Cooking
Cooking, cookery, or culinary arts is the art, science and craft of using heat to prepare food for consumption. 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. Types of cooking also depend on the skill levels and training of the cooks. 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 the invention of pottery for holding and boiling of water, expanded cooking ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trans Fat
Trans fat, also called trans-unsaturated fatty acids, or trans fatty acids, is a type of unsaturated fat that naturally occurs in small amounts in meat and milk fat. It became widely produced as an unintentional byproduct in the industrial processing of vegetable and fish oils in the early 20th century for use in margarine and later also in snack food, packaged baked goods, and for frying fast food. In nature, unsaturated fatty acids generally have ''cis'' configurations as opposed to ''trans'' configurations. While saturated fatty acids without any double bonds are created from unsaturated fats by the process of fat hydrogenation, partial hydrogenation converts some of the ''cis'' double bonds into ''trans'' double bonds by an isomerization reaction with the catalyst used for the hydrogenation, which yields a trans fat. In food production, liquid cis-unsaturated fats such as vegetable oils are hydrogenated to produce saturated fats, which have more desirable physical prope ...

Shortening
Shortening is any fat that is a solid at room temperature and used to make crumbly pastry and other food products. Although butter is solid at room temperature and is frequently used in making pastry, the term ''shortening'' seldom refers to butter. The idea of shortening dates back to at least the 18th century, well before the invention of modern, shelf-stable vegetable shortening. In the earlier centuries, lard was the primary ingredient used to shorten dough. The reason it is called shortening is that it makes the resulting food crumbly, or to behave as if it has short fibers. Solid fat prevents cross-linkage between gluten molecules. This cross-linking would give dough elasticity, so it could be stretched into longer pieces. In pastries such as cake, which should not be elastic, shortening is used to produce the desired texture. History and market Originally shortening was synonymous with lard, but with the invention of margarine from beef tallow by French chemist H ...

Rendering (animal Products)
Rendering is a process that converts waste animal tissue into stable, usable materials. Rendering can refer to any processing of animal products into more useful materials, or, more narrowly, to the rendering of whole animal fatty tissue into purified fats like lard or tallow. Rendering can be carried out on an industrial, farm, or kitchen scale. It can also be applied to non-animal products that are rendered down to pulp. In animal products, the majority of tissue processed comes from slaughterhouses, with the most common animal sources are beef, pork, mutton, and poultry. The rendering process simultaneously dries the material and separates the fat from the bone and protein, yielding a fat commodity and a protein meal. The occupation of renderer has been described as dangerous and dirty. Description A rendering process converts waste animal tissue into stable, usable materials. Rendering can refer to any processing of animal products into more useful materials, or, mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vegetable Oils
Vegetable oils, or vegetable fats, are oils extracted from seeds or from other parts of fruits. Like animal fats, vegetable fats are ''mixtures'' of triglycerides. Soybean oil, grape seed oil, and cocoa butter are examples of seed oils, or fats from seeds. Olive oil, palm oil, and rice bran oil are examples of fats from other parts of fruits. In common usage, vegetable ''oil'' may refer exclusively to vegetable fats which are liquid at room temperature. Vegetable oils are usually edible. Uses In antiquity Oils extracted from plants have been used since ancient times and in many cultures. Archaeological evidence shows that olives were turned into olive oil by 6000 BCE and 4500 BCE in present-day Israel and Palestine. In addition to use as food, fats and oils (both vegetable and mineral) have long been used as fuel, typically in lamps which were a principal source of illumination in ancient times. Oils may have been used for lubrication, but there is no evidence for this. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pastry
Pastry is baked food made with a dough of flour, water and shortening (solid fats, including butter or lard) that may be savoury or sweetened. Sweetened pastries are often described as '' bakers' confectionery''. The word "pastries" suggests many kinds of baked products made from ingredients such as flour, sugar, milk, butter, shortening, baking powder, and eggs. Small tarts and other sweet baked products are called pastries as a synecdoche. Common pastry dishes include pies, tarts, quiches, croissants, and pasties. The French word pâtisserie is also used in English (with or without the accent) for the same foods. Originally, the French word referred to anything, such as a meat pie, made in dough (''paste'', later ''pâte'') and not typically a luxurious or sweet product. This meaning still persisted in the nineteenth century, though by then the term more often referred to the sweet and often ornate confections implied today. Pastry can also refer to the pastry ...

