Capsaicinoids
Capsaicin (8-methyl-''N''-vanillyl-6-nonenamide) ( or ) is an active component of chili peppers, which are plants belonging to the genus ''Capsicum''. It is a chemical irritant for mammals, including humans, and produces a sensation of burning in any tissue with which it comes into contact. Capsaicin and several related alkaloids are called capsaicinoids and are produced as secondary metabolites by chili peppers, probably as deterrents against certain mammals and fungi.What Made Chili Peppers So Spicy?

Scoville Scale
The Scoville scale is a measurement of the pungency (spiciness or "heat") of chili peppers, as recorded in Scoville heat units (SHU), based on the concentration of capsaicinoids, among which capsaicin is the predominant component. The scale is named after its creator, American pharmacist Wilbur Scoville, whose 1912 method is known as the Scoville organoleptic test. The Scoville organoleptic test is a subjective assessment derived from the capsaicinoid sensitivity by people experienced with eating hot chilis. An alternative method, high-performance liquid chromatography (HPLC), can be used to analytically quantify the capsaicinoid content as an indicator of pungency. As of 2011, the subjective organoleptic test has been largely superseded by analytical methods such as HPLC. Scoville organoleptic test In the Scoville organoleptic test, an exact weight of dried pepper is dissolved in alcohol to extract the heat components (capsaicinoids), then diluted in a solution of sugar wa ...

Chili Pepper
Chili peppers (also chile, chile pepper, chilli pepper, or chilli), from Nahuatl '' chīlli'' (), are varieties of the berry-fruit of plants from the genus ''Capsicum'', which are members of the nightshade family Solanaceae, cultivated for their pungency. Chili peppers are widely used in many cuisines as a spice to add "heat" to dishes. Capsaicin and related compounds known as capsaicinoids are the substances giving chili peppers their intensity when ingested or applied topically. While ''chili peppers'' are (to varying degrees) pungent or "spicy", there are other varieties of capsicum such as bell peppers (UK: peppers) which generally provide additional sweetness and flavor to a meal rather than “heat.” Chili peppers are believed to have originated somewhere in Central or South America. and were first cultivated in Mexico. After the Columbian Exchange, many cultivars of chili pepper spread around the world, used for both food and traditional medicine. This led to a ...

Hot Sauce
Hot sauce is a type of condiment, seasoning, or salsa made from chili peppers and other ingredients. Many commercial varieties of mass-produced hot sauce exist. History Humans have used chili peppers and other hot spices for thousands of years. Inhabitants of Mexico, Central America and South America had chili peppers more than 6,000 years ago. Within decades of contact with Spain and Portugal in the 16th century, the New World plant was carried across Europe and into Africa and Asia, and altered through selective breeding. One of the first commercially available bottled hot sauces in America appeared in 1807 in Massachusetts. Few of the early brands from the 1800s survived to this day, however. Tabasco sauce is the earliest recognizable brand in the United States hot sauce industry, appearing in 1868. As of 2010, it was the 13th best-selling seasoning in the United States preceded by Frank's RedHot Sauce in 12th place, which was the sauce first used to create buffalo wings. In ...

Diethyl Ether
Diethyl ether, or simply ether, is an organic compound in the ether class with the formula , sometimes abbreviated as (see Pseudoelement symbols). It is a colourless, highly volatile, sweet-smelling ("ethereal odour"), extremely flammable liquid. It is commonly used as a solvent in laboratories and as a starting fluid for some engines. It was formerly used as a general anesthetic, until non-flammable drugs were developed, such as halothane. It has been used as a recreational drug to cause intoxication. Production Most diethyl ether is produced as a byproduct of the vapor-phase hydration of ethylene to make ethanol. This process uses solid-supported phosphoric acid catalysts and can be adjusted to make more ether if the need arises. Vapor-phase dehydration of ethanol over some alumina catalysts can give diethyl ether yields of up to 95%. Diethyl ether can be prepared both in laboratories and on an industrial scale by the acid ether synthesis. Ethanol is mixed with a stro ...

Fungicide
Fungicides are biocidal chemical compounds or biological organisms used to kill parasitic fungi or their spores. A fungistatic inhibits their growth. Fungi can cause serious damage in agriculture, resulting in critical losses of yield, quality, and profit. Fungicides are used both in agriculture and to fight fungal infections in animals. Chemicals used to control oomycetes, which are not fungi, are also referred to as fungicides, as oomycetes use the same mechanisms as fungi to infect plants. Fungicides can either be contact, translaminar or systemic. Contact fungicides are not taken up into the plant tissue and protect only the plant where the spray is deposited. Translaminar fungicides redistribute the fungicide from the upper, sprayed leaf surface to the lower, unsprayed surface. Systemic fungicides are taken up and redistributed through the xylem vessels. Few fungicides move to all parts of a plant. Some are locally systemic, and some move upwardly. Most fungicides that can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salsa (sauce)
Salsa is a variety of sauces used as condiments for tacos and other Mexican and Mexican-American foods, and as dips for tortilla chips. They may be raw or cooked, and are generally served at room temperature. Though the word ''salsa'' means any kind of sauce in Spanish, in English, it refers specifically to these Mexican table sauces, especially to the chunky tomato-and- chili-based pico de gallo, as well as to salsa verde. chips and dip, Tortilla chips with salsa are a ubiquitous appetizer in Mexican-American restaurants, but not in Mexico itself. History The use of salsa as a table dip was first popularized by Mexican restaurants in the United States. In the 1980s, tomato-based Mexican-style salsas gained in popularity. In 1992, the dollar value of salsa sales in the United States exceeded those of tomato ketchup. Tomato-based salsas later found competition from salsas made with fruit, corn, or black turtle bean, black beans. Since the 2000s sweet salsas combining fruits ...

