Xanthan Gum

Xanthan Gum is a high-molecular-weight extracellular polysaccharide produced by aerobic fermentation of the bacterium Xanthomonas campestris. It hydrates rapidly in cold or hot water and gives suspensions an unusually strong shear-thinning behaviour.

The chain is a cellulose-like β-1,4-D-glucose backbone carrying trisaccharide side groups built from mannose and glucuronic acid, with pyruvate and acetate substitutions. This rigid double-helical structure is what gives the gum its low-shear viscosity and weak-gel mouthfeel.

We source bulk Xanthan Gum from top China manufacturers for our partners, working with several of them. The manufacturers are mostly in Inner Mongolia, Hebei and Shandong. For this ingredient the minimum order is 1,000 kg and a 20-foot container takes 18 MT, and a smaller requirement can ship in a combined container with other ingredients.

Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades

Xanthan Gum is graded primarily by mesh size, pyruvate content, and end-use compliance.

80-mesh material is the standard grade for sauces, dressings, and bakery dough conditioning, where slower hydration is acceptable. 200-mesh and 200-mesh-fine grades are used in dry beverage mixes, instant soups, and gluten-free baking premixes that need rapid dispersion.

Transparent (clarified) grades are produced for clear beverages, ready-to-drink teas, and personal-care gels. Higher-pyruvate grades give stronger synergy with locust bean gum and are produced for elastic dessert gels.

Oilfield-grade xanthan is produced separately for drilling muds and enhanced oil recovery, with looser microbial and clarity specifications.

Applications

Salad dressings, vinaigrettes, and barbecue sauces for emulsion stability and cling
Gluten-free bread, cake, and pastry mixes as a structural binder replacing wheat gluten
Dairy beverages, plant milks, and protein drinks to suspend cocoa, calcium, and pulp particles
Instant soups, gravies, and dry sauce sachets for cold or hot reconstitution
Ice cream, sorbet, and frozen-dessert mixes for ice-crystal control and creamier texture
Toothpaste, mouthwash, and oral-care gels for binding and shear-thinning flow
Shampoos, body washes, and conditioner systems as a viscosifier and pearliser carrier
Pharmaceutical suspensions and pediatric syrups for active-ingredient suspension
Oil and gas drilling fluids for cuttings transport and filtration control
Pet food gravies and wet-pet-food coatings for cling and visual gloss

Brands Using Xanthan Gum

How We Help Source Xanthan Gum

Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Xanthan Gum out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Xanthan Gum together with other ingredients such as Carrageenan, Sodium Carboxymethyl Cellulose and Agar Agar into one 20' FCL. If your quantity is small, we can also ship LCL.

Regulatory Status

Xanthan Gum is approved as a food additive in all major markets and is one of the most widely cleared hydrocolloids in modern food law.

In the European Union Regulation (EC) No 1333/2008 lists it as E415, a permitted thickener and stabiliser. The U.S. Food and Drug Administration affirms it as GRAS under 21 CFR 172.695 for general food use.

JECFA has reviewed xanthan multiple times and considers the daily intake not to be of toxicological concern at typical use levels. The Joint FAO/WHO specification covers identity, purity, and residual isopropanol limits.

Halal and Kosher certificates are routinely available, and most major suppliers offer non-GMO and organic-compliant grades.

Manufacturing Process

Xanthan Gum Manufacturing Process

Loading process diagram…

Xanthan gum is made by submerged aerobic fermentation. A glucose- or sucrose-rich medium is inoculated with a selected strain of Xanthomonas campestris and held at around 28 to 32 °C with vigorous stirring and aeration for two to four days.

As biomass grows, the cells secrete xanthan into the broth. Viscosity climbs steadily and limits oxygen transfer, which is why fermenter geometry and impeller design are central to yield.

The broth is pasteurised to kill the producing organism, then the gum is precipitated by adding 2-3 volumes of isopropyl alcohol or ethanol. The fibrous precipitate is pressed, milled, dried, and screened to the target mesh.

Recovery solvent is distilled and recycled. Clarified grades involve an additional filtration of the heated broth before precipitation to remove cell debris.
