The shrimp meat is already pink, does it mean that the shrimp is no longer fresh?

Fresh shrimp, the shell should be blue-gray, transparent and shiny, head and body.

Tightly connected. If the shrimp shell has turned red and the head and body are broken, it is better not to buy it. When buying shrimp, you should also pinch it with your hands to judge the freshness of the shrimp by the feel and elasticity of the shrimp meat: fresh shrimp meat is elastic, and fresh shrimp meat is often dry and soft.

When buying shrimp, you must know how to distinguish its freshness, the fresher the shrimp, the more delicious it is, otherwise the umami will be lost and the meat will be "moldy". Fresh shrimp, the shell and muscles are very tightly sticky, when peeling the shrimp meat by hand, it takes a little effort to peel off the shrimp shell, the shrimp intestine tissue and shrimp meat of fresh shrimp are also sticky tightly, but the intestines and meat of refrigerated shrimp are not very tight, if the shrimp intestines and shrimp meat are loose, it means that the shrimp is not fresh. There are also those whose gills have turned black, most of which are diseased shrimp.

One is that the body shape is best curved.

Fresh prawns, head and tail as well as body are all in one piece, with no signs of loosening. We all know that prawns are curved, you have to pay attention, prawns with a certain degree of curvature are the best and are elastic. Like stale prawns, the head and tail of the shrimp and the body of the shrimp are not so tight, and there is no initial curvature, so this method is very effective in identifying fresh prawns.

Second, the body surface needs to be dry.

Fresh prawns are clean and dry by hand. If it is a stale prawn, it will be slimy to the touch, that is, the price can be cheaper, and we should not choose to buy it, because eating it will also be bad for the body.

The third is to choose bright colors.

There are many different types of shrimp and their colors are also different. Like fresh prawns.

Grass shrimp are green in color, but bamboo shrimp.

Jiwei shrimp not only have a black and white pattern, but also have a pink color. If the shrimp is black, then the shrimp is not fresh, if the color of the whole shrimp is black, then "congratulations", the shrimp has deteriorated.

Fourth, the shrimp shell is closely connected to the meat.

The fresh shrimp shell and the shrimp meat will be very sticky, we need to use force to peel off, if we usually eat shrimp is particularly good to peel the skin, then it proves that the shrimp you eat may not be very fresh.

Because when we eat prawns if they are not cooked, they will carry bacteria and parasites, so we must eat them thoroughly before eating!

Yes, shrimp is generally white when it is fresh, and it may have spoiled when it starts to change color, so it is not recommended to eat it at this time, otherwise it is easy to cause food poisoning.

There are all kinds of shrimp jumping, and the shrimp head turning red is not fresh. Shrimp is a favorite food for many people, which means that the shrimp has gone bad. Whether it is live shrimp or frozen shrimp, it means that the freshness is declining, and the color of raw shrimp changes at room temperature.

If you leave it for too long, it's close to spoilage! The fresh shrimp meat is delicious and elastic! Therefore, it is best to buy live shrimp to eat shrimp, and you can put it live for a week if you put it live, and you can eat it and take it out to thaw it!

But it has to be alive! It's better not to eat dead shrimp! There may be bacteria that die of seafood with shooting, especially those that have been broken, which are fast to spoil, so eat Tan Sheng Envy with a powdery taste, and there is no shrimp taste.

There are two scenarios:

1. Normal phenomenon.

It may be normal for shrimp to turn black after thawing. Because shrimp meat contains polyphenol oxidase, this substance will produce melanin when frozen, which will cause the shrimp head to turn black, and the shrimp meat can continue to be eaten, but the taste will deteriorate.

2. It has deteriorated.

The shrimp turn black after thawing, probably because of spoilage. In the process of freezing, the shrimp has deteriorated, so that the bacteria multiply in the shrimp meat, and after thawing, the bacteria are not controlled by low temperature, and the reproduction speed is accelerated, so that the phenomenon of blackening appears and cannot be eaten again.

Put the purchased shrimp in a pot, add an appropriate amount of sugar, stir well, put it in a plastic bag, seal it, and freeze it in the freezer compartment of the refrigerator. This method is very useful for preserving shrimp, it does not affect the taste.

Fresh prawns can last in the refrigerator for a day. If left out for a long time, they will still change color, which will affect the taste. Therefore, when buying seafood, it should be eaten in time, and Yuanliang cannot be stored for a long time.
