This thesis explores the process of essential oil extraction from citrus fruits, with a particular focus on Citrus latifolia Tanaka (Tahiti lime), using steam distillation techniques. The research was carried out at the laboratory of the Research Center for Agroindustrial Production and Circular Economy (CIPAEC), located in the municipality of Santa Barbara, in the department of Antioquia, Colombia, where I personally oversaw all operational phasesfrom the preparation of the raw material to the refinement of the final product. Four distillation cycles were performed, each time assessing the yield and the operating conditions of the process. The extracted samples were analyzed using gas chromatography coupled with mass spectrometry (GC-MS), and the resulting data were processed through multivariate statistical analysis (PCA) to highlight differences betweenthe various chemical profiles. Beyond the technical aspects, the work also reflects on the potential valorization of citrus peels, often treated as waste, within a framework of circular economy and sustainability.
La tesi approfondisce il processo di estrazione degli oli essenziali dagli agrumi, con particolare riferimento al Citrus latifolia Tanaka (lime di Tahiti), attraverso la tecnica della distillazione in corrente di vapore. La ricerca è stata condotta all’interno del laboratorio del Centro di ricerca sulla produzione agroindustriale e sull'economia circolare (CIPAEC), nel comune di Santa Barbara, nel dipartimento di Antioquia, in Colombia, dove ho seguito personalmente tutte le fasi operative: dalla preparazione della materia prima fino alla raffinazione del prodotto. Sono stati eseguiti quattro cicli di distillazione, valutando ogni volta la resa e le condizioni del processo. I campioni ottenuti sono stati sottoposti ad analisi mediante gascromatografia accoppiata a spettrometria di massa (GC-MS), con successiva elaborazione dei dati tramite analisi statistica multivariata (PCA), per mettere in evidenza le differenze tra i vari profili chimici. Oltre agli aspetti tecnici, il lavoro riflette sul potenziale di valorizzazione delle scorze di agrumi, spesso considerate scarti, in un’ottica di economia circolare e sostenibilità.

Abstract
This thesis explores the process of essential oil extraction from citrus fruits, with a particular focus on Citrus latifolia Tanaka (Tahiti lime), using steam distillation techniques. The research was carried out at the laboratory of the Research Center for Agroindustrial Production and Circular Economy (CIPAEC), located in the municipality of Santa Barbara, in the department of Antioquia, Colombia, where I personally oversaw all operational phasesfrom the preparation of the raw material to the refinement of the final product. Four distillation cycles were performed, each time assessing the yield and the operating conditions of the process. The extracted samples were analyzed using gas chromatography coupled with mass spectrometry (GC-MS), and the resulting data were processed through multivariate statistical analysis (PCA) to highlight differences betweenthe various chemical profiles. Beyond the technical aspects, the work also reflects on the potential valorization of citrus peels, often treated as waste, within a framework of circular economy and sustainability.| File | Dimensione | Formato | |
