| 1 | Correct E423 Identity | E423 is the European food-additive designation for octenyl succinic acid modified gum arabic. Its international numbering reference is INS 423. | Product specification, ingredient declaration, manufacturing description, current regulatory statement, and confirmation that the material is not ordinary unmodified gum arabic. | Buying a different gum or starch-based emulsifier under an incorrect E-number. | Mandatory |
| 2 | Destination-Market Approval | Food-additive authorization is jurisdiction-specific. E423 approval, permitted food categories, maximum use levels, and labeling rules must be checked separately for each target market. | Country-specific compliance statement, legal references, permitted-food-category assessment, and written confirmation of intended use. | Shipment rejection, relabeling, recall, or inability to legally sell the finished food. | Mandatory |
| 3 | EU Purity-Requirements Alignment | For products placed on the EU market, food additives must meet the applicable specifications established under Commission Regulation (EU) No 231/2012, as amended. | A specification cross-reference showing conformity with the current EU purity criteria and the supplier’s latest certificate of analysis. | A product may be technically functional but fail a statutory purity or identity requirement. | Mandatory for EU |
| 4 | Certificate of Analysis Quality | A lot-specific COA should identify the batch, production date, test date, analytical method, result, unit, specification limit, and authorized approval. | Recent COAs from multiple production lots covering identity, appearance, moisture, ash or inorganic residue where applicable, pH or dispersibility where specified, and microbiology. | Inconsistent lots, unverifiable results, or difficulty proving compliance during an audit. | Mandatory |
| 5 | Microbiological Control | Microbiological limits are application- and market-dependent. Controls commonly include total aerobic count, yeast and mold, coliforms or Enterobacteriaceae, and absence or limits for specified pathogens. | Microbiological specification, test methods, laboratory accreditation information, environmental-monitoring summary, and pathogen-control statement. | Food-safety nonconformity, shortened shelf life, or contamination of the finished product. | Mandatory |
| 6 | Contaminant and Residue Controls | Contaminant requirements can include heavy metals, pesticide residues, residual processing chemicals, mycotoxins where relevant, and other substances controlled by the importing market. | Recent contaminant test reports, risk-based monitoring plan, pesticide declaration, heavy-metal results, and compliance with applicable maximum levels. | Border detention, failed customer audits, or non-compliance with finished-food legislation. | Mandatory |
| 7 | Functional Performance | E423 is selected for functions such as emulsification and stabilization. Performance depends on concentration, processing conditions, oil phase, pH, temperature, and the food matrix. | Technical data sheet, recommended use range, application trials, dispersion procedure, emulsion-stability results, and sample-to-commercial-lot comparison. | Poor emulsion stability, sedimentation, processing problems, or failure to reproduce laboratory results. | Mandatory |
| 8 | Food-Safety Management System | A credible food-ingredient supplier should operate a documented HACCP-based system. Certifications such as FSSC 22000, BRCGS, or IFS can provide additional audit evidence but do not replace legal compliance. | Valid certificate, certification scope, issuing-body details, latest audit status, HACCP summary, allergen program, and change-control procedure. | Weak preventive controls, unmanaged process changes, or inadequate corrective actions. | Strongly recommended |
| 9 | Traceability and Supply Continuity | Food-ingredient traceability should connect raw-material lots, processing records, finished-product batches, packaging, shipment documents, and customer delivery records. | Mock recall results, lot-number structure, origin statement, approved raw-material sources, production capacity, lead time, safety-stock policy, and business-continuity plan. | Slow recall response, undocumented origin, production interruption, or unstable delivery schedules. | Mandatory |
| 10 | Packaging, Storage, and Commercial Terms | Packaging must protect the powder or granulated ingredient from moisture and contamination. Storage conditions, shelf life, minimum order quantity, Incoterms, and documentation requirements should be agreed before purchase. | Packaging specification, net-weight tolerance, storage instructions, shelf-life statement, pallet configuration, SDS where applicable, MOQ, Incoterm, payment terms, and retention-sample policy. | Caking, moisture uptake, damaged cargo, unexpected landed cost, or unusable remaining shelf life. | Mandatory |
