 ABSTRACT

In this study, the effects of microwaves on quality of fried potatoes (moisture content, oil content, color and hardness) were studied and the process was optimized by using Taguchi  Technique. Microwave power level (450W, 600W and 750W), frying time (2.0, 2.5, 3.0 minutes) and oil type (sunflower, corn and ground nut oil) were the parameters used in the study. Moisture content of  potatoes decreased whereas oil content, hardness and ΔE values of the potatoes increased with increasing  frying time and microwave power level. The potatoes with the highest oil content were  found to be  the ones that were fried in the hazelnut oil. The optimum condition was found as frying at 600W microwave power level, for 2.5 minutes in sunflower oil. The potatoes that were fried at the optimum condition were determined to have lower oil contents compared to the ones fried conventionally.

Key words: Microwave Frying; Optimization; Frying time; Different oil; Taguchi Technique
