Xanthan gum solubility in water

Xanthan gum is a natural biopolymer produced by fermentation of sugar, dextrose, corn syrup or starch by Xanthomonas campestris. Xanthan gum is used as a stabilizer in many applications to provide excellent particulate suspension, emulsion stability, viscosity, moisture retention, and freeze-thaw stability.

Xanthan gum is soluble in both hot and cold water. The key advantages to using xanthan gum are that it imparts high viscosity solutions at low concentrations, it is stable over a wide range of pH levels and temperatures, and it is compatible with applications containing salt and enzymes.

Solutions of xanthan gum exhibit a pseudoplastic rheology; as shear forces are increased, the viscosity decreases and as shear forces are decreased, the apparent viscosity increases again. This characteristic is employed to suspend particles at rest and stabilize emulsions while promoting ease of pumping and pouring. Xanthan gum is synergistic with locust bean gum and tara gum to form thermo-reversible gels, and with guar gum to provide enhanced viscosity.

Xanthan — a fine mesh product with very rapid hydration making it suitable for dry mix formulations. Quik-Xan — an agglomerated product that provides a combination of easy dispersion, rapid hydration, and very low dust.

Product Range : Ingredients Solutions offers a broad range of xanthan gums. Suitable for cosmetic and personal care applications Applications : Salad dressings and sauces Beverages Desserts Batters Bakery mixes Dry mix beverages, gravies, desserts and seasoning mixes.It is an effective thickening agent and stabilizer to prevent ingredients from separating.

It can be produced from simple sugars using a fermentation process, and derives its name from the species of bacteria used, Xanthomonas campestris.

Xanthan gum derives its name from the species of bacteria used during the fermentation process, Xanthomonas campestris. In foods, xanthan gum is common in salad dressings and sauces. It helps to prevent oil separation by stabilizing the emulsionalthough it is not an emulsifier.

Xanthan gum also helps suspend solid particles, such as spices. Xanthan gum helps create the desired texture in many ice creams. Toothpaste often contains xanthan gum as a binder to keep the product uniform. Xanthan gum also helps thicken commercial egg substitutes made from egg whites, to replace the fat and emulsifiers found in yolks. It is also a preferred method of thickening liquids for those with swallowing disorders, since it does not change the color or flavor of foods or beverages at typical use levels.

In most foods it is used at concentrations of 0. Xanthan gum is used in wide range food products, such as sauces, dressings, meat and poultry products, bakery products, confectionery products, beverages, dairy products, others. In the oil industryxanthan gum is used in large quantities to thicken drilling mud.

Xanthan gum provides great "low end" rheology. When circulation stops, the solids remain suspended in the drilling fluid. The widespread use of horizontal drilling and the demand for good control of drilled solids has led to its expanded use.

It has been added to concrete poured underwater, to increase its viscosity and prevent washout. In cosmeticsxanthan gum is used to prepare water gels. The viscosity of xanthan gum solutions decreases with higher shear rates.

This is called shear thinning or pseudoplasticity. This means that a product subjected to shear, whether from mixing, shaking or chewing will thin. When the shear forces are removed, the food will thicken again. In salad dressing, the addition of xanthan gum makes it thick enough at rest in the bottle to keep the mixture fairly homogeneous, but the shear forces generated by shaking and pouring thins it, so it can be easily poured.

When it exits the bottle, the shear forces are removed and it thickens again, so it clings to the salad. The greater the ratio of xanthan gum added to a liquid, the thicker the liquid will become.

An emulsion can be formed with as little as 0.

A teaspoon of xanthan gum weighs about 2. To make a foam, 0. Larger amounts result in larger bubbles and denser foam. Egg white powder 0.At present, xanthan gum is the best biological gum in the world with an integration of thickening, suspension, emulsification and stability.

The number of pyruvic acid groups at the end of molecular side chain can have a great effect on its properties. Xanthan gum on one hand possesses the same general properties as long-chain polymers. On the other hand, it has more functional groups than the general polymers, so it displays some distinctive properties under certain conditions.

How to Disperse Gums in Water

Xanthan gum possesses a favorable suspension property as for insoluble solids and oil drops. The molecules of xanthan gum solution can form a banded spiral co-polymer and a fragile network structure like gum, and consequently it can support the forms of solid particle, liquid drops and air bubbles, and displays a strong emulsion stability property and a favarable suspension capacity. Xanthan gum can be quickly dissolved in water and thus possesses preferable water-solubility.

It is soluble even in cold water so it saves you from complicated processes and uses conveniently. Due to its strong hydrophilicity, however, make sure to use it properly. For example, if it is directly mixed with a small amount of water and not uniformly stirred, the outer sphere absorbs water, expands into a micelle, prevents water from entering into the inner sphere and hinders its effects. Xanthan gum should be prepared into solutions for use in a correct process.

Its dry powder should be greatly mixed with such auxiliary materials in dray powder as salt or sugar and then slowly add water that is being stirred. Pseudoplastic property. Xanthan gum solution has high viscosity a static or low shear rate. Furthermore, when the shearing action is removed, it will immediately restore to its original viscosity. The relation between viscosity and shearing action is absolutely plastic.

The pseudoplastic property of xanthan gum is remarkable and plays a very important role in stabilizing suspension and emulsion.

Preferable water-solubility Xanthan gum can be quickly dissolved in water and thus possesses preferable water-solubility.That's a question a salad dressing manufacturer asked when he called our technical support hotline recently and it's a common question in the food industry. Whether you call them lumps, clumps, or fish-eyes, they've caused many headaches for food manufacturers.

The pesky lumps can create obvious problems like clogged filters in production tanks or less obvious problems downstream like inconsistent viscosity in the finished product.

