Konjac Gum
Konjac Gum is the purified glucomannan fraction of Amorphophallus konjac corm flour, with glucomannan content above 85 percent and minimal residual starch, fibre, and protein. It is the premium konjac hydrocolloid grade and the form recognised under the E425 food-additive number.
The polymer is a linear β-1,4-linked mannose-glucose backbone with intermittent acetyl substitution. It is the highest-molecular-weight commercial polysaccharide, which gives it unmatched viscosity-per-cost in cold-water applications.
We source bulk Konjac Gum from top China manufacturers for our partners, working with several of them. The manufacturers are mostly in Guangdong, Hubei and Sichuan. For this ingredient the minimum order is 500 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
Konjac Gum is graded by glucomannan content, viscosity, and mesh size.
Standard food-grade konjac gum runs 85 to 90 percent glucomannan with viscosity of 25 to 35 thousand cP at 1 percent. It is used in dairy, dessert, and meat-product applications.
Premium gum at 90 to 95 percent glucomannan and viscosity above 35 thousand cP is produced for clear beverage, confectionery, and pharmaceutical use.
Mesh sizes range from 80 to 200, with finer mesh for fast hydration in cold systems and coarser mesh for slow controlled hydration in hot processes.
Specialty acid-stable, high-transparency, and rapid-dispersing variants are sold under their own product specifications.
Applications
- Synergistic gel systems with xanthan and carrageenan in dessert and meat products
- Plant-based meat analogues as a binder and gel-network former
- Dairy and dairy-alternative beverages for body and suspension
- Bakery: gluten-free formulations and bread improvers
- Confectionery jellies and Asian-style konjac jelly products
- Dietary fibre supplements at higher purity than crude flour
- Sauces, dressings, and processed-meat binders
- Pharmaceutical bulk laxatives and weight-management products
- Cosmetic gels and natural-positioning thickeners
- Edible films and coatings for fresh produce

How We Help Source 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 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 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
Konjac Gum is approved as a food additive in most regulated markets.
Regulation (EC) No 1333/2008 lists it in the European Union as E425(i) konjac gum and E425(ii) konjac glucomannan. Mini-cup jelly confectionery use is restricted.
The U.S. FDA permits konjac gum as GRAS with mini-cup format restrictions. JECFA has assigned ADI not specified.
Halal, Kosher, vegan, non-GMO, organic, and gluten-free certifications are routinely available.
Manufacturing Process
Production starts from refined konjac flour, which is repeatedly washed in 50 to 70 percent ethanol. Each wash swells the residual starch, sugar, and salt impurities while leaving the glucomannan particles intact.
The slurry is filtered, fresh ethanol is added, and the cycle is repeated three to five times. The progressively cleaner gum is then dried under vacuum to preserve viscosity.
The dried gum is milled and air-classified to the target mesh. Quality control verifies glucomannan content, viscosity, residual ethanol, and microbial counts before release.
Yunnan, Sichuan, and Hubei in China dominate the supply of premium konjac gum. Japan operates several high-end refining lines for domestic pharmaceutical and confectionery use.
