|Allium sativum, known as garlic, from William Woodville, Medical Botany, 1793.|
Garlic (Allium sativum) is a species of bulbous flowering plant in the onion genus Allium . Its close relatives include the onion, shallot, leek, chive,Welsh onion and Chinese onion. It is native to Central Asia and northeastern Iran and has long been a common seasoning worldwide, with a history of several thousand years of human consumption and use. It was known to ancient Egyptians and has been used as both a food flavoring and a traditional medicine. China produces some 80% of the world's supply of garlic.
The word garlic derives from Old English, garlēac, meaning gar (spear) and leek, as a 'spear-shaped leek'.
Allium sativum is a perennial flowering plant growing from a bulb. It has a tall, erect flowering stem that grows up to 1 m (3 ft). The leaf blade is flat, linear, solid, and approximately 1.25–2.5 cm (0.5–1.0 in) wide, with an acute apex. The plant may produce pink to purple flowers from July to September in the Northern Hemisphere. The bulb is odoriferous and contains outer layers of thin sheathing leaves surrounding an inner sheath that encloses the clove. Often the bulb contains 10 to 20 cloves that are asymmetric in shape, except for those closest to the center. If garlic is planted at the proper time and depth, it can be grown as far north as Alaska. It produces hermaphrodite flowers. It is pollinated by bees, butterflies, moths, and other insects.

Identification of the wild progenitor of common garlic is difficult due to the sterility of its many cultivars, which limits the ability to cross test with wild relatives. Genetically and morphologically, garlic is most similar to the wild species Allium longicuspis, which grows in central and southwestern Asia.However, because Allium longicuspis is also mostly sterile, it is doubtful that it is the ancestor of Allium sativum. Other candidates that have been suggested include Allium tuncelianum , Allium macrochaetum , and Allium truncatum , all of which are native to the Middle East.
Allium sativum grows in the wild in areas where it has become naturalized. The "wild garlic", "crow garlic", and "field garlic" of Britain are members of the species Allium ursinum , Allium vineale , and Allium oleraceum , respectively. In North America, Allium vineale (known as "wild garlic" or "crow garlic") and Allium canadense (known as "meadow garlic", "wild garlic", or "wild onion") are common weeds in fields.So-called elephant garlic is actually a wild leek ( Allium ampeloprasum ), and not a true garlic. Single clove garlic (also called pearl or solo garlic) originated in the Yunnan province of China.
Some garlics have protected status in Europe,including:

There are two subspecies of A. sativum,ten major groups of varieties, and hundreds of varieties or cultivars.
There are at least 120 cultivars originating from Central Asia, making it the main center of garlic biodiversity.
Garlic is easy to grow and can be grown year-round in mild climates.While sexual propagation of garlic is possible, nearly all of the garlic in cultivation is propagated asexually, by planting individual cloves in the ground. In colder climates, cloves are best planted about six weeks before the soil freezes. The goal is to have the bulbs produce only roots and no shoots above the ground. Harvest is in late spring or early summer.
Garlic plants can be grown closely together, leaving enough space for the bulbs to mature, and are easily grown in containers of sufficient depth. Garlic does well in loose, dry, well-drained soils in sunny locations, and is hardy throughout USDA climate zones 4–9. When selecting garlic for planting, it is important to pick large bulbs from which to separate cloves. Large cloves, along with proper spacing in the planting bed, will also increase bulb size. Garlic plants prefer to grow in a soil with a high organic material content, but are capable of growing in a wide range of soil conditions and pH levels.
There are different varieties or subspecies of garlic, most notably hardneck garlic and softneck garlic.The latitude where the garlic is grown affects the choice of type, as garlic can be day-length sensitive. Hardneck garlic is generally grown in cooler climates and produces relatively large cloves, whereas softneck garlic is generally grown closer to the equator and produces small, tightly-packed cloves.
Garlic scapes are removed to focus all the garlic's energy into bulb growth. The scapes can be eaten raw or cooked.
