Guar gum

 

Guar gum, guar gum, Guara, (Е412) — a dietary Supplement refers to a group of stabilizers, thickeners, emulsifiers (E400-Е499), used in food industry as a thickener, contributing to the increase in viscosity.

At chemical composition like guar gum carob (food additive E410). Is a polymer compound containing residues of galactose. Substance have enough stiffness and high elasticity, soluble in water. Because of these properties was deemed very effective emulsifier and stabilizer. When cycles of freezing and thawing products guar gum has good resistance, prevents the appearance of ice crystals forming a structured gel.

Guar the gum is obtained by extraction from seeds of the plant Cyamopsis tetraganoloba — legumes, known as guar, or pea-tree, which grown mainly in India and Pakistan. Additionally, the guar resin produce in the US, Africa, Canada and Australia.

Application the food industry

Guar gum (viscosity 5000 3500 GPa and GPa in the standard solution) as a stabilizer consistency, increases the viscosity and gelling properties.

Substance soluble in cold water, compatible with most other vegetable hydrocolloids, such as agar-agar, carrageenan, gum carob wood, pectin, methylcellulose, and others, to improve consistency, such combinations can have a mutually positive impact. On the food industry comes in the form of ground powder with a pale white shade.

Considered that it is practically not absorbed in the intestine, reduces of appetite and very effectively reduces the level of cholesterol and saturated fat the body.

Used in the manufacture of sauces, yogurts, ice cream.

Guar resin refers to polysaccharides and is fairly soluble substance. The chemical composition of guar gum is similar to gum carob wood (food additive E410). It is a polymer compound, which contains residues of galactose. This guaran quite tough and it has a high elasticity and solubility in water. Thanks to this Supplement Е412 is considered a very good emulsifier and stabilizer. Also this Supplement shows good stability in a cycle of freezing and thawing products.

This Supplement it reduces appetite and effectively reduces elevated levels of saturated fats and of cholesterol in the body. Guar gum also helps to remove from the intestines toxins and harmful bacteria, increases absorption of calcium by the body. Used in the diets, helping to provide a feeling of satiety the body. Quite often Е412 additive is added to diabetic drugs to slow the absorption of sugar in the intestines.

Application guar gum in oil drilling industry

When use during oil drilling guar gum prevents water loss from viscous drilling mud and well suspenseful bentonite the clay used in drilling mud.

Guar gum is cheaper than most other thickeners in the drilling mud, however less thermally stable than xanthan gum at temperatures above 100 degrees C. In a large extent, this limitation can be overcome when using it hydroxypropionic derivatives that are more thermostable.

For enhance oil production through hydraulic fracturing in a borehole injected under pressure wedging means, e.g. sand, suspension in thickened with guar or hydroxypropylamino solution, with the aim the creation and expansion of cracks in rocks and provide seepage oil/gas well.

Due cross-linking with borate ions or transition metals, Zr and Ti often occurs gelatinization in situ injected guar gum. After completion of the hydraulic fracturing gel destroy and wash, and after the destruction is minimal amount of it. Application in the field oil production is one of the major applications for guar gum.

Other areas applications of guar gum

• Textile industry;

• Paper industry;

• Explosives manufacturing;

• Cosmetic industry;

• The coal industry.

Guar the gum is Packed in multilayer paper bags of 25 kg. Storage of guar gum is carried out in a dry warehouse in undamaged packaging.
