Oil uptake during frying mostly depends on the initial moisture content (Gamble and Rice, 1988;
Moreira et. al., 1997; Esturk et. al., 2000; Song et. al., 2007). During frying, oil fills the voids created in the product by rapid loss of water vapor. More rapid loss means more oil uptake.
Notably, oil uptake results followed the same trend as water holding capacity (Figure 2.6). There
were no significant differences (p > 0.05) observed in oil uptake with the increase in levels of
soy for samples with and without sodium bicarbonate.
Oil uptake decreased with increased monoglycerides (Figure 2.7). A higher level of
monoglycerides reduced shear or SME, causing less starch degradation and thereby less oil
16 uptake; however, oil uptake data did not differ significantly (P >0.05) for the samples with
sodium bicarbonate.
