Crush, Tear, Curl
Crush, tear, curl (sometimes cut, tear, curl) is a method of processing tea leaves into black tea in which the leaves are passed through a series of cylindrical rollers with hundreds of sharp teeth that crush, tear, and curl the tea into small, hard pellets. This replaces the final stage of orthodox tea manufacture, in which the leaves are rolled into strips. Tea produced using this method is generally called CTC tea or mamri tea. History The first CTC machine was brought into service in 1930 at the Amgoorie Tea Garden in Assam under the supervision of Sir William McKercher. It proliferated over three decades starting in 1950, most rapidly in India and Africa. Production Today, most black teas produced use the CTC method or the closely related Rotorvane orthodox manufacture. CTC and Rotorvane orthodox have a finished product that is well suited for tea bags, as the product quickly gives a dark brew. For many large tea producers, 80% to 90% of the factory's production is of sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tea Processing
Tea processing is the method in which the leaves from the tea plant ''Camellia sinensis'' are transformed into the dried leaves for brewing tea. The categories of tea are distinguished by the processing they undergo. In its most general form, tea processing involves different manners and degrees of oxidation of the leaves, stopping the oxidation, forming the tea and drying it. The innate flavor of the dried tea leaves is determined by the type of cultivar of the tea bush, the quality of the plucked tea leaves, and the manner and quality of the production processing they undergo. After processing, a tea may be blended with other teas or mixed with flavourants to alter the flavor of the final tea. When producing black, pu'erh and oolong teas there is an additional purpose of processing: to encourage oxidization, which further develops flavour and aroma compounds. History The history of tea processing corresponds intimately with the role that tea played in Chinese society and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commonwealth Of Independent States
The Commonwealth of Independent States (CIS) is a regional organization, regional intergovernmental organization in Eurasia. It was formed following the dissolution of the Soviet Union, dissolution of the Soviet Union in 1991. It covers an area of and has an estimated population of 246,200,194. The CIS encourages cooperation in economic, political, and military affairs and has certain powers relating to the coordination of trade, finance, lawmaking, and security, including cross-border crime prevention. As the Soviet Union disintegrated, Byelorussian SSR, Belarus, Russian SFSR, Russia, and Ukrainian SSR, Ukraine signed the Belovezha Accords on 8 December 1991, declaring that the Union had effectively ceased to exist and proclaimed the CIS in its place. On 21 December, the Alma-Ata Protocol was signed, but Estonia, Latvia and Lithuania chose not to participate. Georgia (country), Georgia withdrew its membership in 2008 following Russo-Georgian War, a war with Russia. Ukraine f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assam Tea
Assam tea is a black tea named after Assam, India, the region of its production. It is manufactured specifically from the plant ''Camellia sinensis'' var. ''assamica'' (Masters). Assam's people tried to plant the Chinese varieties in Assam soil but did not succeed. Assam tea is now mostly grown at or near sea level and is known for its body, briskness, malty flavour, and strong, bright colour. Assam teas, or blends containing Assam tea, are often sold as "breakfast" teas. For instance, Irish breakfast tea, a maltier and stronger breakfast tea, consists of small-sized Assam tea leaves. The state of Assam is the world's largest tea-growing region by production, lying on either side of the Brahmaputra River, and bordering Bhutan, Bangladesh, Myanmar and very close to China. This part of India experiences high rainfall; during the monsoon period, as much as 250 to 300 mm (10 to 12 in) of rain falls per day. The daytime temperature rises to about 36 °C (96.8 °F), c ...

