Guar
The guar or cluster bean, with the botanical name ''Cyamopsis tetragonoloba'', is an annual legume and the source of guar gum. It is also known as gavar, gawar, or guvar bean. The origin of ''Cyamopsis tetragonoloba'' is unknown, since it has never been found in the wild.Whistler R.L. and Hymowitz T. 1979. Guar: agronomy, production, industrial use and nutrition. Purdue University Press, West Lafayette It is assumed to have developed from the African species ''Cyamopsis senegalensis''. It was further domesticated in South Asia, where it has been cultivated for centuries. Guar grows well in semiarid areas, but frequent rainfall is necessary. This legume is a valuable plant in a crop rotation cycle, as it lives in symbiosis with nitrogen-fixing bacteria.Undersander D.J., Putnam D.H., Kaminski A.R., Doll J.D., Oblinger E.S. and Gunsolus J.L. 1991.

Guar Gum
Guar gum, also called guaran, is a galactomannan polysaccharide extracted from guar beans that has thickening and stabilizing properties useful in food, feed, and industrial applications. The guar seeds are mechanically dehusked, hydrated, milled and screened according to application. It is typically produced as a free-flowing, off-white powder. Production and trade The guar bean is principally grown in India, Pakistan, the United States, Australia and Africa. India is the largest producer, accounting for nearly 80% of the world production. In India, Rajasthan, Gujarat, and Haryana are the main producing regions. The US has produced 4,600 to 14,000 tonnes of guar over the last 5 years. Texas acreage since 1999 has fluctuated from about 7,000 to 50,000 acres. The world production for guar gum and its derivatives is about 1.0 million tonnes. Non-food guar gum accounts for about 40% of the total demand. Properties Chemical composition Chemically, guar gum is an exo- polysacc ...

Galactomannan
Galactomannans are polysaccharides consisting of a mannose backbone with galactose side groups, more specifically, a (1-4)-linked beta-D-mannopyranose backbone with branchpoints from their 6-positions linked to alpha-D-galactose, (i.e. 1-6-linked alpha-D-galactopyranose). In order of increasing number of mannose-to-galactose ratio: *fenugreek, fenugreek gum, mannose:galactose ~1:1 *guar gum, mannose:galactose ~2:1 *tara gum, mannose:galactose ~3:1 *locust bean gum or ''carob gum'', mannose:galactose ~4:1 *cassia gum, mannose:galactose ~5:1 Galactomannans are often used in food products to increase the viscosity of the water phase. Guar gum has been used to add viscosity to artificial tears, but is not as stable as Carboxymethyl cellulose, carboxymethylcellulose. Food use Galactomannans are used in foods as stabilizer (chemistry), stabilisers. Guar and locust bean gum (LBG) are commonly used in ice cream to improve texture and reduce ice cream meltdown. LBG is also used extensiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slime (toy)
Slime was a toy product manufactured by Mattel, sold in a plastic trash can and introduced in February 1976. It consisted of a non-toxic viscous, squishy and oozy green or other color material made primarily from guar gum. Different variations of Slime were released over the years, including Slime containing rubber insects, eyeballs, and worms. The late 1970s also introduced a Slime Monster board game; the object of the game was to avoid having your game piece slimed on by a foot-tall plastic monster that had slime oozing from its mouth. Other toy companies have produced their own slime such as Hordak's Slime Pit playset as part of the ''Masters of the Universe'' toys in the 1980s, and Ecto-Plazm play gel sold with selected figures in Kenner's '' Real Ghostbusters'' toy line. Playmates Toys' Teenage Mutant Ninja Turtles figure line also had Retro-mutagen slime sold in containers and included with playsets. While the substance was considered non-toxic, it was extremely diffi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extractivism
Extractivism is the process of extracting natural resources from the Earth to sell on the world market. It exists in an economy that depends primarily on the extraction or removal of natural resources that are considered valuable for exportation worldwide. Some examples of resources that are obtained through extraction include gold, diamonds, lumber and oil. This economic model has become popular in many Latin American countries but is becoming increasingly prominent in other regions as well. Many factors are involved in the process of extractivism. These include but are not limited to community members, transnational corporations (TNCs) and the government. Trends have demonstrated that countries do not often extract their own resources; extraction is often led from abroad. These interactions have contributed to extractivism being rooted in the hegemonic order of global capitalism. Extractivism is controversial because it exists at the intersection where economic growth and environ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prebiotic (nutrition)
Prebiotics are compounds in food that induce the growth or activity of beneficial microorganisms such as bacteria and fungi. The most common example is in the gastrointestinal tract, where prebiotics can alter the composition of organisms in the gut microbiome. Dietary prebiotics are typically nondigestible fiber compounds that pass undigested through the upper part of the gastrointestinal tract and stimulate the growth or activity of advantageous bacteria in the colon by acting as substrates for them. They were first identified and named by Marcel Roberfroid in 1995. Depending on the jurisdiction, they may have regulatory scrutiny as food additives for the health claims made for marketing purposes. Common prebiotics used in food manufacturing include beta-glucan from oats and inulin from chicory root. Definition The definition of prebiotics and the food ingredients that can fall under this classification, has evolved since its first definition in 1995. In its earliest defi ...

