Coffee Bean
A coffee bean is a seed of the ''Coffea'' plant and the source for coffee. It is the pip inside the red or purple fruit often referred to as a coffee cherry. Just like ordinary cherries, the coffee fruit is also a so-called stone fruit. Even though the coffee beans are not technically beans, they are referred to as such because of their resemblance to true beans. The fruits; cherries or berries, most commonly contain two stones with their flat sides together. A small percentage of cherries contain a single seed, instead of the usual two. This is called a "peaberry". The peaberry occurs only between 10% and 15% of the time, and it is a fairly common (yet scientifically unproven) belief that they have more flavour than normal coffee beans. Like Brazil nuts (a seed) and white rice, coffee beans consist mostly of endosperm. The two most economically important varieties of coffee plant are the Arabica and the Robusta; approximately 60% of the coffee produced worldwide is Arabica and ...

Camellia Sinensis
''Camellia sinensis'' is a species of evergreen shrub or small tree in the flowering plant family Theaceae. Its leaves and leaf buds are used to produce the popular beverage, tea. Common names include tea plant, tea shrub, and tea tree (not to be confused with ''Melaleuca alternifolia'', the source of tea tree oil, or the genus ''Leptospermum'' commonly called tea tree). White tea, yellow tea, green tea, oolong, dark tea (which includes pu-erh tea) and black tea are all harvested from one of two major varieties grown today, ''C. sinensis'' var. ''sinensis'' and ''C. s.'' var. ''assamica'', but are processed differently to attain varying levels of oxidation with black tea being the most oxidized and green being the least. Kukicha (twig tea) is also harvested from ''C. sinensis'', but uses twigs and stems rather than leaves. Nomenclature and taxonomy The generic name ''Camellia'' is taken from the Latinized name of Rev. Georg Kamel, SJ (1661–1706), a Moravian-born Jesuit ...

Cola Nuts
The term kola nut usually refers to the seeds of certain species of plant of the genus ''Cola'', placed formerly in the cocoa family Sterculiaceae and now usually subsumed in the mallow family Malvaceae (as subfamily Sterculioideae). These cola species are trees native to the tropical rainforests of Africa. Their caffeine-containing seeds are used as flavoring ingredients in beverages applied to various carbonated soft drinks, from which the name ''cola'' originates. General description The kola nut is a caffeine-containing nut of evergreen trees of the genus ''Cola'', primarily of the species ''Cola acuminata'' and ''Cola nitida''. ''Cola acuminata'', an evergreen tree about 20 meters in height, has long, ovoid leaves pointed at both the ends with a leathery texture. The trees have cream flowers with purplish-brown striations, and star-shaped fruit consisting of usually 5 follicles. Inside each follicle, about a dozen prismatic seeds develop in a white seed-shell. The nut†... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guarana
Guaraná ( from the Portuguese ''guaraná'' ), ''Paullinia cupana'', syns. ''P. crysan, P. sorbilis'') is a climbing plant in the family Sapindaceae, native to the Amazon basin and especially common in Brazil. Guaraná has large leaves and clusters of flowers, and is best known for the seeds from its fruits, which are about the size of a coffee bean. As a dietary supplement or herb, guaraná seed is an effective stimulant: it contains about twice the concentration of caffeine found in coffee beans (about 2–8% caffeine in guarana seeds, compared to about 1–3% for coffee beans). The additive has gained notoriety for being used in energy drinks. As with other plants producing caffeine, the high concentration of caffeine is a defensive toxin that repels herbivores from the berry and its seeds. The colour of the fruit ranges from brown to red and it contains black seeds that are partly covered by white arils. The colour contrast when the fruit is split open has been compa ...

Cocoa Bean
The cocoa bean (technically cocoa seed) or simply cocoa (), also called the cacao bean (technically cacao seed) or cacao (), is the dried and fully fermented seed of ''Theobroma cacao'', from which cocoa solids (a mixture of nonfat substances) and cocoa butter (the fat) can be extracted. Cocoa beans are the basis of chocolate, and Mesoamerican foods including tejate, an indigenous Mexican drink that also includes maize, and pinolillo, a similar Nicaraguan drink made from a cornmeal & cocoa powder. Etymology The word ''cocoa'' comes from the Spanish word , which is derived from the Nahuatl word . The Nahuatl word, in turn, ultimately derives from the reconstructed Proto-Mixe–Zoquean word ''kakawa''. Used on its own, the term ''cocoa'' may also mean: * Hot cocoa, the drink more known as ''hot chocolate'' Terms derived from ''cocoa'' include: * Cocoa paste, ground cocoa beans: the mass is melted and separated into: ** Cocoa butter, a pale, yellow, edible fat ** Cocoa s ...

Yerba Mate
Yerba mate or yerba-maté (''Ilex paraguariensis''; from Spanish ; pt, erva-mate, or ; gn, ka'a, ) is a plant species of the holly genus ''Ilex'' native to South America. It was named by the French botanist Augustin Saint-Hilaire. The leaves of the plant can be steeped in hot water to make a beverage known as ''mate''. Brewed cold, it is used to make ''tereré''. Both the plant and the beverage contain caffeine. The indigenous Guaranà and some Tupà communities (whose territory covered present-day Paraguay) first cultivated and consumed yerba mate prior to European colonization of the Americas. Its consumption was exclusive to the natives of only two regions of the territory that today is Paraguay, more specifically the departments of Amambay and Alto Paraná. After the Jesuits discovered its commercialization potential, yerba mate became widespread throughout the province and even elsewhere in the Spanish Crown. Mate is traditionally consumed in central and southern regi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xanthines
Xanthine ( or ; archaically xanthic acid; systematic name 3,7-dihydropurine-2,6-dione) is a purine base found in most human body tissues and fluids, as well as in other organisms. Several stimulants are derived from xanthine, including caffeine, theophylline, and theobromine. Xanthine is a product on the pathway of purine degradation. * It is created from guanine by guanine deaminase. * It is created from hypoxanthine by xanthine oxidoreductase. * It is also created from xanthosine by purine nucleoside phosphorylase. Xanthine is subsequently converted to uric acid by the action of the xanthine oxidase enzyme. Use and manufacturing Xanthine is used as a drug precursor for human and animal medications, and is manufactured as a pesticide ingredient. Clinical significance Derivatives of xanthine (known collectively as xanthines) are a group of alkaloids commonly used for their effects as mild stimulants and as bronchodilators, notably in the treatment of asthma or influenza symptom ...

Alkaloids
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.Chemical Encyclopedia: alkaloids xumuk.ru Alkaloids are produced by a large variety of organisms including , , |
