Results after six hours of osmotic dehydration of
pineapple half-slices at 30, 40 and 50ºC in a
hypertonic sucrose solution showed that solute
content was a linear function of the water content
in the pineapple fruit during osmotic dehydration
and this ratio was independent of temperature.
Nevertheless, the rate to which the final ratio s/w
was reached increased with temperature. These
results correlated well to the ratio of diffusion
rates of water and sucrose (Dw/Ds) that increased
in a 35 % when augmenting temperature from 30
to 50ºC.
