Acid Stable Konjac Gum
Acid Stable Konjac Gum is a high-purity konjac glucomannan, above 90 percent glucomannan content, that has been modified to maintain functional viscosity in low-pH beverage and food systems. It is the premium acid-resistant grade in the konjac portfolio.
Unlike the micron-particle variant, acid stable gum runs at standard 80 to 120 mesh and is intended for industrial users with adequate dispersion equipment and longer hydration windows.
We source bulk Acid Stable Konjac Gum from top China manufacturers for our partners. The manufacturer is in Hubei. 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
Acid Stable Konjac Gum divides into three viscosity classes.
The 28,000 cP grade is the standard for fruit beverage stabilisation and pulp suspension at pH 3.5 to 4.
The 32,000 cP grade serves higher-viscosity applications including acidified dairy and protein drinks.
The 36,000 cP premium grade is used in confectionery jellies and concentrated fruit preparations where maximum gel strength must be retained through acid exposure.
All three grades are produced with stability data showing viscosity retention after accelerated acid-aging tests at pH 3 and 40 °C.
Applications
- Acidified ready-to-drink fruit beverages requiring long shelf life
- Acidified dairy beverages and drinking yogurts
- Plant-based protein beverages in acidic flavour systems
- Sports drinks, electrolyte waters, and functional beverages
- Acidic ready-to-eat jelly cups and dessert pouches
- Fruit jams and preserves with extended shelf life
- Vinegar-based dressings and condiments
- Hot-fill fruit preparations for yogurt and ice cream
- Sour confectionery jellies and pâte de fruit
- Pharmaceutical syrups and oral suspensions at low pH

How We Help Source Acid Stable Konjac 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 Acid Stable Konjac 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 Acid Stable Konjac 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
Acid Stable Konjac Gum is regulated as a modified konjac gum.
It carries E425 designation in the European Union when reagent residuals conform to additive specifications. The U.S. FDA permits modified konjac under the modified gum framework.
Halal, Kosher, vegan, non-GMO, and gluten-free certifications are routinely available. Mini-cup jelly format restrictions apply where legislated.
Manufacturing Process
Production begins with the premium purified konjac gum at over 90 percent glucomannan.
The gum is reacted with a food-grade cross-linking agent, commonly sodium trimetaphosphate or propylene oxide, under controlled alkaline conditions. The reaction introduces covalent bridges between adjacent polymer chains, reinforcing the network against acid hydrolysis.
After reaction the modified gum is washed in alcohol to remove residual reagent, salts, and reaction by-products, then dried under vacuum to preserve molecular weight.
The dried gum is milled to 80 to 120 mesh and air-classified. Stability is verified by extended hold tests in pH 3 to 4 citric acid solution at elevated temperature.