Garlic plants are usually hardy and not affected by many pests or diseases. Garlic plants are said to repel rabbits and moles.The California Department of Food and Agriculture (CDFA) conducts a certification program to assure freedom from nematode and white rot disease caused by Stromatinia cepivora , two pathogens that can both destroy a crop as well as remain in the soil indefinitely, once introduced. Garlic may also suffer from pink root, a typically non-fatal disease that stunts the roots and turns them pink or red; or leek rust. The larvae of the leek moth attack garlic by mining into the leaves or bulbs.

In 2018, world production of garlic was 28.5 million tonnes, with China alone accounting for 78% of the total.
Fresh or crushed garlic yields the sulfur-containing compounds allicin, ajoene, diallyl polysulfides, vinyldithiins, and S-allylcysteine; as well as enzymes, saponins, flavonoids, and Maillard reaction products, which are not sulfur-containing compounds.
The phytochemicals responsible for the sharp flavor of garlic are produced when the plant's cells are damaged. When a cell is broken by chopping, chewing, or crushing, enzymes stored in cell vacuoles trigger the breakdown of several sulfur-containing compounds stored in the cell fluids (cytosol).The resultant compounds are responsible for the sharp or hot taste and strong smell of garlic. Some of the compounds are unstable and continue to react over time.
Among the members of the onion family, garlic has by far the highest concentrations of initial reaction products, making garlic much more potent than onion, shallot, or leeks. [ citation needed ]Although many humans enjoy the taste of garlic, these compounds are believed to have evolved as a defensive mechanism, deterring animals such as birds, insects, and worms from eating the plant. Because of this, people throughout history have used garlic to keep away pests such as mosquitoes and slugs.
A large number of sulfur compounds contribute to the smell and taste of garlic. Allicin has been found to be the compound most responsible for the "hot" sensation of raw garlic. This chemical opens thermo-transient receptor potential channels that are responsible for the burning sense of heat in foods. The process of cooking garlic removes allicin, thus mellowing its spiciness.Allicin, along with its decomposition products diallyl disulfide and diallyl trisulfide, are major contributors to the characteristic odor of garlic, with other allicin-derived compounds, such as vinyldithiins and ajoene.
Because of its strong odor, garlic is sometimes called the "stinking rose". When eaten in quantity, garlic may be strongly evident in the diner's sweat and garlic breath the following day. This is because garlic's strong-smelling sulfur compounds are metabolized, forming allyl methyl sulfide. Allyl methyl sulfide (AMS) cannot be digested and is passed into the blood. It is carried to the lungs and the skin, where it is excreted. Since digestion takes several hours, and release of AMS several hours more, the effect of eating garlic may be present for a long time.
The well-known phenomenon of "garlic breath" is allegedly alleviated by eating fresh parsley.The herb is, therefore, included in many garlic recipes, such as pistou , persillade , and the garlic butter spread used in garlic bread.
Because of the AMS in the bloodstream, it is believed by some to act as a mosquito repellent, but no clinically reported evidence suggests it is actually effective.
Abundant sulfur compounds in garlic are also responsible for turning garlic green or blue during pickling and cooking. Under these conditions (i.e., acidity, heat) the sulfur-containing compound alliin reacts with common amino acids to make pyrroles, clusters of carbon-nitrogen rings.These rings can be linked together into polypyrrole molecules. Ring structures absorb particular wavelengths of light and thus appear colored. The two-pyrrole molecule looks red, the three-pyrrole molecule looks blue, and the four-pyrrole molecule looks green (like chlorophyll, a tetrapyrrole). Like chlorophyll, the pyrrole pigments are safe to eat.
Upon cutting, similar to a color change in onion caused by reactions of amino acids with sulfur compounds,garlic can turn green.
Numerous cuneiform records show that garlic has been cultivated in Mesopotamia for at least 4,000 years. 1325 BC). It was consumed by ancient Greek and Roman soldiers, sailors, and rural classes (Virgil, Eclogues ii. 11), and, according to Pliny the Elder ( Natural History xix. 32), by the African peasantry. Garlic was placed by the ancient Greeks on the piles of stones at crossroads, as a supper for Hecate (Theophrastus, Characters, The Superstitious Man).The use of garlic in China and Egypt also dates back thousands of years. Well-preserved garlic was found in the tomb of Tutankhamun (c.
