Anethol
Anethole (also known as anise camphor) is an organic compound that is widely used as a flavoring substance. It is a derivative of phenylpropene, a type of aromatic compound that occurs widely in nature, in essential oils. It is in the class of phenylpropanoid organic compounds. It contributes a large component of the odor and flavor of anise and fennel (both in the botanical family Apiaceae), Syzygium anisatum, anise myrtle (Myrtaceae), liquorice (Fabaceae), magnolia blossoms, and star anise (Schisandraceae). Closely related to anethole is its isomer estragole, abundant in tarragon (Asteraceae) and basil (Lamiaceae), that has a flavor reminiscent of anise. It is a colorless, fragrant, mildly volatile liquid. Anethole is only slightly soluble in water but exhibits high solubility in ethanol. This trait causes certain anise-flavored liqueurs to become opaque when diluted with water; the ouzo effect. Structure and production Anethole is an aromatic, Saturated and unsaturated compoun ...

Anise
Anise (; '), also called aniseed or rarely anix is a flowering plant in the family Apiaceae native to Eurasia. The flavor and aroma of its seeds have similarities with some other spices and herbs, such as star anise, fennel, licorice, and tarragon. It is widely cultivated and used to flavor food, candy, and alcoholic drinks, especially around the Mediterranean. Description Anise is an herbaceous annual plant growing to or more. The leaves at the base of the plant are simple, long and shallowly lobed, while leaves higher on the stems are feathery pinnate, divided into numerous small leaflets. The flowers are either white or yellow, approximately in diameter, produced in dense umbels. The fruit is an oblong dry schizocarp, long, usually called "aniseed".Anise (''Pimpinella anisum'' L.) from Gernot Katze ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estragole
Estragole (''p''-allylanisole, methyl chavicol) is a phenylpropene, a natural organic compound. Its chemical structure consists of a benzene ring substituted with a methoxy group and an allyl group. It is an isomer of anethole, differing with respect to the location of the double bond. It is a colorless liquid, although impure samples can appear yellow. It is a component of various trees and plants, including turpentine (pine oil), anise, fennel, bay, tarragon, and basil. It is used in the preparation of fragrances.. The compound is named for ''estragon'', the French name of tarragon. Production Hundreds of tonnes of basil oil are produced annually by steam distillation of ''Ocimum basilicum'' (common basil). This oil is mainly estragole but also contains substantial amounts of linalool. Estragole is the primary constituent of essential oil of tarragon (comprising 60–75%). It is also present in pine oil, turpentine, fennel, anise (2%), ''Clausena anisata'' and '' Syzygi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syzygium Anisatum
:''Should not be confused with Clausena anisata, a small tree native to Southeast Asia and Australia.'' ''Syzygium anisatum'', with common names ringwood and aniseed tree, is a rare Australian rainforest tree with an aromatic leaf that has an essential oil profile comparable to true aniseed. The leaf from cultivated plantations is used as a bushfood spice and distilled for the essential oil, and is known in the trade as aniseed myrtle or anise myrtle. The ringwood tree has a dense crown and grows up to 45 metres tall. The leaves are 6–12 cm long with prominently undulate margins and rich aniseed aroma when crushed. Flowers are white and sweetly scented, borne in panicles. The fruit are dry papery capsules around 5 mm long and are white in appearance. Ringwood's natural distribution in the wild is restricted to the Nambucca and Bellinger Valleys in the subtropics of New South Wales, Australia. Uses Used as a flavouring spice and herbal tea ingredient. Although ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ouzo Effect
The ouzo effect (also louche effect and spontaneous emulsification) is a milky ('' louche'') oil-in-water emulsion that is formed when water is added to ouzo and other anise-flavored liqueurs and spirits, such as pastis, rakı, arak, sambuca and absinthe. Such emulsions occur with only minimal mixing and are highly stable. Observation and explanation The ouzo effect occurs when a strongly hydrophobic essential oil such as ''trans''-anethole is dissolved in a water-miscible solvent, such as ethanol, and the concentration of ethanol is lowered by addition of small amounts of water. Oil-in-water emulsions are not normally stable. Oil droplets coalesce until complete phase separation is achieved at macroscopic levels. Addition of a small amount of surfactant or the application of high shear rates (strong stirring) can stabilize the oil droplets. In a water-rich ouzo mixture the droplet coalescence is dramatically slowed without mechanical agitation, dispersing agents, or surfact ...

