Why are marine shrimp cheap? Why are frozen shrimp cheaper than live shrimp in supermarkets?

Affected by the epidemic, imported shrimp dare not eat, and freshwater farmed shrimp dare not eat, resulting in marine prawns, cheap.

Prawns are not only delicious, but also a very nutritious tonic, rich in calcium.

and a variety of trace elements.

The protein content is also very high, especially suitable for the elderly and children to supplement the body, the prawns on the market are generally divided into two kinds, fresh live shrimp and frozen shrimp, whether it is live shrimp or frozen shrimp, you must pay attention when buying shrimp, see clearly and then buy, there are 4 kinds of shrimp can not be bought, especially the fourth, no matter how cheap do not buy.

The first type: don't buy the shrimp whiskers and shrimp legs that fall off when they touch them.

Fresh prawns are closely connected to the shrimp legs, shrimp whiskers and shrimp bodies, even if they are frozen shrimp, after thawing, it is also like this, but if the shrimp legs and shrimp whiskers of the prawns are easy to fall off with a light touch, such shrimp should not be bought, because this kind of shrimp is generally a large shrimp that has been stored for a long time, or it has been thawed many times.

The second type: don't buy prawns that are sticky to the touch.

Even the freshly thawed prawns are dry and non-sticky to the touch, if you encounter prawns that are very sticky to the touch, don't buy them, even if the vendors say they are overjoyed, don't believe that it's good to wash them at home, such prawns have been spoiled for a long time, for the health of your family, don't buy this kind of shrimp.

The third type: Don't buy prawns with peculiar smells.

When you buy shrimp, smell it, fresh prawns don't smell like a faint fishy smell, if they smell a peculiar smell or smell, don't buy such prawns, which are generally stale prawns are processed and sold.

Fourth: Do not buy prawns with black hair.

This is the most important, if you see that the shrimp head of the prawns has turned black, this kind of prawns must not be bought, such prawns are prawns that have been stored for a long time, and they have deteriorated and are not fresh, or the growth environment of the prawns is not good, so that the heavy metals of the prawns exceed the standard, so we must remember that such prawns must not be bought.

Because there are fewer people buying shrimp. And the new crown epidemic also has a certain reason. The more goods there are, the cheaper they are.

Sea shrimp and river shrimp are nutritious and delicious in meals, but they are affected by many external factors; As for the deliciousness and nutrition of shrimp, there will not be much difference, if you like to eat it, you don't have to compare it to river shrimp or sea shrimp. At the same time, when selecting, we should first pay attention to whether the shrimp shell is stiff and shiny, whether the shrimp head and shell body are tightly attached to the shrimp body, hard and strong, and whether there is peeling; In addition, it is also necessary to pay attention to the firmness and elasticity of the shrimp flesh.

It's not cheap, such as a big lobster, a few hundred yuan a catty, very expensive.

The first reason: the cost of fresh prawns is high.

The fresh prawns caught from the water must be sold on the same day, if you don't add some other things, you must sell them on the same day, otherwise the prawns will easily die, so the fresh live prawns ** are generally more expensive, because there is a preservation cost there, and the prawns must be put oxygen in the water. Fresh prawns also have a certain mortality rate.

The second reason: fresh prawns have a poor taste, so it is better to cover them.

Although fresh prawns and shrimp are similar in terms of nutrients, but in terms of taste alone, fresh prawns are more delicious, and after the shrimp is frozen, it is not fresh, losing the original freshness of the prawns, and the meat quality is much worse than that of fresh prawns, so frozen prawns are sold cheaper. There are many dishes that cannot be made with frozen shrimp, such as Longjing shrimp, which must be made with shrimp from fresh live shrimp. It tastes better this way, but if you use frozen shrimp, you will find that the meat quality is not only poor, but also fishy, and it is not as delicious as fresh prawns.

The third reason: frozen shrimp are made in batches, and the cost is low.

Frozen shrimp is generally a lot of prawns at one time, and its cost is relatively low, because the more you want, the cheaper it is. If you buy so many prawns at once, it is difficult to sell them if they are fresh, but if you make them into shrimps, you can sell them slowly by putting them in cold storage. The cost is low, and the ** will naturally be sold cheaply.

