The influence of the various factors involved in a culinary process
on the nutritive value of processed foods is of major concern
(Guidurus et al., 2010). In house holding conditions the controllable
variables are the cooking process, the oil variety and time/temperature
of processing. Several studies about the modifications of fat and
oil composition during heating and frying under very different conditions
have been carried out (Dobarganes et al., 2000). However, papers
on the changes in the foods are less abundant, and most of them
focused on fat uptake and water loss mechanisms during frying
(Debnath et al., 2003). Moreira et al. (1997) studied the effect of oil
temperature (130, 160 and 190 C) on the final oil content of tortilla
chips. Miranda et al. (2010) evaluated how the cooking method
(baking and deep frying in olive or sunflower oil) affects fatty acids
profiles of frozen breaded foods.