Garlic was rare in traditional English cuisine (though it is said to have been grown in England before 1548) but has been a common ingredient in Mediterranean Europe. c. 1300 Assize of Weights and Measures, an English statute generally dated to the 13th century, indicate a passage as dealing with standardized units of garlic production, sale, and taxation — the hundred of 15 ropes of 15 heads each – but the Latin version of the text may refer to herring rather than garlic.Translations of the
Garlic has been used for traditional medicine in diverse cultures such as in Egypt, Japan, China, Rome, and Greece. 99). Avicenna, in The Canon of Medicine (1025), recommended garlic for the treatment of arthritis, snake and insect bites, parasites, chronic cough, and as an antibiotic.[ medical citation needed ] Alexander Neckam, a writer of the 12th century (see Wright's edition of his works, p. 473, 1863), discussed it as a palliative for the heat of the sun in field labor. In the 17th century, Thomas Sydenham valued it as an application in confluent smallpox, and William Cullen's Materia Medica of 1789 found some dropsies cured by it alone.In his Natural History , Pliny gave a list of conditions in which garlic was considered beneficial (N.H. xx. 23). Galen, writing in the second century, eulogized garlic as the "rustic's theriac" (cure-all) (see F. Adams' Paulus Aegineta, p.
Garlic is widely used around the world for its pungent flavor as a seasoning or condiment.
The garlic plant's bulb is the most commonly used part of the plant. With the exception of the single clove types, garlic bulbs are normally divided into numerous fleshy sections called cloves. Garlic cloves are used for consumption (raw or cooked) or for medicinal purposes. They have a characteristic pungent, spicy flavor that mellows and sweetens considerably with cooking.The distinctive aroma is mainly due to organosulfur compounds including allicin present in fresh garlic cloves and ajoene which forms when they are crushed or chopped. A further metabolite allyl methyl sulfide is responsible for garlic breath.
Other parts of the garlic plant are also edible. The leaves and flowers (bulbils) on the head (spathe) are sometimes eaten. They are milder in flavor than the bulbs,and are most often consumed while immature and still tender. Immature garlic is sometimes pulled, rather like a scallion, and sold as "green garlic". When green garlic is allowed to grow past the "scallion" stage, but not permitted to fully mature, it may produce a garlic "round", a bulb like a boiling onion, but not separated into cloves like a mature bulb.
Green garlic imparts a garlic flavor and aroma in food, minus the spiciness. Green garlic is often chopped and stir-fried or cooked in soup or hot pot in Southeast Asian (i.e. Vietnamese, Thai, Myanmar, Lao, Cambodian, Singaporean), and Chinese cookery, and is very abundant and low-priced. Additionally, the immature flower stalks (scapes) of the hardneck and elephant types are sometimes marketed for uses similar to asparagus in stir-fries.
Inedible or rarely eaten parts of the garlic plant include the "skin" covering each clove and root cluster. The papery, protective layers of "skin" over various parts of the plant are generally discarded during preparation for most culinary uses, though in Korea immature whole heads are sometimes prepared with the tender skins intact.The root cluster attached to the basal plate of the bulb is the only part not typically considered palatable in any form.
An alternative is to cut the top off the bulb, coat the cloves by dribbling olive oil (or other oil-based seasoning) over them, and roast them in an oven. Garlic softens and can be extracted from the cloves by squeezing the (root) end of the bulb, or individually by squeezing one end of the clove. In Korea, heads of garlic are heated over the course of several weeks; the resulting product, called black garlic, is sweet and syrupy, and is exported to the United States, United Kingdom, and Australia.
Garlic may be applied to different kinds of bread, usually in a medium of butter or oil, to create a variety of classic dishes, such as garlic bread, garlic toast, bruschetta, crostini, and canapé. The flavor varies in intensity and aroma with the different cooking methods. It is often paired with onion, tomato, or ginger.
