ISO 34259 Multi-Residue Profiling in Frozen Foods
The ISO 34259 multi-residue profiling methodology provides a comprehensive approach to pesticide residue testing in frozen foods. This service is specifically designed for the Food & Feed Testing sector, ensuring that the residues of various pesticides are accurately and reliably identified and quantified.
Developed by experts in the field, ISO 34259 ensures high sensitivity and selectivity, allowing for precise identification of multiple residues simultaneously. This method is particularly useful in frozen foods where pesticide residues can be more challenging to detect due to their lower concentrations and potential masking effects from freezing processes.
The test involves several key steps: sample preparation, extraction, clean-up, concentration, and analysis using liquid chromatography-tandem mass spectrometry (LC-MS/MS). This approach ensures that even trace levels of pesticides can be detected with high accuracy. The multi-residue profiling aspect allows for the simultaneous testing of a broad spectrum of pesticides, which is crucial in ensuring compliance with international standards.
Compliance with ISO 34259 is essential not only for regulatory purposes but also to maintain consumer confidence and ensure product safety. This test helps manufacturers and suppliers verify that their products meet strict residue limits set by regulatory bodies like the European Union, United States, and others.
The methodology covers a wide range of pesticides including organophosphates, carbamates, pyrethroids, and other commonly used chemicals in agriculture. Each pesticide has its own set of parameters such as detection limit, quantitation limit, and matrix effect considerations which are crucial for accurate testing.
Preparation of frozen food samples prior to analysis is critical. Samples need to be thawed carefully under controlled conditions to prevent any degradation or loss of volatile components that could affect the results. Extraction methods used in ISO 34259 include QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) which ensures efficient extraction without overloading the sample matrix.
The extracted samples are then subjected to clean-up processes such as solid phase extraction (SPE) or dispersive liquid-liquid microextraction (DLLE), followed by concentration if necessary. Finally, these concentrated extracts undergo thorough analysis via LC-MS/MS which provides high-resolution spectra allowing for detailed identification and quantification of the residues present.
The results from this testing are reported in accordance with ISO 34259 guidelines providing clear information about each detected pesticide including its name, concentration level, and compliance status relative to specified limits. This comprehensive report helps stakeholders make informed decisions regarding product quality and safety.
For those involved in Quality Management, Compliance Officers, R&D Engineers, and Procurement Professionals within the food industry, this service offers invaluable insights into ensuring regulatory compliance while maintaining high standards of product integrity.
