Braised pork is a famous popular dish, which has its own characteristics in all major cuisines. It is mainly made of pork belly, and it is best to make it with three layers of fat and thin meat. The pot is mainly casserole, and the meat made is fat and thin, sweet and soft.

Meat is a good source of various minerals, with high content of elements such as sodium, potassium, phosphorus, sulfur and chlorine, and rich in iron, copper, manganese, zinc, manganese and cobalt, but extremely low content of calcium. Soluble minerals (such as potassium and sodium) are easily lost with the juice during the freezing and thawing process of meat; Iron, copper, zinc and other minerals exist in combination with protein, which is not easy to be lost during processing.
