What is the standard HPLC assay method used for Aronia anthocyanin quantification in supplement-grade extracts?

The standard method is reversed-phase HPLC with UV-Vis detection (typically 520 nm), quantifying the four dominant Aronia anthocyanins — cyanidin-3-galactoside, cyanidin-3-arabinoside, cyanidin-3-xyloside, and cyanidin-3-glucoside — expressed as total anthocyanins in mg/g or % using cyanidin-3-glucoside as the reference standard. The COA supplied by TANDOR for each batch states the specific HPLC method used and the instrument calibration standard, allowing your QC team to cross-validate against in-house methods.

Does Aronia have any authorised EFSA health claims that can be used on EU supplement labels?

No. As of the current EU Register under Regulation (EC) No 1924/2006, no health claim has been authorised for Aronia melanocarpa by EFSA. General antioxidant claims for polyphenol-rich botanical extracts remain on the on-hold list. Supplement brands must rely on non-claim positioning, nutrition panel data, or pursue a substantiated Article 13.5 proprietary claim. We recommend consulting the official EU Register of nutrition and health claims before finalising label copy.

What particle size specification should I request for Aronia extract destined for hard capsule filling?

For standard capsule filling equipment, specify D90 ≤ 250 µm and confirm bulk density (g/mL) and tapped density in the TDS to calculate accurate fill weights. Spray-dried Aronia extracts typically have a D50 in the 50–150 µm range, but this varies by processor and carrier system (maltodextrin vs. acacia gum). TANDOR requests particle size distribution data by laser diffraction (per ISO 13320) from suppliers as part of the standard qualification file.

What is the minimum order quantity for EU-Organic certified Aronia extract, and how is the organic chain of custody documented?

Minimum order quantities for standardised Aronia extract typically start at 25 kg for qualification batches, with production volumes supplied in 25 kg net drums. EU-Organic chain of custody is documented via the operator's organic certificate (issued under Regulation (EU) 2018/848 by an accredited control body) and a transaction certificate for each shipment, both verifiable through the TRACES NT platform. TANDOR provides both documents as part of the standard delivery documentation package.

What Supplement Formulators Need to Know About Aronia

Aronia melanocarpa (black chokeberry) is one of the most anthocyanin-dense botanical raw materials commercially available in Europe. For nutraceutical and supplement manufacturers, the critical purchasing decision is not simply "Aronia extract" — it is specifying the correct standardisation level, assay method, physical form, and certification stack before issuing a purchase order.

Forms & Specifications That Matter for This Application

Standardised Dry Extract (the primary form for capsule/tablet manufacturing)

The most widely specified form in supplement formulation is a spray-dried or freeze-dried extract standardised to total anthocyanins and/or total polyphenols, with values expressed as cyanidin-3-glucoside equivalents (C3G eq.) or as gallic acid equivalents (GAE), depending on the target claim.

Typical specification parameters requested by supplement brands:

Anthocyanin content: commonly specified in the range of 1–25% total anthocyanins (HPLC), with mid-range 10–15% extracts the most requested for standard-dose capsule formats
Total polyphenols: often co-reported as ORAC or Folin-Ciocalteu (expressed as GAE per gram), though Folin-Ciocalteu is a colorimetric method and HPLC is the preferred assay for regulatory-grade COAs
Assay method: HPLC (High-Performance Liquid Chromatography) is the industry-accepted standard for quantifying individual anthocyanins — specifically cyanidin-3-galactoside, cyanidin-3-arabinoside, cyanidin-3-xyloside, and cyanidin-3-glucoside — and should be explicitly stated on the COA
Carrier/excipient: maltodextrin (most common), acacia gum, or rice bran extract — relevant for allergen declarations and label claims
Loss on drying (LOD): typically ≤5% for spray-dried powder
Heavy metals: compliant with limits under Regulation (EC) No 1881/2006 and amendments
Microbiology: Total Plate Count, Yeast & Mould, absence of Salmonella spp. and E. coli per Ph. Eur. microbiological criteria for herbal preparations

Whole-Berry Powder (for high-dose or clean-label formats)

Freeze-dried or spray-dried whole-berry powder retains the full phytochemical profile without concentration. It is preferred in high-dose softgels, functional food formats, and clean-label SKUs where "whole fruit" positioning is commercially important. Total anthocyanin content in whole-berry powder is inherently lower (typically 1–3% as-is) and is crop- and harvest-dependent, making batch-specific COA review essential.

Particle Size Considerations for Capsule Manufacturing

For direct capsule filling, particle size distribution directly affects flow rate, fill weight consistency, and capsule machine performance:

D90 ≤ 250 µm is a common specification for standard capsule filling lines
D50 typically in the 50–150 µm range for spray-dried extracts
Particle size is reported by laser diffraction (e.g. per ISO 13320) and should be included in the technical data sheet (TDS)
Bulk density and tapped density values (relevant for capsule fill weight calculations) should be confirmed pre-order

EU-Organic Certification & Regulatory Positioning

EU-Organic status under Regulation (EU) 2018/848 is increasingly a hard requirement — not a preference — for premium supplement brands selling into the EU, UK, and export markets. TANDOR supplies Aronia raw materials with valid EU-Organic certification, issued by an accredited control body, and the certificate is verifiable per the TRACES NT system.

Additional certifications relevant to this buyer segment:

ISO 22000 / FSSC 22000 food safety management at processing level
Halal and Kosher certification available for selected origins and processors
GMP-compliant processing (relevant where the extract is intended for use in a licensed supplement manufacturing facility)
Allergen and GMO declaration — Aronia is not a listed allergen under Regulation (EU) No 1169/2011, and non-GMO status is declarable for EU-origin material

EFSA Health Claim Status

As of current EFSA registers, no Article 13.1 or Article 14 health claim has been authorised for Aronia melanocarpa under Regulation (EC) No 1924/2006. Supplement brands must therefore position Aronia within general botanical or nutritional frameworks, or pursue substantiation under Article 13.5 if a proprietary claim is intended. Claims relating to "polyphenols" or "antioxidants" for berries remain on the on-hold list pending further EFSA evaluation — formulators should review the current EU Register of authorised claims before finalising label copy.

Origin, MOQ & Supply Realities

Aronia melanocarpa is cultivated commercially across Poland, Romania, Ukraine, and the Baltic states, with Poland and Romania representing the largest EU-certified production volumes. Each origin carries different crop calendar timing, extraction infrastructure, and certification depth.

MOQ and supply structure:

Standardised extracts: typical minimum order quantities begin at 25 kg for initial qualification batches, scaling to full-drum (typically 25 kg net) or pallet quantities for production runs
Whole-berry powder: MOQs typically start at 50–100 kg depending on processor
Crop seasonality: main harvest July–September; extract availability is year-round from stored inventory, but crop-year lot traceability should be confirmed on the COA
