CHARACTERIZATION and COMPARISON of TURKISH TABLE OLIVE VARIETIES with NMR RELAXOMETRY and MAGNETIC RESONANCE IMAGING

Abstract

Olive is one of the fruits that is mostly consumed in the Mediterranean region. Depending on thevariety, oil quality of the olive changes significantly. In this study, Nuclear Magnetic Resonance (NMR),Relaxometry and Magnetic Resonance Imaging (MRI) experiments were used to characterize differentTurkish table olive varieties, (Ayvalik, Mega, Sele, Light) in terms of tissue structure, fat and water contents.Moisture and fat content were measured using an infrared moisture analyzer and soxhlet extraction,respectively. NMR Relaxometry and MRI experiments were performed with a 0.32 T and 3T system,respectively. Longitudinal relaxation time (T1) and transverse relaxation time (T2) signals were acquired.Furthermore, non-negative least square (NNLS) method was implemented to T2 decay curves to investigatewater and oil distributions. Turbo Spin Echo sequence with fat and water suppression was used forMRI experiments. Significant correlation existed between the physical measurements and NMR relaxationtimes
