1. Extraction with organic solvents of different polarity: 2. Distillation techniques: o Steam distillation distillation: Clevenger and Deryng devices. Simultaneous distillation-extraction: Likens Nickerson equipment. O Vacuum distillation. Head space techniques: o Dynamic head space: intact fruits. O HS-SPME (solid phase microextraction for headspace). SPME (solid phase microextraction). 4. Evaluation of the creation of artifacts during the extraction process. Practical sessions: - Extraction of volatile compounds with Deryng apparatus and analysis by GC-MS, and Likens-Nickerson and analysis by GC-MS.- Extraction of volatile compounds with HS -SME and by vacuum distillation, and analysis by GC-MS.
