Vegetable Oils
Vegetable oils, or vegetable fats, are oils extracted from seeds or from other parts of edible plants. 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 plants. In common usage, vegetable ''oil'' may refer exclusively to vegetable fats which are liquid at room temperature. Vegetable oils are usually edible. History In antiquity Olive oil has been a part of human culture for millennia.Ruth Schuster (December 17, 2014). "8,000-year old olive oil found in Galilee, earliest known in world", ''Haaretz''. Retrieved December 17, 2014. Archaeological evidence shows that olives were turned into olive oil by 6000 BC and 4500 BC in present-day Israel. Pagnol, p. 19, says the 6th millennium in Jericho, but cites no source. In ancient Egypt, plant oils including cedar oil, cypress oil, and ol ...

Grape Seed Oil
Grape seed oil (also called grapeseed oil or grape oil) is a vegetable oil derived from the seeds of grapes. Grape seeds are a winemaking by-product, and oil made from the seeds is commonly used as an edible oil. Description Grape seed oil has a moderately high smoke point of approximately . The oil has a light taste and a high polyunsaturated fat content, making it suitable for use in salad dressings, mayonnaise and as a base for oil infusions of garlic, rosemary, or other herbs or spices. It is widely used in baked goods, pancakes, and waffles. It is sprayed on raisins to help them retain their flavor. Uses Grapeseed oil may be used as a salad oil, massage oil, and in manufactured cosmetics or haircare products. Research A study of 21 grape cultivars showed variation of oil composition, especially for linoleic acid and tocopherols. Although grape seeds contain polyphenols, such as proanthocyanidins, grape seed oil contains negligible amounts of these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olive Oil
Olive oil is a vegetable oil obtained by pressing whole olives (the fruit of ''Olea europaea'', a traditional Tree fruit, tree crop of the Mediterranean Basin) and extracting the oil. It is commonly used in cooking for frying foods, as a condiment, or as a salad dressing. It can also be found in some cosmetics, pharmaceuticals, soaps, and fuels for traditional oil lamps. It also has additional uses in some religions. The olive is one of three core food plants in Mediterranean cuisine, with wheat and grapes. Olive trees have been cultivated around the Mediterranean since the 8th millennium BC. In 2022, Spain was the world's largest producer, manufacturing 24% of the world's total. Other large producers were Italy, Greece, and Turkey, collectively accounting for 59% of the global market. The composition of olive oil varies with the cultivar, altitude, time of harvest, and extraction process. It consists mainly of oleic acid (up to 83%), with smaller amounts of other fatty acids ...

Rice Bran Oil
Rice bran oil is the oil extracted from the hard outer brown layer of rice called bran. It is known for its high smoke point of and mild flavor, making it suitable for high-temperature cooking methods such as stir frying and deep frying. It is popular as a cooking oil in East Asia, the Indian subcontinent, and Southeast Asia including India, Nepal, Bangladesh, Indonesia, Japan, Southern China and Malaysia. Composition and properties Rice bran oil has a composition similar to that of peanut oil, with 38% monounsaturated, 37% polyunsaturated, and 25% saturated fatty acids. A component of rice bran oil is the γ-oryzanol, at around 2% of crude oil content. Thought to be a single compound when initially isolated, γ-oryzanol is now known to be a mixture of steryl and other triterpenyl esters of ferulic acids. Also present are tocopherols and tocotrienols (two types of vitamin E) and phytosterols. ;Fatty acid composition ;Physical properties of crude and refined r ...

Ginning Mill
A cotton gin—meaning "cotton engine"—is a machine that quickly and easily separates cotton fibers from their seeds, enabling much greater productivity than manual cotton separation.. Reprinted by McGraw-Hill, New York and London, 1926 (); and by Lindsay Publications, Inc., Bradley, Illinois, (). The separated seeds may be used to grow more cotton or to produce cottonseed oil. Handheld roller gins had been used in the Indian subcontinent since at earliest 500 and then in other regions. The Indian worm-gear roller gin was invented sometime around the 16th century and has, according to Lakwete, remained virtually unchanged up to the present time. A modern mechanical cotton gin was created by English-American inventor Eli Whitney in 1793 and patented in 1794. Whitney's gin used a combination of a wire screen and small wire hooks to pull the cotton through, while brushes continuously removed the loose cotton lint to prevent jams. It revolutionized the cotton industry in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crisco
Crisco is an American brand of shortening that is produced by B%26G Foods. Introduced in June 1911 by Procter & Gamble, it was the first shortening to be made entirely of vegetable oil, originally cottonseed oil. Additional products marketed under the Crisco brand include a cooking spray, various olive oils, and other cooking oils, including canola, corn, peanut, sunflower, and blended oils. History The process of the hydrogenation of organic substances in gas form was developed by Paul Sabatier in the late 19th century.

