This implies
that in this set of experiments oil reduction (dry base) in
vacuum fried slices would be mainly due to the reduction
in moisture loss during the process (for the same frying
time) and therefore the water vapor replacement mechanism
claimed for atmospheric frying would also apply to
vacuum frying. However, this should not be an exclusive
factor since compared to atmospheric frying most data
points are below the trend line, denoting lower oil contents,
implying that oil uptake is additionally impaired.
