Direct product answer
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
These are formulation areas, not universal approvals. Confirm legal use, dosage and technical performance for the finished product.
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.

Specification and identity note: The supplied sheet writes C6H10O5 as a molecular formula. Konjac gum is a variable high-molecular-weight glucomannan polymer, so procurement should be based on glucomannan content, viscosity, particle size and the signed grade specification rather than a single small-molecule formula.