Tabasco Sauce
Tabasco is an American brand of hot sauce made from vinegar, tabasco peppers (''Capsicum frutescens'' var. ''tabasco''), and salt. It is produced by McIlhenny Company of Avery Island in south Louisiana, having been created over 150 years ago by Edmund McIlhenny. Although tabasco peppers were initially grown only on Avery Island, they are now primarily cultivated in Central America, South America and Africa. The Tabasco sauce brand also has multiple varieties including the original red sauce, habanero, chipotle, sriracha and Trinidad Moruga scorpion. Tabasco products are available in more than 195 countries and territories, and packaged in 36 languages and dialects. History According to the company's official history, Tabasco was first produced in 1868 by Edmund McIlhenny, a Maryland-born former banker who moved to Louisiana around 1840. However, as Jeffrey Rothfeder's book ''McIlhenny's Gold'' points out, some of the McIlhenny Company's official history is disputed, and that ...

Paprika
Paprika ( US , ; UK , ) is a spice made from dried and ground red peppers. It is traditionally made from ''Capsicum annuum'' varietals in the Longum group, which also includes chili peppers, but the peppers used for paprika tend to be milder and have thinner flesh. In some languages, but not English, the word ''paprika'' also refers to the plant and the fruit from which the spice is made, as well as to peppers in the Grossum group (e.g. bell peppers). All capsicum varieties are descended from wild ancestors in North America, in particular Central Mexico, where they have been cultivated for centuries. The peppers were subsequently introduced to the Old World, when peppers were brought to Spain in the 16th century. The seasoning is used to add color and flavor to many types of dishes in diverse cuisines. The trade in paprika expanded from the Iberian Peninsula to Africa and Asia and ultimately reached Central Europe through the Balkans, which was then under Ottoman rule. This he ...

Chili Powder
Chili powder (also spelled chile, chilli, or, alternatively, powdered chili) is the dried, pulverized fruit of one or more varieties of chili pepper, sometimes with the addition of other spices (in which case it is also sometimes known as chili powder blend or chili seasoning mix). It is used as a spice (or spice blend) to add pungency (piquancy) and flavor to culinary dishes. In American English, the spelling is usually "chili"; in British English, "chilli" (with two "l"s) is used consistently. Chili powder is used in many different cuisines, including American (particularly Tex-Mex), Chinese, Indian, Bangladeshi, Korean, Mexican, Portuguese, and Thai. A chili powder blend is the primary flavor in American chili con carne. Varieties Chili powder is sometimes known by the specific type of chili pepper used. Varieties of chili peppers used to make chili powder include Aleppo, ancho, cayenne, chipotle, chile de árbol, jalapeño, New Mexico, pasilla, and piri piri chili peppers ...

Spices
A spice is a seed, fruit, root, Bark (botany), bark, or other plant substance primarily used for flavoring or coloring food. Spices are distinguished from herbs, which are the leaves, flowers, or stems of plants used for flavoring or as a garnish (food), garnish. Spices are sometimes used in medicine, Sacred rite, religious rituals, cosmetics or perfume production. For example, vanilla is commonly used as an ingredient in Aroma compound, fragrance manufacturing. A spice may be available in several forms: fresh, whole dried, or pre-ground dried. Generally, spices are dried. Spices may be ground into a powder for convenience. A whole dried spice has the longest shelf life, so it can be purchased and stored in larger amounts, making it cheaper on a per-serving basis. A fresh spice, such as ginger, is usually more flavorful than its dried form, but fresh spices are more expensive and have a much shorter shelf life. Some spices are not always available either fresh or whole, for exam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mucous Membranes
A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. It is mostly of endodermal origin and is continuous with the skin at body openings such as the eyes, eyelids, ears, inside the nose, inside the mouth, lips, the genital areas, the urethral opening and the anus. Some mucous membranes secrete mucus, a thick protective fluid. The function of the membrane is to stop pathogens and dirt from entering the body and to prevent bodily tissues from becoming dehydrated. Structure The mucosa is composed of one or more layers of epithelial cells that secrete mucus, and an underlying lamina propria of loose connective tissue. The type of cells and type of mucus secreted vary from organ to organ and each can differ along a given tract. Mucous membranes line the digestive, respiratory and reproductive tract ...
