The crayfish's real name is "Crawfish Procambarus" and its scientific name is Procambarus clarkii. It is a kind of fake freshwater prawn. It is not an insect at all. It is related to lobsters. They are classified as "decapoda." Lobsters are lobsters, crayfishes, or crayfishes. The crayfish we eat are pupa (so some in northern China. It is directly referred to as "è²è›„".

Before cooking, merchants generally use crawfish powder to wash crayfish in order to save time and cost. Many people believe that the industrial strong acid in shrimp powder, “oxalic acid,†is the main cause of muscle dissolution. Chen Yusheng told reporters that there is currently very little evidence that eating crayfish results in muscle lysis. Dr. Yun of the Department of Agriculture and Biology of the Department of Agriculture at Purdue University unabashedly pointed out that oxalic acid is widely present in foods, such as spinach. Although oxalic acid itself is corrosive, it can cause symptoms such as vomiting and nausea due to stimulation of the body's digestive system if it is consumed in large amounts in a short period of time. However, patients with muscle lysis do not have similar symptoms. Therefore, oxalic acid is not the cause of muscle lysis. How to eat crayfish before it is healthy?
