It is different for
1680-750: 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. Deep frying

Cooking is done both by people in their own dwellings and by professional cooks and chefs in restaurants and other food establishments. Preparing food with heat or fire is an activity unique to humans . Archeological evidence of cooking fires from at least 300,000 years ago exists, but some estimate that humans started cooking up to 2 million years ago. The expansion of agriculture , commerce , trade , and transportation between civilizations in different regions offered cooks many new ingredients. New inventions and technologies, such as
2520-510: Is classified as a hot-fat cooking method. Typically, deep frying foods cook quickly since oil has a high rate of heat conduction and all sides of the food are cooked simultaneously. 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

4620-694: The development of many modern deep-fried dishes. Doughnuts were invented in the mid-18th century, with foods such as onion rings , deep-fried turkey , and corn dogs all being invented in the early 20th century. In recent years, the growth of fast food has expanded the reach of deep-fried foods, especially french fries. Deep frying food is defined as a process where food is submerged in hot oil at temperatures typically between 350 °F (177 °C) and 375 °F (191 °C), 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

In Asian cooking, a similar effect is obtained from a mixture of rice or corn starch and water. These techniques rely on the properties of starches to create simpler mucilaginous saccharides during cooking, which causes the familiar thickening of sauces . This thickening will break down, however, under additional heat. Types of fat include vegetable oils , animal products such as butter and lard , as well as fats from grains, including maize and flax oils. Fats are used in

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

Dietary fats are also the carriers of some flavor and aroma ingredients and vitamins that are not water-soluble . Edible animal material, including muscle , offal , milk, eggs and egg whites , contains substantial amounts of protein. Almost all vegetable matter (in particular legumes and seeds ) also includes proteins, although generally in smaller amounts. Mushrooms have high protein content. Any of these may be sources of essential amino acids . When proteins are heated they become denatured (unfolded) and change texture. In many cases, this causes

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

Some modern cooks apply advanced scientific techniques to food preparation to further enhance the flavor of the dish served. Phylogenetic analysis suggests that early hominids may have adopted cooking 1 million to 2 million years ago. Re-analysis of burnt bone fragments and plant ashes from the Wonderwerk Cave in South Africa has provided evidence supporting control of fire by early humans by 1 million years ago. In his seminal work Catching Fire: How Cooking Made Us Human , Richard Wrangham suggested that evolution of bipedalism and

The hot oil heats the water within the food, steaming 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

