The application of HPT processing caused statistical significant differences (p < 0.05) in the concentration of numerous volatile compounds with respect to their corresponding initial values. In fact, 31 out of 50 volatile compounds suffered significant variations after the application of HPT technology. The application of any HPT treatment caused significant reductions in the AAU of aliphatic hydrocarbons while, in the rest of chemical groups, the variations observed after HPT processing were increased with respect to the control values. The most remarkable augmentations in AAU volatiles were detected in furan and pyran, alcohol, and aldehyde groups, these increases being even higher than 100-fold (300 and 600 MPa combined with 80 °C), 60-fold (300 MPa combined with 50 and 80 °C), and 30-fold (300 MPa combined with 80 °C) over their respective control values (Table 1). It is important to highlight that these changes were dependent on the combination of pressure intensity and temperature assayed.
