Broad line NMR and high resolution NMR signals of water proton contained in fresh and dehydrated fish muscle were observed. The broad line NMR signal did not give the detail physical states of water.
The line width of fresh muscle under high resolution NMR spectroscopy was 3cps, which differs from that of pure water. Water proton in fish muscle gives a much broader and unsymmetric sygnal in progress of dehydration.
The meaning of these finding will be explained by further researches however, the results demonstrate that the water in fish muscle is a possible heterogenity.
