Clams are seafood shellfish, but are the white thin lines in clams parasites?

Clams are marine shellfish. Mollusca. It has two long and narrow shells, with blue eggs on the outside and white flesh on the inside, which are distributed in the coastal areas of our country and live in sandy coastal waters.

The food of razor clams is marine microorganisms and marine algae. It can also be artificially cultivated, and the meat is delicious. It is commonly known in Dalian"Small seafood"There are other varieties in other regions, and it is said that razor clams have the functions of replenishing deficiency, diluting water, and detoxifying carbuncle for external use.

Contains protein, fat, calcium, phosphorus, iron, iodine and other ingredients. Because of its food chain, razor clams can be eaten except for their shells. For this problem, the author went to the seafood market to buy two catties of razor clams, and the current price in Dalian was 20 yuan a catty.

If you want to wash it thoroughly, remove the black spots on the clams on the **, which are the digestive parts of the clams, and some foods are not digested. When you go to the market to buy it, be sure to buy it with seawater. Such razor clams will be cleaner when the sand is spit out.

Don't know if this answer satisfies you? The following is an introduction to the recipe of razor clams for everyone to use in the future. After careful observation with a magnifying glass, you will find that these black things are a small amount of substances in the clam's digestive system, mainly plankton and small algae, not the sand in the sea, the razor does not eat the sand in the sea, but it also has a small amount of sediment in its digestive system, which is the sediment that clams enter when they eat sea baths and plankton, and these sediments can help clams digest food.

This is not the feces of razor clams, which are digested and excreted from the body by the lower part of the fine cavity (the deeper, finer, visible side of the fleshy skirt) and are not preserved in cysts in the digestive system. Before buying razor clams to eat, this black substance should be torn open with your fingernails. Rinse with water, grab a handful of razor clams and rub them together with your hands before rinsing and cooking.

No problem, the black part of the razor clams will affect its seafood flavor and give it a strange taste.

However, if you cook directly without removing the black part, it will not be a big problem after high temperature, but the taste will be much worse. Thank you. As for others, soaking in salt water clears the black belly – no, allows the clams to expel the remnants of digestive juices, but not the food they have eaten.

It's not a parasite, it's an organ of the razor digestive system, called the crystal rod, which is edible, but it is not available in every razor clam, because when the razor is hungry, the crystal rod will automatically dissolve and be used to satisfy hunger.

It is not a parasite, it is an organ in the digestive system, and it is also edible, which can replenish collagen and calcium content.

This is not a parasite, but a digestive organ. The razor clams are digested through this thin white thread.

ClamsThe one inside is not transparentParasites, but the crystal rod of razor clams.

Clams have a transparent nematode-like thing in their bodies, which is actually the clam's digestive system.

One of the organs, called "crystal rod", is mainly composed of proteins, and is also rich in enzymes, which are edible. When the razor clams are eating, the crystal rod acts as a blender to drive the stomach and intestines.

peristalsis, which promotes food digestion; When razor clams are hungry, the crystal rod will automatically dissolve and be used to satisfy hunger.

Therefore, freshly caught razor clams usually have crystal rods, but it does not mean that razor clams without crystal rods are not fresh. Because the activity of the enzyme is different, at the same time, some clams may have finished digesting the crystal rod, and some have not.

What is the black part of the razor clams

Normal razor clams are white, and there is a black part of the body that is the intestinal gland of razor clams, mainly the intestines and some organs, which contain the undigested food after the clams eat, the sediment and digested metabolites when eating, so try to remove them before cooking.

How to clean razor clams

1. Rinse the fresh razor clams directly with water, and it is best to change the water several times, so that all the dirt on the shell of the razor clams can be cleaned.

2. Clean the shell of the razor clams and then take an appropriate amount of edible salt.

Put it in a basin, add water to make salt water, and then put the razor clams in it to soak, change the water once every two hours, then the environment in the water is similar to the usual living environment of the razor clams, it will continue to breathe, and will spit out the sediment in the shell into the water.

3. Soak the razor clams in salt water for three to four hours and then add an appropriate amount of cooking oil in the water, at this time, the oil will form a diaphragm on the surface of the water, which will reduce the oxygen in the water, and the razor clams will feel difficult to breathe.

Breathing faster will make the sediment in your stomach spit out faster.

4. After adding cooking oil to the water for two hours, take out the razor clams in time, and then use a water filter basket to pack it up, and then put the water filter basket in a basin, put it under running water and rinse it with running water, so as to prevent the mud and sand spit out by the razor clams from being sucked back by it again, rinse for a while, and you will find that the razor clams have become particularly clean.

Most of the seafood will have parasites, and the sea clam is no exception, the parasite on the body of the sea clam is generally a creature called "clam intestinal fluke", which is yellow-white, milky white, and about 2 cm long; Parasitic clams are emaciated and unable to reproduce, and if more than one live cram crawls out if it is squeezed on its abdomen, it should be discarded and not eaten again if it is found to be a fluke eaten before cooking.

Some people find a thin white line like a worm in the clams, in fact, this is not a bug, each clam has a transparent nematode-like thing in its body, it is an organ in the clam's digestive system, called "crystal rod", which is edible; However, not every clams have a crystal rod, because when a clams are hungry, the crystal rod will automatically dissolve and be used to satisfy their hunger.

Generally, there will be no crystal rod in the body of the sea clam that has been placed for a long time, and the sea clam will cause the crystal rod to dissolve in the order of the dissolution time due to the speed of its own enzyme decomposition, so even if the fresh sea clam is caught at the same time, some have crystal rods and some do not.

