shows oil uptake versus moisture
loss during vacuum and atmospheric frying of carrot slices. The
strong relationship between them suggests that the water vapour
replacement mechanism, which is said to occur during atmospheric
frying, would also take place during vacuum frying, as
determined by Mariscal and Bouchon (2008). Statistical analysis
showed that both the frying method and the thermal driving force
had a significant effect (p < 0.05) on oil uptake (g oil/g dry solids)
for the same dehydration level. In fact, vacuum fried carrot slices
absorbed 47% and 50.5% (d.b.) less oil than atmospheric fried ones
at bubbled-end point when using thermal driving forces of 60 C
and 80 C, respectively. When comparing vacuum fried carrot
crisps, those fried using a thermal driving force of 60 C absorbed
a significantly lower amount of oil compared to those fried using
a thermal driving force of 80 C. These results concur with those
