Meat is a primary ingredient in cooking, rich in protein and fat. It is suitable for various cooking methods; whether it's frying, stir-frying, quick-frying, braising, stewing, simmering, or roasting, it can be prepared into delicious dishes. However, if meat is accidentally burned during cooking, its protein will be converted into many harmful chemical substances. Once these harmful substances enter the human body, they can damage normal physiological functions. At the same time, other high-molecular compounds in the meat, due to incomplete combustion, can produce some carcinogenic substances. Therefore, special care must be taken when cooking meat to avoid burning it. If it is burned, it must absolutely not be eaten and should be discarded.
