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.

A meat thermometer or cooking thermometer is a thermometer used to measure the internal temperature of meat, especially roasts and steaks, and other cooked foods. The degree of "doneness" of meat or bread correlates closely with the internal temperature, so that a thermometer reading indicates when it is cooked as desired.
[11] [12] To prevent time-temperature abuse, the amount of time food spends in the danger zone must be minimized. [13] A logarithmic relationship exists between microbial cell death and temperature, that is, a small decrease of cooking temperature can result in considerable numbers of cells surviving the process.

The beef is usually kept for a period of 4 to 10 days in wet aging. Modified-atmosphere packaging (MAP) is usually employed for the vacuum packaging of meat; typically between 60 and 80 percent oxygen to retain its appetizing color, with red meat such as beef needing a higher oxygen level than less vividly colored meat such as pork.
As the USDA cautions, though, any foods left outside the refrigerator for longer than a two hour time span (or a single hour in temperatures above 90°F), should not be refrozen.
