. The crayfish's hometown is neither in China nor Japan, but is from distant North America. Its main habitat is the Gulf Coast, especially the area near the Mississippi Estuary. Fast growth, strong adaptability, and ability to survive in both clean and polluted environments are the characteristics of this type of shrimp. Crayfish can eat a lot of things, appetite is very good, belonging to omnivorous animals, aquatic plants, algae, aquatic insects, animal carcasses, etc. can eat. The United Nations Food and Agriculture Organization of the United Nations had statistics that the annual trade of crawfish in the world was as high as 300,000 tons. In the United States, the home of crayfish, the crayfish began to eat crayfish more than 200 years ago, and the quantity is large. There are also many markets that sell crayfish exclusively. European countries also eat only Japanese people. I really do not like to eat, because I think the crawfish meat quality is more firewood. Rumor 2: During World War II, Japanese biochemical forces stationed in China genetically modified the crawfish (predecessor of the crayfish) to the Japanese garrison for a living without food. This is the most well-known and most leaking rumors. The crayfish crayfish is the scientific name of crayfish, not a predecessor. Japan introduced crawfish from the United States about 1927, mainly as a feed for bullfrogs. In addition, crayfish was indeed brought to China by Japan, and about 1929, it was also used as feed and food. The earliest landing site was near Nanjing. At this time, the Anti-Japanese War has not yet broken out. Nanjing and the surrounding areas are not in the daily occupied area. There is no body disposal. (Shell network thin camel) In addition, during the War of Resistance Against Japan, the concept of genes has not yet been formed, let alone genetic modification. Myth #3: Shrimp powder contains industrial acid "oxalic acid" which is the main cause of "muscle lysis". Oxalic acid is not the culprit leading to muscle lysis. Oxalic acid (oxalic acid) is widely found in food, and there are many in spinach. If a large amount of oxalic acid is eaten in a short period of time, oxalic acid itself is corrosive and can cause irritation to the human digestive system before it enters the bloodstream, rapidly leading to vomiting and nausea. However, patients with muscle dissolution do not have this symptom. (Husk shell cloud inadvertently) Myth 4: Crayfish exceeded the standard for heavy metals. Crayfish have a strong resilience to toxic water bodies. Lead, mercury, manganese, chromium, arsenic and other heavy metals can accumulate in the body to several hundred times normal. Crayfish are indeed very resistant to environmental pollution. However, it has a good discharge attenuating mechanism, and its internal pollutant content is not necessarily exceeded. Crayfish can transfer heavy metals to the shell and then transfer the toxin out of the body through continuous molting, which is one of the reasons it can tolerate heavy metal contamination. Current research shows that although crayfish have a certain ability to enrich heavy metals, they are mostly concentrated in shrimps, viscera and shrimp hulls that we do not like. For people who eat shrimp meat, it is likely to cause heavy metal poisoning. Less sexual. Perhaps it is because of illnesses caused by eating crayfish, but it is a case after all. In the era of rampant food safety, apart from the problem, people are not blamed on the problem. It is simply unfair to blame the crayfish itself. How to eat crayfish correctly? It should be noted that crayfish and crabs are intermediate hosts of Pneumocystis and cannot be killed by roasted, fried or salted, drunk, etc. processing methods. Therefore, whether it is crayfish or other fresh seafood, try not to eat raw. In order to ensure that the lung flukes are killed, it is recommended to keep the cooking temperature above 100°C for no less than 10 minutes. In addition, the shrimp head of crayfish is susceptible to bacteria and parasites, so do not eat it.
