Most other countries' beef grading systems mirror the U.S. model, except for those in the European Union (EU). The EU employs a grading scheme that emphasizes carcass shape and amount of fat covering [4] instead of marbling and aging. The differences in grading yield incompatible value judgments of beef value in the United States and the EU. [5]
Food grading involves the inspection, assessment and sorting of various foods regarding quality, freshness, legal conformity and market value.

As meat cooks, the iron atom loses an electron, moving to a +3 oxidation state and coordinating with a water molecule (H 2 O ), which causes the meat to turn brown. Searing raises the meat's surface temperature to 150 °C (302 °F), yielding browning via the caramelization of sugars and the Maillard reaction of amino acids.
Beef is classified according to different parts of the cow, specifically "chest lao" (the fat on the front of the cow's chest), "fat callus" (a piece of meat on the belly of the cow), and diaolong (a long piece of meat on the back of the beef back), "neck ren" (a small piece of meat protruding from the shoulder blade of a beef) and so on.

High grades represent high projected levels of tenderness, juiciness, and flavor.
