Acrylamide content increased significantly with frying time for all frying
temperatures. The rate of acrylamide formation increased with
temperature, and it was greatest (about 6.06 ppb/s on average) for
the potato chips fried at 180 °C. At 150 °C, the concentration of acrylamide
content did not change significantly during the first 180 s of
frying (around 37 ppb) and then increased steadily (at rate of 1.63
ppb/s in average) to a value of approximately 484 ppb after 360 s of
frying. The final moisture content for the chips were as follows:
1.8% 0.3% (wb) (150 °C); 0.98% 0.1% (wb) (165 °C);
0.45% 0.03% (180 °C). The chips were overfried by 120 s when
fried at 165 °C and by 60 s at 180 °C to illustrate the effect of frying
time/temperature on the acrylamide formation of potato chips
fried in the traditional fryer.
