Effect of convective drying on total anthocyanin content, antioxidant activity and cell morphometric parameters of strawberry parenchymal tissue (Fragaria x ananassa Dutch)

The effect of convective drying of strawberries (Fragaria x ananassa Dutch) on the contents of anthocyanins (AcyTot) and antioxidant capacity (TEAC), as equivalents of Trolox, was evaluated as well as its relation to cell morphological changes in the mesocarp by means of determining the variations in Area (A), Perimeter (P), Feret Diameter (Fe) and Fractal Dimension of parenchymal tissue cells. A decrease in anthocyanin content caused by drying at 60, 70 80 and 90 °C and 1 m/s airflow was observed. ACyTot and TEAC showed correlation (r = 0.784). The decrease in ACyTot and TEAC in samples dehyd... Mehr ...
