It must be that the frozen shrimp is heavy, because the frozen shrimp is the product obtained by freezing the fresh shrimp, and the frozen shrimp includes shrimp and ice. Whereas, live shrimp have less moisture.
-
1. The freshness is different.
The protein of chilled shrimp has been partially denatured, and the taste and safety cannot meet the standards of live shrimp.
2. The degree of nutrient richness is different.
Frozen shrimp are not as nutritious as fresh shrimp. Live shrimp is more nutritious, freezing can destroy some nutrients, and long-term freezing can cause the gradual loss of nutrients.
3. Different tastes.
Frozen shrimp are not as tasty as fresh shrimp.
Extended Information: Chilled shrimp: Boil in brine.
Seafood such as fish and shrimp tend to contain bacteria that are resistant to low temperatures, and bacteria can continue to multiply even if they are stored refrigerated. Chilled shrimp protein has been partially denatured, taste, safety are not up to the standard of live shrimp, can be used salt water with green onions, ginger boiled for a period of time, dipped in garlic juice, ginger vinegar juice or mustard juice, can reduce the formation of harmful substances histamine. It's also good to eat it braised or grilled.
Frozen shrimp: Braised in oil and stir-fried. In the process of frozen storage and thawing, the juice in the shrimp is easy to lose, and its umami and taste are not as good as that of fresh shrimp.
Long-term storage is also prone to bacterial growth, so frozen shrimp is suitable for heavier flavors, such as braised in oil, stir-frying, etc. The frozen shrimp has a crisp and tender taste, which can be stir-fried with peas, cucumber, asparagus, etc., and can also be made into cashew shrimp, Longjing shrimp, etc.
Frozen shrimp can be put with some salt or liquor, and then put in the refrigerator fresh-keeping room to thaw; It can also be thawed in the microwave, but be careful not to thaw it repeatedly, otherwise it will not only lose flavor and nutrients, but also be more prone to spoilage.
Frozen shrimp and shrimp should be selected from the production date closer, and the shrimp with blue or white color should be evenly wrapped on the surface of the shrimp with ice; Red shrimp are likely to have been dead for a long time (except for frozen or Argentinian red shrimp after cooking), so avoid buying bright and large ones with too thick ice cubes.
-
There is a certain difference in the weight of ice shrimp and live shrimp, and a refrigerator of the same quality, if it is a frozen refrigerator, it must be heavier, because there will be a lot of ice cubes on the surface of his body.
The doping of such ice cubes can lead to an increase in the weight of frozen shrimp.
-
I think it's heavier under the ice, because of its own weight. It's not very heavy, and if you freeze the shrimp, the information inside him won't be lost. Returning increases the weight of the water, so freezing it is heavier than surviving.
-
Frozen shrimp will be heavier than live shrimp.
-
In frozen shrimp, it is with ice. Live shrimp. Tap.
-
The main reason for buying frozen shrimp is that there is a difference. Frozen shrimp will be relatively cheaper, and you can directly refreeze them when you get home. Let's take a look at the relevant knowledge.
Pick frozen shrimp.
1. Look at the color tone.
Frozen shrimp is divided into two types, one is red shrimp. Red shrimp are shrimp that have been boiled and then refrigerated. For this kind, look at the shrimp brain tone.
The shrimp brain is very bright and not black, it is a good shrimp. And if it turns black, it's not fresh. Red shrimp is cooked, the head is gray-black, and it is frozen after death, and this kind of thing is not allowed.
Dead shrimp must not be eaten, as soon as the crayfish die, the germs will dissolve immediately, and people will be very prone to poisoning and diarrhea after eating. In addition, crayfish carry a lot of histidine, when the crayfish person dies, this histidine will quickly become a toxic substance, and people are easy to cause food poisoning after taking it. Only lobsters that die after being drunk on ice can be eaten.
It's not good to die before an ice drink. Chilled lobsters are mostly refrigerated immediately when the crayfish are alive, although this kind of lobster has passed away, but because of the low temperature, most of them have already been frozen, which will inhibit the growth of edible fungi and slow down the problem of protein spoilage and mildew.
The second type is green shrimp. For this kind. Look at the shrimp head hue. The whiter, blue-white ones are the best, and they don't have to be red, and the reddened ones are not fresh. Black ones are also not very good.
Tips: The reason why the red shrimp in frozen shrimp can be bright red depends on the fact that the shrimp is cooked in advance, and the shrimp is red due to astaxanthin in the body after boiling. The shrimp were already cooked, refrigerated and sold. However, after buying it and melting it, it has to be cooked, and even if it is cooked, it cannot be eaten immediately.
2. Look at the appearance.
Whether it is red shrimp or green shrimp, you can use this way to quickly identify, that is, to see if the shrimp brain has fallen, if all the shrimp are more detailed, the head and tail are closely connected to the human body, indicating that the shrimp is fresher. If the head of the shrimp falls off, the head and body, the shell and the meat are slack, and the head and tail are easy to fall off or separate, which is not fresh.

