Fermented Tea
Fermented tea (also known as post-fermented tea or dark tea) is a class of tea that has undergone microbial fermentation (biochemistry), fermentation, from several months to many years. The exposure of the tea leaves to humidity and oxygen during the process also causes endo-oxidation (derived from the tea-leaf enzymes themselves) and exo-oxidation (which is microbe, microbially catalysed). The tea leaves and the liquor made from them become darker with oxidation. Thus, the various kinds of fermented teas produced across China are also referred to as dark tea, not be confused with black tea, which is actually referred to as "red tea" (''hong cha'', wikt:红茶, 红茶) in Chinese. The most famous fermented tea is produced in Yunnan, Yunnan province. The fermentation of tea leaves alters their chemistry, affecting the organoleptic qualities of the tea made from them. Fermentation affects the odor, smell of the tea and typically mellows its taste, reducing astringency and bitter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pu'er Tea
''Pu'er'' or ''pu-erh'' is a variety of fermented tea traditionally produced in Yunnan Province, China. Pu- erh tea is made from the leaves of the Yunnan tea plant ''Camellia sinensis var. assamica'', which is a specific variety of tea plant that is native to Yunnan Province. It differs from Yunnan tea (Dianhong) in that pu-erh tea goes through a complex fermentation process. In the context of traditional Chinese tea production terminology, fermentation refers to microbial fermentation (called 'wet piling'), and is typically applied after the tea leaves have been sufficiently dried and rolled. As the tea undergoes controlled microbial fermentation, it also continues to oxidize, which is also controlled, until the desired flavors are reached. This process produces tea known as ''hēichá'' (黑茶), literally "black tea", though the term is commonly translated to English as "dark tea" to distinguish it from the English-language "black tea" (紅茶 ''hóngchá'', lit. "red tea" in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperature Gradient Gel Electrophoresis
Temperature gradient gel electrophoresis (TGGE) and denaturing gradient gel electrophoresis (DGGE) are forms of electrophoresis which use either a temperature or chemical gradient to denature the sample as it moves across an acrylamide gel. TGGE and DGGE can be applied to nucleic acids such as DNA and RNA, and (less commonly) proteins. TGGE relies on temperature dependent changes in structure to separate nucleic acids. DGGE separates genes of the same size based on their different denaturing ability which is determined by their base pair sequence. DGGE was the original technique, and TGGE a refinement of it. History DGGE was invented by Leonard Lerman, while he was a professor at SUNY Albany. The same equipment can be used for analysis of protein, which was first done by Thomas E. Creighton of the MRC Laboratory of Molecular Biology, Cambridge, England. Similar looking patterns are produced by proteins and nucleic acids, but the fundamental principles are quite different.

Ming Dynasty
The Ming dynasty, officially the Great Ming, was an Dynasties of China, imperial dynasty of China that ruled from 1368 to 1644, following the collapse of the Mongol Empire, Mongol-led Yuan dynasty. The Ming was the last imperial dynasty of China ruled by the Han people, the majority ethnic group in China. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng (who established the short-lived Shun dynasty), numerous rump state, rump regimes ruled by remnants of the House of Zhu, Ming imperial family, collectively called the Southern Ming, survived until 1662. The Ming dynasty's founder, the Hongwu Emperor (1368–1398), attempted to create a society of self-sufficient rural communities ordered in a rigid, immobile system that would guarantee and support a permanent class of soldiers for his dynasty: the empire's standing army exceeded one million troops and the naval history of China, navy's dockyards in Nanjing were the largest in the world.

Dysentery
Dysentery ( , ), historically known as the bloody flux, is a type of gastroenteritis that results in bloody diarrhea. Other symptoms may include fever, abdominal pain, and a feeling of incomplete defecation. Complications may include dehydration. The cause of dysentery is usually the bacteria from genus '' Shigella'', in which case it is known as shigellosis, or the amoeba '' Entamoeba histolytica''; then it is called amoebiasis. Other causes may include certain chemicals, other bacteria, other protozoa, or parasitic worms. It may spread between people. Risk factors include contamination of food and water with feces due to poor sanitation. The underlying mechanism involves inflammation of the intestine, especially of the colon. Efforts to prevent dysentery include hand washing and food safety measures while traveling in countries of high risk. While the condition generally resolves on its own within a week, drinking sufficient fluids such as oral rehydration solutio ...

Ancient Tea Route
The Tea Horse Road or ''Chamadao'' (), now generally referred to as the Ancient Tea Horse Road or ''Chamagudao'' () was a network of caravan paths winding through the mountains of Sichuan, Yunnan and Tibet in Southwest China. This was also a tea trade route. It is also sometimes referred to as the "Southern Silk Road" or "Southwest Silk Road." There are numerous surviving archaeological and monumental elements, including trails, bridges, way stations, market towns, palaces, staging posts, shrines and temples along the route. "Ancient Tea Horse Road" is a historical concept with a specific meaning. It refers to a major traffic road formed by the exchange of tea and horses between Han and Tibet from the Tang and Song Dynasties to the Republic of China.

Silk Road
The Silk Road was a network of Asian trade routes active from the second century BCE until the mid-15th century. Spanning over , it played a central role in facilitating economic, cultural, political, and religious interactions between the Eastern world, Eastern and Western worlds. The name "Silk Road" was coined in the late 19th century, but some 20th- and 21st-century historians instead prefer the term Silk Routes, on the grounds that it more accurately describes the intricate web of land and sea routes connecting Central Asia, Central, East Asia, East, South Asia, South, Southeast Asia, Southeast, and West Asia as well as East Africa and Southern Europe. The Silk Road derives its name from the highly lucrative trade of silk textiles that were History of Silk, primarily produced in China. The network began with the expansion of the Han dynasty (202 BCE220 CE) into Central Asia around 114 BCE, through the missions and explorations of the Chinese imperial env ...

Lahpet
Lahpet, also spelled laphet, laphat, lephet, leppet, or letpet in English (, ), is Burmese for fermented or pickled tea. Myanmar is one of the few countries where tea is consumed both as a drink and as an eaten delicacy, in the form of pickled tea, which is unique to this region. Lahpet is regarded as a national delicacy that plays a significant role in Burmese society, and remains a traditional Burmese gesture of hospitality and is served to guests visiting a home. Its place in the cuisine of Myanmar is reflected by the following popular expression: "Of all the fruit, the mango's the best; of all the meat, pork's the best; and of all the leaves, lahpet's the best". In English-speaking areas, laphet is most commonly encountered in "tea leaf salad" (). Fermented or pickled tea is featured in the cuisines of many ethnicities who live near the geographical origin of tea, such as the cuisines of the Bulang, and in Tai cuisine (where it is known as ''miang'' in dishes such as ...
