Abstract:

This study aimed to analyze the relationships among the flavor compound 1-octen-3-ol in chicken breast meat, fatty acids, and lipid peroxidation markers, including superoxide dismutase (SOD) and malondialdehyde (MDA). In this experiment, the pectoral muscles of 15 42-day-old white feathered broiler chickens available for purchase in supermarkets was utilized. The volatile components of the chicken meat were analyzed via gas chromatography-mass spectrometry, the fatty acid composition was analyzed through liquid chromatography-mass spectrometry/mass spectrometry, and the levels of SOD and MDA in the samples were determined using the reagent kit. The results indicated a significant positive correlation between the chicken flavor compound 1-octen-3-ol and docosaenoic acid (cis-13) (C22:1) (P < 0.05). Additionally, C22:1 exhibited significant positive correlations with 6 unsaturated fatty acids (P < 0.05), including eicosaenoic acid (cis-11) (C20:1), eicosadienoic acid (cis-11, 14) (C20:2), eicosatrienoic acid (cis-11, 14, 17) (C20:3 (n-3)), docosadienoic acid (cis-13, 16) (C22:2), neuraminic acid (C24:1), and HOMO-γ-linolenic acid (C20:3 (n-6)). In the group with high 1-octen-3-ol content, significant differences (P < 0.05) were observed in the levels of 4 fatty acids: octanoic acid (C8:0), dodecanoic acid (C12:0), heptadecanoic acid (C17:0), and γ-linolenic acid (C18:3(n-6)). And no significant correlation was observed between 1-octen-3-ol and the oxidative indicators SOD and MDA. However, SOD showed a significant positive correlation with the unsaturated fatty acids EPA (C20:5) and C20:3 (n-3) (P < 0.05). MDA demonstrated a significant negative correlation with octanoic acid (C8:0) (P < 0.05) and significant positive correlations with the unsaturated fatty acids C22:1 and C24:1 (P < 0.05). In summary, the chicken flavor compound 1-octen-3-ol arises from the oxidation of linolenic acid. Lipid peroxidation in chicken breast muscle tissue generates more unsaturated fatty acids, but the extent of lipid peroxidation does not influence the formation of 1-octen-3-ol.

Key words: chicken flavor, 1-octen-3-ol, lipid pre-oxidation, linolenic acid
