Cyanin (anthocyanin)
Cyanidin-3,5-''O''-diglucoside, also known as cyanin, is an anthocyanin. It is the 3,5-''O''-diglucoside of cyanidin. Natural occurrences Cyanin can be found in species of the genus ''Rhaponticum'' (Asteraceae). In food Cyanin can be found in red wine as well as pomegranate juice according to a study done by Graça Miguel, Susana Dandlen, Dulce Antunes, Alcinda Neves, and Denise Martins in the winter of 2004. Pomegranate juice extracted through centrifugal seed separation has higher amounts of cyanidin-3,5-''O''-diglucoside than juice extracted by squeezing fruit halves with an electric lemon squeezer.

Anthocyanin
Anthocyanins (), also called anthocyans, are solubility, water-soluble vacuole, vacuolar pigments that, depending on their pH, may appear red, purple, blue, or black. In 1835, the German pharmacist Ludwig Clamor Marquart named a chemical compound that gives flowers a blue color, Anthokyan, in his treatise "''Die Farben der Blüthen''" (English: The Colors of Flowers). Food plants rich in anthocyanins include the blueberry, raspberry, black rice, and black soybean, among many others that are red, blue, purple, or black. Some of the colors of autumn leaves are derived from anthocyanins. Anthocyanins belong to a parent class of molecules called flavonoids synthesized via the phenylpropanoid pathway. They can occur in all biological tissue, tissues of higher plants, including leaf, leaves, plant stem, stems, roots, flowers, and fruits. Anthocyanins are derived from anthocyanidins by adding sugars. They are odorless and moderately astringent. Although approved as food and beverage c ...

Glucoside
A glucoside is a glycoside that is chemically derived from glucose. Glucosides are common in plants, but rare in animals. Glucose is produced when a glucoside is hydrolysed by purely chemical means, or decomposed by fermentation or enzymes. The name was originally given to plant products of this nature, in which the other part of the molecule was, in the greater number of cases, an aromatic aldehydic or phenolic compound (exceptions are Jinigrin and Jalapin or Scammonin). It has now been extended to include synthetic ethers, such as those obtained by acting on alcoholic glucose solutions with hydrochloric acid, and also the polysaccharoses, e.g. cane sugar, which appear to be ethers also. Although glucose is the most common sugar present in glucosides, many are known which yield rhamnose or iso-dulcite; these may be termed pentosides. Much attention has been given to the non-sugar parts (aglycone) of the molecules; the constitutions of many have been determined, and the comp ...

Cyanidin
Cyanidin is a natural organic compound. It is a particular type of anthocyanidin (glycoside version called anthocyanin#Structure, anthocyanins). It is a pigment found in many red berries including grapes, bilberry, blackberry, blueberry, cherry, chokeberry, cranberry, elderberry, Crataegus, hawthorn, loganberry, açai berry and raspberry. It can also be found in other fruits such as apples and plums, and in red cabbage and red onion. It has a characteristic reddish-purple color, though this can change with pH; solutions of the compound are red at pH 11. In certain fruits, the highest concentrations of cyanidin are found in the seeds and skin. Cyanidin has been found to be a potent sirtuin 6 (SIRT6) activator. List of cyanidin derivatives * Antirrhinin (cyanidin-3-rutinoside or 3-C-R), found in black raspberry * Cyanidin-3-xylosylrutinoside, found in black raspberry * Cyanidin-3,4′-di-''O''-β-glucopyranoside, found in red onion * Cyanidin-4′-''O''-β-glucoside, found in ...

Rhaponticum
''Rhaponticum'' is a genus of flowering plants in the tribe Cardueae within the family Asteraceae. , it is accepted by Plants of the World Online, but rejected by the Global Compositae Database in favour of '' Leuzea''. Taxonomy The taxonomic history of the genus name ''Rhaponticum'' is complicated. It has been published at least four times according to the International Plant Names Index. The earliest was by Albrecht von Haller in 1742, which is regarded as an invalid name (''nom. inval.''). The next publication was by Sébastien Vaillant in 1754, also an invalid name. The next was by Christian Gottlieb Ludwig in 1757. This has become a conserved name (nom. cons.), with the conserved type species ''Centaurea rhapontica'' (syn. '' Leuzea rhapontica'' subsp. ''rhapontica''). A subsequent publication by Michel Adanson in 1763 is illegitimate. Combining the genera ''Rhaponticum'' and ''Leuzea'' under the latter name was first suggested by Josef Holub in 1973. A 2006 phylogene ...

