The shrimp yellow on the head of crayfish is not equal to crab yellow. Shrimp yellow is composed of brain, heart, stomach and digestive gland, so there is no way to distinguish them completely when eating. It is possible to eat the dirty things and parasites in the digestive tract. At the same time, the lungs on both sides of the lobster will be connected together, so some dirty things filtered by the lungs may also be eaten. For the mother shrimp, there are ovaries in the shrimp yellow. So generally speaking, the shrimp yellow on the head of crayfish can't be eaten.

Shrimp tail is actually a high-protein and low-fat food, which is the same as milk, eggs and meat. It is a high-quality protein and can be used as a supplement to the protein in food. But be careful when eating, and be sure to remove the shrimp line, that is, its intestines. In addition, during the processing of shrimp, try to heat it thoroughly, and don't eat it half-baked to avoid the problem of parasite residue.

How to clean crayfish correctly

1, add some edible salt and white vinegar to the clear water, and put the crayfish in it for soaking. When the crayfish is soaked, it will continuously spit out water, and at the same time, it will also spit out sediment and dirt.

2. Wash the crayfish after the crayfish can't spit out any sand. When washing, it is best to find a small brush or toothbrush that is not used, and brush the shell of crayfish well, and it is best to brush the abdomen several times, because there is a lot of sediment in the abdomen of crayfish. When cleaning, remember to hold down the pliers of crayfish to prevent them from scratching us.

3. After cleaning the crayfish, use scissors to cut a knife obliquely at two-thirds of the head of the crayfish to remove the internal organs of the crayfish. After removing the internal organs of the crayfish, grab the tail of the crayfish, twist it slightly from left to right, pull it out along the curvature of the shrimp, and slowly pull out the shrimp line.
