Résumé

A cryogenic micro-slicer spectral imaging system has been developed to analyse the morphological characteristics of biological materials frozen in cryogenic treatment using near-infrared spectroscopic as well as reconstructed 3-D images. Structural parameters of ice crystals formed in raw beef and diluted agar solutions (1 %wt.) were measured at temperatures of -15 and -120°C. Frozen samples were sliced with a thickness of 1.0 µm to capture an exposed cross-section by near-infrared imaging at the wavelength of 1025 nm. The results indicated that spectroscopic images of ice crystals were successfully visualized, as distinct from those of other constituents.
