Food-grade thickener sourcing with an IDDSI-aligned verification workflow
This page explains how Asaptic sources food-grade, cold-water-soluble thickening powders for food ingredient / food additive applications. It describes our R&D gate workflow, IDDSI Flow Test alignment for texture verification, and the supplier documents we request before any volume commitment.
Not medical advice. Asaptic is a B2B sourcing platform — not a clinician, dietitian, or regulatory authority. Nothing on this page is dysphagia care guidance, a patient recommendation, or an IDDSI compliance certification. Final texture classification for clinical use must be confirmed by qualified professionals using the official IDDSI Flow Test (and Fork Drip / Spoon Tilt tests for Level 4) per IDDSI Testing Methods v2.0.
IDDSI-aligned sourcing workflow
IDDSI normatively classifies drink thickness using the 10 mL syringe Flow Test (gravity, 10 seconds) — not viscometry alone. Our sourcing workflow treats viscosity bands and cold-dispersion checks as R&D screening proxies that must be confirmed by a physical Flow Test before any product is represented as meeting a specific IDDSI level.
- Define food-grade specs. Pre-gelatinized starch base (e.g. E1442), cold-water solubility, mesh band, moisture ceiling, and target viscosity tiers at declared dose (g per 200 mL).
- Track-A starch gate. Incoming starch must disperse in cold water without fish-eyes or a needs-cooking failure — wrong starch track is re-sourced, not blended around.
- R&D lab gates. Cold dispersion, viscosity at declared shear/temperature, 15-minute stability drift, and alpha-amylase challenge (viscosity loss ceiling) — each recorded as structured measurements, not pass/fail guesses when docs are missing.
- IDDSI Flow Test confirmation. For any level claim, run the official 10 mL syringe Flow Test at the target dose. Viscosity bands (e.g. 150–300 mPa·s proxy for Level 2) are screening aids only until the Flow Test result is on file.

licences, COAs, or type-inspection reports receive a
needs_documentsverdict — never a fabricated pass.
R&D viscosity tiers (screening proxies)
These tiers mirror our internal R&D preset bands. They are not substitutes for the IDDSI Flow Test.
Level 2 proxy — Mildly Thick
7.6 g / 200 mL · screening band 150–300 mPa·s (3# rotor, 10 rpm, 20 °C). Confirm with Flow Test: 4–8 mL remaining.
Level 3 proxy — Liquidised Thick
11.4 g / 200 mL · screening band 600–1,200 mPa·s. Confirm with Flow Test: 8–10 mL remaining.
Level 4 proxy — Extremely Thick
13.3 g / 200 mL · screening band ≥1,800 mPa·s. Confirm with Fork Drip and Spoon Tilt tests — Level 4 does not flow through the syringe test.
Supplier document requirements
Before any volume order, each supplier must provide sample material plus the documents below.
Missing items surface as needs_documents — buyers can request uploads; Asaptic does not invent compliance data.
| Document | Why we request it |
|---|---|
| Business licence (营业执照) | Verifies the legal entity supplying the ingredient. |
| Food production licence SC (食品生产许可证) | Photo showing licence number and validity for food-manufacturing scope. |
| Type-inspection report (型式检验报告) | Independent product-type testing report, in date for the SKU family. |
| Certificate of Analysis (COA) | Batch-level test results for the specific sample supplied. |
| Food-grade declaration | Written confirmation the material is sold as a food ingredient / additive. |
| Sample (0.5–1 kg) + spec sheet | Enables Track-A starch gate and R&D measurements before bulk commitment. |
| Optional: BRC / FSSC 22000 / Halal / Kosher | Captured when on file; absence does not auto-fail if core food licences and COA are present. |