Cooking can prevent many foodborne illnesses that would otherwise occur if raw food is consumed. When heat is used in the preparation of food, it can kill or inactivate harmful organisms, such as bacteria and viruses, as well as various parasites such as tapeworms and Toxoplasma gondii . Food poisoning and other illness from uncooked or poorly prepared food may be caused by bacteria such as pathogenic strains of Escherichia coli , Salmonella typhimurium and Campylobacter , viruses such as noroviruses , and protozoa such as Entamoeba histolytica . Bacteria, viruses and parasites may be introduced through salad, meat that
5796-583: The practice. Deep frying is popular worldwide, with deep-fried foods accounting for a large portion of global caloric consumption. The English expression deep-fried is attested from the early 20th century. Deep-fried dough known as Zalabiyeh was eaten as early as the late 2nd millennium BC in Canaan . Frying food in olive oil is attested in Classical Greece from about the 5th century BCE. The, 5th century CE, Roman cookbook Apicius offers
5880-465: 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 , oxidation , hydrolysis , isomerization and polymerization . The exact reactions are dependent upon factors such as the oil type, frying conditions, and food being cooked. When frying, water can attack
5964-492: The present day, factory food preparation has become common, with many "ready-to-eat" as well as "ready-to-cook" foods being prepared and cooked in factories and home cooks using a mixture of scratch made , and factory made foods together to make a meal . The nutritional value of including more commercially prepared foods has been found to be inferior to home-made foods. Home-cooked meals tend to be healthier with fewer calories, and less saturated fat , cholesterol and sodium on
6048-399: The production of AGEs, as well as food rich in animal protein and fats. The production of AGEs during cooking can be significantly reduced by cooking in water or moist heat, reducing the cooking times and temperatures, as well as by first marinating the meat in acidic ingredients such as lemon juice and vinegar. The scientific study of cooking has become known as molecular gastronomy. This is
6132-775: The remaining flavor and ingredients; this is a critical component of both stewing and sauce making. Vitamins and minerals are required for normal metabolism ; and what the body cannot manufacture itself must come from external sources. Vitamins come from several sources including fresh fruit and vegetables ( Vitamin C ), carrots, liver ( Vitamin A ), cereal bran, bread, liver (B vitamins), fish liver oil ( Vitamin D ) and fresh green vegetables ( Vitamin K ). Many minerals are also essential in small quantities including iron, calcium , magnesium , sodium chloride and sulfur ; and in very small quantities copper, zinc and selenium . The micronutrients, minerals, and vitamins in fruit and vegetables may be destroyed or eluted by cooking. Vitamin C
6216-405: The risk of contamination. Proponents of raw foodism argue that cooking food increases the risk of some of the detrimental effects on food or health. They point out that during cooking of vegetables and fruit containing vitamin C , the vitamin elutes into the cooking water and becomes degraded through oxidation. Peeling vegetables can also substantially reduce the vitamin C content, especially in
6300-436: The safety of frying oil. Cooking Cooking , also known as cookery or professionally as the culinary arts , is the art, science and craft of using heat to make food more palatable , digestible , nutritious , or safe . Cooking techniques and ingredients vary widely, from grilling food over an open fire , to using electric stoves , to baking in various types of ovens , reflecting local conditions. Cooking
6384-505: The structure of the material to become softer or more friable – meat becomes cooked and is more friable and less flexible. In some cases, proteins can form more rigid structures, such as the coagulation of albumen in egg whites. The formation of a relatively rigid but flexible matrix from egg white provides an important component in baking cakes, and also underpins many desserts based on meringue . Cooking often involves water, and water-based liquids. These can be added in order to immerse
6468-538: The substances being cooked (this is typically done with water, stock or wine). Alternatively, the foods themselves can release water. A favorite method of adding flavor to dishes is to save the liquid for use in other recipes . Liquids are so important to cooking that the name of the cooking method used is often based on how the liquid is combined with the food, as in steaming , simmering , boiling , braising and blanching . Heating liquid in an open container results in rapidly increased evaporation , which concentrates
6552-490: The sugars are heated so that all water of crystallisation is driven off, caramelization starts, with the sugar undergoing thermal decomposition with the formation of carbon , and other breakdown products producing caramel . Similarly, the heating of sugars and proteins causes the Maillard reaction , a basic flavor-enhancing technique. An emulsion of starch with fat or water can, when gently heated, provide thickening to
6636-442: The time needed for the meat to be cooked at high heat. Nitrosamines are found in some food, and may be produced by some cooking processes from proteins or from nitrites used as food preservatives; cured meat such as bacon has been found to be carcinogenic, with links to colon cancer. Ascorbate , which is added to cured meat, however, reduces nitrosamine formation. Baking, grilling or broiling food, especially starchy foods, until
6720-469: 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. 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 saturated fats and trans fats . Consumption of large amounts of saturated and trans fats has been linked to
6804-442: The vulgar verb chingar ), a rude expression for the unexpected or a small insult. According to one source, Monica Flin, the founder of the Tucson, Arizona , restaurant El Charro Café (est. 1922), accidentally dropped a burrito into the deep-fat fryer in the early 1950s. She immediately began to utter a Spanish profanity beginning "chi..." ( chingada ), but quickly stopped herself and instead exclaimed chimichanga ,
6888-768: 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 class F fire extinguisher or by starving the fire of oxygen, such as can be accomplished by putting a lid back on the pan or using a fire blanket . Other means of extinguishing an oil fire include application of dry powder (e.g., baking soda , salt) or firefighting foam . Most commercial deep fryers are equipped with automatic fire suppression systems using foam. Spilled hot cooking oil can also cause severe third degree burns , In
6972-614: 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, play 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. Deep frying produces large amounts of waste oil , which must be disposed of properly. Waste oil can contribute to
7056-405: The yeast used in baking are kinds of fungi . Cooks also use water and minerals such as salt . Cooks can also use wine or spirits . Naturally occurring ingredients contain various amounts of molecules called proteins , carbohydrates and fats . They also contain water and minerals. Cooking involves a manipulation of the chemical properties of these molecules. Carbohydrates include
