Fig. 2, a frying temperature of 110 °C produced the highest degree of expansion. Since there was no significant difference in the degree of expansion between 110 and 120 °C, higher frying temperature would not be necessary for increasing the expansion or the crispness of the product. At the same time, lower frying temperature would also reduce the energy cost of the frying process, as well as minimizing nutritional loss from higher temperature treatment.
