Can crayfish head be eaten?
Crayfish is small, but has five internal organs The shrimp body you eat is actually just its tail. The shrimp head is an extremely complex part, which contains many important internal organs, most of which cannot be eaten. The shrimp head is actually only the shrimp yellow.
The yellow part is the midgut gland of the crayfish. A simple understanding is the part responsible for digestion. It also stores some lipids. Anyone who has eaten it will understand that good food is necessary.
Are the shrimp heads really dirty?
We all know that crayfish have strong environmental adaptability and can survive in sewage , The heavy metals in the sewage will be concentrated in the gills and internal organs of the head, but this does not mean that the shrimp heads you eat are very dirty!
Here is a set of experimental data, which are in different parts of crayfish. The heavy metal content is roughly distributed as follows:
Lead: shrimp intestines> shrimp shell> shrimp head> shrimp yellow> shrimp tail meat
Cadmium: shrimp yellow> shrimp head> shrimp intestine> shrimp shell ＞Shrimp Tail Meat
Chromium: Shrimp Intestines＞Shrimp Shells＞Shrimp Heads＞Shrimp Yellow＞Shrimp Tails
Total Mercury: Shrimp Tails＞Shrimp Intestines＞Shrimp Shells ＞Shrimp head＞Shrimp yellow
The experimenter said that there are two ways of heavy metal pollution in aquatic products. One is exogenous pollution, which refers to the environment in which aquatic products live ; One is endogenous pollution, which is its own concentration and enrichment of heavy metals. As an industry, crayfish has been standardized and cultivated. Artificially cultivated lobsters have a controllable environment and controllable heavy metal concentration. The concentration of heavy metals is greatly reduced. The wild ones will be at ease.
So be sure to buy crayfish from artificial legal farms. Generally, crayfish raised in clean water have relatively low heavy metal content. Don’t buy crayfish from unknown sources just for the sake of cheap. Potential harm.
Aside from the dose to talk about toxicity, it is a hooliganism. As long as you are not eating every day, all meals, or all year round, for healthy adults, you don’t need to panic. But children, Pregnant women and those who are infirm, it’s better to eat less shrimp heads. In addition, those who have high health requirements are safer to eat shrimp meat!
First put the crayfish in clean water Then add some flour and stir well. Soak the crayfish in water for a period of time. The flour is absorbent and can absorb all the dirt away. After soaking for a period of time, rinse it again several times so that the surface of the crayfish is very clean. .
Next, process the shrimp head and shrimp thread, and prepare one scissors,Then cut off the shrimp head, cut off half of the shrimp head, leaving the yellow part. Then pull out the two shrimp threads from the middle part of the tail, and finally rinse them again, so that the crayfish are cleaned up and you can eat them with confidence.
