From the perspective of color:

Compared with pork, fresh beef has a darker overall color, redder color, glossier meat, and white or milky yellow fat color. The color of fake beef is relatively lighter, the meat color is uneven, and the muscle fibers are dull.

If it is cooked beef: the beef will turn white when exposed to oil, and the surface of pork soaked in beef paste will begin to turn yellow when exposed to hot oil.

(2) Pick from the smell:

Pork has a unique sweetness, while beef has a small fishy smell. Fake beef will smell weird, and stale meat will have a rancid smell.

(3) Judging from the feel:

To the touch, beef is relatively hard and pork is relatively soft. Take a knife and cut the two pieces of meat along the grain. You will find that beef is difficult to cut, while pork is easier. Looking at the cut surface of the meat, the texture of the beef is rough, the meat is compact, and the lines are clear and long. And after the real beef is pressed, it has good elasticity and can return to its original appearance. The cut surface of fake beef is smooth and tender, but the meat is loose and has poor elasticity. The edges have fallen apart. The meat's resilience is obviously not strong and it cannot return to its original appearance. The meat is also thicker and feels slimy and uncomfortable to the touch.

(4) Judging from the taste:

Generally speaking, beef meat is difficult to chew and tastes chewy. The fiber length of beef is longer, and the meat structure is thick and compact. When eating beef, the meat feels old, and when eating pork, the meat feels tender. Fake beef tends to fall into small pieces when cooked, tastes like bean dregs, and tastes bad when chewed

In addition to the above aspects, you can also use the conversation with the boss to tell the difference. You can chat with the boss and find out where the beef comes from and when it was purchased. If you often buy meat from the same store and are familiar with the boss, you can ask for relevant information. Generally speaking, when facing old customers, the boss will have a customer retention mentality and will answer your questions candidly. However, this article is relatively ineffective for cunning and cunning bosses. But through his answers, you can observe whether he is lying. A dishonest boss will find it difficult to sell good food, so be careful when purchasing.
