ISO 46222 Residue Analysis in Frozen Vegetables
The analysis of pesticide residues in frozen vegetables is a critical aspect of ensuring food safety and compliance with international standards. The use of pesticides on crops can lead to contamination if not controlled properly, posing risks to human health. ISO 46222 provides a harmonized approach for the determination of pesticide residues by gas chromatography-mass spectrometry (GC-MS).
This service involves meticulous sample preparation and analysis using state-of-the-art instrumentation. The process begins with the collection of representative samples from frozen vegetable products, which are then ground into fine particles to ensure homogeneity. Pre-treatment steps include extraction using appropriate solvents followed by clean-up techniques like solid-phase extraction (SPE) or liquid-liquid partitioning.
Following sample preparation, analysis is carried out on a GC-MS system that allows for the identification and quantification of various pesticides down to very low levels. The analytical method ensures high sensitivity and selectivity necessary for detecting trace amounts of residues. It's important to note that the choice of extraction solvent, clean-up procedure, and instrument settings play crucial roles in achieving accurate results.
The acceptance criteria stipulated by ISO 46222 include limits set for individual pesticide residues based on acceptable daily intake (ADI) values established by relevant health authorities. Compliance with these limits is essential to prevent adverse effects on consumers. The testing process also considers the matrix effect of frozen vegetables, which can impact analytical performance.
Our laboratory adheres strictly to ISO 46222 guidelines throughout every stage of residue analysis. This includes rigorous quality control measures and proficiency testing programs that validate our methods against recognized standards. Our team of experts ensures thorough documentation and reporting aligned with the requirements outlined in the standard. By providing precise data on pesticide residues, we help clients ensure their products meet stringent regulatory requirements.
For accurate interpretation of results, it's vital to understand how different factors influence test outcomes. Variables such as sample handling, storage conditions, and equipment calibration can significantly affect analytical precision. Our experienced staff ensures consistent quality through standardized procedures and continuous training aimed at maintaining proficiency in current methods.
The importance of ISO 46222 cannot be overstated when it comes to protecting public health by preventing harmful pesticide residues from entering the food supply chain. By offering this specialized service, we contribute significantly towards enhancing safety standards across various sectors including agriculture, retail, and manufacturing.

Scope and Methodology
The scope of our service encompasses the comprehensive analysis of pesticide residues in frozen vegetable samples according to ISO 46222. This includes identifying and quantifying specific pesticides present at trace levels within these products.
To achieve reliable results, we follow a structured approach that involves several key steps:
- Sample Collection: Representative samples are collected from frozen vegetable batches ensuring they reflect the overall quality and safety characteristics of the product.
- Preparation: The collected samples undergo thorough grinding to achieve uniform particle size suitable for subsequent processing. Extraction solvents like methanol or acetone may be used depending on the nature of pesticides being targeted.
- Cleanup: After extraction, SPE cartridges are utilized to remove interfering compounds leaving behind pure residues ready for analysis.
- Analytical Procedure: The cleaned extracts are injected into a GC-MS instrument configured according to ISO 46222. This enables differentiation between target pesticides and background noise allowing accurate quantification.
The methodology employed allows for the detection of multiple pesticides simultaneously providing valuable information regarding potential contamination risks. Our experienced technicians ensure each step adheres strictly to ISO 46222 requirements ensuring consistent and repeatable results.
Industry Applications
- Agriculture: Monitoring pesticide use in growing crops helps maintain product quality while minimizing health risks associated with overuse.
- Retail: Ensuring frozen vegetable products meet regulatory standards ensures consumer confidence and protects brand reputation.
- Manufacturing: Analyzing raw materials used in processing aids in maintaining consistent product specifications.
Our services play a crucial role in safeguarding public health by verifying that frozen vegetables comply with international safety standards. This is particularly important given the increasing demand for organic and non-GMO products where consumers seek assurance regarding the absence of harmful pesticides.
