Abstract： This study aimed at developing acomprehensive quality evaluation model for six typical typesof salt-baked chicken in Guangdong.A total of11keyflavor compounds were identified byheadspace solid phase microextraction-gas chromatography-masspectrometry based on odor activity values （OAVs）.These flavor compounds and 12 physicochemical indicators suchas protein，water，andfatcontents were takenas independentvariables todevelopacomprehensivequality evaluation modelforsalt-baked chickenusing principalcomponent analysis （PCA）.Theresultsshowed thatthefirstfourPCs cumulatively explained 80.38% of the total variation，indicating that these PCs could well represent the original information ofthequalityindexesof salt-bakedchicken.Themodelresults were significantlycorrelated with thesensoryevaluation results.The gradingresultsof the proposed model forthe six types ofsalt-baked chicken were essentiallyconsistent with those of sensory evaluation.The modelcould providea more intuitiveand objective classification basis，which made the quality evaluation of salt-baked chicken more objective and accurate.
