[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. [14]
The smoke point, also referred to as the burning point, is the temperature at which an oil or fat begins to produce a continuous bluish smoke that becomes clearly visible, dependent upon specific and defined conditions. [1]
In addition, hot food must be held at a minimum interval of 135 °F (57 °C) if it is not immediately consumed. The temperature must be checked every 4 hours or else labeled with a discard time. Although monitored hot food can be held indefinitely in this way without a food safety concern, the nutritional value, flavor, and quality can suffer ...
Since fixtures using discharge type lamps produce a light of a considerably higher color temperature than do tungsten lamps, using the two in conjunction could potentially produce a stark contrast, so sometimes fixtures with HID lamps, commonly producing light of 6000–7000 K, are fitted with 3200 K filters to emulate tungsten light. Fixtures ...
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. If raised to a high enough temperature, meat blackens from burning .

So, when choosing a cooking oil, it is important to match the oil's heat tolerance with the temperature which will be used. [23] and to change frying oil a few times per week. [22] Deep-fat frying temperatures are commonly in the range of 170–190 °C (338–374 °F), less commonly, lower temperatures ≥ 130 °C (266 °F) are used. [24]
