| 摘 要： | 试验采用顶空固相微萃取和气相色谱-质谱联用法分析辐照猪肉中的挥发性成分.结果表明猪肉经辐照处理后挥发性成分的种类和峰面积都较未辐照的多,产生了较多的C5~C9醇和醛类,它们是不饱和脂肪酸的氧化产物;另外,也产生了阈值较低的二甲基硫、二甲基二硫等含硫化合物,经试验推测它们可能是含硫氨基酸辐照降解后的产物,并对猪肉辐照异味起主要贡献作用.

| Abstract: | Volatile compounds in irradiated pork were detected by headspace solid phase microextraction(HS-SPME) coupled with gas chromatography-mass spectrometry(GC-MS) in this study.The results showed that the types and peak area of volatiles in irradiated pork were more than those in nonirradiated pork.More alcohols and aldehydes with C5-C9 were detected in the pork after irradiation treatment,these compounds originated from the polyunsaturated fatty acids oxidation.In addition,sulfur compounds with low threshold v... |
