PROGRAM - 9th International Symposium on RECENT ADVANCES IN FOOD ANALYSIS (RAFA)

Significance of Recent Advances in Food Analysis Symposium

The 9th International Symposium on Recent Advances in Food Analysis (RAFA 2019) brought together leading experts to address the growing need for more precise, rapid and comprehensive techniques in food safety, quality, authenticity and nutritional analysis. Advances in analytical chemistry are essential to protect public health, ensure regulatory compliance and maintain consumer trust in an increasingly complex global food supply chain.

Symposium Objectives and Overview

RAFA 2019 aimed to:

• Present cutting-edge developments in food contaminant detection, natural toxin profiling and metabolomics
• Explore novel approaches to food authentication and fraud prevention
• Share best practices for pesticide and veterinary drug residue analysis
• Discuss emerging techniques for on-site and citizen-science testing
• Foster collaboration between EU and Chinese food safety laboratories

The four-day program featured plenary lectures, parallel oral sessions on natural toxins, authenticity, processing contaminants, residues and omics, vendor seminars, workshops and poster sessions covering over 300 contributions.

Methodologies and Instrumentation

The symposium highlighted a broad range of analytical platforms, including:

• High-resolution mass spectrometry (LC-HRMS, GC×GC-TOF, Orbitrap) for non-targeted screening
• Triple-quadrupole MS/MS for sensitive quantification of multi-class residues
• Vibrational spectroscopy (NIR, Raman) and chemometrics for rapid authenticity testing
• Ambient ionization (DART-MS, REIMS) for minimal sample prep
• Microextraction and automated SPE/QuEChERS for streamlined cleanup
• Ion mobility separation to resolve isomers in complex matrices
• DNA-based PCR and sequencing techniques for species identification
• Lateral flow assays, ELISA and microarray immunoassays for field-deployable allergen and mycotoxin screening
• Fluorescence, electrochemical and smartphone-based biosensors for point-of-need testing
• Stable isotope analysis (EA-IRMS) for geographical origin authentication

Key Findings and Discussion

Speakers emphasized the superiority of high-resolution full-scan approaches in detecting emerging contaminants and masked toxins. Novel rapid workflows combining chemometrics with handheld spectrometers or coated blade spray were shown to deliver reliable on-site screening results. Advances in multi-omics and metabolomics enabled deeper insights into food composition, adulteration markers and the human exposome. Harmonized methods and proficiency testing by EU Reference Laboratories were identified as critical for regulatory consistency.

Practical Benefits and Applications

These analytical advances enable industry and regulators to:

• Detect food fraud and adulteration more rapidly and accurately
• Monitor contaminant levels (pesticides, mycotoxins, processing hazards) with greater sensitivity
• Authenticate origin and quality claims to protect premium brands
• Implement near-real-time, on-site testing to reduce lab turnaround times
• Apply scores of new biomarkers for nutritional and safety assessments

Future Trends and Opportunities

Emerging directions discussed include:

• Expanded use of artificial intelligence and machine learning in spectral data interpretation
• Miniaturized and integrated portable platforms combining multi-modal sensors
• Blockchain and digital traceability systems for secure supply-chain data
• Next-generation sequencing for complex matrix authentication
• Increased emphasis on human biomonitoring and exposome profiling
• Metrology frameworks (METROFOOD-RI, FoodFortress) to validate novel methods

Conclusion

RAFA 2019 underscored the critical role of innovative analytical chemistry in safeguarding food integrity and public health. The symposium fostered cross-disciplinary collaboration and set the stage for the next generation of robust, high-throughput and field-deployable food analysis solutions.