The fourth reason: most of the frozen shrimp are farmed.

A lot of shrimp are made of farmed shrimp, which is fresh and not fresh, without selection, plus the density of farmed shrimp is relatively large, the taste will be much worse, and naturally ** is cheap.

Sea shrimp is more expensive, sea shrimp live in the sea, fishing is difficult and costly, river shrimp can be artificially farmed. The flesh of sea shrimp is elastic and more delicious, and it is large, so it will be more expensive.

Shrimp has always been very popular with everyone, and now there are many types of shrimp on the market, including sea shrimp and river shrimp, although both of these are shrimps, but there are still certain differences between the two.

In fact, if you compare the sea shrimp with the river shrimp, the ** of the sea shrimp is lower than the ** of the river shrimp.

River shrimp, the main growth environment is our country's rivers, lakes or reservoirs and ponds, so for the river shrimp its growth environment is very limited, and the main growth environment of sea shrimp is China's Yellow Sea, Bohai Sea and Yangtze River Basin, so relative to the living environment of river shrimp, the living environment of sea shrimp is relatively large, and in recent years, our country's lakes and rivers are very easy to be polluted, so it has led to the pollution of the growth environment of river shrimp. Therefore, the number of river shrimp will decline significantly, and now in this era, it is rare and expensive, and the sea shrimp sold now are generally frozen, so the freshness is not as good as the river shrimp, so the ** of the river shrimp is higher than the ** of the sea shrimp.

Under normal circumstances, river shrimp is more expensive than sea shrimp, that is, in the wholesale market of aquatic products, the price of various seafood will fluctuate every day, not that it has always been the same, there are many factors that affect the price, if you love to eat, don't think too much about this issue.

Look at the species, there are many types of shrimp, some are more expensive than river shrimp, and some are cheaper than river shrimp.

What kind of shrimp is this, river shrimp or sea shrimp Is it expensive I bought it in Shanghai. That's the time. Wrasse shrimp, also called pipi shrimp. It's not expensive, dozens of yuan a catty. You can salt and pepper, you can boil it in plain.

Wrasse shrimp, also called pipi shrimp. It's not expensive, dozens of yuan a catty. You can salt and pepper, you can boil it in plain.

The ** of river shrimp and sea shrimp is affected by many factors, such as the taste, taste, nutritional value, quality, freshness of shrimp, etc. On the whole, the ** of sea shrimp is slightly more expensive than that of river shrimp.

The entry for sea shrimp is to live in the sea, and river shrimp to live in rivers and streams.

Sea shrimp to white shrimp entry as the main species, river shrimp to giant river shrimp entry as the main species, they all belong to the long-arm shrimp entry family, the appearance is very similar, but its taste and texture are quite different, so the market ** is also quite different. There is an old saying among the seaside people: "Don't put salt in boiling crab, don't put water in shrimp", the taste of prawns is better than boiled shrimp, and the shrimp meat is tender and has no fishy smell.

When it comes to prawns, it is everyone's favorite delicacy, and is considered by foodies to be the "treasure of food", because it is rich in protein, the nutritional value is extremely high, its meat is as soft as fish, easy to digest, and there is no fishy smell and bone spurs, and it is rich in calcium, phosphorus, iron, magnesium and other trace elements needed by the human body, which has a certain protective effect on the heart and blood vessels.

Among the most expensive freshwater shrimps, Huajinxiu lobster, commonly known as lobster, flower lobster, mountain prawn, Yamato prawn, sand prawn, etc., is a kind of lobster family - lobster. Body length can reach 55 cm.

The abdomen, first antennae, and gait have black-brown and yellow markings. There are four pairs of wart spines at the base of the antennae, and a smaller pair at the back. The body color is colorful and bright.

The appearance of this lobster is very special, the whole body is blue-green, the limbs are black and white, and there are many yellow spots, colorful, generally three to six pounds. When the fishermen were lucky enough to catch this shrimp, they couldn't recognize what it was, and someone once sold it for a sky-high price of 600,000 yuan.