Immature scapes are tender and edible. They are also known as "garlic spears", "stems", or "tops". Scapes generally have a milder taste than the cloves. They are often used in stir frying or braised like asparagus.Garlic leaves are a popular vegetable in many parts of Asia. The leaves are cut, cleaned, and then stir-fried with eggs, meat, or vegetables.
Garlic powder is made from dehydrated garlic and can be used as a substitute for fresh garlic, though the taste is not quite the same. Garlic salt combines garlic powder with table salt.
Garlic is a fundamental component in many or most dishes of various regions, including eastern Asia, South Asia, Southeast Asia, the Middle East, northern Africa, southern Europe, and parts of Latin America.Latin American seasonings, particularly, use garlic in sofritos and mofongos.
Oils can be flavored with garlic cloves. These infused oils are used to season all categories of vegetables, meats, breads, and pasta. Garlic, along with fish sauce, chopped fresh chilis, lime juice, sugar, and water, is a basic essential item in dipping fish sauce, a highly used dipping sauce condiment used in Indochina. In East and Southeast Asia, chili oil with garlic is a popular dipping sauce, especially for meat and seafood. Tuong ot toi Viet Nam (Vietnam chili garlic sauce) is a highly popular condiment and dip across North America and Asia.
In some cuisines, the young bulbs are pickled for three to six weeks in a mixture of sugar, salt, and spices. In eastern Europe, the shoots are pickled and eaten as an appetizer. Laba garlic, prepared by soaking garlic in vinegar, is a type of pickled garlic served with dumplings in northern China to celebrate the Chinese New Year.
Garlic is essential in Middle Eastern and Arabic cooking, with its presence in many food items. In Levantine countries such as Jordan and Lebanon, garlic is traditionally crushed together with olive oil, and occasionally salt, to create a Middle Eastern garlic sauce called Toum (تُوم; meaning "garlic" in Arabic). While not exclusively served with meats, toum is commonly paired with chicken or other meat dishes such as shawarma. Garlic is also a key component in some hummus varieties, an Arabic dip composed of chickpeas, tahini, garlic, lemon juice, and salt.
Lightly smoked garlic is used in British and other European cuisine. It is particularly prized for stuffing poultry and game, and in soups and stews.
Emulsifying garlic with olive oil produces aioli . Garlic, oil, and a chunky base produce skordalia . Blending garlic, almond, oil, and soaked bread produces ajoblanco . Tzatziki , yogurt mixed with garlic and salt, is a common sauce in Eastern Mediterranean cuisines.
Domestically, garlic is stored warm [above 18 °C (64 °F)] and dry to keep it dormant (to inhibit sprouting). It is traditionally hung; softneck varieties are often braided in strands called plaits or grappes. Peeled cloves may be stored in wine or vinegar in the refrigerator. Commercially, garlic is stored at 0 °C (32 °F), in a dry, low-humidity environment. Garlic will keep longer if the tops remain attached.
Garlic is often kept in oil to produce flavored oil; however, the practice requires measures to be taken to prevent the garlic from spoiling which may include rancidity and growth of Clostridium botulinum .Acidification with a mild solution of vinegar minimizes bacterial growth. Refrigeration does not assure the safety of garlic kept in oil, requiring use within one month to avoid bacterial spoilage. Garlic is also dried at low temperatures, to preserve the enzymatic activity and sold and kept as garlic granules, and can be rehydrated to reactivate it.
Stored garlic can be affected by Penicillium decay known as ”blue mold” (or ”green mold” in some locales), especially in high humidity.Infection may first appear as soft or water-soaked spots, followed by white patches (of mycelium) which turn blue or green with sporulation. As sporulation and germination are delayed at low temperature, and at -4 deg. C are inhibited entirely, in refrigerated cloves one may only see the white mycellium during early stages. Penicillium hirsutum and Penicillium allii are two of the predominant species identified in blue mold.
