Abstract

Magnetic resonance imaging (MRI) and localized proton MR spectroscopy (MRS) techniques have been applied for studying different maturation processes in the histochemistry of coconut (Cocos nucifera). Images of the tender and mature coconut are characterized by protons of the aqueous solution present in the cavity and from the surrounding pulp, whereas the image of the dry coconut is from the protons of the fat present in the pulp. Localized proton MR spectra of the water present in the cavity from the tender and the mature coconut show several resonances due to different chemical constituents of coconut water, whereas typical spectra of the pulp from dry coconut reveal a profile of the hydrogens present in the saturated and unsaturated fatty acid chains. In addition, images obtained from a rancid coconut show the extent of internal damage and degradation due to fungal growth; the corresponding localized MR spectra of the coconut water reveal that several proton resonances are absent.
