摘　　要：为分析一些爆珠香精调配过程中存在的香精嗅香好但感官品质差的原因,以咖啡特征爆珠香精为例,利用中心切割和静态顶空的方法考察了爆珠中2,3,5,6-四甲基吡嗪和糠硫醇的传递效率和挥发性,利用原位漫反射红外光谱技术深入剖析了糠硫醇在聚二醋酸纤维表面的吸附机制。结果表明:糠硫醇和聚二醋酸纤维的相互作用强于2,3,5,6-四甲基吡嗪;吸附在聚二醋酸纤维上的糠硫醇S—H键伸缩振动红外吸收峰向低波数位移,=C—H的平面外弯曲振动红外吸收峰向高波数位移。To understand possible reasons behind good flavor and poor sensory quality of some flavors released during breakable capsule usage,breakable capsules with coffee-like characteristic flavor were used as the study samples and the transfer efficiency and volatility of 2,3,5,6-tetramethylpyrazine and furfuryl mercaptan from the breakable capsules were investigated by central-cutting and static headspace analyses respectively.An in-situ diffuse reflectance infrared spectroscopy was adopted to analyze the adsorption of the characteristic aroma components from the breakable capsules on the surface of polydiacetate fibers.The results showed that:The interaction between furfuryl mercaptan and polydiacetate fibers was stronger than that between 2,3,5,6-tetramethylpyrazine and polydiacetate fibers.When furfuryl mercaptan was adsorbed by polydiacetate fiber,the S-H bond stretched vibration infrared absorption peak to lower wave numbers,and=C-H out-of-plane bent vibration infrared absorption peak was shifted to higher wave numbers.