As of 2015, clinical research to determine the effects of consuming garlic on hypertension found that consuming garlic produces only a small reduction in blood pressure (4 mmHg),and there is no clear long-term effect on cardiovascular morbidity and mortality. A 2016 meta-analysis indicated there was no effect of garlic consumption on blood levels of lipoprotein(a), a biomarker of atherosclerosis. Because garlic might reduce platelet aggregation, people taking anticoagulant medication are cautioned about consuming garlic.
A 2016 meta-analysis of case-control and cohort studies found a moderate inverse association between garlic intake and some cancers of the upper digestive tract.Another meta-analysis found decreased rates of stomach cancer associated with garlic intake, but cited confounding factors as limitations for interpreting these studies. Further meta-analyses found similar results on the incidence of stomach cancer by consuming allium vegetables including garlic. A 2014 meta-analysis of observational epidemiological studies found that garlic consumption was associated with a lower risk of stomach cancer in Korean people.
A 2016 meta-analysis found no effect of garlic on colorectal cancer.A 2014 meta-analysis found garlic supplements or allium vegetables to have no effect on colorectal cancers.
A 2013 meta-analysis of case-control and cohort studies found limited evidence for an association between higher garlic consumption and reduced risk of prostate cancer, but the studies were suspected as having publication bias.A 2013 meta-analysis of epidemiological studies found garlic intake to be associated with decreased risk of prostate cancer.
A 2014 Cochrane reviewfound insufficient evidence to determine the effects of garlic in preventing or treating the common cold. Other reviews concluded a similar absence of high-quality evidence for garlic having a significant effect on the common cold.
The sticky juice within the bulb cloves is used as an adhesive in mending glass and porcelain.An environmentally benign garlic-derived polysulfide product is approved for use in the European Union (under Annex 1 of 91/414) and the UK as a nematicide and insecticide, including for use for control of cabbage root fly and red mite in poultry.
Garlic is known to cause bad breath (halitosis) and body odor, described as a pungent garlicky smell to sweat.This is caused by allyl methyl sulfide (AMS). AMS is a volatile liquid which is absorbed into the blood during the metabolism of garlic-derived sulfur compounds; from the blood it travels to the lungs (and from there to the mouth, causing bad breath; see garlic breath) and skin, where it is exuded through skin pores. Washing the skin with soap is only a partial and imperfect solution to the smell. Studies have shown sipping milk at the same time as consuming garlic can significantly neutralize bad breath. Mixing garlic with milk in the mouth before swallowing reduced the odor better than drinking milk afterward. Plain water, mushrooms, and basil may also reduce the odor; the mix of fat and water found in milk, however, was the most effective.
The green, dry "folds" in the center of the garlic clove are especially pungent. The sulfur compound allicin, produced by crushing or chewing fresh garlic,produces other sulfur compounds: ajoene, allyl polysulfides, and vinyldithiins. Aged garlic lacks allicin, but may have some activity due to the presence of S-allylcysteine.
Some people suffer from allergies to garlic and other species of Allium .Symptoms can include irritable bowel, diarrhea, mouth and throat ulcerations, nausea, breathing difficulties, and, in rare cases, anaphylaxis. Garlic-sensitive people show positive tests to diallyl disulfide, allylpropyldisulfide, allylmercaptan, and allicin, all of which are present in garlic. People who suffer from garlic allergies are often sensitive to many other plants, including onions, chives, leeks, shallots, garden lilies, ginger, and bananas.
Several reports of serious burns resulting from garlic being applied topically for various purposes, including naturopathic uses and acne treatment, indicate care must be taken for these uses, usually testing a small area of skin using a low concentration of garlic.On the basis of numerous reports of such burns, including burns to children, topical use of raw garlic, as well as insertion of raw garlic into body cavities, is discouraged. In particular, topical application of raw garlic to young children is not advisable.
The side effects of long-term garlic supplementation are largely unknown.Possible side effects include gastrointestinal discomfort, sweating, dizziness, allergic reactions, bleeding, and menstrual irregularities.
Some breastfeeding mothers have found, after consuming garlic, that their babies can be slow to feed, and have noted a garlic odor coming from them.
