BOOK OF ABSTRACTS - 3rd International Symposium on RECENT ADVANCES IN FOOD ANALYSIS (RAFA)

Importance of the Topic

The 3rd International Symposium on Recent Advances in Food Analysis convened leading experts to address critical needs in modern food quality and safety control. As global food production and regulatory demands intensify, cutting-edge analytical methods are essential to detect contaminants, verify authenticity, and optimize nutritional value.

Goals and Overview of the Proceedings

The symposium’s objective was to survey and disseminate state-of-the-art techniques spanning chromatography, mass spectrometry, sensors, immunoassays, molecular biology, and emerging microfluidic platforms. Organized into oral and poster sessions, key themes included environmental contaminants, mycotoxins, pesticide residues, drug and veterinary residues, allergens, flavor profiling, authenticity testing, packaging migrants, and bioactive nutrients.

Methodology and Instrumentation

Contributions demonstrated rigorous validation of multi-residue and target screening approaches. Sample preparation protocols employed QuEChERS, solid-phase extraction, immunoaffinity cleanup, pressurized liquid extraction, and coacervative extraction. Separation and detection techniques encompassed:

• Gas chromatography with single-quadrupole, triple-quadrupole, time-of-flight, and GC×GC platforms
• Liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS), quadrupole-time-of-flight (QTOF) and ion traps
• Capillary electrophoresis with on-line concentration and MS detection
• Electrochemical immunosensors, optical biosensors (SPR, OWLS), and electronic noses
• Polymerase chain reaction and padlock-ligation assays for GMO and pathogen detection
• Microfabricated fluidic lab-on-a-chip devices and ambient ionization MS (DESI, DART)

Main Results and Discussion

Researchers reported ultra-low detection limits, enhanced accuracy, and high throughput for trace contaminants including masked mycotoxins, pesticide and veterinary drug residues, heavy metals, persistent organic pollutants, and packaging migrants. Novel applications of 2D GC, high-resolution TOF-MS, and isotope-dilution methods enabled reliable quantitation of advanced glycation end-products, acrylamide, furan, and complex lipid markers. Immuno- and DNA-based assays offered rapid on-site screening of allergens and GMOs. Microchips and ambient MS imaging opened avenues for real-time mapping of bioactive compounds and food fraud markers.

Benefits and Practical Applications

These advances equip laboratories, regulatory bodies, and industry with robust tools to:

• Ensure compliance with tightening maximum residue limits
• Protect consumer health by early detection of emerging toxins
• Authenticate origin and detect adulteration of high-value products
• Monitor processing-induced contaminants and optimize manufacturing
• Support quality assurance in supply chains through portable, rapid assays

Future Trends and Potential Uses

The field is poised for integration of high-resolution, data-rich MS with chemometrics and machine learning for non-targeted screening and predictive risk assessment. Emerging priorities include:

• Miniaturized, automated lab-on-a-chip platforms for point-of-need testing
• Multiplexed biosensors combining optical, electrochemical, and molecular recognition elements
• Ambient and direct MS imaging for spatially resolved profiling in intact foods
• Development of certified reference materials for new analytes
• Standardization of methods and interlaboratory validation networks

Conclusion

The symposium underscored remarkable progress in analytical science, driven by collaborations across academia, industry, and regulatory agencies. Continued investment in method development, validation, and training will be vital to safeguard food supplies, meet consumer expectations, and address future safety challenges.
