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 Queb ...

Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. He is sometimes called the Mycology, "Linnaeus of Mycology". In his works he described and assigned botanical names to hundreds of fungus and lichen species, many of which remain authoritative today. Career Fries was born at Femsjö (Hylte Municipality), Småland, the son of the pastor there. He attended school in Växjö. He acquired an extensive knowledge of flowering plants from his father. In 1811 Fries entered Lund University where he studied under Carl Adolph Agardh and Anders Jahan Retzius. He obtained his doctorate in 1814. In the same year he was appointed an associate professorship in botany. Fries edited several exsiccata series, the first starting in 1818 under the title ''Lichenes Sveciae exsiccati, curante Elia Fries'' and the last together with Franz Joseph Lagger under the title ''Hieracia europaea exsiccata''. He was elected a member of the Royal Swedish Academ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flor
Flor (Spanish and Portuguese for ''flower'') in winemaking, is a film of yeast on the surface of wine, important in the manufacture of some styles of sherry. The flor is formed naturally under certain winemaking conditions, from indigenous yeasts found in the region of Andalucía in southern Spain. Normally in winemaking, it is essential to keep young wines away from exposure to air by sealing them in airtight barrels, to avoid contamination by bacteria and yeasts that tend to spoil it. However, in the manufacture of sherries, the slightly porous oak barrels are deliberately filled only about five-sixths full with the young wine, leaving "the space of two fists" empty to allow the flor yeast to take form and the bung is not completely sealed. The flor favors cooler climates and higher humidity, so the sherries produced in the coastal Sanlúcar de Barrameda and El Puerto de Santa María have a thicker cap of flor than those produced inland in Jerez. The yeast gives the resulting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sake
Sake, , or saki, also referred to as Japanese rice wine, is an alcoholic beverage of Japanese origin made by fermenting rice that has been polished to remove the bran. Despite the name ''Japanese rice wine'', sake, and indeed any East Asian rice wine (such as huangjiu and cheongju), is produced by a brewing process more akin to that of beer, where starch is converted into sugars that ferment into alcohol, whereas in wine, alcohol is produced by fermenting sugar that is naturally present in fruit, typically grapes. The brewing process for sake differs from the process for beer, where the conversion from starch to sugar and then from sugar to alcohol occurs in two distinct steps. Like other rice wines, when sake is brewed, these conversions occur simultaneously. The alcohol content differs between sake, wine, and beer; while most beer contains 3–9% ABV, wine generally contains 9–16% ABV, and undiluted sake contains 18–20% ABV (although this is often lowered to abou ...

Molasses
Molasses () is a viscous byproduct, principally obtained from the refining of sugarcane or sugar beet juice into sugar. Molasses varies in the amount of sugar, the method of extraction, and the age of the plant. Sugarcane molasses is usually used to sweeten and flavour foods. Molasses is a major constituent of fine commercial brown sugar. Molasses is rich in vitamins and minerals, including vitamin B6, iron, calcium, magnesium, and potassium. There are different types of molasses depending on the amount of time refined, including first molasses (highest sugar content), second molasses (slightly bitter), and blackstrap molasses (the darkest and most robust in flavor). Molasses was historically popular in the Americas before the 20th century as a sweetener. It is still commonly used in traditional cuisine, such as in Madeira Island's traditional dishes. In addition to culinary uses, molasses has industrial applications, such as in the distillation of rum, as an additiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sotolon
Sotolon (also known as sotolone) is a butenolide lactone and an extremely potent 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, sotolon 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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sesquiterpene
Sesquiterpenes are a class of terpenes that consist of three isoprene units and often have the molecular formula C15H24. Like monoterpenes, sesquiterpenes may be cyclic or contain rings, including many combinations. Biochemical modifications such as oxidation or rearrangement produce the related sesquiterpenoids. It is estimated (2006) that 3000 sesquiterpenes have been identified. Biosynthesis and examples The reaction of geranyl pyrophosphate with isopentenyl pyrophosphate results in the 15-carbon farnesyl pyrophosphate (FPP), which is an intermediate in the biosynthesis of sesquiterpenes such as farnesene. Cyclic sesquiterpenes are more common than cyclic monoterpenes because of the increased chain length and additional double bond in the sesquiterpene precursors. In addition to common six-membered ring systems such as the ones found in zingiberene and bisacurone, cyclization of one end of the chain to the other end can lead to macrocyclic rings such as humulene. ...

