摘　　要：为探究电子束辐照对鸡胸肉异味产生的影响,对不同剂量辐照鸡胸肉中的挥发性化合物进行检测和分析。用固相微萃取-气相色谱-质谱联用法(solid phase microextraction-gas chromatography-mass spectrometry,SPME-GC-MS)对不同剂量辐照鸡胸肉中的挥发性化合物进行分析,对辐照鸡胸肉进行感官评价实验,结合挥发性化合物含量进行偏最小二乘回归分析(partial least squares regression,PLSR)。检测到了18种香气活力值(odor activity value,OAV)大于1的挥发性化合物,其中2 kGy剂量辐照对鸡胸肉中挥发性化合物影响最明显。确定了对鸡胸肉果香、霉香、油脂、鸡肉味、油漆味有重要贡献的特征化合物。感官评价得分结合挥发性化合物的OAV表明反-2-辛烯醛、1-辛烯-3-醇、壬醛、3-羟基-2-丁酮可能是辐照鸡胸肉产生辐照异味的特征化合物。实验结果为电子束辐照食品中异味的检测及掩盖提供理论依据,推动电子束辐照保鲜技术在其他食品中的应用。To investigate the effect of electron beam irradiation on the odor of chicken breast,volatile compounds in chicken breast at different doses of irradiation were detected and analyzed.The volatile compounds in the irradiated chicken breasts at different doses were analyzed by solid-phase microextraction-gas chromatography-mass spectrometry(SPME-GC-MS),and sensory evaluation was performed on the irradiated chicken breasts,combined with partial least squares regression analysis(PLSR)for the content of volatile compounds.Eighteen aroma compounds with odor activity value(OAV)greater than 1 were detected,with the most significant effect of 2 kGy dose irradiation on volatile compounds in chicken breast meat.Characteristic compounds that contributed significantly to the fruity,musty,greasy,chicken flavor,and paint flavor of chicken breast meat were identified.The sensory evaluation scores combined with the OAV values of the volatile compounds indicated that trans-2-octenal,1-octen-3-ol,nonanal,and 3-hydroxy-2-butanone may be the characteristic compounds for irradiated chicken breasts generating irradiated off-flavors.
