Sotolon
Sotolon (also known as sotolone) is a lactone and an extremely powerful aroma compound, with the typical smell of fenugreek or curry at high concentrations and maple syrup, caramel, or burnt sugar at lower concentrations. Sotolon is the major aroma and flavor component of fenugreek seed and lovage, and is one of several aromatic and flavor components of artificial maple syrup. It is also present in molasses, aged rum, aged sake and white wine, flor sherry, roast tobacco, and dried fruiting bodies of the mushroom '' Lactarius helvus''. Sotolon can pass through the body relatively unchanged, and consumption of foods high in sotolon, such as fenugreek, can impart a maple syrup aroma to one's sweat and urine. In some individuals with the genetic disorder maple syrup urine disease, it is spontaneously produced in their bodies and excreted in their urine, leading to the disease's characteristic smell. This molecule is thought to be responsible for the mysterious maple syrup smell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lactarius Helvus
''Lactarius helvus'', commonly known as fenugreek milkcap, is a member of the large milkcap genus '' Lactarius'' in the order Russulales. Fruiting bodies can be found in ''Sphagnum'' moss in coniferous and deciduous woodland in Europe, and possibly North America, although considerable debate continues about the North American variety, formerly referred to as ''Lactarius aquifluus''. Mushrooms are pale brown-grey or beige in colour and funnel-shaped, with colourless, watery milk. Its distinctive smell has been likened to fenugreek, celery, liquorice, or Maggi instant soup. Mildly toxic when raw, it has been implicated in the poisoning of 418 people near Leipzig in October 1949. However, it is used in small quantities as a spice when dried. Sotolon, the agent that gives the fungus its odour, also occurs in fenugreek, maple syrup and lovage. The possible North American variety has a more salmon to pink color with scant watery milk and a strong smell of maple syrup or caramel. In ...

Fenugreek
Fenugreek (; ''Trigonella foenum-graecum'') is an annual plant in the family Fabaceae, with leaves consisting of three small obovate to oblong leaflets. It is cultivated worldwide as a semiarid crop. Its seeds and leaves are common ingredients in dishes from the Indian subcontinent, and have been used as a culinary ingredient since ancient times. Its use as a food ingredient in small quantities is safe. Although sold as a dietary supplement, there is no clinical evidence that fenugreek has therapeutic properties. Commonly used in traditional medicine, fenugreek can increase the risk of serious adverse effects, including allergic reactions. History Fenugreek is believed to have been brought into cultivation in the Near East. It is uncertain which wild strain of the genus ''Trigonella'' gave rise to domesticated fenugreek. Charred fenugreek seeds have been recovered from Tell Halal, Iraq ( carbon dated to 4000 BC), and Bronze Age levels of Lachish and desiccated seeds f ...

Aroma Compound
An aroma compound, also known as an odorant, aroma, fragrance or flavoring, is a chemical compound that has a smell or odor. For an individual chemical or class of chemical compounds to impart a smell or fragrance, it must be sufficiently volatile for transmission via the air to the olfactory system in the upper part of the nose. As examples, various fragrant fruits have diverse aroma compounds, particularly strawberries which are commercially cultivated to have appealing aromas, and contain several hundred aroma compounds. Generally, molecules meeting this specification have molecular weights of less than 310. Flavors affect both the sense of taste and smell, whereas fragrances affect only smell. Flavors tend to be naturally occurring, and the term ''fragrances'' may also apply to synthetic compounds, such as those used in cosmetics. Aroma compounds can naturally be found in various foods, such as fruits and their peels, wine, spices, floral scent, perfumes, frag ...

Vin Jaune
''Vin jaune'' ( French for "yellow wine") is a special and characteristic type of white wine made in the Jura region in eastern France. It is similar to dry fino Sherry and gets its character from being matured in a barrel under a film of yeast, known as the ''voile'', on the wine's surface. ''Vin jaune'' shares many similarities with Sherry, including some aromas, but unlike Sherry, it is not a fortified wine. The wine is made from the Savagnin grape, with some of the most premium examples coming from the marl based vineyards in the Château-Chalon AOC. In other French wine regions, there has been experimentation in producing similar style wines from Chardonnay and other local grape varieties using cultured yeast such as the ''vin de voile'' wine produced in the Gaillac.J. Robinson (ed), ''"The Oxford Companion to Wine"'', Third Edition, p. 750, Oxford University Press 2006, Production Vin jaune is made from late harvest Savagnin grapes, a white variety in the Tr ...

Flavors
Flavor or flavour is either the sensory perception of taste or smell, or a flavoring in food that produces such perception. Flavor or flavour may also refer to: Science *Flavors (programming language), an early object-oriented extension to Lisp * Flavour (particle physics), a quantum number of elementary particles related to their weak interactions *Flavor of Linux, another term for any particular Linux distribution; by extension, "flavor" can be applied to any program or other computer code that exists in more than one current variant at the same time Film and TV * ''Flavors'' (film), romantic comedy concerning Asian-Indian immigrants in America Music Artists and bands * Flavor Flav (born 1959), former rap/hip-hop promoter and current reality television actor * Flavour N'abania (born 1983), Nigerian singer-songwriter * Flavor (band), minor hit with "Sally Had A Party" in 1968 Albums * ''Flavours'' (album), 1975 album by The Guess Who * ''Flavors'' (album), by American ...