Vertigo (medical)
Vertigo is a condition in which a person has the sensation that they are moving, or that objects around them are moving, when they are not. Often it feels like a spinning or swaying movement. It may be associated with nausea, vomiting, perspiration, or difficulties walking. It is typically worse when the head is moved. Vertigo is the most common type of dizziness. The most common disorders that result in vertigo are benign paroxysmal positional vertigo (BPPV), Ménière's disease, and vestibular neuritis. Less common causes include stroke, brain tumors, brain injury, multiple sclerosis, migraines, trauma, and uneven pressures between the middle ears. Physiologic vertigo may occur following being exposed to motion for a prolonged period such as when on a ship or simply following spinning with the eyes closed. Other causes may include toxin exposures such as to carbon monoxide, alcohol, or aspirin. Vertigo typically indicates a problem in a part of the vestibular system. ...

Mushroom Poisoning
Mushroom poisoning is poisoning resulting from the ingestion of mushrooms that contain toxicity, toxic substances. Signs and symptoms, Symptoms can vary from slight Gastrointestinal tract, gastrointestinal discomfort to death in about 10 days. Mushroom toxins are secondary metabolites produced by the fungus. Mushroom poisoning is usually the result of ingestion of wild mushrooms after misidentification of a Mycotoxin, toxic mushroom as an edible species. The most common reason for this misidentification is a close resemblance in terms of color and general Morphology (biology), morphology of the toxic mushrooms species with edible species. To prevent mushroom poisoning, mushroom gatherers familiarize themselves with the mushrooms they intend to collect, as well as with any similar-looking toxic species. The safety of eating wild mushrooms may depend on methods of preparation for cooking. Some toxins, such as amatoxins, are Thermostability, thermostable and mushrooms containing such ...

Beech
Beech (genus ''Fagus'') is a genus of deciduous trees in the family Fagaceae, native to subtropical (accessory forest element) and temperate (as dominant element of Mesophyte, mesophytic forests) Eurasia and North America. There are 14 accepted species in two distinct subgenera, ''Englerianae'' and ''Fagus''. The subgenus ''Englerianae'' is found only in East Asia, distinctive for its low branches, often made up of several major trunks with yellowish bark. The better known species of subgenus ''Fagus'' are native to Europe, western and eastern Asia and eastern North America. They are high-branching trees with tall, stout trunks and smooth silver-grey bark. The European beech ''Fagus sylvatica'' is the most commonly cultivated species, yielding a utility timber used for furniture construction, flooring and engineering purposes, in plywood, and household items. The timber can be used to build homes. Beechwood makes excellent firewood. Slats of washed beech wood are spread around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birch
A birch is a thin-leaved deciduous hardwood tree of the genus ''Betula'' (), in the family Betulaceae, which also includes alders, hazels, and hornbeams. It is closely related to the beech- oak family Fagaceae. The genus ''Betula'' contains 30 to 60 known taxa of which 11 are on the IUCN 2011 Red List of Threatened Species. They are typically short-lived pioneer species and are widespread in the Northern Hemisphere, particularly in northern areas of temperate climates and in boreal climates. Birch wood is used for a wide range of purposes. Description Birch species are generally small to medium-sized trees or shrubs, mostly of northern temperate and boreal climates. The simple leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate. They often appear in pairs, but these pairs are really borne on spur-like, two-leaved, lateral branchlets. The fruit is a small samara, although the wings may be obscure in some species. They differ from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
