Garucha
is a finely ground powder of green tea specially processed from shade-grown tea leaves. Shade growing gives matcha its characteristic bright green color and strong umami flavor. Matcha is typically consumed suspended in hot water. Matcha originated in China, but the production of the raw material for matcha was banned in China in the 14th century. Shade growing was invented in Japan in the 16th century and most matcha is produced there today. The traditional Japanese tea ceremony, typically known as or , centers on the preparation, serving and drinking of matcha as hot tea, and embodies a meditative and spiritual practice. 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. For this purpose, matcha made green by color additives instead of expensive shade-grown matcha is often used. Definition Strict definitions of matcha are given by the International O ...

Green Tea
Green tea is a type of tea made from the leaves and buds of the '' Camellia sinensis'' that have not undergone the withering and oxidation process that creates oolong teas and black teas. Green tea originated in China in the late 1st millennium BC, 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. While it may slightly lower blood pressure and improve alertness, current scientific evidence does not support most health benefit claims, and excessive intake of green tea extracts can cause liver damage and other side effects. 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, '' The Classic of Tea'' ( zh, t= 茶 經, s=, p=chájīng), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wagashi
is traditional Japanese confectionery, typically made using plant-based ingredients and with an emphasis on seasonality. ''Wagashi'' generally makes use of cooking methods that pre-date Western influence in Japan. It is often served with green tea. Most of today's wagashi was born during the Edo period (1603–1868). This was a period of peace, economic and cultural prosperity, and increased domestic self-sufficiency in sugar. During the Edo period, a type of wagashi called were made by kneading white bean paste, gyūhi, sugar, yams, and other ingredients, and formed into various colors and shapes based on seasonal flowers, animals, nature, events, customs, and other themes. Definition In Japan, the word for sweets or confectionery, , originally referred to fruits and nuts. Fruits and nuts may be eaten as snacks between meals and served as "sweets" during a tea ceremony. The word ''Wa'' means "Japanese", and ''kashi'' becomes ''gashi'' in compound words, ''wagashi'' there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gallic Acid
Gallic acid (also known as 3,4,5-trihydroxybenzoic acid) is a trihydroxybenzoic acid with the formula C6 H2( OH)3CO2H. It is classified as a phenolic acid. It is found in gallnuts, sumac, witch hazel, tea leaves, oak bark, and other plants. It is a white solid, although samples are typically brown owing to partial oxidation. Salts and esters of gallic acid are termed "gallates". Its name is derived from oak galls, which were historically used to prepare tannic acid. Despite the name, gallic acid does not contain gallium. Isolation and derivatives Gallic acid is easily freed from gallotannins by acidic or alkaline hydrolysis. When heated with concentrated sulfuric acid, gallic acid converts to rufigallol. Hydrolyzable tannins break down on hydrolysis to give gallic acid and glucose or ellagic acid and glucose, known as gallotannins and ellagitannins, respectively. Biosynthesis Gallic acid is formed from 3-dehydroshikimate by the action of the enzyme shikimat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Succinic Acid
Succinic acid () is a dicarboxylic acid with the chemical formula (CH2)2(CO2H)2. In living organisms, succinic acid takes the form of an anion, succinate, which has multiple biological roles as a metabolic intermediate being converted into fumarate by the enzyme succinate dehydrogenase in complex 2 of the electron transport chain which is involved in making ATP, and as a signaling molecule reflecting the cellular metabolic state. Succinate is generated in mitochondria via the tricarboxylic acid (TCA) cycle. Succinate can exit the mitochondrial matrix and function in the cytoplasm as well as the extracellular space, changing gene expression patterns, modulating epigenetic landscape or demonstrating hormone-like signaling. As such, succinate links cellular metabolism, especially ATP formation, to the regulation of cellular function. Dysregulation of succinate synthesis, and therefore ATP synthesis, happens in some genetic mitochondrial diseases, such as Leigh syndrome, and Me ...