Cottonseed Oil
Cottonseed oil is cooking oil from the seeds of cotton plants of various species, mainly ''Gossypium hirsutum'' and ''Gossypium herbaceum'', that are grown for cotton fiber, animal feed, and oil. cottonseed, Cotton seed has a similar structure to other oilseeds, such as sunflower seed, having an oil-bearing Seed, kernel surrounded by a hard outer hull; in processing, the oil is extracted from the kernel. Cottonseed oil is used for salad oil, mayonnaise, salad dressing, and similar products because of its flavor stability. Composition Its fatty acid profile generally consists of 70% unsaturated fatty acids (18% monounsaturated, and 52% polyunsaturated), 26% saturated fatty acids. When it is fully Hydrogenation, hydrogenated, its profile is 94% saturated fat and 2% unsaturated fatty acids (1.5% monounsaturated, and 0.5% polyunsaturated).

Vegetable Shortening
Shortening is any fat that is a solid at room temperature and is used to make crumbly pastry and other food products. The idea of shortening dates back to at least the 18th century, well before the invention of modern, shelf-stable vegetable shortening. In 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 had short fibers. Solid fat prevents cross-linking 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 Hippolyte Mège-Mouriès in 1869, margarine also came to be included in the term. Since the invention of hydrogenated vegetable oil in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Margarine
Margarine (, also , ) is a Spread (food), spread used for flavoring, baking, and cooking. It is most often used as a substitute for butter. Although originally made from animal fats, most margarine consumed today is made from vegetable oil. The spread was originally named ''oleomargarine'' from Latin for ''oleum'' (olive oil) and Greek language, Greek ''margarite'' ("pearl", indicating luster). The name was later shortened to ''margarine'', or sometimes ''oleo'' (particularly in the Deep South). Margarine consists of a water-in-fat emulsion, with tiny droplets of water dispersed uniformly throughout a fat phase (chemistry), phase in a stable solid form. While butter is made by concentrating the butterfat of milk through centrifugation, modern margarine is made through a more intensive processing of refined vegetable oil and water. Per US federal regulation, products must have a minimum fat content of 80% (with a maximum of 16% water) to be labeled as such in the United States, ...

Trans Fat
Trans fat is a type of unsaturated fat that occurs in foods. Small amounts of trans fats occur naturally, but large amounts are found in some processed foods made with partially hydrogenated oils. Because consumption of trans fats is associated with increased risk for cardiovascular diseases, artificial trans fats are highly regulated or banned in many countries. However, they are still widely consumed in developing nations where they are associated with increased risk of diabetes, cardiovascular diseases, and death. In 2015, the US Food and Drug Administration (FDA) stated that artificial trans fats from partially hydrogenated oils were not generally recognized as safe (GRAS), and the use of such oils and trans fats should be limited or eliminated from manufactured foods. Numerous governing bodies, including the European Union, Canada, and Australia/New Zealand, followed with restrictions or bans on the use of partially hydrogenated oils and trans fats in food manufacturing. ...

Hydrogenation
Hydrogenation is a chemical reaction between molecular hydrogen (H2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to redox, reduce or Saturated and unsaturated compounds, saturate organic compounds. Hydrogenation typically constitutes the addition of pairs of hydrogen atoms to a molecule, often an alkene. Catalysts are required for the reaction to be usable; non-catalytic hydrogenation takes place only at very high temperatures. Hydrogenation reduces Double bond, double and Triple bond, triple bonds in hydrocarbons. Process Hydrogenation has three components, the Saturated and unsaturated compounds, unsaturated substrate, the hydrogen (or hydrogen source) and, invariably, a catalyst. The redox, reduction reaction is carried out at different temperatures and pressures depending upon the substrate and the activity of the catalyst. Related or competing reactions The same cataly ...
