When we buy pork in the market, we will find a seal on the pork, indicating that the pork has passed the inspection of the quarantine department and can be sold. But the stamps on pork are also divided into red and blue. So, what's the difference between red and blue stamped pork? Next, let's listen to what "insiders" said to Bian Xiao!

First of all, the insider said: the red stamp is female pork and the blue stamp is boar. If the pork is covered with a round red seal, it means that pork can be purchased and eaten with confidence. Although the colors of seals in some areas are different, the meaning of seals is the same, which means that they are all legal pork after quarantine.

Secondly, in addition to the round seal, there are some different shapes of chapters. For example: long knurled seal, triangular seal, oval seal and so on. . Never buy pork with oval or rectangular seals! There is also a kind of chapter that pays special attention to the "X" shape, which is impossible for us to see in our daily life.

So, are the marks on pork edible? The seal on pork is edible, and the colored seal on pork is made of food pigment, which is not easy to erase and can be safely eaten; Moreover, fake seals are easy to erase, and everyone should pay attention to this.

What Bian Xiao finally wants to say is that the color of the seal on pork is only to distinguish different regions, not to distinguish the quality of pork. If there is any stamped pork on the market, it is proved to be the old mother's pork or dead pork. In short, you'd better know before buying.
