Acid Resistant Konjac Micro
Acid Resistant Konjac Micro is a micron-particle konjac glucomannan that has been physically and chemically modified to resist viscosity loss in acidic systems below pH 4. The product retains the rapid cold-dispersion of standard micro flour while standing up to citric, malic, and lactic acid environments that would degrade conventional konjac.
Native konjac glucomannan is hydrolysed by acid at low pH, particularly when heated. The acid-resistant variant uses controlled cross-linking and selective fractionation to slow that hydrolysis without losing functional viscosity.
We source bulk Acid Resistant Konjac Micro 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
There are two principal specifications of Acid Resistant Konjac Micro.
The beverage grade is optimised for ready-to-drink products at pH 3.5 to 4.5, with viscosity retention above 80 percent after a 90-day shelf-life simulation.
The hot-fill grade is built for fruit-flavoured products that pass through a brief pasteurisation at 85 to 95 °C in acidic conditions, with viscosity retention above 70 percent after the heat step.
Both grades run at 200 to 300 mesh micron particle size for rapid cold dispersion.
Applications
- Acidic ready-to-drink fruit beverages and flavoured waters
- Sports drinks and isotonic beverages at low pH
- Acidified plant milks and dairy-alternative drinks
- Citrus-flavoured jelly cups and dessert pouches
- Vinegar-based dressings and condiments with hold-up texture
- Hot-fill fruit preparations for yogurt and ice cream
- Acidified pharmaceutical syrups and oral suspensions
- Sour confectionery jellies and gummies
- Marinades and acidic meat-injection brines
- Acid-stable cosmetic gels and serums

How We Help Source Acid Resistant Konjac Micro
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 Resistant Konjac Micro 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 Resistant Konjac Micro 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
The product is regulated as modified konjac gum in most jurisdictions.
It carries E425 designation in the European Union when the cross-linking reagent and residual levels conform to the additive specification. The U.S. FDA permits chemically modified konjac under the modified food starch and modified gum frameworks.
Halal, Kosher, vegan, non-GMO, and gluten-free certifications are routinely available. Mini-cup jelly format restrictions apply where legislated.
Manufacturing Process
Production starts from purified konjac gum at above 90 percent glucomannan content.
The gum is treated with a controlled cross-linking agent, typically sodium trimetaphosphate or a food-grade epoxide, under mild alkaline conditions. The cross-links reinforce the polymer backbone against acid hydrolysis.
After reaction, the modified gum is washed thoroughly to remove residual reagent and salts, then dried under vacuum to preserve molecular weight. The dried product is jet-milled to micron particle size and air-classified to the target distribution.
Quality control includes accelerated acid-stability testing, in which the product is held in pH 3.5 citric acid solution at 40 °C for one to two weeks and viscosity is measured.
