Abstract

In this study, a numerical model was developed to simulate frying of potato strips and estimate acrylamide levels In French fries. Heat and mass transfer parameters determined during frying of potato strips and the formation and degradation kinetic parameters of acrylamide obtained with a sugar-asparagine model system were incorporated within the model. The effect of reducing sugar content (0.3 to 2.15 g/100 g dry matter), strip thickness (8.5 x 8.5 mm and 10 x 10 mm), and frying time (3,4, 5, and 6 min) and temperature (150, 170, and 190 degrees C) on resultant acrylamide level in French fries was Investigated both numerically and experimentally. The model appeared to closely estimate the acrylamide contents, and thereby way potentially save considerable time, money, and effort during the stages of process design and optimization.