If higher-than-recommended doses of garlic are taken with anticoagulant medications, this can lead to a higher risk of bleeding.Garlic may interact with warfarin, saquinavir, antihypertensives, calcium channel blockers, the quinolone family of antibiotics such as ciprofloxacin, and hypoglycemic drugs, as well as other medications. Alliums might be toxic to cats or dogs.
In folklore, garlic has been regarded as a force for both good and evil. In Europe, many cultures have used garlic for protection or white magic, perhaps owing to its reputation in folk medicine.Central European folk beliefs considered garlic a powerful ward against demons, werewolves, and vampires. To ward off vampires, garlic could be worn, hung in windows, or rubbed on chimneys and keyholes.
In the foundation myth of the ancient Korean kingdom of Gojoseon, eating nothing but 20 cloves of garlic and a bundle of Korean mugwort for 100 days let a bear be transformed into a woman.
In celebration of Nowruz (Persian calendar New Year), garlic is one of the essential items in a Haft-sin ("seven things beginning with 'S'") table, a traditional New Year's display: the name for garlic in Persian is سیر (seer), which begins with "س" (sin, pronounced "seen") the Perso-Arabic letter corresponding to "S".
In Islam, it is recommended not to eat raw garlic prior to going to the mosque. This is based on several hadith.

In the typical serving size of 1–3 cloves (3–9 grams), garlic provides no significant nutritional value, with the content of all essential nutrients below 10% of the Daily Value (DV) (table).When expressed per 100 grams, garlic contains several nutrients in rich amounts (20% or more of the DV), including vitamins B6 and C, and the dietary minerals manganese and phosphorus. Per 100 gram serving, garlic is also a moderate source (10–19% DV) of certain B vitamins, including thiamin and pantothenic acid, as well as the dietary minerals calcium, iron, and zinc (table).
The composition of raw garlic is 59% water, 33% carbohydrates, 6% protein, 2% dietary fiber, and less than 1% fat.
Chives, scientific name Allium schoenoprasum, is a species of flowering plant in the family Amaryllidaceae that produces edible leaves and flowers. Their close relatives include the common onions, garlic, shallot, leek, scallion, and Chinese onion.
The shallot is a botanical variety of the onion. Until 2010, the shallot was classified as a separate species, Allium ascalonicum, a name that is a synonym of Allium cepa, the species name of the onion. A. cepa is the correct name for the shallot species.
The onion, also known as the bulb onion or common onion, is a vegetable that is the most widely cultivated species of the genus Allium. The shallot is a botanical variety of the onion. Until 2010, the shallot was classified as a separate species.
Allicin is an organosulfur compound obtained from garlic, a species in the family Alliaceae. It was first isolated and studied in the laboratory by Chester J. Cavallito and John Hays Bailey in 1944. When fresh garlic is chopped or crushed, the enzyme alliinase converts alliin into allicin, which is responsible for the aroma of fresh garlic. The allicin generated is unstable and quickly changes into a series of other sulfur-containing compounds such as diallyl disulfide. Allicin is part of a defense mechanism against attacks by pests on the garlic plant.
Scallions are vegetables derived from various species in the genus Allium. Scallions have a milder taste than most onions. Their close relatives include garlic, shallot, leek, chive, and Chinese onions.
Elephant garlic is a perennial plant belonging to the onion genus. It has a tall, solid, flowering stalk and broad, flat leaves. The flavor is milder than garlic, and much more palatable to some people than garlic when used raw as in salads. It is sometimes confused with solo garlic.
Ajoene is an organosulfur compound found in garlic extracts. It is a colorless liquid that contains sulfoxide and disulfide functional groups. The name is derived from "ajo", the Spanish word for garlic. It is found as a mixture of up to four stereoisomers, which differ in terms of the stereochemistry of the central alkene and the chirality of the sulfoxide sulfur.
Allium ampeloprasum is a member of the onion genus Allium. The wild plant is commonly known as wild leek or broadleaf wild leek. Its native range is southern Europe to western Asia, but it is cultivated in many other places and has become naturalized in many countries.
