ISO 70691 Multi-Class Drug Residue Analysis in Functional Foods
The ISO 70691 standard provides a comprehensive framework for the analysis of multi-class drug residues in functional foods. This service is essential for ensuring food safety and compliance with international standards, particularly relevant to quality managers, compliance officers, R&D engineers, and procurement specialists.
Functional foods are designed to provide additional benefits beyond basic nutrition, such as health-promoting properties or disease prevention. These products often require rigorous testing to ensure they meet stringent regulatory requirements regarding drug residue levels. The ISO 70691 standard allows for the detection of a wide range of drugs that might be inadvertently introduced into functional foods during processing, packaging, or storage.
The process involves several critical steps:
- Sampling: Representative samples are taken from various batches to ensure variability is accounted for.
- Sample preparation: This step includes homogenization and extraction methods tailored to the specific matrix of the food sample.
- Instrumentation: High-performance liquid chromatography (HPLC) coupled with tandem mass spectrometry (LC/MS/MS) is typically used to identify and quantify residues accurately.
- Data analysis: Advanced software tools are employed to interpret results, ensuring precise identification and quantification of each residue detected.
The standard also emphasizes the importance of method validation, which includes linearity, precision, accuracy, recovery rates, limit of detection (LOD), and limit of quantitation (LoQ). These parameters ensure that the analytical methods used are reliable and reproducible across different laboratories.
By adhering to ISO 70691, food manufacturers can demonstrate compliance with international standards, thereby enhancing consumer confidence and ensuring product safety. This service is particularly valuable for companies involved in the development of functional foods, as it helps them maintain high-quality standards and avoid potential legal issues associated with non-compliance.
| Drug Classes | Detection Limits (µg/kg) |
|---|---|
| Beta-lactams | <10 |
| Tetracyclines | <50 |
| Sulfonamides | <20 |
| Macrolides | <10 |
| Sample Types | Preparation Methodologies | Target Drug Classes |
|---|---|---|
| Fruit Juices | Pasteurization followed by extraction with methanol | Beta-lactams, Tetracyclines, Sulfonamides |
| Functional Bars | Grinding and solvent extraction | Macrolides, Beta-lactams, Quinolones |
| Dairy Products | Solid-phase extraction (SPE) using alumina | Tetracyclines, Fluoroquinolones |
The ISO 70691 standard ensures that all tests are conducted with the highest level of accuracy and precision. This is crucial for maintaining product integrity and ensuring that functional foods meet both regulatory and consumer expectations.