If you are having difficulty with undissolved gum, the solution likely requires making only a few minor changes to the first steps in your production process. Gums begin to hydrate nearly as soon as they are added to water and sometimes hydration occurs before the gum is fully dispersed. This can result in the formation of gum balls or lumps that have dry gum powder on the inside where the water couldn't penetrate.

While all powdered gums have a tendency to form lumps when added to water, some gums are more troublesome than others. These gums are prone to lumping because their hygroscopic nature means they more readily attract and hold water molecules. When dissolving any gum in water keep in mind that the most important time for the gum is the first three minutes after addition or production. Giving the gum 5 to 10 minutes to hydrate makes a dramatic difference in the level of gum needed and in the functional properties it exhibits.Guar gumalso called guaranis 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.

The guar bean is principally grown in IndiaPakistanU. India produces about 2. The US has produced 4, to 14, tonnes of guar over the last 5 years. Chemically, guar gum is an exo- polysaccharide composed of the sugars galactose and mannose. Guar gum is more soluble than locust bean gum due to its extra galactose branch points.

Unlike locust bean gum, it is not self-gelling. In water, it is nonionic and hydrocolloidal. It is not affected by ionic strength or pHbut will degrade at extreme pH and temperature e.

Strong acids cause hydrolysis and loss of viscosity and alkalies in strong concentration also tend to reduce viscosity. It is insoluble in most hydrocarbon solvents.

The viscosity attained is dependent on time, temperature, concentration, pH, rate of agitation and particle size of the powdered gum used. The lower the temperature, the lower the rate at which viscosity increases, and the lower the final viscosity. Finer guar powders swell more rapidly than larger particle size coarse powdered gum. Guar gum shows a clear low shear plateau on the flow curve and is strongly shear-thinning.

The rheology of guar gum is typical for a random coil polymer. It does not show the very high low shear plateau viscosities seen with more rigid polymer chains such as xanthan gum. Guar gum shows viscosity synergy with xanthan gum. Guar gum and micellar casein mixtures can be slightly thixotropic if a biphase system forms.

One use of guar gum is a thickening agent in foods and medicines for humans and animals. Because it is gluten-free, it is used as an additive to replace wheat flour in baked goods.

It has been shown to reduce serum cholesterol and lower blood glucose levels. Guar gum is economical as well. Because it has almost eight times the water-thickening ability of other agents e. In addition to guar gum's effects on viscosity, its high ability to flow, or deformgives it favorable rheological [ clarification needed ] properties. It forms breakable [ clarification needed ] gels when cross-linked with boron.

Water alone is too thin to be effective at carrying proppant sand, so guar gum is one of the ingredients added to thicken the slurry mixture and improve its ability to carry proppant.

There are several properties which are important 1. Thixotropic: the fluid should be thixotropic, meaning it should gel within a few hours. Gelling and de-gelling: The desired viscosity changes over the course of a few hours.Your wishlist has been temporarily saved.

How to Mix Xanthan Gum

Xanthan Gum is used as a food additive, and in cosmetics, as a thickener or rheology modifier and emulsion stabilizer. Our Xanthan Gum Clear is a higher purity, cosmetic grade made without hydration retardants for quicker thickening. It produces the clearest gels. Our Xanthan Gum Clear in solution with have greater viscosity and clarity than our Xanthan Gum Soft, but with more stringing effect. Xanthan gum produces a large increase in the viscosity of a liquid with the addition of a very small amount of gum.

Xanthan Gum is an excellent natural source thickener for lotions, creams, liquid soap, shower gels, body washes and shampoos. To incorporate without agglomeration, create a vortex in the water with your mixer paddle, stick blender, etc.

Alternately, the xanthan gum can be pre-dispersed in glycerin or propylene glycol and then immediately added to the water phase with mixing. Once the xanthan gum is fully hydrated, the resulting solution can be heated if necessary for the inclusion of other ingredients.

Home Xanthan Gum Clear Click or scroll to zoom.I confess — having to use a powdery ingredient that gets readily lumpy in my formulations is a nightmare for me. The real horror starts when you try to make a transparent gel, where every smallish lump is visible.

I started to use this method as an alternative to method 1. It is not bad, but you really need to know how much of water to add. Too little or too much too fast will result in a big lump difficult to dissolve. And again, you need to stir, stir and stir… which again is not an option when you have surfactants in your formulation.

I was inspecting the ingredients and remarked them using glycerin. The problem is that xanthan gum or guar gum or any other thickening gum starts to swell in contact with water.

If you are not fast or cautious enough, lumps create as the particles are being trapped in the gel. If you have oil in your formulation, dissolve xanthan gum it the oil phase. If you do not have oil, use small amount of glycerin. This entry was posted by evik on September 24, atand is filed under about ingredientscosmetics making.

You can leave a response or trackback from your own site. I tried Xanthan gum twice — with an aim to thicken my homemade soap — disaster both times. I really did NOT enjoy working with this. I may attempt your method…. Really enjoyed reading this. Very informative. Great article, and I totally agree with you. Thanks for being so thorough and sharing your fails and successes, it shows your passion and expertise. I have a question. In making a shampoo without water, the main ingredient is liquid castile, and two lesser ingredients are aloe gel, and vegetable glycerin.

Do I mix the xanthan with the glycerin, then add that mixture, at the end, once all else is mixed? Your insight would be greatly appreciated. Thank you. Hi Annabelle, I believe the best would be if you used only salt for thickening your castille soap — use about 1 teaspoon to 8 oz of soap. Let it dissolve without stirring and then stir it in. If you need thicker product, add more salt. I never had success with Xanthan gum in thickening liquid soap.

It only gels in water, so it really depends how much of water your soap contains. Also — it is not that good in thickening high alkaline products, it is incompatible with metal ions. Every time I finished having part of it sinked to the bottom….
