Natural aromatic raw materials: extraction

- Terms and definitions of natural raw materials (ISO/TC54 "Essential oils" standard) 

- Methods for extracting volatile components: obtaining essential oils, extracting aromas, supercritical CO2 extraction, ESAM process, VMHD extraction, headspace extraction techniques, SPME, etc.
- Characterization of volatile components: 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.

Hourly volumes:

CM: 12 p.m.

Practical work: 8 hours

Knowledge of the origin, natural occurrence, extraction conditions, and characterization of the volatile fraction of aromatic plants (essential oils) and aromas.

Experimental training: Application of theoretical knowledge on the extraction of aromas and essential oils and their characterization.
