Abstract：The key volatile flavor compounds of Dezhou braised chicken were analyzed and identified by electronic nose and gas chromatography-mass spectrometry (GC-MS), and their relative odor activity values (ROAV) were calculated. Aromatic hydrocarbons and nitrogen-containing sulfur compounds were detected in Dezhou braised chicken by electronic nose; 54 volatile flavor compounds were detected by GC-MS, of which the key flavor compounds (ROAV ≥ 1) were nonanal (100.00), decanal (81.67), hexanal (38.94), octanal (19.29), heptanal (14.50), limonene (14.08), 1-octene-3-ol (11.50), 2-pentanyl furan (10.14), eucalyptol (9.71), estragole (5.69), eugenol (5.56), linalool (3.86), α-pinene (3.08), and anethole (2.01). The number of olefins was the largest among the classes of volatile flavor compounds identified, and aldehydes were the key flavor compounds. The key flavor of Dezhou braised chicken included meaty, five-spice and medicinal herbal aroma.
