ISO 28961 Herbicide Residue Testing in Rice-Based Products
The demand for safe and sustainable food products has never been higher, especially as global populations continue to grow. Ensuring that rice-based products are free from harmful herbicides is critical not only for consumer safety but also for maintaining the integrity of agricultural practices.
ISO 28961 establishes a harmonized method for determining pesticide residues in rice and rice-based products, including those intended for direct human consumption. This standard provides a robust framework that ensures consistent and reliable results across different laboratories. Compliance with this ISO standard is essential for food manufacturers, suppliers, and regulatory bodies to ensure the safety of their products.
Our laboratory employs advanced analytical techniques such as Liquid Chromatography-Mass Spectrometry (LC-MS/MS) to perform herbicide residue testing in rice-based products. This method allows us to detect even trace levels of pesticides, ensuring that our results are accurate and reliable. The standard specifies a series of steps for sample preparation, extraction, purification, and final analysis.
The process begins with the collection of representative samples from various batches or lots of rice-based products. These samples must be stored under controlled conditions to prevent degradation of pesticides. Once collected, the samples are prepared according to ISO 28961 guidelines, which involve thorough grinding followed by extraction using solvents like acetonitrile.
Following extraction, the sample is purified through a series of filtration steps and centrifugation to remove impurities. The final step involves diluting the extract before injection into an LC-MS/MS instrument for analysis. This method ensures that only the target herbicide residues are detected, minimizing interference from other components in the sample.
The results obtained from the LC-MS/MS system are then compared against established reference values provided by ISO 28961. These reference values define the maximum residue limits (MRLs) for various herbicides according to their toxicity and usage patterns. MRLs vary based on the specific pesticide, its intended use, and the part of the product being analyzed.
Our laboratory ensures that all tests are conducted in accordance with ISO 28961 requirements. This includes maintaining traceability of standards, using certified reference materials (CRMs), and adhering to Good Laboratory Practices (GLPs). By doing so, we guarantee accurate and reliable results every time.
In summary, implementing ISO 28961 for herbicide residue testing in rice-based products is crucial for maintaining food safety standards. Our laboratory uses cutting-edge technology combined with strict adherence to international standards to provide trustworthy test results that meet regulatory requirements.
