Apart from the influence of the cooking conditions on the generation
of volatile compounds, their stability after cooking was also
evaluated (Fig. 2). As can be observed, the total content of volatile
compounds significantly decreased from ST0 (252 AU 107) to
ST1 (95 AU 107), due to the diminishing of aliphatic hydrocarbons,
while the rest of chemical families kept their values. From
ST1 to ST2 the values of total volatile compounds went on decreasing
(95 and 49 AU 107, respectively) because of most chemical
families experimented a significant decrease, however, the levels
of polycyclic hydrocarbons maintained throughout this time.
