Kabusecha
Kabuse tea, or is a class of Japanese tea leaf. literally means to cover or place on top, as a hat on a head, therefore kabuse tea is a tea leaf harvested from a tea plant that, for some period of time ranging from 2–25 days, has had a porous material draped over the plant while the young leaves are being produced. Kabuse tea is almost exclusively a first flush tea. Though kabuse tea is usually processed into a green tea after picking, kabuse tea denotes a pre-picking process and the freshly picked leaf can be used to produce any kind of tea, from green tea to oolong tea to black tea, or other types. Background Kabuse tea leaves are used to produce one of the three most expensive Japanese green teas (the others are gyokuro and matcha). These teas are made from leaves that are hand-plucked and grown in the shade. Shade grown leaves produce superior quality green tea - ''ooika'' is the Japanese term for the "covered aroma" of these teas, which are high in theanine and other amino ...

Sencha
is a type of Japanese ''ryokucha'' (, green tea) which is prepared by infusing the processed whole tea leaves in hot water. This is as opposed to matcha (), powdered Japanese green tea, where the green tea powder is mixed with hot water and therefore the leaf itself is included in the beverage. Sencha is the most popular tea in Japan. Overview Among the types of Japanese green tea prepared by infusion, sencha is distinguished from such specific types as gyokuro in that it is shaded for a shorter time or not at all, or bancha which is the same tea but harvested later in the season. It is the most popular tea in Japan, representing about 80 percent of the tea produced in the country. The flavour depends upon the season and place where it is produced, but shincha, or 'new tea' from the first flush of the year, is considered the most delicious. Tea-picking in Japan begins in the south, gradually moving north with the spring warmth. During the winter, tea plants store nutrients, an ...

Green Tea
Green tea is a type of tea that is made from '' Camellia sinensis'' leaves and buds that have not undergone the same withering and oxidation process which is used to make oolong teas and black teas. Green tea originated in China, and since then its production and manufacture has spread to other countries in East Asia. Several varieties of green tea exist, which differ substantially based on the variety of ''C. sinensis'' used, growing conditions, horticultural methods, production processing, and time of harvest. The two main components unique to green tea are "catechins" and "theanine," and the health effects of these components are attracting a great deal of attention in Japan and abroad. History Tea consumption has its legendary origins in China during the reign of mythological Emperor Shennong. A book written by Lu Yu in 618–907 AD (Tang dynasty), ''The Classic of Tea'' (), is considered important in green tea history. The ''Kissa Yōjōki'' (喫茶養生記 ''Book ...

Oolong Tea
Oolong (, ; (''wūlóngchá'', "dark dragon" tea)) is a traditional semi-oxidized Chinese tea (''Camellia sinensis)'' produced through a process including withering the plant under strong sun and oxidation before curling and twisting.Zhongguo Chajing pp. 222–234, 271–282, 419–412, chief editor: Chen Zhongmao, publisher: Shanghai Wenhua Chubanshe (Shanghai Cultural Publishers) 1991. Most oolong teas, especially those of fine quality, involve unique tea plant cultivars that are exclusively used for particular varieties. The degree of oxidation, which varies according to the chosen duration of time before firing, can range from 8 to 85%, depending on the variety and production style. Oolong is especially popular in south China and among ethnic Chinese in Southeast Asia as is the Fujian preparation process known as the Gongfu tea ceremony. Different styles of oolong tea can vary widely in flavor. They can be sweet and fruity with honey aromas, or woody and thick with roasted ...

Black Tea
Black tea, also translated to red tea in various East Asian languages, is a type of tea that is more oxidized than oolong, yellow, white and 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 used rarely. 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 color of the oxidized leaves when processed appropriately. Today, the drink is widespread throughout East and Southeast Asia, both in consumption and harvesting, including in China, J ...

Gyokuro
is a type of shaded green tea from Japan. It differs from the standard ''sencha'' (a classic unshaded green tea) in being grown under the shade rather than the full sun. The name "gyokuro" translates as "jewel dew" (or "jade dew"). While most sencha is from the cultivar of '' Camellia sinensis'', gyokuro is often made from a specialized variety such as Asahi, Okumidori, Yamakai, and Saemidori. Cultivation Though it is categorized as a type of sencha according to production methods, gyokuro cultivation differs from other sencha teas. Gyokuro tea leaves are shielded from the sun for at least 20 days before being harvested. This causes both the amino acid theanine and the alkaloid caffeine in the tea leaves to increase, which yields a sweet flavour. The tea also gains a distinct aroma from the covering process. Market Gyokuro is one of the most expensive types of sencha available in Japan. The name was originally the product name of the tea made by Yamamotoyama. The tea wa ...

