In fact, I don't know the growing environment and water quality of crayfish. All we see in the market are canned crayfish, so how to choose healthy and high-quality lobster has become a difficult problem, and many people are still not sure at this time. Lobsters are omnivores. It likes to eat dirt, dead fish, shrimp, plankton and so on, so it contains a lot of bacteria and parasites. The purchased crayfish should be soaked in water containing appropriate amount of salt for several hours, during which the water should be changed several times to make the crayfish spit out dirt.
Relatively speaking, the price of first-class shrimp is also the highest. Second-class shrimp and third-class shrimp are not as good as first-class shrimp in size, physique and meat quality. So its price is naturally not as good as the best shrimp. If we ordinary people go to the market to buy shrimp, we only choose according to the size of the head, and other estimates are not obvious. However, in supermarkets, they also install them in different categories and indicate the prices. Generally speaking, we only need to buy according to their classification. But generally speaking, most of us only like to eat the tail of crayfish, which is called shrimp balls. As long as the meat is full and tender, it is almost like shrimp.
Lobster is rich in nutrition and is also common in people's daily life. It is worth noting that the best lobster is of the best quality. Similarly, its price will be slightly higher than that of second-and third-class lobsters. This classification can make people clearly understand the quality differences of lobsters. The higher the grade of lobster, the better the quality. So generally speaking, when buying lobsters, choose to buy first-class lobsters. Quality is the best. Then, the second level will be slightly worse than the second and first levels, and the third level will be worse than the second and first levels. Mainly according to different qualities.