Mahogany
Mahogany is a straight- grained, reddish-brown timber of three tropical hardwood species of the genus ''Swietenia'', indigenous to the AmericasBridgewater, Samuel (2012). ''A Natural History of Belize: Inside the Maya Forest''. Austin: University of Texas Press. pp. 164–165. . and part of the pantropical chinaberry family, Meliaceae. Mahogany is used commercially for a wide variety of goods, due to its coloring and durable nature. It is naturally found within the Americas, but has also been imported to plantations across Asia and Oceania. The mahogany trade is believed to have started as early as the 16th century and flourished throughout the 17th and 18th centuries. In some countries, mahogany is classified as an invasive species. Mahogany is wood from any of three tree species: Honduran or big-leaf mahogany ('' Swietenia macrophylla''), West Indian or Cuban mahogany ('' Swietenia mahagoni''), and '' Swietenia humilis''. Honduran mahogany is the most widespread and the only g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxidise
Redox ( , , reduction–oxidation or oxidation–reduction) is a type of chemical reaction in which the oxidation states of the reactants change. Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. The oxidation and reduction processes occur simultaneously in the chemical reaction. There are two classes of redox reactions: * Electron-transfer – Only one (usually) electron flows from the atom, ion, or molecule being oxidized to the atom, ion, or molecule that is reduced. This type of redox reaction is often discussed in terms of redox couples and electrode potentials. * Atom transfer – An atom transfers from one substrate to another. For example, in the rusting of iron, the oxidation state of iron atoms increases as the iron converts to an oxide, and simultaneously, the oxidation state of oxygen decreases as it accepts electrons released by the iron. Although oxidati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytin
Phytic acid is a six-fold dihydrogenphosphate ester of inositol (specifically, of the ''myo'' isomer), also called inositol hexaphosphate, inositol hexakisphosphate (IP6) or inositol polyphosphate. At physiological pH, the phosphates are partially ionized, resulting in the phytate anion. The (''myo'') phytate anion is a colorless species that has significant nutritional role as the principal storage form of phosphorus in many plant tissues, especially bran and seeds. It is also present in many legumes, cereals, and grains. Phytic acid and phytate have a strong binding affinity to the dietary minerals calcium, iron, and zinc, inhibiting their absorption in the small intestine. The lower inositol polyphosphates are inositol esters with less than six phosphates, such as inositol penta- (IP5), tetra- (IP4), and triphosphate ( IP3). These occur in nature as catabolites of phytic acid. Significance in agriculture Phytic acid was discovered in 1903. Generally, phosphorus and inos ...

The Middle East
The Middle East (term originally coined in English language) is a geopolitical region encompassing the Arabian Peninsula, the Levant, Turkey, Egypt, Iran, and Iraq. The term came into widespread usage by the United Kingdom and western European nations in the early 20th century as a replacement of the term Near East (both were in contrast to the Far East). The term "Middle East" has led to some confusion over its changing definitions. Since the late 20th century, it has been criticized as being too Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of West Asia, but without the South Caucasus. It also includes all of Egypt (not just the Sinai) and all of Turkey (including East Thrace). Most Middle Eastern countries (13 out of 18) are part of the Arab world. The most populous countries in the region are Egypt, Turkey, and Iran, while Saudi Arabia is the largest Middle Eastern country by area. The history of ...

Indian Tea
India is the second largest producer of tea in the world after China, including the famous Assam tea and Darjeeling tea. Tea is the 'State Drink' of Assam. Following this the former Planning Commission (renamed Niti Aayog) Deputy Chairman, Montek Singh Ahluwalia had plans to officially recognise tea as the Indian "National Drink" in 2013. According to the ASSOCHAM report released in December 2011, India is the world's largest consumer of tea, consuming nearly 30% of global output. India is also the second-largest exporter of tea, after China. The practice of Ayurveda has resulted in a long-standing tradition of herbal teas. Traditional Indian kitchens have long utilised the medicinal benefits offered by various plants and spices such as holy basil (Tulsi), cardamom (Elaichi), Black pepper, pepper (Kali Mirch), liquorice (Mulethi), Mentha, mint (Pudina), etc., and traditionally, teas made with these plant leaves or spices have been in use for centuries for maladies ranging fr ...

Black Tea
Black tea (also literally translated as red tea from various East Asian languages) is a type of tea that is more tea processing, oxidized than oolong, yellow tea, yellow, white tea, white, and green tea, green teas. Black tea is generally stronger in flavour than other teas. All five types are made from leaves of the shrub (or small tree) ''Camellia sinensis,'' though ''Camellia taliensis'' is also rarely used. Two principal varieties of the species are used – the small-leaved Chinese variety plant (''C. sinensis'' var. ''sinensis''), used for most other types of teas, and the large-leaved Assamese plant (''C. sinensis'' var. ''assamica''), which was traditionally mainly used for black tea, although in recent years some green and white teas have been produced. First originating in China, the beverage's name there is ''hong cha'' (, "red tea") due to the colour of the oxidized leaves when processed appropriately. Today, the drink is widespread throughout East Asi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
