Market
Calcium DL-malate (CAS 17482-42-7) is a manufactured calcium salt of malic acid that is recognized internationally as a food additive under the Codex/INS system (INS 352(ii)). It is positioned as a specification-driven ingredient used for formulation functions such as acidity regulation and flavour enhancement, with market access shaped by additive approvals and compliance expectations. Unlike seasonal agricultural commodities, supply is linked to industrial organic-acid and mineral-salt manufacturing and is traded primarily as a stable bulk powder. Trade transparency can be limited because customs reporting often aggregates it within broader organic acid derivative categories, so buyers typically manage risk through supplier qualification, COAs, and impurity controls rather than origin-season arbitrage.
Specification
Physical Attributes- Typically supplied as a white to off-white crystalline powder or granules (food/additive grade forms may vary by hydrate and particle size specification)
- Stable, non-seasonal manufactured ingredient; lot-to-lot consistency managed via specification and QC testing
Compositional Metrics- Identity and assay/purity testing aligned to applicable food-additive specifications (e.g., JECFA specifications for Calcium DL-malate)
- Elemental calcium content reporting (buyer specification parameter for nutrition applications)
- Moisture / loss on drying controls to manage caking and handling
- Impurity limits (notably heavy metals) managed against applicable specifications (e.g., JECFA metals limits)
Grades- Food additive grade (Codex/JECFA-referenced specifications)
- Food grade / nutraceutical ingredient grade (jurisdiction-dependent)
- Pharmaceutical grade (where applicable and supported by pharmacopeial specifications)
Packaging- Moisture-barrier inner liner with outer bag, carton, or fiber drum for bulk shipment
- Lot-coded packaging with Certificate of Analysis (COA) and traceability documentation for regulated markets
ProcessingParticle size distribution and bulk density can be specified to support blending and tableting workflowsHygiene and contamination control (foreign matter, metals) are critical for downstream food/supplement use
Risks
Food Safety HighAs a food additive/ingredient used in regulated supply chains, the most critical disruption risk is non-compliance due to impurities (notably heavy metals) or specification failures, which can trigger shipment rejections, recalls, or import holds. JECFA specifications explicitly address metals limits and identity/purity expectations, making analytical control central to market access.Buy to a clearly defined specification aligned to JECFA/Codex expectations; require lot-level COAs and verify with third-party testing for identity and heavy metals; qualify suppliers with robust GMP and traceability.
Regulatory Compliance MediumPermitted uses and specification references differ across jurisdictions (Codex/INS, EU E-number system, and national frameworks), and ongoing re-evaluation workstreams can change data requirements or conditions of use for malic acid and malates.Maintain a jurisdiction-by-jurisdiction regulatory dossier (identity, specs, uses/levels) and monitor re-evaluation updates; align labeling and additive identifiers to the destination market.
Quality Variability MediumPhysical property variability (hydrate form, particle size, flowability, moisture) can affect blending, tableting, and dosing uniformity in supplements and premixes, even when chemical identity is correct.Specify and test critical physical parameters (PSD, bulk density, moisture, flow) and validate performance in the target manufacturing process.
Input Cost Volatility LowPricing and availability can be influenced by upstream malic acid and calcium-source markets, energy costs, and compliance costs tied to higher testing and documentation requirements.Use multi-sourcing for qualified suppliers, lock in specifications across alternates, and establish safety stock for critical SKUs.
Sustainability- Energy and emissions footprint associated with organic-acid production and drying/milling operations
- Upstream mineral sourcing impacts where calcium inputs are derived from mined materials (e.g., limestone-based calcium sources)
Labor & Social- Occupational health and safety risks in chemical manufacturing (dust handling, process safety) requiring robust EHS management
- Worker health and safety considerations in upstream mineral extraction and processing in supply chains using mined calcium sources
FAQ
What is Calcium DL-malate used for in food applications?JECFA lists Calcium DL-malate (INS 352(ii)) as a food additive with functional classes including acidity regulator and flavour enhancer, meaning it can be used to help control pH and support flavor in formulated foods where permitted.
What do the identifiers INS 352(ii), E352, and CAS 17482-42-7 refer to?INS 352(ii) is the Codex/JECFA identifier used for Calcium DL-malate in the JECFA food additive database, and CAS 17482-42-7 is its chemical registry number. In the EU additive system, malates are grouped under E 352 (calcium malates), and EFSA lists calcium malate and calcium hydrogen malate under the E 352 family.
Is calcium malate the same as calcium citrate malate?No. PubChem lists calcium malate and calcium citrate malate as distinct substances with different compositions and identifiers, even though both are calcium-containing organic-acid salts.
