Decaffeinated
Decaffeination is the removal of caffeine from coffee beans, cocoa, tea leaves, and other caffeine-containing materials. Decaffeinated products are commonly termed by the abbreviation decaf. To ensure product quality, manufacturers are required to test the newly decaffeinated coffee beans to make sure that caffeine concentration is relatively low. A caffeine content reduction of at least 97% is required under United States FDA standards. A 2006 study found decaffeinated drinks to contain typically 1–2% of the original caffeine content, but sometimes as much as 20%. Decaffeinated coffee Friedlieb Ferdinand Runge performed the first isolation of caffeine from coffee beans in 1820, after the German poet Goethe heard about his work on belladonna extract, and requested he perform an analysis on coffee beans. Though Runge was able to isolate the compound, he did not learn much about the chemistry of caffeine itself, nor did he seek to use the process commercially to produce deca ...

Caffeine
Caffeine is a central nervous system (CNS) stimulant of the methylxanthine chemical classification, class and is the most commonly consumed Psychoactive drug, psychoactive substance globally. It is mainly used for its eugeroic (wakefulness promoting), ergogenic (physical performance-enhancing), or nootropic (cognitive-enhancing) properties. Caffeine acts by blocking the binding of adenosine at a number of adenosine receptor types, inhibiting the centrally depressant effects of adenosine and enhancing the release of acetylcholine. Caffeine has a three-dimensional structure similar to that of adenosine, which allows it to bind and block its receptors. Caffeine also increases Cyclic adenosine monophosphate, cyclic AMP levels through nonselective Phosphodiesterase inhibitor, inhibition of phosphodiesterase, increases calcium release from intracellular stores, and Receptor antagonist, antagonizes GABA receptor, GABA receptors, although these mechanisms typically occur at concentrati ...

Sanka
Sanka is a brand of instant decaffeinated coffee, sold around the world, and was one of the earliest decaffeinated varieties. Sanka is distributed in the United States by Kraft Heinz. History Decaffeinated coffee was developed in 1903 (see Decaffeination: Roselius process) by a team of researchers led by Ludwig Roselius in Bremen, Germany. It was first sold in Germany and many other European countries in 1905–1906 under the name Kaffee HAG (short for ''Kaffee Handels- Aktien-Gesellschaft'', or Coffee Trading Public Company).100 Jahre Kaffee Hag (100 years Coffee Hag), issued by Kraft Foods Germany, 2006, . In France, the brand name became ''Sanka'', derived from the French words ''sans caféine'' ("without caffeine"). The brand came to the United States in 1909–1910, where it was first marketed under the name "Dekafa" or "Dekofa" by an American sales agent. In 1914, Roselius founded his own company, Kaffee Hag Corporation, in New York. When Kaffee Hag was confiscated by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Café HAG
Café HAG is a worldwide brand of Decaffeination, decaffeinated coffee currently owned by JDE Peet's. History Café HAG was founded in Bremen in 1906 as ''Kaffee-Handels-Aktiengesellschaft'' (Coffee Trading Limited). The company's founder was Ludwig Roselius, who codeveloped the first commercial decaffeination process. Alfred Runge and Eduard Scotland designed posters and packaging, and are credited with designs that defined the company. In the 1920s and 1930s the company was known for the publication of the Coffee Hag albums, Café HAG albums of heraldic emblems. The coffee brand Sanka spun off from Café HAG in 1910 for the French market ("Sanka" is a contraction of ''sans caféine''), and American rights to the Sanka name were sold in 1913. The Kellogg Company purchased Roselius's American branch (based in Cleveland, Ohio) in 1928, then sold it to General Foods in 1939. General Foods acquired the original German company in 1979. In 1990 Kraft Foods merged with General Fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ludwig Roselius
Ludwig Roselius (2 June 1874 – 15 May 1943) was a German coffee merchant and founder of the company Kaffee HAG. He was born in Bremen and is credited with the development of commercial decaffeination of coffee. As a patron, he supported artists like Paula Modersohn-Becker and Bernard Hoetger and turned the Böttcherstrasse street in Bremen into an artwork. Life Roselius was born in Bremen. In 1902, Ludwig Roselius purchased the centrally located No. 4 Böttcherstrasse. It soon became the head office of his business Roselius & Co. which in 1906 established Kaffee HAG (Kaffee Handels Aktien Gesellschaft). He was a supporter of ''Die Brücke'' institute and started publication of the famous heraldic Coffee Hag albums in the described formats of the Brücke. In his home town he built an entertaining house known as the Glockenspiel House. During the Third Reich, "Politically a conservative, Roselius had a positive attitude towards National Socialism and initially suppo ...

