Beef is a high-quality protein food that helps maintain and develop muscle mass. In addition, beef is a source of diverse vitamins and minerals such as vitamin B12, zinc, iron… as well as some bioactive compounds (taurine, creatine…).

Beef can be prepared into many different dishes, such as boiled, stir-fried, stewed, braised, or used in noodle soups… all of which are delicious. However, have you noticed that sometimes pieces of beef will have a rainbow-like color, why is that?

Many people believe that these pieces of beef are poisoned, contaminated, and cannot be consumed. A member of a culinary forum said that her family runs a noodle soup shop, and when they serve freshly cooked beef slices, sometimes customers think they are selling spoiled meat and refuse to eat it because of the rainbow-like appearance on the beef slices.

So, can you eat beef that has a “rainbow” appearance?

The answer is that the beef with rainbow-like colors is “completely normal” and can be eaten.

Sometimes, when beef is cooked through, it reflects light and creates the phenomenon of light refraction. This phenomenon occurs completely randomly and is not dependent on the conditions of cattle farming or the processes of preserving and cooking the beef. This is the conclusion of the United States Department of Agriculture (USDA).

Specifically, when you cut a piece of beef, the light contacts the fat and iron on the cut surface, causing the light rays to bend and create a rainbow-like appearance. The USDA’s research also indicates that not only beef but also pork, fish, smoked meat, and ham… can exhibit this phenomenon, as all of these meats have light reflection factors when exposed to heat.

Researchers say that this phenomenon is completely normal, and even pork, fish, and other meats can experience similar situations.
