Product overview

What is food grade Konjac Gum?

Food grade konjac gum is a glucomannan-rich flour or gum derived from konjac. FAO/JECFA lists konjac flour under INS 425 and CAS 37220-17-0.

Commercial suitability depends on the exact grade, source, test method, application and destination-market rules. The current signed specification and batch COA govern a transaction.

Application screening

Common food grade Konjac Gum applications

Select permitted food applications and evaluate dosage and performance in the finished product.

Processed meat

Evaluate water binding, bite, yield and compatibility with salts and other hydrocolloids.

Dairy products

Use trials to optimize suspension, viscosity and mouthfeel.

Candy and jelly

Select viscosity and glucomannan grade for the target gel texture and process.

Puddings and desserts

Support body, water control and stable texture in compatible systems.
