Описание (английский):

ISO 17372:2007 is applicable to the analysis of zearalenone in animal feed and feed ingredients, including barley, corn, oats, rye, wheat, soybean meal, canola (rapeseed) meal, corn gluten, dried distillers' grains, lentils, and sugar beet pulp. The limit of quantification is 0,05 mg/kg (50 µg/kg). A lower limit of quantification may be achievable subject to appropriate validation being conducted by the user laboratory.

Overview

ISO 17372:2008 specifies a validated laboratory method for the determination of zearalenone in animal feeding stuffs using immunoaffinity column (IAC) chromatography followed by high performance liquid chromatography (HPLC) with fluorescence detection. The standard applies to a wide range of feed matrices (barley, corn, oats, rye, wheat, soybean and canola meals, corn gluten, dried distillers’ grains, lentils, sugar beet pulp, etc.) and defines a practical limit of quantification (LOQ) of 0.05 mg/kg (50 µg/kg); lower LOQs are possible with appropriate in‑house validation.

Key topics and technical requirements

Scope and matrices: Designed for common feed ingredients and complete animal feeding stuffs.

Sample preparation: Grinding to ≤1 mm (recommendation for finer particle size where practical) and representative sampling per ISO 6498 guidance.

Extraction: Organic extraction using acetonitrile‑based solvent (extraction solvent φ(CH3CN)=90 %) with salt (NaCl) followed by filtration.

IAC cleanup: Purification on zearalenone‑specific immunoaffinity columns to concentrate and remove interferences; instructions for handling pigmented or problematic matrices (use of methanol washes, filter/frit arrangements).

HPLC analysis: Reverse‑phase HPLC with fluorescence detection (excitation wavelengths including 236 nm and 274 nm, emission at ~418–440 nm). Mobile phase and standard preparation procedures are specified to generate calibration curves.

Quality control: Use of spiked control samples (e.g., 0.10 mg/kg) with recommended recovery ≥85 % and preparation of stock and working standards; evaporative concentration of IAC eluates to improve sensitivity.

Confirmation options: Wavelength ratioing, normal‑phase HPLC, or diode‑array detection for suspect positives.

Documentation: Calculation of results, precision statements, and test reporting requirements are included.

Applications and practical value

Routine mycotoxin monitoring in feed manufacturing, grain handling, and feed ingredient supply chains.

Regulatory compliance testing and surveillance by laboratories supporting veterinary public health and animal nutrition.

Quality control in feed mills and grain testing laboratories to protect animal health and prevent carry‑over of mycotoxins into animal products.

Research and method validation efforts aiming to push LOQ lower with additional laboratory validation.