Summary. Dear, hello, I'm glad to buy shrimp for you, from the nutritional point of view Frozen shrimp after a long time of low temperature quick-freezing, will not cause nutrient loss in a short time, if the freezing time is too long, nutrients will be slowly lost; The cells and activities in the body of live shrimp are all there, and the nutrients can be well retained. It's better to buy live shrimp, I hope mine can help you, thank you for your <>

People like to eat shrimp in daily life, and many people don't know what is the difference between frozen shrimp and live shrimp? Usually, frozen shrimp are not as delicious as fresh shrimp. The differences between frozen shrimp and live shrimp are mainly manifested in:
1. Freshness, under normal circumstances, the shrimp meat of live shrimp looks more elastic and chewy, but the meat of frozen shrimp looks soft. 2. Eating taste, whether boiled or fried, the taste of live shrimp is more delicious, and the elasticity of the meat is more sufficient, but the umami of frozen shrimp is not so strong. Shrimp has a high nutritional value, and most of the shrimp we usually buy in life are frozen shrimp, <>

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.

Chilled (frozen) shrimp is rich in protein, potassium, iodine, magnesium, phosphorus and other minerals, as well as vitamin A, aminophylline, astaxanthin and other components. The effects are:1
Hypolipidemic effect: Chilled shrimp has the effect of reducing serum cholesterol content, which can effectively prevent symptoms such as arteriosclerosis and hyperlipidemia. 2.
Antihypertensive effect: Chilled shrimp has the effect of dilating coronary arteries, which is conducive to lowering blood pressure and preventing symptoms such as myocardial infarction. 3.
Enhance the body's immunity: Chilled shrimp is rich in nutrients, which can provide the body with the nutrients it needs, thereby enhancing the body's immunity.
If it's like this, don't buy frozen prawns, and they don't have nutritional value:
4 types of inferior prawns.
Mainly chilled shrimp and frozen shrimp)
1. The surface is sticky.
If it is a prawn that is frozen immediately after harvesting, it is relatively fresh, and the surface is relatively dry and slightly moist. If the storage conditions are not good, the prawns will easily deteriorate, and they will produce mucus, and the surface will be sticky, indicating that they have been spoiled, and they cannot be eaten, which will harm health.
Some people think that ** is cheap, although the hair is sticky, it will not stick when you wash it at home, this is not right, don't buy it.
2. The smell is wrong.
Prawns live in the sea, and fresh prawns have a faint smell of sea, which is normal. If you smell not a fishy smell, but a sour, foul smell and other peculiar smells, it means that the prawns are not fresh and have produced a large number of bacteria, which will be harmful to health after eating.
3. The ice is too thick.
In general, the ice on the surface of frozen shrimp is very thin, basically there is no ice, if the ice of the prawns is too thick, you should be careful. Such prawns cannot be touched or smelled, and it is difficult to judge its quality. Some prawns are frozen after death, which is not fresh in the first place and is prone to bacterial growth.
There are also some that are repeatedly frozen, not only have many bacteria, but also have a poor taste, and they also take up weight, so you can't give them away for free.
4. The shrimp head turns black.
If the prawns are very fresh, the color is relatively bright, and the color of different prawns is not the same, ordinary prawns and grass prawns are cyan, and the sea-caught prawns are pink, and the shrimp head and shrimp body are closely connected.
If the prawns are not fresh, the connection between the shrimp head and the shrimp tail will be separated, and the shrimp head and even the shrimp body will be blackened, and they will not be able to buy if they are broken.
-
The freezing process is different:Salt-frozen shrimp are frozen separately and then packaged together, and there is no glue between the shrimp and shrimp, while frozen shrimp are frozen together by freezing in water, so there is a big difference.
Secondly, the difference between salt-frozen shrimp and frozen shrimp is also the difference in eating methods, first of all, salt-frozen shrimp is relatively easy to digest, but it is not suitable for cooking because it is too salty, while frozen shrimp is different, with a good taste and easy to cook, and salt-frozen shrimp is best washed and then boiled, because direct cooking will produce a lot of salt, and eating more high-salt food is not good.
Precautions for frozen prawns
It is best not to drink a lot of beer when eating frozen shrimp, because that will produce too much uric acid, which can cause gout. Seafood should be eaten with dry white wine, because the fruit acids in it have the effect of sterilizing and removing fish.
When eating frozen shrimp, it should be cleaned, the shrimp line on the back of the shrimp is the waste of the shrimp that has not been excreted, if you eat it There is a muddy smell in the mouth, which affects the appetite, so it should be removed. The color is red, the body is soft, and the shrimp that turns around are not fresh, so try not to buy them. Spoiled shrimp must not be eaten.

