3.2. Moisture content
Moisture content is an important property of fried food product quality. During the frying process, the moisture evaporates at the product surface and leaves the product due to the different partial vapour pressure between the product and the frying oil (Moreina, 2003). Fig. 1 (a) shows that mainly the frying temperature but also the frying time decrease the moisture content of fried products significantly. Increased frying temperature leads to rapid decrease moisture content caused by higher water evaporation. Moreover, we can observe that the frying time is more effective at low frying temperature
