may be used. Deep frying may also be performed using oil that is heated in a pot. Deep frying is classified as a hot-fat cooking method. Typically, deep frying foods cook quickly: all sides of the food are cooked simultaneously as oil has a high rate of heat conduction. The term "deep frying" and many modern deep-fried foods were not invented until the 19th century, but the practice has been around for millennia. Early records and cookbooks suggest that the practice began in certain European countries before other countries adopted the practice. Deep frying is popular worldwide, with deep-fried foods accounting for a large portion of global caloric consumption.

Technique

Deep frying food is defined as a process where food is completely submerged in hot oil at temperatures typically between and , but deep frying oil can reach temperatures of over 400 °F (205 °C).  One common method for preparing food for deep frying involves adding multiple layers of batter around the food, such as cornmeal, flour, or

; breadcrumbs may also be used. While most foods need batter coatings for protection, it is not as necessary for cooked noodles and potatoes because their high starch content enables them to hold more moisture and resist shrinking. Meats may be cooked before deep frying to ensure that they are done inside while keeping juiciness. When performed properly, deep frying does not make food excessively greasy, because the moisture in the food repels the oil. The hot oil heats the water within the food,

it; oil cannot go against the direction of this powerful flow because (due to its high temperature) the water vapor pushes the bubbles toward the surface. As long as the oil is hot enough and the food is not immersed in the oil for too long, oil penetration will be confined to the outer surface. Foods deep-fried at proper temperatures typically absorb "no more than a couple of tablespoons per cups of oil" used. This oil absorption rate is around the same as occurs with shallow frying, such as in a pan. However, if the food is cooked in the oil for too long, much of the water will be lost and the oil will begin to penetrate the food. The correct frying temperature depends on the thickness and type of food, but in most cases it lies between . An informal test for a temperature close to this range involves adding a tiny amount of flour into the oil and watching to see if it sizzles without immediately burning. A second test involves adding one piece of food to deep fry and watching it sink somewhat and rise back up. Sinking without resurfacing indicates that the oil is too cold; not sinking at all indicates that the oil is too hot. It is recommended that deep fryers be cleaned often to prevent contamination. The process of cooking with oil can also contaminate nearby surfaces as oil may splatter on adjacent areas. Oil vapors can also condense on more distant surfaces such as walls and ceilings. Supplies such as dish detergent and baking soda can effectively clean affected surfaces.

Oil deterioration and chemical changes

Deep fat frying involves heating oil to temperatures in excess of 180 °C in the presence of moisture and air. These conditions can induce a series of complex chemical reactions which may impact the quality of both the food and the oil it is cooked in. Examples of different chemical reactions include the production of
free radicals In chemistry, a radical, also known as a free radical, is an atom, molecule, or ion that has at least one unpaired valence electron. With some exceptions, these unpaired electrons make radicals highly chemically reactive. Many radicals spont ...

, and fires may be caused by it igniting at too high a temperature. Further, attempts to extinguish an oil fire with water can cause an extremely dangerous condition, a boilover, as they cause the water to flash into steam due to the high heat of the oil, in turn sending the burning oil in all directions and thus aggravating the fire. This is the leading cause of house fires in the United Kingdom. Instead, oil fires must be extinguished with a non-water

s, In the worst-case scenario, severe burns can be fatal. The higher temperatures and tendency of oil to stick to the skin make spilled hot cooking oil far more dangerous than spilled hot water. Children can accidentally place their hands on top of the stove, playing with the materials while being cooked, or accidentally pull the pot down, which can cause significant injury. If children are present, the utmost care should be used when deep frying so that their safety can be protected at all times.

. The heating element in a deep fryer consumes enormous energy, electricity or otherwise. According to one source, an average home appliance deep fryer draws 2,000 watts. Potatoes that are stored in artificially humidified warehouses contain more water, which makes the time required to deep fry them into chips longer. This increases the carbon dioxide footprint of commercially producing chips because more energy is required for frying over a longer time.


Health

The process of deep frying food is generally detrimental to its nutritional value. The oils that foods absorb in their batter typically contain large amounts of

categorizes the idea that burnt food causes cancer as a "myth". Additionally, fat degradation processes ( lipid peroxidation) during deep frying results in the loss of nutritional value in deep-fried foods. Cooking oil that has been used for too long may in addition cause blood pressure elevation and vascular hypertrophy. Trans fats are used in shortenings for deep-frying in restaurants, as they can be used for longer than most conventional oils before becoming rancid. In the early 21st century, non-hydrogenated vegetable oils that have lifespans exceeding that of the frying shortenings became available. As fast-food chains routinely use different fats in different locations, trans fat levels in fast food can have large variations. The amount of trans fat that is formed during frying appears to increase with frying temperature, frying time, oil oxidation, and oil reuse. Some studies have found that deep frying in olive and sunflower oils has been found to be less of a detriment to health and in some cases have positive effects on

levels. Oil can be reused a few times after original use after straining out solids. However, excessive use of the same oil can cause it to break down and release compounds into the food that may be carcinogenic, affect liver health, or influence the body's ability to absorb vitamins. Some European countries have set public health standards for the safety of frying oil.
