This article describes a new monitoring technology for scanning rheological properties of tuber tissue during heating. The experiments done on low solids tubers of cv. Magda showed that the maximum thermoelectric effect was obtained at about 60 deg C in the temperature region where the gelatinisation process of intra-cellular starch starts and some few cell disruptions occur.