Candy Cap
Candy cap or curry milkcap is the English-language common name for several closely related edible species of '' Lactarius''; ''L. camphoratus'', ''L. fragilis'', and ''L. rubidus''. These mushrooms are valued for their highly aromatic qualities and are used culinarily as a flavoring rather than as a constituent of a full meal. Description and classification Candy caps are small to medium-size mushrooms, with a pileus ranging from 2–5 cm in diameter (though ''L. rubidus'' and ''L. rufulus'' can be slightly larger), and with coloration ranging through various burnt orange to burnt orange-red to orange-brown shades. The pileus shape ranges from broadly convex in young specimens to plane to slightly depressed in older ones; lamellae are attached to subdecurrent. The entire fruiting body is quite fragile and brittle. Like all members of ''Lactarius'', the fruiting body exudes a latex when broken, which in these species is whitish and watery in appearance, and is often compar ...

Chirality (chemistry)
In chemistry, a molecule or ion is called chiral () if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (). The terms are derived from Ancient Greek χείρ (''cheir'') 'hand'; which is the canonical example of an object with this property. A chiral molecule or ion exists in two stereoisomers that are mirror images of each other, called enantiomers; they are often distinguished as either "right-handed" or "left-handed" by their absolute configuration or some other criterion. The two enantiomers have the same chemical properties, except when reacting with other chiral compounds. They also have the same physical properties, except that they often have opposite optical activities. A homogeneous mixture of the two enantiomers in equal parts is said to be racemic, and it usually differs chemically and physically from the pure enantiomers. Chiral molecules ...

Enol
In organic chemistry, alkenols (shortened to enols) are a type of reactive structure or intermediate in organic chemistry that is represented as an alkene ( olefin) with a hydroxyl group attached to one end of the alkene double bond (). The terms ''enol'' and ''alkenol'' are portmanteaus deriving from "-ene"/"alkene" and the "-ol" suffix indicating the hydroxyl group of alcohols, dropping the terminal "-e" of the first term. Generation of enols often involves removal of a hydrogen adjacent (α-) to the carbonyl group—i.e., deprotonation, its removal as a proton, . When this proton is not returned at the end of the stepwise process, the result is an anion termed an enolate (see images at right). The enolate structures shown are schematic; a more modern representation considers the molecular orbitals that are formed and occupied by electrons in the enolate. Similarly, generation of the enol often is accompanied by "trapping" or masking of the hydroxy group as an ether, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific American
''Scientific American'', informally abbreviated ''SciAm'' or sometimes ''SA'', is an American popular science magazine. Many famous scientists, including Albert Einstein and Nikola Tesla, have contributed articles to it. In print since 1845, it is the oldest continuously published magazine in the United States. ''Scientific American'' is owned by Springer Nature, which in turn is a subsidiary of Holtzbrinck Publishing Group. History ''Scientific American'' was founded by inventor and publisher Rufus Porter in 1845 as a four-page weekly newspaper. The first issue of the large format newspaper was released August 28, 1845. Throughout its early years, much emphasis was placed on reports of what was going on at the U.S. Patent Office. It also reported on a broad range of inventions including perpetual motion machines, an 1860 device for buoying vessels by Abraham Lincoln, and the universal joint which now can be found in nearly every automobile manufactured. Current issues includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maple Syrup Event
The maple syrup event was the presence of a particular scent in New York City in the late 2000s, and the response to this smell by the residents, various media outlets, and government agencies. History Reports of the event are said to have begun in the fall of 2005, as first reported by Gothamist and continued sporadically into early 2009. New Yorkers feared the sweet smell was a form of chemical warfare. The scent was eventually traced to its source, a Frutarom Industries Ltd. factory in northern New Jersey, which was processing fenugreek seeds, commonly used in maple syrup substitutes. This source was traced through a collaborative process between the citizens of New York City, the city's 311 system, the New York City Office of Emergency Management, the New York City Department of Environmental Protection, and a working group which gathered and analyzed atmospheric data. Popular culture The Maple Syrup event was featured, without mentioning it by name, in " 30 Rock" Season ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lactone
Lactones are cyclic carboxylic esters, containing a 1-oxacycloalkan-2-one structure (), or analogues having unsaturation or heteroatoms replacing one or more carbon atoms of the ring. Lactones are formed by intramolecular esterification of the corresponding hydroxycarboxylic acids, which takes place spontaneously when the ring that is formed is five- or six-membered. Lactones with three- or four-membered rings (α-lactones and β-lactones) are very reactive, making their isolation difficult. Special methods are normally required for the laboratory synthesis of small-ring lactones as well as those that contain rings larger than six-membered. Nomenclature Lactones are usually named according to the precursor acid molecule (''aceto'' = 2 carbon atoms, ''propio'' = 3, ''butyro'' = 4, ''valero'' = 5, ''capro'' = 6, etc.), with a ''-lactone'' suffix and a Greek letter prefix that specifies the number of carbon atoms in the heterocycle — that is, the distance between the relevant -OH ...
