Marta Gratac6s-Cubarsi Girona, 28 de gener de 2020 The doctoral thesis presented herein was developed in the framework of the Strategic Plan of the National Institute for Agricultural and Food Research and Technology (INIA) and agrifood research in Spain of the State Secretariat of Research, Development, and Innovation of the Ministry of Economy and Competitiveness, through the subvention of the project RTA2011-00123-00-00 and an FPI-INIA grant. Acknowledgments The beginning of this thesis, as it could not be otherwise, shall address one important last duty. I sincerely thank everyone who helped me get here, one way or another. First of all, to my thesis directors, Dr. Maria Hortós Bahí and Dr. Marta Gratacós-Cubarsí for their continuous support, availability and knowledge over all these years and, most of all, for the opportunity to be part of their team. Besides my thesis directors, I want to thank Dr. Luis Guerrero Asorey for his valuable help, dedication, and encouragement at all times of this research work. To my tutor at the University of Girona, Dr. Carmen Carretero Romay, for her understanding and assistance during this journey. To the National Institute for Agricultural and Food Research and Technology (INIA) for the grant conceded and the administrative support. To the Institute of Agrifood Research and Technology (IRTA) for the opportunity to conduct this work, as well as to the Center for Research in Agricultural Genomics (CRAG) and the Mas Badia research experimental station for their assistance and fruit breeding. To Prof. Saskia van Ruth and Dr. Yannick Weesepoel of the Authenticity and Bioassays research unit, of the Wageningen Food Safety Research, part of Wageningen University & Research, for welcoming me in The Netherlands to develop a very important part of my research concerning the analysis of volatile organic compounds, as well as for their valuable help and knowledge. To Dr. Anna Claret, Dr. Jason Argyrirs, Dr. Jordi Garcia-Mas, Mr. Alex Koot, Dr. Iban Eduardo, and Dr. Ignasi Iglesias, the coauthors of the publications comprising this thesis, for their involvement and insightful comments. I would also like to thank Mr. Narcis Sais for his help and companionship in the laboratory over the years. i To Dr. Didier Dupont and Dr. Juliane Floury for welcoming me to the Science and Technology of Milk and Eggs research unit, of the French National Institute of Agricultural Research (INRA). During this journey, I had the opportunity to be involved in other research activities. Although these are out of the scope of the present thesis, I would still like to thank them and their team for their patience and knowledge. To my colleagues Raquel, Francesc, Anna, Kathi, Maria, Luis for their companionship and so many shared moments. Also, Linda, Fanny, Mabelyn, Ning, and Melanie for their kindness during my time in Rennes, as well as Valentina, Isabelle, Jing, Yuzheng, Ningjing, Hector, Sara, and Daniel during my time in Wageningen. Finally, I would like to thank my family and friends for their constant support in my life even if I am far away, especially my mother Lourdes who taught me that "knowledge does not take place". To Gerard for his infinite patience and understanding.
