通过现有检测技术结合国家相关标准,分析6种高盐剁辣椒坯的理化和气味滋味等品质指标。结果表明:样品中氯化钠质量分数16%~29%,其脆度和亚硝酸盐的差异可能与样品原料产地和保存时间有关。采用顶空固相微萃取技术与气相色谱-质谱联用(HS-SPME-GC-MS)并结合电子鼻进行气味分析表明,6种高盐辣椒坯的主要挥发性成分数量均在20种以上,以酯类和醇类数量居多,初步判定酯类和醇类物质是高盐辣椒坯挥发性成分的主要组分。利用电子舌比较其差异,得出高盐辣椒坯的风味主要表现在涩味、苦味、鲜味和丰富性等方面。

Through the existing testing technology together with national standards, the quality indicators for physical and chemical properties and odor of 6 high-salt chilies were analyzed. The results showed that the content of sodium chloride in the sample ranges from 16%~29%, and most of the physical and chemical indicators were not significantly different. The difference for brittleness and nitrite might be related to the origin and storage time of the raw materials. The odor analysis by headspace solid phase microextraction coupled with gas chromatography-mass spectrometry (HS-SPME-GC-MS) and elec...
