Overview

EN 15829:2010 is a CEN (European) standard that defines a validated laboratory method for the determination of ochratoxin A in currants, raisins, sultanas, mixed dried fruit and dried figs. The procedure uses high performance liquid chromatography (HPLC) combined with immunoaffinity column (IAC) cleanup and fluorescence detection. The method was validated in an interlaboratory study on naturally contaminated and spiked samples over the range 1.1 µg/kg to 11 µg/kg (see Clause 9 and Annex B for validation data). A safety warning in the standard notes that ochratoxin A is hazardous and that appropriate health, safety and regulatory precautions are the user’s responsibility.

Key topics and technical requirements

  • Principle: Extract sample with methanol + phosphoric acid, filter, dilute with phosphate buffered saline (PBS), capture ochratoxin A on an immunoaffinity column, elute, concentrate and quantify by reverse‑phase HPLC with fluorescence detection.
  • Validated range: 1.1 µg/kg to 11 µg/kg (interlaboratory study).
  • Immunoaffinity column: IAC must contain antibodies specific for ochratoxin A with capacity ≥ 100 ng and recovery ≥ 70 % for a 5 ng spike (specified solvent matrix).
  • Sample preparation: Prepare a fruit slurry (five parts fruit : four parts water); typical analytical portion uses 45 g slurry (equivalent to 25 g dried fruit) extracted with 50 ml methanol + 5 ml phosphoric acid.
  • HPLC and detection:
    • Reverse‑phase column (e.g. C18) recommended to resolve OTA from other peaks.
    • Fluorescence detection set at 333 nm excitation / 477 nm emission (or 390 nm / 440 nm when a post‑column pH shift is used).
    • Typical injection volumes and flow rates are specified to ensure reproducible quantification.
  • Reagents and consumables: PBS, acetonitrile, methanol, toluene, injection/mobile phase recipes, and certified ochratoxin A standards are required. EN ISO 3696:1995 (water quality) is normative.

Applications and users

  • Who uses it: Food testing laboratories, public health and regulatory authorities, quality control teams in dried fruit processing and trading companies, import/export inspection labs, and research groups studying mycotoxin contamination.
  • Practical purposes:
    • Routine monitoring of ochratoxin A in dried fruit to support food safety compliance.
    • Verification of supplier batches and import controls.
    • Data generation for exposure/risk assessment and product recalls.
    • Method transfer and accreditation (laboratories seeking ISO/IEC 17025 evidence).

Related standards and references

  • Normative reference: EN ISO 3696:1995 (water for analytical laboratory use).
  • Validation details: see Clause 9 and Annex B of EN 15829:2010.
  • Safety and toxicology references: International Agency for Research on Cancer (IARC) classification noted in the standard.

This standard is essential for reliable, reproducible HPLC‑based ochratoxin A analysis in dried fruit matrices and supports consistent regulatory testing across CEN member states.

Specification and test methods (ISO 3696:1987) 3 Principle A test portion is extracted with a mixture of methanol and phosphoric acid. The extract is filtered, diluted with phosphate buffered saline, and applied to an immunoaffinity column containing antibodies specific for ochratoxin A. The ochratoxin A is isolated, purified and concentrated on the column then released with elution solvent. Ochratoxin A is quantified by reverse-phase high performance liquid chromatography (HPLC) with fluorescence detection. 4 Reagents 4.1 General Use only reagents of recognized analytical grade and water complying with grade 1 of EN ISO 3696:1995, unless otherwise specified. Solvents shall be of quality for HPLC analysis. Commercially available solutions with equivalent properties to those listed may be used.

Ochratoxin A is a potent nephrotoxin with immunotoxic, teratogenic and potential genotoxic properties. The International Agency for Research on Cancer (IARC) has classified ochratoxin A as a possible human carcinogen (group 2B). Protective clothing, gloves and safety glasses should be worn at all times, and all standard and sample preparation stages should be carried out in a fume cupboard. Dissolve 1 mg of the ochratoxin A or the contents of 1 ampoule (if ochratoxin A has been obtained as a film) in solvent mixture (4.20) to give a solution containing approximately 20 µg/ml to 30 µg/ml of ochratoxin A. To determine the exact concentration, record the absorption curve between a wavelength of 300 nm and 370 nm in a 1 cm quartz cell with solvent mixture (4.20) as reference using the spectrometer (5.12). Identify the wavelength for maximum absorption. Calculate the mass concentration of ochratoxin A, ota, in micrograms per millilitre using Equation (1):
bMA×××=ερ100maxota (1) where Amax is the absorption determined at the maximum of the absorption curve (here: at 333 nm); M is the molar mass, in grams per mole, of ochratoxin A (M = 403,8 g/mol); 0 is the molar absorption coefficient, in square metres per mole, of ochratoxin A in the solvent mixture (4.20) (here: 544 m2/mol, see [2]); b
is the optical path length, in centimetres, of the quartz cell.

Confirm the concentration of the solution if it is older than six months. 4.25 Ochratoxin A spiking solution Transfer an aliquot of the stock solution (4.24) containing 12,5 µg of ochratoxin A to a 5 ml volumetric flask. Evaporate to dryness under nitrogen at no more than 50 °C. Redissolve immediately in methanol (4.16) and make up to volume. This solution contains 2,5 µg/ml ochratoxin A.
