where Aw andAo are constants; Ew andEo are constants
similar to activation energies for moisture outflow and
oil uptake andR (8.32 kJ/kg mol K) is the gas constant.
The values of Aw, Ao, Ew andEo are 60.96 s1
, 2.08 s1
,
2.55 104 kJ/kg mol and1.28 104 kJ/kg mol, respectively,
as inferredfrom the intercept andslopes of the
plot of ln Kw and ln Ko vs. T1 as per Eqns. (5) and
(6) (as shown in Fig. 3a). It is interesting to note from
Fig. 3b that increase in the coefficient for moisture
transfer (Kw) due to increased frying temperature
resultedin an increase in coefficient for oil transfer
(Ko) during frying.
