Résumé :
|
The distribution of water proton transverse relaxation times is used to monitor the amount and subcellar distribution of non-freezing water and ice in potato tissue. At subzero temperatures most of the non-freezing water is found to be associated with starch granules and cell wall material, and the amount of unfrozen water at each temperature has been determined. The potential of NMR relaxation techniques in food cryopreservation is discussed.
