Storage induced changes of potato properties as detected by DMA

Popis výsledku v původním jazyce

Dynamic mechanical analysis (DMA) was applied to the potato tissues ('cortex', 'pith', and 'side' surface) of two long stored (more than five months) cultivars: waxy 'Nicola' and more mealy 'Saturna') in the temperature range 30-90 oC and constant air relative humidity of 90 %. The results were compared with those obtained at the same cultivars and their parts about one month after harvest. The DMA scans showed the differences of the two cultivars and the effect of storage mainly on the area of the "starch" peak. The "starch" peak was shifted due to storage to lower and higher temperatures for 'Nicola' and 'Saturna', respectively. The "starch" peaks are asymmetric. High and stable (not influenced by storage) asymmetry was observed in 'Saturna'. The asymmetry was discussed as an indication of long-time internal cellular stresses that could lead to the potato sloughing. On the other hand, the "starch" peak asymmetry was much lower in 'Nicola'. During storage, this asymmetry was reduced o
