The presence of microplastics in food matrices represents an emerging issue that requires reliable analytical methodologies for their identification and characterization. The complexity of food matrices and the small size of the particles demand techniques capable of providing high chemical selectivity and adequate spatial resolution. This thesis examines the main analytical approaches used for the study of microplastics in food, with particular focus on Fourier-transform infrared spectroscopy (FT-IR).

La presenza di microplastiche nelle matrici alimentari rappresenta una problematica emergente che richiede metodologie analitiche affidabili per la loro identificazione e caratterizzazione. La complessità delle matrici e le ridotte dimensioni delle particelle rendono necessarie tecniche in grado di garantire elevata selettività chimica e adeguata risoluzione spaziale. Il presente elaborato analizza i principali approcci analitici per lo studio delle microplastiche negli alimenti, con particolare attenzione alla spettroscopia infrarossa in trasformata di Fourier (FT-IR). In particolare, viene approfondita la micro-FT-IR (μFT-IR), evidenziandone principi di funzionamento, modalità operative, vantaggi e limiti applicativi. La μFT-IR emerge come una tecnica di riferimento per l’identificazione delle microplastiche, grazie alla sua capacità di coniugare analisi chimica e risoluzione micrometrica.

Abstract
The presence of microplastics in food matrices represents an emerging issue that requires reliable analytical methodologies for their identification and characterization. The complexity of food matrices and the small size of the particles demand techniques capable of providing high chemical selectivity and adequate spatial resolution. This thesis examines the main analytical approaches used for the study of microplastics in food, with particular focus on Fourier-transform infrared spectroscopy (FT-IR). Special attention is given to micro-FT-IR (μFT-IR), highlighting its operating principles, measurement modes, advantages, and limitations. μFT-IR emerges as a reference technique for microplastics identification, due to its ability to combine chemical analysis with micrometric spatial resolution.| File | Dimensione | Formato | |
