First course: buffalo.

Have you noticed that some beef in the market looks watery, as if it had been sprinkled with water? This is actually caused by beef flooding, so if you see such beef in the market in the future, don't buy it again.

Second: dry wrinkled beef

It says never buy beef with water on its surface. Now I want to tell you, never buy beef that looks dry and wrinkled. This is also caused by water. This kind of beef is usually beef that has been watered for a long time. Because water injection destroys the water balance in beef cells, beef looks dry and wrinkled.

Third: the surface color of beef is uneven.

For beef, it is difficult to ensure uniform water injection, so some beef may have color difference. Look carefully, one is deeper and the other is lighter. Use the "flashlight" function of the mobile phone to take a picture, and block it with the other hand. The red and yellow lights in the market show that some beef is not very uniform in color. This kind of beef must be water-injected beef. Don't buy it.

Fourth: beef, especially moist.

Feel beef with the back of your hand. If you find that the surface of beef is particularly wet, don't buy it This means injecting water into beef, and the injected water will flow out. Of course, this moisture is different from ordinary beef. This kind of water-injected beef is particularly moist, which is different from ordinary beef.

At the same time, you will also find that some beef not only has no water, but also has some sliminess. You shouldn't buy such beef. Sticking beef is because it has been stored for too long and some beef is broken. At this time, we put our nose in front of the beef and smell it. You will find that the beef has a sour smell.

Fifth: beef that can wet paper towels.

This trick, everyone must prepare a prop, that is, paper towels. When you buy beef, put a paper towel on it and seal it with tape. If the paper towel is not wet, the beef is normal. If the paper towel is soaked, there is something wrong with the beef. This is probably water-injected beef.
