While the crab fat cream is beautiful, it's time to find out.
are all dead crabs, why is some delicious, some poison?
: not dead to the place, to die in the steamer.
amino acids are one of the characteristics of aquatic products, but also one of the reasons for fresh taste, from lobster to purple vegetables. Like crab sweetness and freshness comes from glycine, alanine and so on. Among these amino acids, there is a kind of histamine, delicious and nutritious, for a live jumping waiting to get off the pot of crab, is definitely the part of the plus point.
However, our dragon king's crabs, dancing their teeth and claws, are not so powerful in the food chain, they often eat corruption, they also have to reach a compromise with the parasitic flora: when the crabs are alive, they hold each other back, and once they become dead crabs, these flora will expand rapidly. Some of these bacteria just break down histamines into histamines, which can cause poisoning. Histamine accumulation can only be avoided if you get out of the pot alive and kill the bacteria at high temperatures.
bacteria break down histamines and accumulate histamines quickly, even dead crabs are at risk of poisoning. Especially in the transport process, some crabs have been dying very weak, in fact, this time the body has begun to accumulate histamine. So, if you buy such a crab do not want to throw, contact the seller, let him give you a refund!
died outside the steamer, and there is no exception. When a vibrant crab falls to your eyes and dies, the strong crab immediately doesn't get out of the pot, 18 minutes later, or a delicious meal.
delicious crabs, why can't you buy more frozen and eat them slowly?
answer: not only delicious frozen, but also the risk of poisoning.
are frozen and sold, basically sea crabs. Although the crab as a river crab also has frozen sales, but at present is limited to cooked. The reason why river crabs are not suitable for frozen sale is partly due to the increased risk of poisoning caused by the accumulation of histamines mentioned earlier. Another reason is that the current technology to freeze river crabs, will greatly reduce the delicious river crabs.
sea crabs are much less at risk for histamines because seawater has its own sterilization properties. Of course, this does not mean that eating frozen seafood is certainly safe, especially some green red meat sea fish histamine content is high, or pay attention to pick fresh.
why is it called a crab? How many legs are the crabs on?
: Because of the bamboo gate that catches crabs;
before the crabs have not been farmed, to autumn, the most "popular" is to go to Yangcheng Lake to catch. In the water system connected waterway set up bamboo gate, at night with the light to attract crabs to climb the bamboo gate, easy to catch, so called the gate crab. And this "big" word, naturally is to express the love of eating crabs and the joy of eating crabs.
from a tax classification point of view, we eat the river crabs are basically velvet crabs of the Gen. Because the growing waters are good, the crabs take up a lot of time and land, belonging to the Chinese velvet crabs in the better food.
how many legs does the crab have? In terms of taxonomy, it's 10 articles, but the text also says that crabs are six kneeling and two.
in taxonomy, crabs are full of eyes, and the thyme, legs, and the last two strokes of water are counted. And the text said six kneeling, some people speculated that he saw the shuttle crab, the back two used to draw water excluded from the legs. We now see that the king crab has two fewer legs, but in fact the last two have degenerated. To tell a joke, people may not dare to eat long...