Matcha
is finely ground powder of specially grown and processed green tea leaves, traditionally consumed in East Asia. The green tea plants used for matcha are shade-grown for three to four weeks before harvest; the stems and veins are removed during processing. During shaded growth, the plant ''Camellia sinensis'' produces more theanine and caffeine. The powdered form of matcha is consumed differently from tea leaves or tea bags, as it is suspended in a liquid, typically water or milk. The traditional Japanese tea ceremony centers on the preparation, serving and drinking of matcha as hot tea, and embodies a meditative spirituality. In modern times, matcha is also used to flavor and dye foods, such as ''mochi'' and ''soba'' noodles, green tea ice cream, matcha lattes and a variety of Japanese ''wagashi'' confectionery. Matcha used in ceremonies is referred to as ceremonial-grade, meaning that the powder is of a high enough quality to be used in the tea ceremony. Lower-quality matcha i ...

Theanine
Theanine , also known as L-γ-glutamylethylamide and ''N''5-ethyl-L-glutamine, is an amino acid analogue of the proteinogenic amino acids L-glutamate and L-glutamine and is found primarily in particular plant and fungal species. It was discovered as a constituent of green tea in 1949; in 1950, it was isolated from gyokuro leaves. Theanine provides a unique brothy or savory (umami) flavor to green tea infusions. The name "theanine" without a prefix generally implies the enantiomer L-theanine, which is the form found in tea leaves and as a dietary supplement ingredient. Most studies have used L-theanine. The opposite enantiomer, D-theanine, has been studied less. The regulatory status of theanine varies by country. In Japan, L-theanine has been approved for use in all foods, with some restrictions in the case of infant foods.Sakato,Y. J. Agri. Chem. Soc. 1949, 23, 262–267 In the United States, the Food and Drug Administration (FDA) considers it to be generally recognized ...

Amino Acid
Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although hundreds of amino acids exist in nature, by far the most important are the alpha-amino acids, which comprise proteins. Only 22 alpha amino acids appear in the genetic code. Amino acids can be classified according to the locations of the core structural functional groups, as Alpha and beta carbon, alpha- , beta- , gamma- or delta- amino acids; other categories relate to Chemical polarity, polarity, ionization, and side chain group type (aliphatic, Open-chain compound, acyclic, aromatic, containing hydroxyl or sulfur, etc.). In the form of proteins, amino acid '' residues'' form the second-largest component (water being the largest) of human muscles and other tissues. Beyond their role as residues in proteins, amino acids participate in a number of processes such as neurotransmitter transport and biosynthesis. It is thought that they played a key role in enabling life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Essential Oils
An essential oil is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compounds from plants. Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove. An essential oil is essential in the sense that it contains the essence of the plant's fragrance—the characteristic fragrance of the plant from which it is derived. The term "essential" used here does ''not'' mean indispensable or usable by the human body, as with the terms essential amino acid or essential fatty acid, which are so called because they are nutritionally required by a living organism. Essential oils are generally extracted by distillation, often by using steam. Other processes include expression, solvent extraction, '' sfumatura'', absolute oil extraction, resin tapping, wax embedding, and cold pressing. They are used in perfumes, cosmetics, soaps, air ...

Ionone
The ionones are a series of closely related chemical substances that are part of a group of compounds known as rose ketones, which also includes damascones and damascenones. Ionones are aroma compounds found in a variety of essential oils, including rose oil. β-Ionone is a significant contributor to the aroma of roses, despite its relatively low concentration, and is an important fragrance chemical used in perfumery. The ionones are derived from the degradation of carotenoids. The combination of α-ionone and β-ionone is characteristic of the scent of violets and used with other components in perfumery and flavouring to recreate their scent. The carotenes α-carotene, β-carotene, γ-carotene, and the xanthophyll Xanthophylls (originally phylloxanthins) are yellow pigments that occur widely in nature and form one of two major divisions of the carotenoid group; the other division is formed by the carotenes.
