Konjac Gum Glucomannan Powder Food Grade CAS 37220-17-0

Food-grade konjac gum / glucomannan powder candidate for overseas buyers seeking plant-based thickener, stabilizer, or gelling ingredient. Key checks should focus on CAS 37220-17-0, food-grade status, glucomannan content, viscosity method, mesh size, heavy metals, SO2, microbiology, packing format, and export document readiness. This listing is not a xanthan gum match and should be treated as an alternative hydrocolloid only after formulation and regulatory review.

Applications and sourcing options

Check whether this product fits the buyer's actual application.

Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.

Use context

Common applications

  • Thickener or stabilizer in jelly, jam, beverages, seasoning powders, soup powders, and cold drink applications subject to local approval
  • Binder or texture modifier in noodles, rice noodles, meat products, bakery products, and related food formulations subject to formulation testing
  • Gelling ingredient in confectionery or jelly-type food products where konjac gum is permitted
  • Alternative hydrocolloid evaluation where xanthan gum was searched but a different texture or gelling profile may be acceptable
How we compare

Sourcing options

  • Food-grade konjac gum, 80% min glucomannan, 120–200 mesh, 25 kg bags
  • Higher-viscosity or lower-viscosity konjac gum grades subject to supplier confirmation
  • Small-pack samples or pilot quantities for formulation validation
  • Bulk export shipment by sea for commercial orders
  • Air shipment for urgent samples or limited quantities, subject to document and transport classification review
  • Consider separate RFQ for xanthan gum if the buyer specifically requires xanthan gum rather than konjac gum
Human review

Compliance notes

  • Verify CAS 37220-17-0 and product identity as konjac gum / konjac glucomannan rather than xanthan gum
  • Request recent COA matching the offered batch, including viscosity test method, glucomannan assay, mesh size, SO2, heavy metals, and microbiology
  • Request specification sheet, SDS, allergen statement, non-GMO statement if required, halal/kosher certificates if relevant, and food additive declaration for the destination market
  • Source page references BRC and ISO certification; buyers should request current certificates and scope pages before approval
  • For Indonesia supply, confirm BPOM-related documentation needs, halal requirements where applicable, import HS code, and permitted food additive use with local counsel or importer
  • Konjac gum may have destination-specific food additive limits, labeling requirements, and naming rules; supplier statements should be verified against buyer market requirements
  • No dangerous goods classification is indicated from the listing, but buyers should request SDS and transport classification confirmation before booking air or sea freight
  • Export documents to request: commercial invoice, packing list, COA, SDS, certificate of origin, health/sanitary certificate if applicable, and phytosanitary or food safety documents if required by importer
