What is Konjac Gum?

Konjac Gum, derived from the traditional Asian konjac plant’s underground corm, is gaining significant attention in the global food and health industries for its exceptional functionality and health benefits. This natural dietary fiber, primarily composed of glucomannan, carries centuries of traditional use while demonstrating remarkable potential in modern food science applications.

Konjac Gum is a pure natural water-soluble dietary fiber extracted from the konjac corm. Its primary active component is glucomannan, a unique polysaccharide with exceptionally high molecular weight and water-absorption capacity. This distinctive property allows it to form high-viscosity gels in water, making it valuable across food, pharmaceutical, and industrial applications.

Production and Processing

Contemporary production methods adopt standardized, automated production lines to ensure higher purity, stable quality, and consistent batch-to-batch uniformity, meeting global industrial production requirements:
  • Advanced automated washing and impurity removal systems to reduce heavy metal and microbial residues
  • Precision controlled low-temperature drying processes to preserve glucomannan molecular integrity and activity
  • Ultra-fine precision grinding to achieve uniform particle size and excellent solubility
  • Strict quality testing at every production stage, from raw material inspection to finished product delivery
  • Dust-free, moisture-proof packaging in sterile environments to extend shelf life

Global Regulatory Compliance & Certification

As a globally circulated food additive and dietary fiber raw material, konjac gum has obtained authoritative safety certifications and unified regulatory standards in major global markets, serving as core decision-making credentials for international B2B buyers, manufacturers, and formulators.

1. U.S. FDA GRAS Status

Konjac gum (konjac glucomannan) is officially recognized as GRAS (Generally Recognized As Safe) by the U.S. Food and Drug Administration (FDA), with official GRAS notices including GRN 328 and GRN 407. It is legally approved for widespread use in food, beverages, dietary supplements, and functional food formulations in the U.S. market. It complies with FDA’s good manufacturing practice (GMP) requirements, with no usage limit restrictions for conventional food applications when used within standard formulation ratios. All qualified konjac gum suppliers must complete FDA facility registration and product safety filing to meet U.S. import and sales standards.

2. European Union Official Standard (E425)

In the European Union, konjac gum is classified as a legal food additive with the unified code E425, subdivided into two standardized categories under EU Regulation 1333/2008 and Commission Regulation (EU) 231/2012, ensuring precise industry classification:

  • E425i: Konjac Gum – Water-extracted konjac hydrocolloid, mainly used for food thickening, stabilization and gelling
  • E425ii: Konjac Glucomannan – High-purity ethanol-purified glucomannan, mainly applied in high-end supplements, functional foods and cosmetic formulas

The EU has clear usage specifications for E425: it is approved for most food categories, with only restricted use in mini jelly cups to avoid choking risks. All konjac gum entering the EU market must comply with E425 purity standards, microbial limits and heavy metal residue specifications.

3. Global Market Safety Standards & Certifications

Beyond FDA and EU regulations, konjac gum meets mainstream food safety standards worldwide, supporting global distribution and multi-scenario applications:
  • China GB Standard: Complies with GB 28308 national food additive safety standard, the core export quality standard for Chinese konjac raw materials
  • International Certification System: Qualified products support ISO22000 food safety management system, HACCP hazard control, BRC global food safety standard, HALAL and KOSHER kosher certifications, covering mainstream global trading markets
  • Other Regional Approvals: Officially approved for food and supplement use in Australia, New Zealand, Southeast Asia, and Middle Eastern markets, with unified safety recognition across global food regulatory authorities
For B2B purchasers, complete regulatory qualification documents (COA, GRAS filing certificate, E425 standard compliance report, third-party test reports) are essential to ensure customs clearance, market access and product compliance.
