For most people in inland citiesBecause live shrimp are generally expensive and difficult to store, they are keen to buy frozen shrimp in supermarkets.
Then there is a problem, everyone patronizes cheaply,Is this shrimp really fresh? This stopped a lot of people.
How do you judge? In fact, it is very simple, everyone pays attention to whether the shrimp is "curved" or "straight".
After all, the shrimp in these two states are very different in all aspects!
The statements in this article are all reliable**, which are repeated at the end of the article.
It depends on the freshness of the shrimp in both "straight" and "curved" states, which we generally use to identify frozen shrimp.
Because for live shrimp, it is very intuitive whether they are fresh or not, whether it is by their activity or smell, it can be easily distinguished.
But if it's frozen shrimp, because they're dead and covered in a thick layer of ice, it's hard to tell for sure.
Some people may feel thatFrozen shrimp is dead shrimp, you go to ask it to be fresh, won't it be outrageous?
It is true that there is a little bit of it when we look at it this way, but if we say that the purpose of our judgment is to discernIsn't it better to understand the two cases of "live shrimp directly frozen" and "dead shrimp frozen"?
If the live shrimp is directly frozen, the cells and muscles of the shrimp are still in an active state and can expand and contract normally.
In this case, the shrimp's body is bent in most cases. Because today's various pneumatic, liquid nitrogen freezing and other equipment can approach the effect of "instantaneous" freezing.
At this time, the live shrimp will be frozen in its most primitive form because the body has not yet reacted.
And for shrimp that have died before freezing, their form has long been out of control.
In addition, the muscles have lost their activity and are already in a limp state, and at this time they generally do not bow over their bodies but are long.
Of course, when they are put into the freezer trayIt will cause changes in the state of the body due to artificial fixation.
In fact, there is no need to worry, the state at this time will be easier to distinguish, because in the case of its own muscles cannot be controlled, the shape of the shrimp will become very unnatural.
If it is a dead shrimp that has been frozen in large quantities and tries to sell it, the form of this part of the frozen shrimp must be crooked, and if this is the case when you see it in the freezer, it is recommended that you buy it with caution.
Of course, in addition to this kind of frozen shrimp wrapped in ice in the supermarket, there is also a kind of "chilled shrimp" that also needs our special attention.
The shrimp we see in the supermarket is a live shrimp in the aquarium, which is more fresh and guaranteed, and of course, it will be more expensive.
There is also the frozen shrimp mentioned above, which is directly in the freezer for everyone to choose. It is very easy to buy and store at home, and it is very easy to judge whether they are fresh or not by using the methods taught above.
There is also a common oneIt is a "fresh shrimp" sold on ice。Compared with live shrimp, they have lost their lives, and frozen shrimp do not have a heavy ice wrap, and they can be eaten directly without thawing when they are bought home.
Normally, they should be frozen from live shrimp for easy transport and storage. Within a certain period of time, it can be thawed daily on demand and then sold on ice-covered shelves.
If you can ensure that they are in stock before freezing, the nutritional value of these chilled shrimp is no different from that of fresh shrimp.
On the contrary, because these shrimps have run out of gas, it will be more convenient to remove the shrimp line and trim when they return home.
However, during this period, it is inevitable that some unscrupulous merchants will freeze some dead shrimp and sell them again.
If the dead shrimp is frozen, we can also judge it by the two forms of "straight" and "curved" that we gave to you earlier.
But now these shrimps have no ice shells, so they are exposed to the fresh shelves, and the shape is no longer the most primitive.
At this time, if we want to tell if they are new or not, we have to change our thinking.
The first thing is to look at the connection between the shrimp head and the body, although the chilled shrimp has undergone a series of tosses of freezing and thawing, the state must be greatly reduced.
However, for shrimp that are frozen alive, the impact is minimal.
Rather, it is the shrimp that have died before they are frozenThe state itself is not good, and the body muscles are also very relaxed。After freezing and then thawing these operationsMost of the shrimp heads and bodies are in a state of imminent detachment
We can use this as the most standard for selecting shrimp, and select those shrimp heads that are more firmly connected to the neck, which will generally be fresher.
The second is to gently pinch the body of the shrimp when selecting the shrimpFeel whether it is very soft or not, these are the states that only stale shrimp have.
High-quality chilled shrimp are directly frozen from live shrimp, so the meat is firmer, and this will not happen in the short term even after repeated thawing.
Of course, even if the shrimp are frozen, they need to be eaten as soon as possible, because the longer they are stored, the worse the quality will become.
I learned how to choose shrimp, and the production of shrimp after buying it home is also a university question, for our health, there are some places that must be paid attention to!
Be sure to wash the shrimp thoroughly before cooking to avoid food poisoningOr because of the water area where the shrimp originally lived, there are bacterial residues.
When eating shrimp, many people will think that they have so much money to buy shrimp, and it is a pity to eat shrimp tails with such a big head.
So even the shrimp head can be eaten, and it will never be let go.
This practice is wrong because the internal organs of the shrimp are all present in the shrimp headTherefore, the substances absorbed by shrimp in the water will be stored in the shrimp head, and the heavy metal content in the shrimp head is much higher than that of shrimp meat.
On the contrary, everyone thinks that the shrimp line is dirty, but in fact, there is no safety problem. It may be because it affects the taste and appearance of eating, so everyone generally picks the shrimp line before making it.
When we make shrimp, we are the same as all seafood or parallel goods, try to ensure a "fresh" word, and pursue the original taste.
Boiling and steaming are generally the best ways to eat, try not to eat fried.
However, it still depends on personal preference, because for today's young people, it seems that eating happily and satisfying their appetites is more important than health.
There are also many people who say that shrimp and vitamin C will have any contraindications when they are eaten together, but after understanding them, they found that they are all nonsense.
Many ** people feel that the protein content in shrimp is high, and it is not easy to gain weight after eating. But everyone must pay attention to not eating too much, otherwise it will be counterproductive, because carbohydrates and vegetables are equally important.
In life, do you like to buy fresh shrimp or frozen shrimp? I hope that the method of selecting shrimp with "bending" and "straight" in this article can help everyone get out of the misunderstanding of buying shrimp and make our health more secure.