Freshwater shrimp blue lobster is also expensive.

It belongs to the genus Cheleralica lobster, which is a rare genetic mutation of American lobster, which produces an excess of protein, which reacts to form the blue compound astaxanthin, which gives the shell a bright blue color. On average, only one in 2 million lobsters will appear blue, making it a rare marine creature comparable to a living fossil.

This whole body blue shrimp is extremely rare, it is said that only one in two million can be encountered, rare is expensive, so its ** is also very expensive, up to 800 yuan per kilogram 1000 yuan, such a unique color on the table symbolizes full of nobility and taste.

Lobster Nutritional Value:

Lobster is rich in high-quality protein, and the meat is soft and easy to digest, which is a better food for some people who are weak. Lobsters are relatively nutritious, and regular consumption has the following benefits for the human body:

1. Lobster is sweet and salty and warm, enters the kidney meridian, can benefit sperm and blood, tonify kidney yang, nourish yin fluid, have the effect of tonifying the kidney and strengthening yang and nourishing yin, and has a certain alleviating effect on some symptoms such as impotence and kidney deficiency and tetany.

2. Lobster has a sweet taste, peaceful medicinal properties, and can calm the liver and calm the heart, calm the nerves, and have a certain effect on some symptoms such as neurasthenia and insomnia.

3. Lobster is fresh and appetizing, has the effect of strengthening the stomach and eliminating appetite, and has an auxiliary effect on some symptoms such as weak stomach and loss of appetite.

I think it's lobster, because the lobster is relatively large, many lobsters are not considered economic seafood, because it is difficult to breed, so it determines its higher price, unlike some freshwater shrimp, which are easy to feed, so it is not so expensive.

Reason:

First, the home is far away from the market. Some elderly people don't go on the market often, and they buy it no matter how good or bad it is.

Second, some can't see fresh live shrimp, and the seller itself sells frozen shrimp in cold storage.

3. There is a big difference between frozen shrimp and fresh shrimp. Comparatively speaking, frozen shrimp is cheaper than fresh shrimp.

Fourth, the frozen shrimp is preliminarily processed, and it can be directly put in the refrigerator after being bought home.

1. Refrigerated storage of frozen shrimp.

Shrimp are frozen in the refrigerator and can be wrapped in plastic wrap for better storage. However, the storage time of shrimp should not be too long, because it is easy to be air-dried after a long time, which will affect the taste.

2. Defrosting method of frozen shrimp.

If you want to achieve a good thawing of frozen shrimp and prevent its nutrients from being excessively lost or destroyed, you can put the shrimp under tap water and rinse it with a small core rotten droplet, or sprinkle some salt in the frozen shrimp, which can reduce the destruction of its nutrients.

3. Frozen shrimp is best boiled in salt water.

If you buy frozen shrimp, the most suitable cooking method is to boil it in salt water, and be careful to cook it for a long time to ensure that the Vibrio parahaemolyticus in it is killed. Be careful when buying, don't buy if the protein in the frozen shrimp meat has oxidized and blackened in the air.

Since the issuance of the 2015 Notice on Adjusting the Safety Risk Monitoring Measures for Some Imported Edible Aquatic Animals, the Shanghai Airport Inspection and Quarantine Bureau has suspended the entry of Penaeus monodon in the transit site related to the epidemic as required, and tightened the monitoring of the imported grass shrimp in other transit sites in Vietnam. Later, the ban was lifted, and it can be imported again.

According to the information on food products that were not allowed to enter the country released by the General Administration of Customs, in November 2020, a total of 10 batches of food were not allowed to enter the country due to the detection of animal diseases. Among them, two batches of Ecuadorian frozen raw South American white shrimp imported by Songjia (Dalian) Seafood Sales **** (hereinafter referred to as "Songjia Seafood") and produced by Sociedad Nacional Degalapagos were not allowed to enter the country at Dalian and Qingdao ports respectively.

At the port of Nanning:

And at the Fuzhou port, it is ****** by Fujian Tiangang International from Tien Hung Kien Giang Co, LTD imported 2 batches of Vietnamese frozen black tiger shrimp were not allowed to enter the country.
