Rehydration of pumpkin cubes (Cucurbita moschata Duch) dried by convection.

Abstract

The rehydration behavior at 100 ± 2 °C with a solid:liquid ratio (m/m) of 1:100 for pumpkin cubes dehydrated by convective drying was determined by the Peleg model. The rehydration of the pumpkin cubes dehydrated by convection at 50, 60 and 70 °C had a good fit to the Peleg model, with the pumpkin cubes dried at 60 °C presenting the best fit. The volume of the dice increased over the rehydration time until it recovered its initial volume of 1 cm³.
