This paper presents the characteristics of potato and apple tissues, with/out electroporation, by Time Domain-Nuclear Magnetic Resonance (TD-NMR). A portable TD-NMR was used to measure the proton relaxation time, T2, and the changes in the cells due to molecular water mobility of potato tubers,-NMR to identify the modifications that occurred at the cell level involving water molecules mobility in potato tubers and apple tissues after the electroporation treatment and compared with non-electroporated ones. The comparisons with normal potato and apple tissue and preliminary measurements in bulk were performed. Samples were also analyzed in terms of conductivity of the tissue and microscopic morphology. The results indicate that the electroporation process effect is identified with a variation of the peak position in T2 distribution, associated with sub-cell modifications.

AbstractThe migration of bound water and free water has been investigated during microwave drying of wood by the time domain nuclear magnetic resonance (TD-NMR) technique. Both the heartwood (hW) and sapwood (sW) of Beijing poplar (Populus beijingensisW. Y. Hsu) and Qingpi poplar (Populus platyphyllaT. Y. Sun) were studied. The microwave drying is characterized by a fast drying rate, and there is a linear relation between moisture content (MC) and microwave drying time (t). The drying rate of free water is about 2.7 times more rapid than that of bound water. The spin-spin relaxation time (T2) revealed that most of the water was free water situated in smaller pores. The irregular T2 signal amplitudes of free water in hWs indicated that fractional water in smaller pores was transferred into bigger pores during drying.
