摘要: 利用动态顶空制样-热脱附-气相色谱-嗅闻-质谱联用技术,结合气味活度值(odor activity value,OAV)以及感官评价,对不同贮藏时间(0、7、14、21、35、49、77 d)的风干肠挥发性风味物质进行检测,分析贮藏过程中各类挥发性物质变化情况,并对造成异味的主要物质进行鉴别。结果表明:不同贮藏时间的样品中,分别检出挥发性风味物质59、56、63、58、73、68、71 种,主要为酯类物质;随着贮藏时间的延长,风干肠样品色泽变黑,失去光泽,异味逐渐增加,可接受度降低,其中有21、21、17 种风味活性物质分别与感官评价中色泽、风味、可接受度评分显著相关;经过OAV分析以及气相色谱-嗅闻鉴定,辛酸乙酯、1-辛烯-3-醇、正己醛、庚醛、正辛醛、壬醛、反,反-2,4-癸二烯醛可能是造成风干肠异味的主要物质。

Abstract: The volatile flavour compounds of air-dried sausages stored for different times (0, 7, 14, 21, 35, 49 or 77 days) were investigated and analyzed by dynamic headspace sampling combined with gas chromatography-olfactometry-mass spectrometry (DHS-GC-O-MS). Odor activity value (OAV) and sensory evaluation results were used to analyze the changes in volatile flavour compounds and the source of off-flavour. The results showed that a total of 59, 56, 63, 58, 73, 68 and 71 volatile flavour compounds, mainly esters, were detected in the samples stored for different times. With the increase of storage time, the color of the samples became darker and less glossy, the off-flavour intensity increased, and the acceptability decreased. A total of 21, 21, and 17 flavor active substances were significantly correlated with the color, flavor, and acceptability scores in sensory evaluation, respectively. By OAV analysis and GC-O identification, ethyl octanoate, oct-1-en-3-ol, n-hexanal, heptanal, n-octanal, nonanal and trans,trans-2,4-decadienal may be the main source of sausage off-flavour.

Key words: sausage, dynamic headspace sampling-gas chromatography-olfactometry-mass spectrometry, volatile flavour compounds, odour activity value
