摘　　要：采用感官分析方法—时间-强度法(time intensity,TI)和定量描述分析法(quantitative descriptive analysis,QDA),结合HPLC,对8种不同产区的花椒油的麻感特征及麻味物质进行了测定。TI结果展示了花椒油的时间动态特性,ZAO1样品具备最高的麻感强度(intensity of maximum,I_(max))和曲线下面积(area under the curve,AUC)。I_(max)与AUC之间呈现出较好的正相关性。QDA结果揭示了不同产区花椒油的麻感属性差异,其中麻木感、振动感、垂涎感在ZAO1样品中表现突出,而在ZBO4样品中表现最弱;灼热感在ZAO2样品中表达最为强烈。HPLC测定结果显示,不同产区的花椒油的麻味物质组成及含量存在显著性差异。进一步偏最小二乘回归(partial least squares regression,PLSR)分析表明,羟基-α-山椒素(hydroxy-α-sanshool,HαSS)是影响麻木感、振动感和垂涎感的关键物质。此外,麻木感、振动感和垂涎感之间呈现出较好的正相关性。该结果初步揭示了花椒油中麻感特征差异及其与麻味物质的关联性,为我国花椒油的品质监控提供实验数据和理论基础。Eight pepper oil samples soured from different production areas were analyzed for their pungency characteristics and numbing substances by using sensory analysis methods[time intensity(TI)and quantitative descriptive analysis(QDA)],combined with HPLC.The TI results provided insights into the time-dynamic properties of the pepper oils,with the ZAO1 sample exhibiting the highest area under the curve(AUC)and intensity of maximum(I_(max)).Additionally,the I_(max) and AUC displayed a good positive correlation.QDA results revealed noticeable differences in the pungency sensation attributes of pepper oils among various production areas.Notably,the ZAO1 sample was characterized by pronounced“numbness”,“vibration”,and“salivation”sensations,while the ZBO4 sample showed the weakest intensity of these attributes,and the“burning”sensation was the strongest in the ZAO2 sample.The HPLC results indicated that there were significant differences in the content of sanshools in pepper oils from different production areas.Further partial least squares regression(PLSR)analysis identified hydroxy-α-sanshool(HαSS)as the key substance influencing the“numbness”,“vibration”,and“salivation”sensations.In addition,a positive correlation was observed among“numbness”,“vibration”,and“salivation”.These findings provided preliminary insights into the pungency characteristics of pepper oils and their correlation with numbing substances,thereby offering valuable experimental data and a theoretical basis for the quality monitoring of pepper oil in China.