Pork
Pork is the culinary name for the meat of the domestic pig (''Sus domesticus''). It is the most commonly consumed meat worldwide, with evidence of pig husbandry dating back to 5000 BCE. Pork is eaten both freshly cooked and preserved; curing extends the shelf life of pork products. Ham, gammon, bacon, and sausage are examples of preserved pork. Charcuterie is the branch of cooking devoted to prepared meat products, many from pork. Pork is the most popular meat in the Western world, particularly in Central Europe. It is also very popular in East and Southeast Asia ( Mainland Southeast Asia, Philippines, Singapore, and East Timor). The meat is highly prized in Asian cuisines, especially in Mainland China, for its fat content and texture. Some religions and cultures prohibit pork consumption, notably Islam and Judaism. History Pigs were domesticated in Mesopotamia around 13,000 BC. Charcuterie is the branch of cooking devoted to prepared meat products su ...

Tallow
Tallow is a rendered form of beef or mutton fat, primarily made up of triglycerides. In industry, tallow is not strictly defined as beef or mutton fat. In this context, tallow is animal fat that conforms to certain technical criteria, including its melting point. Commercial tallow commonly contains fat derived from other animals, such as lard from pigs, or even from plant sources. The adjacent diagram shows the chemical structure of a typical triglyceride molecule. The solid material remaining after rendering is called cracklings, greaves, or graves. It has been used mostly for animal food, such as dog food. In the soap industry and among soap-making hobbyists, the name tallowate is used informally to refer to soaps made from tallow. Sodium tallowate, for example, is obtained by reacting tallow with sodium hydroxide (lye, caustic soda) or sodium carbonate (washing soda). It consists chiefly of a variable mixture of sodium salts of fatty acids, such as oleic and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oleic Acid
Oleic acid is a fatty acid that occurs naturally in various animal and vegetable fats and oils. It is an odorless, colorless oil, although commercial samples may be yellowish. In chemical terms, oleic acid is classified as a monounsaturated omega-9 fatty acid, abbreviated with a lipid number of 18:1 ''cis''-9, and a main product of Δ9 desaturase. It has the formula CH3(CH2)7CH=CH(CH2)7COOH. The name derives from the Latin word ''oleum'', which means oil. It is the most common fatty acid in nature. The salts and esters of oleic acid are called oleates. Occurrence Fatty acids (or their salts) often do not occur as such in biological systems. Instead fatty acids such as oleic acid occur as their esters, commonly triglycerides, which are the greasy materials in many natural oils. Oleic acid is the most common monounsaturated fatty acid in nature. It is found in fats (triglycerides), the phospholipids that make membranes, cholesterol esters, and wax esters. Triglycerides ...

Sausage
A sausage is a type of meat product usually made from ground meat—often pork, beef, or poultry—along with salt, spices and other flavourings. Other ingredients, such as grains or breadcrumbs may be included as fillers or extenders. When used as an adjective, the word ''sausage'' can refer to the loose sausage meat, which can be formed into patties or stuffed into a skin. When referred to as "a sausage", the product is usually cylindrical and encased in a skin. Typically, a sausage is formed in a casing traditionally made from intestine, but sometimes from synthetic materials. Sausages that are sold raw are cooked in many ways, including pan-frying, broiling and barbecuing. Some sausages are cooked during processing, and the casing may then be removed. Sausage-making is a traditional food preservation technique. Sausages may be preserved by curing, drying (often in association with fermentation or culturing, which can contribute to preservation), smoking, ...

Cattle
Cattle (''Bos taurus'') are large, domesticated, cloven-hooved, herbivores. They are a prominent modern member of the subfamily Bovinae and the most widespread species of the genus '' Bos''. Adult females are referred to as cows and adult males are referred to as bulls. Cattle are commonly raised as livestock for meat (beef or veal, see beef cattle), for milk (see dairy cattle), and for hides, which are used to make leather. They are used as riding animals and draft animals ( oxen or bullocks, which pull carts, plows and other implements). Another product of cattle is their dung, which can be used to create manure or fuel. In some regions, such as parts of India, cattle have significant religious significance. Cattle, mostly small breeds such as the Miniature Zebu, are also kept as pets. Different types of cattle are common to different geographic areas. Taurine cattle are found primarily in Europe and temperate areas of Asia, the Americas, and Australia. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