Tarragon
Tarragon (''Artemisia dracunculus''), also known as estragon, is a species of perennial herb in the family Asteraceae. It is widespread in the wild across much of Eurasia and North America and is cultivated for culinary and medicinal purposes. One subspecies, ''Artemisia dracunculus'' var. ''sativa'', is cultivated to use the leaves as an aromatic culinary herb. In some other subspecies, the characteristic aroma is largely absent. The species is polymorphic. Informal names for distinguishing the variations include "French tarragon" (best for culinary use), "Russian tarragon," and "wild tarragon" (covers various states). Tarragon grows to tall, with slender branches. The leaves are lanceolate, long and broad, glossy green, with an entire margin. The flowers are produced in small capitula diameter, each capitulum containing up to 40 yellow or greenish-yellow florets. French tarragon, however, seldom produces any flowers (or seeds). Some tarragon plants produce seeds that are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fennel
Fennel (''Foeniculum vulgare'') is a flowering plant species in the carrot family. It is a hardy, perennial herb with yellow flowers and feathery leaves. It is indigenous to the shores of the Mediterranean but has become widely naturalized in many parts of the world, especially on dry soils near the sea-coast and on riverbanks. It is a highly flavorful herb used in cooking and, along with the similar-tasting anise, is one of the primary ingredients of absinthe. Florence fennel or finocchio (, , ) is a selection with a swollen, bulb-like stem base that is used as a vegetable. Description ''Foeniculum vulgare'' is a perennial herb. It is erect, glaucous green, and grows to heights of up to , with hollow stems. The leaves grow up to long; they are finely dissected, with the ultimate segments filiform (threadlike), about wide. (Its leaves are similar to those of dill but thinner.) The flowers are produced in terminal compound umbels wide, each umbel section having 20–5 ...

Anisole
Anisole, or methoxybenzene, is an organic compound with the formula CH3OC6H5. It is a colorless liquid with a smell reminiscent of anise seed, and in fact many of its derivatives are found in natural and artificial fragrances. The compound is mainly made synthetically and is a precursor to other synthetic compounds. It is an ether. Anisole is a standard reagent of both practical and pedagogical value. It can be prepared by the Williamson ether synthesis; sodium phenoxide is reacted with a methyl halide to yield anisole. Reactivity Anisole undergoes electrophilic aromatic substitution reaction at a faster speed than benzene, which in turn reacts more quickly than nitrobenzene. The methoxy group is an ortho/para directing group, which means that electrophilic substitution preferentially occurs at these three sites. The enhanced nucleophilicity of anisole vs. benzene reflects the influence of the methoxy group, which renders the ring more electron-rich. The methoxy group str ...

Star Anise
''Illicium verum'' is a medium-sized evergreen tree native to northeast Vietnam and southwest China. A spice commonly called star anise, staranise, star anise seed, star aniseed, star of anise, Chinese star anise, or badian that closely resembles anise in flavor is obtained from the star-shaped pericarps of the fruit of ''I. verum'' which are harvested just before ripening. Star anise oil is a highly fragrant oil used in cooking, perfumery, soaps, toothpastes, mouthwashes, and skin creams. Until 2012, when they switched to using a bacterial source, Roche Pharmaceuticals used up to 90% of the world's annual star anise crop to produce shikimic acid, a chemical intermediate used in the synthesis of oseltamivir (Tamiflu). Etymology and nomenclature ''Illicium'' comes from the Latin ''illicio'' meaning "entice" or "seduce".Gledhill, David (2008). "The Names of Plants". Cambridge University Press. (hardback), (paperback). pp 210, 400 ''Verum'' means "true" or "genuine". The name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liqueur
A liqueur (; ; ) is an alcoholic drink composed of spirits (often rectified spirit) and additional flavorings such as sugar, fruits, herbs, and spices. Often served with or after dessert, they are typically heavily sweetened and un-aged beyond a resting period during production, when necessary, for their flavors to mingle. Liqueurs are historical descendants of herbal medicines. They were made in Italy as early as the 13th century, often prepared by monks (for example, Chartreuse). Today they are produced all over the world, commonly served neat, over ice, with coffee, in cocktails, and used in cooking. Etymology The French word ''liqueur'' is derived from the Latin ''liquifacere'', which means "to dissolve". In some parts of the United States and Canada, liqueurs may be referred to as cordials, or schnapps. This can cause confusion as in the United Kingdom a cordial would refer to a non-alcoholic concentrated fruit syrup, typically diluted to taste and consumed as a non ...

Liquorice
Liquorice (British English) or licorice (American English) ( ; also ) is the common name of ''Glycyrrhiza glabra'', a flowering plant of the bean family Fabaceae, from the root of which a sweet, aromatic flavouring can be extracted. The liquorice plant is an herbaceous perennial legume native to Western Asia, North Africa, and Southern Europe. Botanically, it is not closely related to anise or fennel, which are sources of similar flavouring compounds. (Another such source, star anise, is even more distantly related from anise and fennel than liquorice, despite its similar common name.) Liquorice is used as a flavouring in candies and tobacco, particularly in some European and West Asian countries. Liquorice extracts have been used in herbalism and traditional medicine. Excessive consumption of liquorice (more than per day of pure glycyrrhizinic acid, a liquorice component) may result in adverse effects, and overconsumption should be suspected clinically in patients presentin ...

Saturated And Unsaturated Compounds
In chemistry, a saturated compound is a chemical compound (or ion) that resists the addition reactions, such as hydrogenation, oxidative addition, and binding of a Lewis acids and bases, Lewis base. The term is used in many contexts and for many classes of chemical compounds. Overall, saturated compounds are less reactive than unsaturated compounds. Saturation is derived from the Latin word ''saturare'', meaning 'to fill'. Organic chemistry Unsaturated compounds generally carry out typical addition reactions that are not possible with saturated compounds such as alkanes. A saturated organic compound has only single bonds between carbon atoms. An important class of saturated compounds are the alkanes. Many saturated compounds have functional groups, e.g., alcohols. Unsaturated organic compounds The concept of saturation can be described using various naming systems, formulas, and Analytical chemistry, analytical tests.
