摘要： Paojiao, which is traditionally pickled Chinese chili peppers (Capsicum frutescens Linn.), possesses unique flavors. This study was conducted to investigate the flavor, mouthfeel, and consumer acceptability of Paojiao. The quality of six homemade and two industrial Paojiao samples were evaluated by integrating untargeted (to fingerprint volatile fraction) and targeted (to analyze free amino acids or FAAs, capsaicinoids, and texture) approaches. Furthermore, multivariate data analysis (MVDA) was applied to identify the quality characteristics that drive the consumer acceptability for Paojiao. As for the targeted quality, hardness (1.30-10.52 N) and capsaicin (2.22-3.84 mg/g) varied with different samples. The main taste-active FAAs in Paojiao were detected. A total of 127 volatiles were observed, and esters were the major components. Based on sensory analysis, the homemade samples received higher acceptability than the industrial samples. MVDA demonstrated that some key volatiles, taste-active FAAs, and chewiness were the discriminant quality attributes affecting consumer acceptability.