Solo garlic, also known as single clove garlic, monobulb garlic, single bulb garlic, or pearl garlic, is a type of Allium sativum (garlic). The size of the single clove differs from approximately 25 to 50 mm in diameter. It has the flavour of the garlic clove but is somewhat milder and slightly perfumed. The appearance is somewhat akin to that of a pickling onion, with white skin and often purple stripes. Solo garlic offers the advantage, compared to traditional garlic, of being very quick and easy to peel.
Diallyl disulfide is an organosulfur compound derived from garlic and a few other genus Allium plants. Along with diallyl trisulfide and diallyl tetrasulfide, it is one of the principal components of the distilled oil of garlic. It is a yellowish liquid which is insoluble in water and has a strong garlic odor. It is produced during the decomposition of allicin, which is released upon crushing garlic and other plants of the family Alliaceae. Diallyl disulfide has many of the health benefits of garlic, but it is also an allergen causing garlic allergy. Highly diluted, it is used as a flavoring in food. It decomposes in the human body into other compounds such as allyl methyl sulfide.
Garlic powder is a spice that is derived from dehydrated garlic and used in cooking for flavour enhancement. The process of making garlic powder includes drying and dehydrating the vegetable, then powdering it through machinery or home-based appliances depending on the scale of production. Garlic powder is a common component of spice mix. It is also a common component of seasoned salt.
Allium monanthum, the Korean wild chive, is a spring vegetable with minuscule bulbous roots that have a mild onion flavor and found in the woodlands of Korea, Japan, northeastern Russia (Primorye), and northeastern China.
In enzymology, an alliin lyase is an enzyme that catalyzes the chemical reaction
Black garlic is a type of aged garlic that is deeply colored brown. The color is a result of the Maillard reaction or caramelization, not fermentation. It was first used as a food ingredient in Asian cuisine. It is made by heating whole bulbs of garlic over the course of several weeks, a process that results in black cloves. The taste is sweet and syrupy with hints of balsamic vinegar or tamarind. Black garlic's popularity has spread around the world as it has become a sought-after ingredient used in both home-cooking and high-end cuisine.
Vinyldithiins, more precisely named 3-vinyl-4H-1,2-dithiin and 2-vinyl-4H-1,3-dithiin, are organosulfur phytochemicals formed in the breakdown of allicin from crushed garlic (Allium sativum). Vinyldithiins are Diels-Alder dimers of thioacrolein, H2C=CHCH=S, formed in turn by decomposition of allicin. In garlic supplements, vinyldithiins are only found in garlic oil macerates that are made by incubation of crushed garlic in oil.
Allium ochotense, the Siberian onion, is a primarily East Asian species of wild onion native to northern Japan, Korea, China, and the Russian Far East, as well as on Attu Island in Alaska.
Allium is a genus of monocotyledonous flowering plants that includes hundreds of species, including the cultivated onion, garlic, scallion, shallot, leek, and chives. The generic name Allium is the Latin word for garlic, and the type species for the genus is Allium sativum which means "cultivated garlic".
The leek is a vegetable, a cultivar of Allium ampeloprasum, the broadleaf wild leek. The edible part of the plant is a bundle of leaf sheaths that is sometimes erroneously called a stem or stalk. The genus Allium also contains the onion, garlic, shallot, scallion, chive, and Chinese onion. Three closely related vegetables, elephant garlic, kurrat and Persian leek or tareh, are also cultivars of A. ampeloprasum, although different in their uses as food.
Garlic oil is the volatile oil derived from garlic. It is usually prepared using steam distillation, and can also be produced via distillation using ether. It is used in cooking and as a seasoning, a nutritional supplement, and also as an insecticide.
You sow it in fall, not spring. The plant often forms strange curling stalks, or 'scapes', with odd nodules called umbels. These rococo growths contain their own minicloves called bulbils.
Garlic scapes are pencil thin and exuberantly loopy, and emanate a clean and mildly garlicky scent. … They had a gently spicy undertone and an exquisitely fresh green, mellow taste. Unlike regular garlic, which needs some kind of vehicle to carry its intense flavor to the mouth, scapes are self-sufficient; vegetable and aromatic all in one.
