Outline of Final Research Achievements

I developed a method to determine the damage of a cell and the tissues of vegetables in heating and freezing by diffusion measurement of the intracellular water by NMR and examined relations of cell damage and the softening in the root crops such as potatoes using it. When cell damage progressed by heating and freezing, diffusion of the water changed from restricted diffusion to free diffusion accordingly and it must be good method to evaluate degree of cell damage. I examined the freezing method using the supercooling of cell water to prevent softening after freezing, and it was shown that there was a big effect with a potato and a sweet potato.
