Flavor and Fragrance Virtual Users' Workshop: Day 2

Gain insight from our presentations that are focused on everyday analytical challenges with non-targeted fragrance and flavor applications. Following the speakers sessions, you are invited to interact with our application chemists and engineers who will be available to provide guidance and expertise for all your hardware, software, and application related questions. Please make sure to bring your questions or submit them when you sign up. We hope to see you there!

Day 2

18:30 – 18:55 (CEST) Routine simultaneous quantification of 61 allergens in fragrance raw materials by a GC×GC-qMS method

Abstract: Quantifying allergens in fragrances is a novel challenge where development in methods is needed to increase speed, reliability, and quality. This presentation looks at the analysis of 64 fragrance allergens using bi-dimensional gas chromatography hyphenated with mass spectrometry and a flame ionization detector. This work developed a quantification method for fragrance allergens using GCxGC-MS/FID that allows quantification of a wide variety of allergens in a single run without the need for sample dilutions, multiple injections and obtains reliable and robust results.

18:55 – 19:25 (CEST) State-of-the-art Sample preparation techniques for Flavor Analysis: New Trends Towards more Automation, Miniaturization and Solventless Sample Preparation Techniques

Abstract: Food and beverage companies rely on accurate and detailed aroma profiling to deliver high-quality products with consistent key flavour compound profiles and to develop new products. Quality and reliability of aroma analysis by capillary gas chromatography (GC) is greatly affected by the applied sample preparation technique. Conventional solvent-based extraction techniques can now be miniaturized and automated, but still suffer sometimes from severe matrix contamination resulting in poor chromatographic performance. New GC technologies can be implemented to avoid such matrix influence on performance.

Solvent-based extraction techniques are also increasingly being replaced by solventless techniques, such as dynamic headspace sampling (DHS), which is suitable for the characterization of aromas in food and beverages. The technique can also be fully automated and delivers full aroma profiling covering a wide volatility range due to less selectivity than other headspace enrichment techniques. Besides the principle of DHS, the flexibility of working in different DHS modes and the high sensitivity that can be reached with DHS enrichment, it will be shown how to successfully implement DHS for aroma profiling purposes depending on the type of food matrix and the volatility range that needs to be covered

Presenter: Christophe Devos (Senior Scientist / Project Manager, RIC Technologies Group)

19:25 – 20:00 (CEST) Panel Discussion

Presenter: Emilie Belhassen (Analytical Scientist, Firmenich SA, Switzerland)

Emilie Belhassen is currently an analytical scientist at Firmenich in Switzerland. She obtained her PhD in 2014 from the University of Nice working on oderants analysis using two-dimensional GC techniques and subsequently joined Firmenich as a post-doctoral researcher working on fragrance allergens.

Presenter: Christophe Devos (Senior Scientist / Project Manager, RIC Technologies Group)

Christophe Devos received his Ph.D. degree in Analytical Chemistry in 2007 from the Ghent University. During his Ph.D study he developed analytical methods for ultra-trace analysis of organometallic compounds in environmental samples that he then applied in a laboratory complying under GMP regulation. He then joined the Research Institute for Chromatography (RIC group), Kortrijk, Belgium in 2005where he initially was involved in the development and automation of novel sample preparation methods for gas chromatographic analysis. He presently occupies the position of Senior Scientist / Project Manager within the RIC Technologies group developing and supporting new analytical solutions and important market applications.