Coffee is a beverage brewed from roasted, ground coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulating effect on humans, primarily due to its caffeine content, but decaffeinated coffee is also commercially available. There are also various coffee substitutes. Typically served hot, coffee has the highest sales in the world market for hot drinks. Coffee production begins when the seeds from coffee cherries (the ''Coffea'' plant's fruits) are separated to produce unroasted green coffee beans. The "beans" are roasted and then ground into fine particles. Coffee is brewed from the ground roasted beans, which are typically steeped in hot water before being filtered out. It is usually served hot, although chilled or iced coffee is common. Coffee can be prepared and presented in a variety of ways (e.g., espresso, French press, caffè latte, or already-brewed canned coffee). Sugar, sugar substitutes, milk, and cream are often added to mask the bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cocoa Bean
The cocoa bean, also known as cocoa () or cacao (), is the dried and fully fermented seed of ''Theobroma cacao'', the cacao tree, from which cocoa solids (a mixture of nonfat substances) and cocoa butter (the fat) can be extracted. Cacao trees are native to the Amazon rainforest. They are the basis of chocolate and Mesoamerican foods including tejate, an indigenous Mexican drink. The cacao tree was first domesticated at least 5,300 years ago by the Mayo-Chinchipe culture in South America before it was introduced in Mesoamerica. Cacao was consumed by pre-Hispanic cultures in spiritual ceremonies, and its beans were a common currency in Mesoamerica. The cacao tree grows in a limited geographical zone; today, West Africa produces nearly 81% of the world's crop. The three main varieties of cocoa plants are Forastero, Criollo, and Trinitario, with Forastero being the most widely used. In 2024, global cocoa bean production reached 5.8 million tonnes, with Ivory Coast leading a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmosphere (unit)
The standard atmosphere (symbol: atm) is a unit of pressure defined as Pa. It is sometimes used as a ''reference pressure'' or ''standard pressure''. It is approximately equal to Earth's average atmospheric pressure at sea level. History The standard atmosphere was originally defined as the pressure exerted by a 760 mm column of mercury at and standard gravity (''g''n = ). It was used as a reference condition for physical and chemical properties, and the definition of the centigrade temperature scale set 100 °C as the boiling point of water at this pressure. In 1954, the 10th General Conference on Weights and Measures (CGPM) adopted ''standard atmosphere'' for general use and affirmed its definition of being precisely equal to dynes per square centimetre (). This defined pressure in a way that is independent of the properties of any particular substance. In addition, the CGPM noted that there had been some misapprehension that the previous definition (from the 9th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Critical Point (thermodynamics)
In thermodynamics, a critical point (or critical state) is the end point of a phase Equilibrium (thermodynamics), equilibrium curve. One example is the liquid–vapor critical point, the end point of the pressure–temperature curve that designates conditions under which a liquid and its vapor can coexist. At higher temperatures, the gas comes into a supercritical fluid, supercritical phase, and so cannot be liquefied by pressure alone. At the critical point, defined by a ''critical temperature'' ''T''c and a ''critical pressure'' ''p''c, phase (matter), phase boundaries vanish. Other examples include the Upper critical solution temperature, liquid–liquid critical points in mixtures, and the ferromagnet–paramagnet transition (Curie temperature) in the absence of an external magnetic field. Liquid–vapor critical point Overview For simplicity and clarity, the generic notion of ''critical point'' is best introduced by discussing a specific example, the vapor–liquid cr ...

Triglycerides
A triglyceride (from ''wikt:tri-#Prefix, tri-'' and ''glyceride''; also TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids. Triglycerides are the main constituents of body fat in humans and other vertebrates as well as vegetable fat. They are also present in the blood to enable the bidirectional transference of Adipose tissue, adipose fat and blood glucose from the liver and are a major component of sebum, human skin oils. Many types of triglycerides exist. One specific classification focuses on Saturated and unsaturated compounds, saturated and unsaturated types. Saturated fats have ''no'' C=C groups; unsaturated fats feature one or more C=C groups. Unsaturated fats tend to have a lower melting point than saturated analogues; as a result, they are often liquid at room temperature. Chemical structure The three fatty acids substituents can be the same, but they are usually different. The positions of the three fatty acids a ...

Activated Carbon
Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, low-volume pores that greatly increase the surface area available for ''adsorption '' or chemical reactions. (Adsorption, not to be confused with Absorption (chemistry), absorption, is a process where atoms or molecules adhere to a surface). The pores can be thought of as a microscopic "sponge" structure. Activation is analogous to making popcorn from dried corn kernels: popcorn is light, fluffy, and its kernels have a high surface-area-to-volume ratio. ''Activated'' is sometimes replaced by ''active''. Because it is so porous on a microscopic scale, one gram of activated carbon has a surface area of over , as determined by gas absorption and its porosity can run 10ML/day in terms of treated water per gram. Researchers at Cornell University synthesized an ultrahigh surface area activated ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
