To whom I address my sincere thanks and gratitude for their scientific advice and encouragement. Thank you from the bottom of my heart for directing me throughout this thesis. Never to mention your support and, above all, your confidence in me. My respectful gratitude to CNRS-Lebanon and Lebanese University (UL) for their financial support throughout the whole Ph.D. program. I would like to thank the ABIES Doctoral School and its director Dr. Alexandre Perry and the EDST doctoral school, and its Dean, Dr. Omar Fawaz. Without them, my journey as a Ph.D. candidate wouldn’t be possible. My thanks go to the jury members Dr. Nathalie Dupuy, Dr. Imad Toufeili, Dr. Olivier Donard, and Dr. Jérôme Vial, for giving the time to criticize and improve my work and for accepting to be members of the defense committee. I won’t forget my thesis committee, which accompanied me throughout the work. My sincere thanks to Dr. Rita Yaacouub and Dr. Luc Eveleigh for granting their time and assistance in realizing this work. Thank you for always being there to help me and for answering my questions. I express my deep gratitude to Dr. Ali Toufeil, Dr. Audrey Solgadi and Dr. Milad Riyachi. Thank you for welcoming me to the SAMM and LARI Laboratories and for giving the time to pass on the knowledge of spectroscopy, chromatography and olive oil extraction. My thanks also go to Dr. Jad Rizkalah for providing me with his knowledge of statistical studies and MATLAB software. Thank you for offering your help, answer my questions, and for all the advice over the years. I would also like to thank all the laboratory members and assistants, particularly Mrs. Nathalie Locquet and Mr. Ghassan Menhem, for their technical assistance. A big thank you to the AgroParisTech team, Prof. Douglas Rutledge, Dr. Delphine Bouveresse, Roberto Garcia, Yann Padellec, Camille Cassin, and Dr.Hervé This.
