What do you mean by the blue seal on the pigskin
4hw.org: when we usually buy meat, we will find red and blue seals on the pigskin. What do these chapters mean? I'll give you a detailed introduction.
The blue is the rolling quarantine seal of the animal quarantine station! The red is the grade seal of the designated slaughtering enterprise! There is no difference in meat! There is a difference in the seal!
Three seals shall be affixed to the raw pork of designated slaughtering enterprises before listing: the blue rolling quarantine seal affixed by the animal quarantine station, the blue purple meat quality inspection seal and the red grade seal affixed by designated slaughtering enterprises.
Therefore, when you go to the market stall to buy fresh pork, you can see that there is a blue or red round quarantine seal on the pork, which means that the pork is free of disease and edible.
However, according to the regulations of the state on the quarantine of meat, except for the blue round quarantine seal, other types of quarantine seals are non-food products. In order to help consumers identify the quarantine seal, this paper introduces the characteristics and uses of the national quarantine seal.
1. The round quarantine seal indicates that the pork is edible after quarantine. In the middle of the chapter, there are four words of veterinary inspection, marked with the words "month day" and "pig". This kind of meat is of good quality and can be sold for eating.
2. The oblong quarantine seal is the edible oil seal, which indicates that this kind of meat can not be sold and eaten directly after quarantine, but can be processed into edible oil, and can only be sold after it is boiled and refined as soon as possible. There are three words of edible oil in the seal.
3. The triangle quarantine seal indicates the high temperature seal. Such meat can only be sold after high temperature treatment within the specified time. There are two words "high temperature" in the seal.
4. The oval quarantine seal indicates the industrial oil seal. The meat covered with this quarantine seal cannot be sold or eaten. It can only be boiled into industrial oil. There are three words industrial oil in the seal.
5. The X-shaped quarantine seal is the destruction seal. The meat covered with this seal is forbidden to be sold and eaten. It should be destroyed in a unified way. There are two words of destruction on the diagonal of the seal.
Whether the pork is good or not, we can not simply judge by the blue chapter and red chapter, but we should observe the color of the pork itself and the elasticity of the skin to choose.
1. It depends on the skin. There are no spots on the skin of healthy pork. There are usually purple bleeding spots on the skin of dead pork, even dark red diffuse bleeding, and some red or yellow bumps.
2. Smell. Fresh pork has the normal smell of fresh pork. No matter in the surface or deep layer of the meat, the deteriorated pork has the smell of blood, putrefaction and other peculiar smell.
3. It depends on elasticity. The texture of fresh pork is tight and elastic, and it will recover immediately after pressing the dent with fingers. The deteriorated pork can't be recovered because it is depressed after being pressed with fingers.
4. It depends on fat. The fat of fresh pork is white or milky white, shiny, and the fat of dead pork is red, yellow or green.
5. It depends on muscles. The lean meat of healthy pigs is generally red or light red, with bright luster and few liquid outflow. The color of dead pork is red and purple, without luster, and there is dark red blood juice exudation during extrusion.
Finally, it is suggested that you buy pork through regular channels.
