Frequently Asked Questions

konjac.bio is an independent information and B2B sourcing reference focused on konjac, glucomannan, shirataki noodles, and wholesale konjac products. The site is designed for buyers, importers, distributors, product developers, and technical teams that need clear ingredient information before contacting suppliers. konjac.bio is not owned by a retail noodle brand and does not operate as a consumer marketplace.

No. konjac.bio does not sell retail packs, single bags, consumer bundles, or supermarket products. The site provides educational information and supports B2B sourcing conversations when a company has a wholesale requirement. If you are looking for one pack of noodles or a retail supplement, use a local retailer, grocery platform, or supplement seller rather than the konjac.bio contact form.

No. konjac.bio is information-only for consumers and B2B-oriented for sourcing. We do not process retail checkout, ship single consumer orders, or recommend specific retail brands. Consumer readers can use the site to understand konjac, glucomannan, and shirataki formats, but purchase decisions should be made through retailers that display ingredients, serving size, allergen statements, and country-specific labeling.

konjac.bio can help route wholesale conversations from sample-stage projects to pallet, distributor, and container-level programs. Final MOQ is set by the supplier and depends on product type, grade, packaging, production schedule, certification, and shipping market. A dry glucomannan powder MOQ can differ from a wet shirataki noodle MOQ because shelf life, packaging, and freight requirements are different.

Buyers can ask about konjac flour, konjac gum, purified glucomannan powder, premixes, shirataki noodles, rice-style konjac formats, jelly ingredients, and finished goods for wholesale programs. The best inquiry names the exact application, such as noodle manufacturing, beverage texture, bakery fiber, capsule filling, or ready-to-sell pouch products. Clear use cases help match viscosity, particle size, purity, and packaging.

Certification options vary by supplier and facility. Common requests include ISO 22000, HACCP-based controls, Kosher, Halal, non-GMO statements, allergen statements, and vegan suitability documents. ISO 22000 is an international food safety management standard described by [ISO 22000](https://www.iso.org/standard/65464.html), while HACCP principles are maintained through [Codex HACCP](https://www.fao.org/fao-who-codexalimentarius/thematic-areas/food-hygiene/en/). Buyers should verify certificate scope, expiry date, and product coverage.

Yes, a COA is commonly available for wholesale konjac ingredients and finished product lots, but the exact test panel depends on the supplier and specification. A typical COA may include appearance, moisture, viscosity, particle size, ash, sulfur dioxide, pH, microbial limits, and heavy metals where relevant. Buyers should request a sample COA early, then confirm final COA requirements before production.

Third-party lab testing may be available by agreement for wholesale lots, especially for large programs, regulated channels, or buyer-specific specifications. Common test categories include microbiology, heavy metals, sulfur dioxide, gluten status, pesticide screens, and identity checks. The buyer should define the lab, method, acceptance limits, sample handling process, and who receives the final report before the order is placed.

Sample availability depends on product format, stock status, export route, and supplier approval. Buyers should provide company name, email domain, destination country, product type, intended application, annual volume estimate, and required certifications. Some samples are standard retained stock, while others require small-batch preparation. Freight method, customs paperwork, and import rules can affect whether a sample can be shipped.

A complete B2B inquiry usually receives a first response within 1 to 2 business days. Complex projects can take 3 to 5 business days when they involve several product formats, certification checks, private-label packaging, or multiple destination markets. Inquiries with missing product type, volume, destination, or company details may take longer because the sourcing requirement is not yet clear.

konjac.bio can support discussions for North America, Europe, and APAC, subject to supplier capability and local import requirements. Dry ingredients are usually easier to route than wet, refrigerated, or short-shelf-life finished products. Buyers should define the destination country, delivery terms, warehouse address or port, document needs, and whether the shipment is for foodservice, manufacturing, distribution, or retail channels.

White-label usually means an existing konjac product or formula is adapted with the buyer’s branding, label artwork, and packaging language. Private-label usually involves a buyer-specific formula, specification, package size, compliance route, or exclusive commercial setup. White-label can be faster when stock formats already exist. Private-label can offer more control, but it often requires larger volume commitments and longer setup time.

Konjac is widely used as a food ingredient, but safety depends on format, serving size, hydration, and intended consumer group. Glucomannan powder absorbs water quickly, so directions should be followed carefully. FDA has flagged certain konjac mini-cup jelly candies because of choking concerns in that format, shown in the [FDA alert](https://www.accessdata.fda.gov/cms_ia/importalert_110.html). For a fuller overview, see konjac safety.

FDA does not approve dietary supplements for effectiveness before sale. In the United States, glucomannan supplement products are generally handled within the dietary supplement framework described by [FDA supplements](https://www.fda.gov/food/dietary-supplements) and [FDA Q&A](https://www.fda.gov/food/information-consumers-using-dietary-supplements/questions-and-answers-dietary-supplements). This is different from saying a specific product is FDA-approved. Buyers should verify ingredient status, labeling, claims, and import compliance for their own market.

In the European Union, EFSA evaluated glucomannan claims under specified conditions. Approved wording includes: "Glucomannan in the context of an energy restricted diet contributes to weight loss," as covered in the [EFSA opinion](https://www.efsa.europa.eu/en/efsajournal/pub/1798) and searchable in the [EU register](https://ec.europa.eu/food/food-feed-portal/screen/health-claims/eu-register). Any commercial label should follow exact wording, required intake levels, and market rules.

No. konjac.bio does not publish prices on the FAQ page because wholesale pricing depends on product type, grade, packaging, volume, certification, origin, freight route, and contract terms. A meaningful quotation requires a defined specification and destination. Buyers should use the contact form for sourcing requests, but should not expect consumer pricing, retail coupons, or public price lists.

Send a clear sourcing request with product type, target grade, application, estimated annual volume, destination country, packaging format, certification needs, sample request, and required documents. If the project is private-label or white-label, include target pack size, language markets, shelf-life expectations, and launch timing. Complete information reduces back-and-forth and helps route the inquiry to a suitable supplier conversation.
