Analysis on the Correlation between the Flavor Substance 1-octen-3-ol Content and Lipid Preoxidation of Chicken
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 dis-mutase(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 spectrome-try,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 re-agent kit.The results indicated a significant positive correlation between the chicken flavor com-pound 1-octen-3-ol and docosaenoic acid(cis-13)(C22:1)(P＜0.05).Additionally,C22:1 ex-hibited significant positive correlations with 6 unsaturated fatty acids(P＜0.05),including eico-saenoic 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,signifi-cant differences(P＜0.05)were observed in the levels of 4 fatty acids:octanoic acid(C8:0),do-decanoic 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 gen-erates more unsaturated fatty acids,but the extent of lipid peroxidation does not influence the formation of 1-octen-3-ol.
