Ferrous gluconate is an iron(II) gluconate salt used globally as both a nutrient supplement (iron source) and a colour retention agent, with Codex/JECFA providing internationally referenced specifications and use provisions (INS 579). In Codex GSFA, ferrous gluconate is explicitly provisioned for use in olives (including oxidized/darkened table olives) as a colour retention agent, supporting trade in processed olive products. In international merchandise trade statistics, ferrous gluconate is typically captured within HS 291816 (gluconic acid, its salts and esters), where UN Comtrade/WITS partner views show substantial cross-border flows linking exporters such as China, France, India, and the United States with import markets including India, Japan, the United States, Germany, Brazil, Mexico, and Saudi Arabia. Market dynamics are strongly shaped by regulatory compliance (food additive rules and supplement standards) and by buyer specifications around purity, oxidation state, and contaminant limits.

Specification
Major VarietiesFerrous gluconate (iron(II) di-D-gluconate) dihydrate (INS 579 / E579)
Physical Attributes- Fine yellowish-grey or pale greenish-yellow powder or granules; slight odour resembling burnt sugar (JECFA specification).
- Soluble with slight heating in water; practically insoluble in ethanol (JECFA specification).
Compositional Metrics- Assay: not less than 95% on the dried basis (JECFA specification).
- Loss on drying: not less than 6.5% and not more than 10.0% (JECFA specification).
- Iron (III): not more than 2% (JECFA specification).
- Lead: not more than 2 mg/kg (JECFA specification).
Grades- Food additive grade aligned to Codex/JECFA specifications (INS 579).
- Regulated as E579 in the EU food additive framework; national requirements and permitted uses vary by jurisdiction.
- In supplement and pharmaceutical supply chains, buyer specifications commonly reference pharmacopeial and/or JECFA-aligned quality parameters (assay, oxidation state, and contaminant limits).
ProcessingWater-soluble iron(II) gluconate salt used for blending into nutrient premixes and for technological use as a colour retention agent where permitted.
Supply Chain
Value Chain- Upstream gluconate chemistry (gluconic acid/salts) and iron(II) salt formation -> drying/milling -> quality testing against specification (identity, assay, oxidation state, contaminants) -> bulk packaging -> export/import under HS heading commonly used for gluconate salts (HS 291816) -> ingredient distributor -> finished-product manufacturing (supplement blending/tableting or food processing where permitted).
Demand Drivers- Micronutrient supplementation and iron fortification demand (nutrient supplement use recognized in international additive evaluations).
- Use as a colour retention agent in specific food applications permitted under Codex GSFA (notably olives, including oxidized/darkened table olives).
Risks
Food Safety HighSpecification non-compliance and contamination (notably heavy metals) is the most critical trade-disrupting risk for ferrous gluconate because it is used in foods and dietary supplements and is subject to strict buyer and regulator limits. JECFA specifications include defined purity and contaminant requirements (e.g., assay requirements and a lead limit), so out-of-spec material can trigger shipment rejections, recalls, or regulatory actions across multiple jurisdictions.Qualify suppliers with documented food/supplement GMP controls; require JECFA-aligned CoAs; verify assay/oxidation state and heavy metals (including lead) via accredited third-party testing; maintain lot traceability.
Regulatory Compliance MediumPermitted uses, maximum levels, and labeling requirements differ across jurisdictions (e.g., Codex provisions for INS 579, EU authorization as E579, and U.S. regulatory listings). Misalignment between intended use and local regulations can restrict market access even when the ingredient meets specification.Map intended use-cases to destination-country regulations (Codex/EU/U.S. and local rules); maintain up-to-date regulatory dossiers and product documentation for customs and food authority review.
Supply Concentration MediumFerrous gluconate is typically captured within the broader HS 291816 gluconate category in trade statistics, where UN Comtrade/WITS partner views show strong dependence of several large import markets on shipments from China for gluconate salts. Disruptions to Chinese production or logistics can therefore transmit quickly into global availability and pricing for gluconate-based ingredients.Dual-source across multiple exporting origins (e.g., China plus at least one alternative such as France/India/U.S. suppliers); carry safety stock for critical premix programs.
Chemical Stability LowOxidation of ferrous (Fe2+) to ferric (Fe3+) forms can impact conformity with oxidation-state-related specifications (JECFA includes an iron(III) limit). Handling, storage, and packaging conditions can therefore affect acceptance for sensitive applications.Use appropriate packaging and storage controls; monitor iron(III) as a release parameter for high-spec markets.
Sustainability- Industrial manufacturing footprint tied to gluconate supply chains (often glucose-derived gluconates) and associated energy/wastewater management considerations in chemical/biotech production.
FAQ
What is ferrous gluconate used for in global food and supplement markets?Internationally, ferrous gluconate is used as a nutrient supplement (an iron source) and, where permitted, as a colour retention agent. Codex GSFA provisions for INS 579 include use in olives (including oxidized/darkened table olives) as a colour retention agent.
What international identifiers are commonly used for ferrous gluconate?In Codex systems, ferrous gluconate is identified as INS 579. In the EU food additive system, it is identified as E579.
What are key quality specification parameters buyers commonly look for?JECFA specifications include identity and purity parameters such as minimum assay on a dried basis, limits on loss on drying, a maximum limit for iron(III), and a contaminant limit for lead. These types of parameters are commonly used to support compliance for food and supplement supply chains.