Red Wine
Red wine is a type of wine made from dark-colored grape varieties - (red grapes.) The color of the wine can range from intense violet, typical of young wines, through to brick red for mature wines and brown for older red wines. The juice from most purple grapes is greenish-white, the red color coming from anthocyan pigments present in the skin of the grape. Much of the red wine production process involves extraction of color and flavor components from the grape skin. Varieties The top 20 red grape varieties by acreage (listed alphabetically) are: * Alicante Henri Bouschet * Barbera * Bobal * Cabernet Franc * Cabernet Sauvignon * Carignan * Cinsaut * Malbec * Douce noir * Gamay * Grenache * Isabella * Merlot * Montepulciano * Mourvèdre * Pinot noir * Sangiovese * Syrah * Tempranillo * Zinfandel The next top 30 red grape varieties by acreage (listed alphabetically) are: * Aglianico * Blaufränkisch * Bordô * Carménère * Castelão * Concord * ...

Pomegranate
The pomegranate (''Punica granatum'') is a fruit-bearing deciduous shrub in the family Lythraceae, subfamily Punica, Punicoideae, that grows between tall. Rich in symbolic and mythological associations in many cultures, it is thought to have originated from Afghanistan and Iran before being introduced and exported to other parts of Asia, Africa, and Europe. It was introduced into Spanish America in the late 16th century and into California by New Spain, Spanish settlers in 1769. It is widely cultivated throughout West Asia and the Caucasus region, South Asia, Central Asia, North Africa, north and tropical Africa, the drier parts of Southeast Asia, and the Mediterranean Basin. The fruit is typically in season in the Northern Hemisphere from September to February, and in the Southern Hemisphere from March to May. The pomegranate and its juice are variously used in baking, cooking, juice blends, garnish (food), garnishes, non-alcoholic drinks, and cocktails. Etymology The name ...

Lemon Squeezer
A lemon squeezer is a kitchen utensil designed to juicer, extract juice from lemons or other citrus fruit such as oranges, grapefruit, or lime. It is designed to separate and crush the pulp of the fruit in a way that is easy to operate. Lemon squeezers can be made from any solid, acid-resistant material, such as plastic, glass, metal (usually aluminium) or ceramic. History The oldest known lemon squeezers were found in Kütahya, Turkey and date to the first quarter of the 18th century.John Carswell: "The Lemon-Squeezer; an Unique Form of Turkish Pottery" in ''IVème congrès international d’art turc'', pp. 29–45. Éditions de l’Université de Provence, Aix-en-Provence 1971, These ceramic presses are in the traditional style of Turkish pottery of the 18th century and have a superficial resemblance to today's press equipment with cones, though they are designed differently. These examples were individually made, and specially designed for making the then popular citrus dri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phenolic Content In Wine
Phenolic compounds— natural phenol and polyphenols—occur naturally in wine. These include a large group of several hundred chemical compounds that affect the taste, color and mouthfeel of wine. These compounds include phenolic acids, stilbenoids, flavonols, dihydroflavonols, anthocyanins, flavanol monomers ( catechins) and flavanol polymers (proanthocyanidins). This large group of natural phenols can be broadly separated into two categories, flavonoids and non-flavonoids. Flavonoids include the anthocyanins and tannins which contribute to the color and mouthfeel of the wine. The non-flavonoids include the stilbenoids such as resveratrol and phenolic acids such as benzoic, caffeic and cinnamic acids. Origin of the phenolic compounds The natural phenols are not evenly distributed within the grape. Phenolic acids are largely present in the pulp, anthocyanins and stilbenoids in the skin, and other phenols ( catechins, proanthocyanidins and flavonols) in the skin a ...
