Identification and quantification of volatile compounds responsible for bread’s aromatic profile
Bread’s texture and aroma are key factors influencing its acceptability by consumers.The main purpose of the present study was to characterize aroma compounds in three different French baguettes varying in their structural properties (density, hardness, size of alveoli and crumb’s heterogeneity). The volatile fraction of their crumb was isolated by Solvent Assisted Flavour Evaporation (SAFE) technique. Extracts were analysed by Gas Chromatography-Mass Spectrometry (GC-MS). Aroma-active compounds were determined by GC-Olfactometry (GC-O) and results were processed with detection frequency method. A total of 81 compounds (pyrazines, lactones, furans, ketones, pyrroles, aldehydes, alcohols, ac…
Gaining deeper insight into aroma perception: An integrative study of the oral processing of breads with different structures
WOS:000394071900015; International audience; The objective of this study was to investigate for the first time the influence of bread structure, volatile compounds, and oral processing on aroma perception. 3 types of French baguette were created using the same raw ingredients but different bread-making processes; they consequently varied in their crumb and crust structures. We characterized the initial volatile profiles of two bread structural subtypes-namely bread crumb and bread crumb with crust-using proton transfer reaction-mass spectrometry (PTR-MS) headspace analysis. Three types of bread were characterized by thirty-nine ion fragments from m/z 45 to 139. We then conducted a study in …
