Fig. 4. The oil uptake in a single fry (with a fat free dry matter content of 0.20 g/cm3 of total fry volume) plotted against the water evaporation rate obtained from Eq. (2). With
the experimental data (o), a dashed line representing the initial oil uptake oil0 (- -) and a line to guide the eye, indicating the chronological order of frying (?).
