Longchangs indkøbsside for Ammoniumalginat CAS 9005-34-9. Send the destination market, intended food category or industrial function, target viscosity and complete method, required purity/microbiological limits, quantity, packaging and documents to request a current supplier specification, applicable lot COA, SDS status, sample availability, MOQ, current availability, quotation validity and confirmed lead time. No historical webpage value is a current specification or supply commitment.
Public identity fields
| Produktets navn | Ammonium Alginate; ammonium salt of alginic acid |
|---|---|
| CAS-registreringsnummer | 9005-34-9 |
| JECFA / Codex-identifikator | INS 403 |
| EU-identifikationsnummer | E403 |
| Udtryk for polymergentagelser | (C6H11NEJ6)n |
| Sammenhængen med molekylvægten | Variable polymer; JECFA reports 10,000–600,000 as a typical macromolecular range |
| Public functional-use terms | Stabilisator, fortykningsmiddel, geleringsmiddel og emulgator i JECFA-monografien |
Den FAO/JECFA-monografi, FAO record og EU-forordning nr. 231/2012 support these public fields. They do not establish the current Longchang specification, viscosity grade, lot result, food-grade status, certification, stock or application suitability.
Identity correction
The previous product page displayed C13H16N3NaO4S and molecular weight 333.33861. Those fields do not describe the official ammonium-alginate identity and are removed. Ammonium alginate is a variable-chain polymer, so qualification uses the repeat expression, identity tests, defined viscosity method and current controlled documents rather than a single small-molecule value.

Public food-additive references are not a lot specification
| Reference | Public context | Qualification boundary |
|---|---|---|
| 21 CFR 184.1133 | U.S. identity, food categories, maximum use levels and functions | Verify the current text, category, as-served calculation and complete formulation requirements |
| JECFA INS 403 monograph | Identity, functional uses and public specification tests | Confirm that the current supplier specification and lot COA use the required methods and bases |
| EU-forordning nr. 231/2012 | Identitets- og renhedskriterier for E403 | Confirm current consolidated criteria, methods and lot results |
| EU-forordning nr. 1333/2008 | EU authorization framework and Union-list context | Confirm exact food category, use conditions, labelling and destination requirements |
| EFSA’s udtalelse om E400–E404 | Exposure assessment for reported food-additive uses and documented limitations | Not a blanket product, formulation, consumer-group or market approval |
Historical source fields requiring reconfirmation
The earlier product page displayed the following values without a visible controlled specification number, complete methods, lot, effective date or approval status. They are historical RFQ context only—not current specifications, lot results or supply commitments.
| Source field | Historical display | Issue | Current RFQ requirement |
|---|---|---|---|
| Udseende | Mælkehvid til lysegul | No controlled wording, observation method or approval version | Current appearance criterion and method |
| Viscosity, 1% | 500–1000 mPa·s at 20°C | Instrument, spindle, speed, water, hydration and basis were not stated | Complete viscosity method and acceptance range |
| Fugt | ≤15.0% | Method and dry/anhydrous basis were not shown | Current limit, method and calculation basis |
| pH, 1% solution | 5.0–8.0 | Water, temperature, preparation and method were not shown | Current pH method and acceptance range |
| Partikelstørrelse | 40–60 mesh | Sieve standard and distribution criterion were not shown | Current sieve method and required distribution |
| Lead / arsenic | Rows labelled mg/kg but values displayed as ≤5% and ≤3% | Units and percentages conflict and cannot be treated as limits | Correct analyte limits, units, methods and applicable lot results |
| Tungmetaller | ≤20 mg/kg | No analyte definition or method | Element-specific limits, methods and reporting thresholds |
| Emballage | 25 kg/tromle | No current packaging configuration or availability evidence | Current net weight, liner/container, pallet and destination options |
Application and safety boundary
JECFA functional-use terms and market regulations can guide qualification, but they do not prove performance in a buyer’s formulation. Viscosity and gel behavior depend on grade, concentration, hydration, pH, ions, temperature, shear and matrix. Food, pharmaceutical, nutraceutical, encapsulation, dental, industrial or other contexts require separate product, process, quality and regulatory evidence.
JECFA and EFSA assessment language has a defined scope and is not consumer advice. This webpage is not a food-safety plan, legal determination, SDS or handling guide. Use current supplier documents with the buyer’s intended use, formulation, destination rules, quality system and risk assessment.