Polysaccharide
Polysaccharides (), or polycarbohydrates, are the most abundant carbohydrates found in food. They are long chain polymeric carbohydrates composed of monosaccharide units bound together by glycosidic linkages. This carbohydrate can react with water (hydrolysis) using amylase enzymes as catalyst, which produces constituent sugars (monosaccharides, or oligosaccharides). They range in structure from linear to highly branched. Examples include storage polysaccharides such as starch, glycogen and galactogen and structural polysaccharides such as cellulose and chitin. Polysaccharides are often quite heterogeneous, containing slight modifications of the repeating unit. Depending on the structure, these macromolecules can have distinct properties from their monosaccharide building blocks. They may be amorphous or even insoluble in water. When all the monosaccharides in a polysaccharide are the same type, the polysaccharide is called a homopolysaccharide or homoglycan, but when more t ...

Molecular Weight
A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion. In quantum physics, organic chemistry, and biochemistry, the distinction from ions is dropped and ''molecule'' is often used when referring to polyatomic ions. A molecule may be homonuclear, that is, it consists of atoms of one chemical element, e.g. two atoms in the oxygen molecule (O2); or it may be heteronuclear, a chemical compound composed of more than one element, e.g. water (two hydrogen atoms and one oxygen atom; H2O). In the kinetic theory of gases, the term ''molecule'' is often used for any gaseous particle regardless of its composition. This relaxes the requirement that a molecule contains two or more atoms, since the noble gases are individual atoms. Atoms and complexes connected by non-covalent interactions, such as hydrogen bonds or ionic bonds, are typically not consi ...

Forage
Forage is a plant material (mainly plant leaves and stems) eaten by grazing livestock. Historically, the term ''forage'' has meant only plants eaten by the animals directly as pasture, crop residue, or immature cereal crops, but it is also used more loosely to include similar plants cut for fodder and carried to the animals, especially as hay or silage. While the term ''forage'' has a broad definition, the term ''forage crop'' is used to define crops, annual or biennial, which are grown to be utilized by grazing or harvesting as a whole crop. Common forages Grasses Grass forages include: *'' Agrostis'' spp. – bentgrasses **''Agrostis capillaris'' – common bentgrass **''Agrostis stolonifera'' – creeping bentgrass *''Andropogon hallii'' – sand bluestem *''Arrhenatherum elatius'' – false oat-grass *'' Bothriochloa bladhii'' – Australian bluestem *''Bothriochloa pertusa'' – hurricane grass *''Brachiaria decumbens'' – Surinam grass *''Brachiaria humidicola'' – ...
