Natural Aromatic Raw Materials: Production

- Terms and Definitions of Natural Raw Materials (ISO/TC54 Standard “Essential Oils”) 

- Methods for extracting volatile compounds: production of essential oils, extraction of flavor compounds, supercritical CO₂ extraction, the ESAM process, VMHD extraction, headspace extraction techniques, SPME…
- Characterization of volatile compounds: Gas Chromatography (GC), Ultra-Fast Gas Chromatography (UFGC), Flame Ionization Detector (FID), Gas Chromatography-Mass Spectrometry (GC-MS), GC-FTIR, Comprehensive Two-Dimensional Gas Chromatography (GC-GC), chiral chromatographic analysis, GC-olfactometry, electronic nose.
