Why can t the river mussels that used to be seen everywhere in the countryside be eaten? Why are wil

Whether the mussels can be eaten or not depends on the water area in which they are produced, and in the past, all river mussels in the water body were edible because there was no pollution. River mussels are very pollutant-tolerant aquatic animals, so if the water is polluted, try not to eat them. In fact, the most critical problem is that the mussel cooking is very skillful, once it is not done well, except for the fishy smell, the meat can not be chewed, and naturally few people eat it.

There are fewer mussels, which is caused by changes in the environment. With the development of society, factories are more common in rural areas, so that many clear streams have become stinky ditches, although river mussels have a certain degree of pollution resistance, but they naturally cannot survive if they are too polluted.

River mussels are very resistant to pollution, there are a lot of pollutants in the body, there will be a lot of parasites in the body, and it is easy to have diarrhea when eaten in the stomach. Because the environment in the countryside is very polluted now, there are factories around, and it is difficult for wild river mussels to survive.

Because the mussel has a lot of parasites in its body, and it grows up in the mud; Because the requirements for water quality are very high, and there are many places where rivers are dammed.

Because the meat of the mussel is tight and hard, and the fishy smell is particularly strong, there are fewer people who eat it.

In fact, the nutritional value of river mussels is very high, containing protein, fat, sugar, calcium, phosphorus, iron, vitamins A, B1, B2. Each 100 grams of edible part of the mussel contains 248 mg of protein, 248 mg of calcium, 305 mg of iron, 305 mg of zinc, 243 mcg of vitamin A, microg of selenium, and microg of carotene.

It also contains more riboflavin and other nutrients, and the total energy can reach megajoules kilograms. River mussel meat has a good health care effect on the human body, and has the functions of nourishing yin and flattening the liver, brightening the eyes and preventing eye diseases.

The water quality of the current river is not good, so the mussels rarely appear. The mussels that appear now are also avoided as much as possible.

The riverside is not to be eaten, because the riverside in the rural ditch is very dirty, so it cannot be eaten, and because the water resources have been destroyed, there are very few now.

River mussels used to be found in small river ditches in the countryside, and the taste was also delicious, and it was edible.

Be sure to cook it when you eat it, because this kind of thing can sometimes have parasites.

Of course, since I grew up by the sea, I recommend eating a paella. The seafood is fresher than the river fresh, if you can, go and eat the razor clams and tofu soup.

Of course, it can be eaten, but these river mussels have very high requirements for water quality, and now the water quality is poor, so there are fewer of them.

I think you can eat it as long as it is clean. The reason why there is less now is because of environmental pollution problems.

I can eat it because the current environment is very different from the previous environment.

1. Between the thin skirt of the mussel and the thick mussel flesh, there are two half-wrapped parts of the mussel, which are crescent-shaped, soft, and have a gill-like texture inside, and they should be removed.

Next to the gills, it is in the shape of a tube, with black mud and sand inside, one end is connected to the mussel body, which is to be pinched, and the other end is glued to the foot of the columnar axe and torn off. Gently squeeze the mussel body to the hole where the intestines are broken, squeeze out the black sediment inside, drain it, and finally wash it.

2 First of all, soak the mussels in salt water for half an hour to about an hour, if you are not in a hurry to eat, then it is recommended to soak for 2-3 days. The whole process of soaking in salt water can allow the mussels to spit out the excess impurities first, and the river mussels that have not been soaked in salt water will bring a certain degree of difficulty to the later treatment.

The black internal organs inside the mussels must be cleaned, otherwise eating them will lead to diarrhea and other conditions. When the outer membrane is untied, you will see pale yellow or orange-yellow gills, and the gills will be removed, and there is also a black mud intestine behind the mussel.

If you want to wash off this mucus thoroughly, you can add a little water to alum, put the mussels into it and soak it for 2-5 minutes, and then wash it with water. When the mucus is cleaned, it will make it easier for the mussels to absorb the flavor during the stir-frying process, and the taste will become better. Note:

When alum is diluted in water, it must be in moderation, otherwise it will destroy the original taste of the mussel.

One of the most important steps is to pat the part of the mussel that resembles the mouth of an axe with a knife, the purpose of pat loose is to make the cooked mussel taste more fluffy and delicious. If you don't have this step, then there's a good chance you'll not be able to bite it.

3 The treatment of the river mussel is very important, Chang did not call, but how to choose the river mussel is also very important, when choosing the river mussel, as long as you gently break it with your hand, if there is a smell of Naikai, then you can be sure that it is a dead river mussel.
