This work consisted of two complementary sets of experiments in which breads differing in their recipe and/or process were characterised according to their odorant perception, volatile compound composition and physical properties. The results revealed that commercial partially baked and/or partially baked frozen breads were characterised by a different odour compared to commercial conventional, fully baked frozen and frozen dough breads, which were perceived similarly. These differences were explained by their variable aromatic composition. By analysing breads based on the same recipe but from different processes, it was demonstrated that adding a freezing stage before dough proofing or at the end of the conventional process, as well as after partial baking, did not influence bread aroma. Likewise, partial baking had no effect on bread odour and aromatic Profile. Thus, the aromatic differences between commercial conventional, fully baked frozen and frozen dough breads on the one hand, and commercial partially baked breads on the other hand, were due to their different formulations. Concerning bread physical properties, the recipe also influenced bread crust/crumb ratio and density. Moreover, adding a partial baking stage to the process led to breads with a more compact crumb.
