Overview
ISO 18419:2026 - Oilseeds - Application of near infrared spectrometry provides a standardized procedure for predicting key constituents and analytes in oilseeds and oilseed meals using near infrared spectroscopy (NIRS). Developed by the International Organization for Standardization (ISO), this standard offers a robust methodological framework for determining parameters such as moisture, fat, protein, and minor components like total glucosinolates. The spectrometric measurements are carried out in the near infrared spectral range, generally 780 nm to 2,500 nm, ensuring consistency and reliability in oilseed quality analysis across the supply chain.
Key Topics
- Near Infrared Spectroscopy (NIRS):
- Analytical technique for rapid, non-destructive assessment of oilseed composition.
- Utilizes reflection, transmittance, or transflectance methods in the near-infrared region.
- Prediction Models:
- Creation and validation of calibration models correlating NIR spectra with reference data.
- Use of multivariate prediction techniques (chemometrics) like principal component regression, partial least squares regression, and multiple linear regression.
- Quantitative Analysis:
- Prediction and measurement of oilseed constituents, including moisture, fat, protein, and glucosinolates.
- Provides standardized units and reference methods to ensure result alignment.
- Quality Assurance:
- Validation procedures, cross-validation, control of outliers, and use of independent sample sets to establish accuracy and robustness.
- Instrument standardization and routine performance checks.
- Statistical Evaluation:
- Guidance on key statistics-bias, root mean square error of prediction, coefficient of determination (R²), and ratio of performance to deviation (RPD).
Applications
ISO 18419:2026 is highly relevant to a variety of stakeholders within the oilseed sector, including:
- Oilseed Processors and Crushers:
- Implement NIRS for real-time quality monitoring of raw seeds and processed meals, ensuring compliance with product specifications.
- Food and Feed Manufacturers:
- Use fast, standardized analysis to optimize manufacturing processes and validate nutritional content.
- Quality Control Laboratories:
- Adopt a harmonized procedure for routine compositional analysis, improving reliability and traceability.
- Agricultural Producers and Traders:
- Employ NIRS for grading, contract settlement, and rapid screening before storage or shipment.
- Research and Development:
- Leverage statistical and chemometric tools established by ISO 18419:2026 for developing new prediction models tailored to specific oilseed varieties or minor constituents.
