Short Bio

Henryk Jeleń is a full professor of food chemistry at the Faculty of Food Science and Nutrition, Poznań University of Life Sciences since 2007. He received his PhD (1996) and habilitation (2002) in food science, specializing in food chemistry. Has spent his postdoc in University of Minnesota, at Chester Mirocha Lab. He is a member of Polish Academy of Sciences. His scientific interests are related mainly to flavor chemistry and food aroma compounds analysis using hyphenated techniques (GC-O, GC-MS, GCxGC-MS), also profiling volatile compounds for authenticity testing and monitoring changes in food products. He is also interested in sample preparation techniques in flavor/volatile compounds analysis, especially solventless approaches. He authored over 120 peer-reviewed scientific publications, 15 book chapters and edited a book on food flavors.

COLD PRESSED OILS – A SENSORY FEAST FOR CONSUMERS AND A CHALLENGE FOR ANALYTICAL AND FLAVOR CHEMISTS

Henryk Jeleń, Anna Gaca, Małgorzata Majcher

Cold pressed oils are produced from oil-rich plants seeds using pressing at low temperature, therefore the final product is rich in bioactive constituents, and retains the characteristic flavour of the raw material. They are getting more popular among consumers not only due to their nutritional value, but also to their unique flavour. The complexity of their flavour is the result of seeds composition, very often seeds pre-processing, such as roasting and changes undergoing in oils in a result of unsaturated fatty acids reactivity.
Compounds that are responsible for the unique flavour of these oils – key odorants – require specific methods for their identification and quantitation involving gas chromatography – olfactometry (GC-O) and gas chromatography – mass spectrometry (GC-MS). This approach allows for the identification among hundreds of volatiles these compounds that are important in creation of flavour of these oils. On the other hand volatile compounds may provide useful information for the authenticity assessment of oils, their botanical origin, as well as markers of the technological processes and quality changes during oils storage.
The lecture will be focused on challenges in identification of compounds responsible for flavour of cold pressed rapeseed and argan oils, as well as the use of volatile compounds of different cold pressed oils for their differentiation, and quality testing.
