Guar gum research paper

Guar is an annual legume that grows mainly in arid and semi-arid regions. In the past, this has led to large variations in annual availability, mainly due to weather conditions.

This has led to agronomy programmes with guar in other parts of the world, particularly the southern hemisphere Wielinga The production process for guar gum is simple. The guar seeds are milled to split them guar splits and remove the hull; the guar splits are then hydrated and milled to a powder.

The milled powder fractions are blended to meet the specifications, particularly Guar gum research paper size distribution and viscosity.

Purity is also important as gum products may contain residual hull and germ; hence protein content and acid insoluble residue an indication of the residual hull content are also specified.

The very simple production process makes guar gum an ideal candidate for natural hydrocolloid status. D-Galactose side chains are linked to the mannose units by 1,6-linkages.

Guar gum has a mannose: The more highly substituted structure does not leave any long unsubstituted regions, as seen in LBG, so guar gum cannot interact synergistically with other hydrocolloids to form gel structures. Some weaker synergy is seen with xanthan gum, resulting in a viscosity increase, but not gelling.

Enzymes can be used to remove some galactose residues, so that guar gum mimics the behaviour of LBG in terms of its gelling behaviour with xanthan or carrageenan. Guar gum is a cold water soluble, non-ionic hydrocolloid. It is an efficient and cost-effective thickening agent.

Guar Research

Because of its relatively cheap cost in use, it has been widely used in the food industry as a thickener, often to extend the use of more expensive hydrocolloids such as xanthan. However, the cost of guar gum is currently increasing — believed to be due to its high demand for use in oil drilling applications Food Navigator Guar gum solutions show good stability to most food processing operations and recipes, having good thermal stability, but are less stable at low pH.

Guar gum is widely used as a thickening, stabilising and suspending agent in drinks, sauces, soups, ketchups and mayonnaises. Its cold solubility and excellent freeze—thaw stability makes it popular in cold-prepared frozen foods.

Like LBG, it is often used in ice cream to provide smooth meltdown and reduce thermal shock.

Guar gum is used to control viscosity during processing e. While many of the hydrocolloids discussed in this chapter are classed as a soluble fibre and believed to have some other health benefits, guar gum has been scientifically established to maintain normal blood cholesterol concentrations. Since the key property of guar gum is its high viscosity at low concentrations, including high concentrations of guar gum in a food product will inevitably have a significant effect on the texture, and will limit the types of food products that can incorporate the guar gum.

However, there are low viscosity versions of guar gum available, which will be ideal for these applications.Guar Gum Market size will witness healthy growth with applications in textile, paper, food & beverage, explosives, pharmaceutical, cosmetics and oil & gas industries.

These are used in oil & gas industry for hydraulic fracturing in shale oil & gas extraction and consume around 90% of . The purpose of the present study was the development and in vitro/in vivo evaluation of the guar gum-based colon-specific compression-coated tablet formulation of theophylline, which can be used for the treatment of nocturnal asthma.

Guar gum. Guar gum is a galactommanan polysaccharide comprised of a chain of mannose units (1–4 linked β-D-mannopyranose) with galactose side groups (1–6 linked α-D-galactopyranose).

Paper Industry: Guar gum is used as a wet-end additive. It gives denser surface to the paper used for printing. It is also useful in foresheet formation, Mullen bursting strength, fold strength, tensile strength, measure of the force required, to pull a fiber from the surface of sheet, machine speed that all parameters are increased and.

Oct 04,  · Guar gum is a novel agrochemical processed from endosperm of cluster bean. It is largely used in the form of guar gum powder as an additive in food, pharmaceuticals, paper, textile, explosive, oil well drilling and cosmetics industry.

Guar gum is used as a wet-end strength additive in the pulp and paper industry to improve the physical properties of paper. It is used as a settling agent in the mining industry to speed up the settling of suspended particles.