Raw jelly. Shrimp is the most common seafood food, rich in protein and other nutrients, after the death of shrimp in the body will be broken down into some toxic substances, long-term storage after eating will be harmful to health. Therefore, it is best to put the shrimp that are not eaten in the freezer, which can effectively reduce the generation rate of toxic substances and keep the shrimp fresh.
-
Shrimp is good for fresh and nutritious shrimp.
1. The cooked and then frozen shrimp have been cleaned and can be cooked directly after thawing; After the direct frozen defrosting, the shrimp threads are washed and cleaned before cooking.
2. Cooked and then frozen shrimp are stored in the refrigerator, which is easy to deteriorate and change taste; Relative resistance to direct freezing.
3. After boiling the boiled shrimp, the moisture in the meat is reduced, and the nutritional value is relatively lost; The loss of nutritional value from direct freezing is relatively small.
-
The shrimp is still fresh and delicious, and the frozen shrimp does not taste good.
-
There is not much difference, saying that the shrimp is more delicious is a rip-off.
Sea shrimp. Frozen well, freshwater shrimp will live well, seawater shrimp will generally die when caught, freshwater shrimp is easy to raise, we all know that eating fish and shrimp to eat alive, but now the shrimp on the market are not natural, eat less better!
The reason why the shrimp is frozen after cooking is because the shrimp can prevent blackheads, sticking and other phenomena after the shrimp are cooked, and keep them fresh to the greatest extent. >>>More
If it is salty, it means that the seawater has not been cleaned, and it was frozen after the death of Zheng Lun. >>>More
The skin of the prawns is not easy to peel after they are fried, it may be that the shrimp have been stored for a long time and are no longer fresh, in this case, the shrimp itself contains less water, and the shrimp skin is tightly attached to the shrimp meat. Shrimp is a very common food, which is cooked in a variety of ways, suitable for frying, frying, stewing, boiling, etc., and the nutritional value is also wrong. >>>More
Recently, in Jiangsu, someone found a fish with a belly facing up and a red tail in a pond in Lianyungang Park. But I didn't know what the name of this fish was, and after consulting experts, I learned that this small fish has a very nice name, called fairy shrimp. Fairy shrimp is actually not a very rare animal, and the footprints of fairy shrimp can be seen in many places around the world. >>>More
