Kinetics of moisture loss and oil uptake during deep fat frying of
puri was studied for puri with and without GG (0.5% w/w). The puris
were fried for varying durations, 5 s:5 s; 5 s:10 s; 10 s:10 s;
10 s:15 s; 15 s:15 s and 15 s:20 s. The moisture and fat content in
these puri samples were determined as previously described. The
equations for moisture outflow as well as oil uptake can be written
by considering the first-order mass transfer kinetics (Krokida et al.,
2000a,b)
