1, I hope. The real beef is fine in texture, even in red color, shiny in meat and milky white in muscle fibers. Fake beef has rough texture, uneven flesh color and dull muscle fibers.

2. Smell. The smell of fresh beef is normal meat, and there is no pungent smell. Fake beef will have a strange smell, and stale meat will have a rancid smell.

Step 3 touch. After the real beef is pressed down, it has good elasticity and can be restored to its original state. Fake beef's cutting elasticity is poor, and it is easy to come apart.

4. Taste. After the real beef is cooked, it looks refreshing and tastes delicate and chewy. Fake beef is easy to break into small pieces after being cooked. It tastes like bean dregs and tastes terrible when chewed.