Theanine
Theanine , also known as L-theanine, L-gamma-glutamylethylamide, or ''N''5-ethyl-L-glutamine, is a non-proteinogenic amino acid similar to the proteinogenic amino acids glutamic acid, L-glutamate and glutamine, L-glutamine. It is produced by certain plants such as the tea plant (''Camellia sinensis''), and by some fungi. Theanine was discovered in 1949 as a constituent of green tea and was isolated in 1950 from ''gyokuro'' tea leaves. It constitutes about 1–2% of the dry weight of green tea leaves. The name ''theanine'' usually refers to the enantiomer ''L-theanine'', which is the form found in tea leaves from which it is extracted as a powder. The right-handed enantiomer, ''D-theanine'', is less-studied. Theanine is sold as a dietary supplement. It is packaged in gelatin capsules, Tablet (pharmacy), tablets, and as a powder, and may be an ingredient in branded supplements with caffeine. It is also used as an ingredient in food and beverages. In 1964 Japan approved its unlim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amino Acid
Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although over 500 amino acids exist in nature, by far the most important are the 22 α-amino acids incorporated into proteins. Only these 22 appear in the genetic code of life. Amino acids can be classified according to the locations of the core structural functional groups ( alpha- , beta- , gamma- amino acids, etc.); other categories relate to polarity, ionization, and side-chain group type ( aliphatic, acyclic, aromatic, polar, 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 on Earth and its emergence. Amino acids are formally named by the IUPAC- IUBMB Joint Commi ...

Sencha
is a type of Japanese 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, 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, and ...

Dimethyl Sulfide
Dimethyl sulfide (DMS) or methylthiomethane is an organosulfur compound with the formula . It is the simplest thioether and has a characteristic disagreeable odor. It is a flammable liquid that boils at . It is a component of the smell produced from cooking of certain vegetables (notably maize, cabbage, and beetroot) and seafoods. It is also an indication of bacterial contamination in malt production and brewing. It is a breakdown product of dimethylsulfoniopropionate (DMSP), and is also produced by the bacterial metabolism of methanethiol. Occurrence and production DMS originates primarily from DMSP, a major secondary metabolite in some marine algae. DMS is the most abundant biological sulfur compound emitted to the atmosphere. Emission occurs over the oceans by phytoplankton. DMS is also produced naturally by bacterial transformation of dimethyl sulfoxide (DMSO) waste that is disposed of into sewers, where it can cause environmental odor problems. DMS is oxidized in ...

Chloroplast
A chloroplast () is a type of membrane-bound organelle, organelle known as a plastid that conducts photosynthesis mostly in plant cell, plant and algae, algal cells. Chloroplasts have a high concentration of chlorophyll pigments which capture the Radiant energy, energy from sunlight and convert it to chemical energy and release oxygen. The chemical energy created is then used to make sugar and other organic molecules from carbon dioxide in a process called the Calvin cycle. Chloroplasts carry out a number of other functions, including fatty acid synthesis, amino acid synthesis, and the immune response in plants. The number of chloroplasts per cell varies from one, in some unicellular algae, up to 100 in plants like ''Arabidopsis'' and wheat. Chloroplasts are highly dynamic—they circulate and are moved around within cells. Their behavior is strongly influenced by environmental factors like light color and intensity. Chloroplasts cannot be made anew by the plant cell and must ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Laver
Green laver (), known as ''aonori'' (; ) in Japan, ''sea cabbage'' () or ''hutai'' () in China, and ''parae'' () and ''kim'' () in Korean, is a type of edible green seaweed, including species from the genera ''Monostroma'' and ''Sea lettuce, Ulva'' (''Ulva prolifera'', ''Ulva pertusa'', ''Ulva intestinalis''). It is commercially cultivated in some bay areas in Japan, Korea, and Taiwan, such as Ise Bay. It is rich in minerals such as calcium, magnesium, lithium, vitamins, and amino acids such as methionine. It is also called ''aosa'' (アオサ, ''Ulva pertusa'') in some places in Japan. Culinary use Japan It is used in its dried form for Japanese soups, ''tempura'', and material for manufacturing dried ''nori'' and ''tsukudani'' and rice. It is also used in a powdered form, often blended with ''Sea lettuce, Ulva'' species of Ulvaceae as its production is limited. It is used commonly for flavouring of some Japanese foods, usually by sprinkling the powder on the hot food, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
