This study for the first time reports the combined use of low-field nuclear magnetic resonance (LF-NMR) and confocal laser scanning
microscopy (CLSM) in the study of the effects of salting on low and high dry matter (DM) potato tissue. The simultaneous use of CLSM
and NMR resulted in important information in relation to the interpretation of the origin of the NMR water populations. Salting caused
the raw potato cells to loose weight, which in the microscopic images was observed as loss of turgor pressure still further away from the
edges of the samples with increased salting time. The total water loss after salting was lowest for high DM potatoes. The LF-NMR
analyses revealed that this could be ascribed to a faster T2 relaxation time of the cytoplasmatic and extracellular water and thus to water
being more restricted in high DM potatoes. In addition, a tendency to a faster T2 relaxation time was observed for both low and high
DM potatoes with increasing salting time, which reveals a salt-induced restriction of the cytoplasmatic and extracellular water
population. The paper illustrates the
