抄録

A method for measuring the spectra of the ¹H-NMR of localized region on an image of a food material was devised using a spectrometer (JEOL GSX-270 WB) and its microimaging system. The spin-echo two-dimensional FT method was used for the measurements. The slice thickness of a sample was regulated by a copper cover with a 1.5 mm slit in the sample holder. The area on the X-axis was restricted by selective excitation under an X-axis gradient magnetic field. The position on the Y-axis was selected after FT of the spectral data incorporated with phase encoding. The spectra in areas of 0.3 mm × 0.05 mm on the ¹H-NMR image were obtainable by this method. The localized spectra of sausages made of three different materials and processes were measured in order to discuss their tissue structures.
