  • Simultaneous evaluation of antioxidant activity and morphological changes during drying of strawberry are reported.

  • Drying temperatures higher than 60 °C did not have different effects on the changes of cell morphology of the tissue.

  • Drying temperatures higher than 60 °C influenced in a different magnitude the anthocyanin content and the antioxidant activity of strawberry.

  • Cell disruption is not necessarily related to antioxidant activity when temperatures are higher than 60 °C.

  • Changes in antioxidant activity seems to be primarily due to dehydration than cell deformation.
