In our lives, fresh shrimp is an extremely common seafood product with high nutritional value. Many people will go to the supermarket to buy some fresh shrimp and put it at home for later use. This kind of fresh shrimp is often eaten as food by many families. However, when some friends were cleaning the live shrimp they just bought, they found that there was something like glue on the live shrimp after washing. So what is the glue-like substance on live shrimps after they are washed? It turns out that this is a kind of "glue-injected shrimp". The glue inside can not only increase the weight of the shrimp, but also prevent the shrimp head from being dented or collapsed after being chilled, making the shrimp look fuller and fresher. Next, let me introduce the method of identifying normal shrimp and plastic-injected shrimp.

Step one:

First we look at the head of the shrimp. Under normal circumstances, the heads of normal frozen shrimps will be flat or not bulging, but the heads of glue-injected shrimps are very bulging, that is, they swell very much. Most of these shrimps are glue-injected shrimps.

Step 2:

Press the body of the shrimp. After pressing, normal fresh shrimp will feel like it is sinking, and it will be difficult to bulge up after a while, but the glue-injected shrimp is pressed. After that, there will be an obvious rebound with a short rebound time and obvious rebound effect.

Step 3:

We can also take off the shrimp heads and take a closer look at them. Normally, shrimps will have red heads after being frozen. If the shrimp head is frozen into a ball and does not look like a normal shrimp brain, it is usually a glue-injected shrimp.

Step 4:

We peel the skin again to see if the skin of normal shrimps will feel connected when peeled off. However, the glue-injected shrimps have glue, so it is easier to separate the meat and skin. Come.

It should be noted that most vendors use edible gelatin for glue-injected shrimp, which usually does not cause harm to human health. If the glue-injected shrimp is added with industrial glue, it may contain heavy metals and carcinogens.