1 razor clams white belly in the yellow part of the razor clams is the glandular organs of razor clams, there will be sand in it, it is best to deal with it before eating, soak the clams bought in light salt water, you can spit out the sand, after the water boils, blanch the clams for 10 seconds, the shell will open, and then squeeze out the internal organs to cook.

There may also be parasites on the clams, generally a creature called "clam-eating intestinal fluke", the worm is yellow-white, milky white, about 2 cm in length, the parasitic razor clams are emaciated, can not continue to reproduce, squeezing their abdomen will have more than one living crawl out, but the clams with parasites are cooked at high temperatures, the parasites have already been killed, and the bookkeeper will generally be fine if they eat it.

2 is. The black part of the belly of the razor clams is the same as the black sac in shellfish such as clams and oysters, which belongs to the digestive organs of shellfish, which can secrete and transport digestive juices, contain proteases, lipases and other components, and can also store the energy and substances after digestion, just like the liver of domestic animals, which can be eaten, and the food eaten by razor clams is either digested and stored before entering the liver and pancreas, or it is excreted as an unwanted component.

3 Because the texture of the clam shell is very hard, it is not suitable for consumption; On the other hand, the nutrients in the clam shell are limited, and can not be absorbed and utilized by the human body, and the edible value is not high, and there is a risk of scratching the throat of the mouth if eaten by mistake.

There is a black edge on the outside of the clam shell, which is generally not recommended to eat, because it contains more sediment and bacteria and other microorganisms, which not only tastes poor, but also may easily cause gastrointestinal discomfort.

Although the internal organs of razor clams do not contain toxic ingredients, they are better removed because the internal organs contain some sediment and incomplete undigested food residues, and if they are not removed, eating them with meat will more or less affect the taste.

It is the sperm and egg of a razor clam.

4 is a crystal rod. The white lines in the belly of the razor clams are the "stomach stirrer" of the clam's internal organ, which is called "crystal rod" in the form of a translucent gelatin-like rod, about two or three centimeters long, and about a quarter of one end of it will be bloody.

The crystal rod of razor clams is attached to the pouch in the stomach at one end and outside the body at the other end, and has two main functions. When the razor clams eat, the crystal rod is used as a blender to drive the peristalsis of the stomach and intestines and promote the digestion of food; When razor clams are hungry, the crystal rod will automatically dissolve and be used to satisfy hunger. Generally, razor clams that have been placed for a long time will not have crystal rods in their bodies, and razor clams will cause the crystal rod to dissolve in the order of dissolution time due to the speed of their own enzyme decomposition, so even if they are fresh at the same time, some have crystal rods and some do not.

5 The opening of the razor clams is not necessarily dead.

1. There are two situations for the opening of razor clams, one is to carry out the usual physiological activities of the slag pants, such as predation and excretion, usually the clam shell is opened, and the inlet pipe and outlet pipe are stretched out to carry out normal physiological activities;

2. Another situation is death, after the death of the clams, the muscles on the clam shell lose their activity, and the clam shell cannot be tightened, and then there is an opening.

6 razor clams can be stored in the refrigerator.

Fresh clams are generally not stored in the refrigerator, but the razor clams of Death Liangyuan are stored in the refrigerator, which can reduce the growth rate of bacteria and prolong the shelf life; In this way, the razor clams can be preserved for a longer period of time.

One of the clams that is transparent is not a parasite.

A transparent thing in the razor is not a parasite, but its crystal rod, which is edible, which is rich in a lot of protein and rich enzymes, has high nutritional value, and can help the digestion of food in the body when eaten in moderation.

Can you eat all the meat in razor clams? Offal cannot be eaten. Not all meat can be eaten with razor clams, and the internal organs should be removed before eating razor clams, because there will inevitably be a certain amount of sediment in the internal organs of razor clams, and there will also be some undigested food residues.

The white thread in razor clams is an organ in the digestive system called a crystal rod that is edible.

However, not every razor clams have it, because when the razor is hungry, the crystal rod will automatically dissolve and be used to satisfy the hunger. Generally, razor clams that have been placed for a long time will not have crystal rods in their bodies, and razor clams will cause the crystal rod to dissolve in the order of dissolution time due to the speed of their own enzyme decomposition, so even if they are fresh clams caught at the same time, some have crystal rods and some do not.

Unlike parasites, the parasite on razor clams is generally "clam-eating fluke", which is yellow-white, milky-white, and about 2 cm long. The parasitic clams are emaciated and unable to reproduce, and more than one living cram crawls out when squeezed on its abdomen.

The white thread in razor clams is an organ in the digestive system called "crystalline style" and is edible.

Crystalline style is also known as crystal pillar and crystal needle. It is a translucent gelatin-like rod in the digestive tube of mollusks. It contains a large number of digestive enzymes and is the main donor of digestive enzymes.

Although it is widely distributed among many species of Velolida and Gastropoda, the plankton-feeding shellfish are the most significant. It is concentrated in the crystal capsule, and its anterior end extends into the stomach and comes into contact with the chitin gastricshield on the stomach wall. In the living body, it rotates and collides with the stomach shield and grinds, and the enzymes contained in it are slowly released into the digestive juices.

This is best suited for digestion, which feeds on small amounts of plankton at any given time, and oysters are thought to rotate about 70-80 times per minute. Some crystal rods are soluble and disappear when the shellfish are removed from the water (oysters); Some are solid and insoluble (clams, horse oysters). Amylase is the most active of the enzymes contained, in addition to weak cellulases, oxidases, and esterases.

Free of other glycolytic enzymes, lipases and proteases.

This transparent thread is not a parasite, but an organ in the clam's digestive system, called a "crystal rod", which is edible.
