This result could be due to the fact that a higher temperature of drying creates a more rigid structure and, in
consequence, produces the collapse of channels for water
uptake. As a result, a smaller rehydration rate could happen.
The capacity of water uptake during rehydration can be
quantified by RR and COR indexes. Values of COR and RR for
pineapple samples with 2h of rehydration are detailed in
Table 3. These coefficients are expressed as the average of
results ofthree independent drying-rehydration tests
