摘　　要：采用中红外(MIR)光谱技术(包括:一维MIR光谱、二阶导数MIR光谱、四阶导数MIR光谱和退卷积MIR光谱)分别开展了鸡精结构的研究。实验发现:鸡精结构的主要红外吸收模式包括:谷氨酸钠分子NH3+官能团不对称弯曲振动模式(δasNH_(3)^(+)-谷氨酸钠)、谷氨酸钠分子COO-官能团不对称伸缩振动模式(ν_(asCOO)^(-)-谷氨酸钠)、谷氨酸钠分子NH_(3)^(+)官能团对称弯曲振动模式(δ_(sNH_(3)^(+)-谷氨酸钠))、谷氨酸钠分子CH_(2)官能团弯曲振动模式(δ_(CH_(2-谷氨酸钠)))和谷氨酸钠分子COO-官能团对称伸缩振动模式(ν_(sCOO-_(谷氨酸钠)))。研究发现,鸡精的主要成分是谷氨酸钠。为鸡精结构的鉴别研究,建立一个新的方法学,具有重要的应用研究价值。The structure of chicken semen was studied using mid infrared(MIR)spectroscopy techniques(including one-dimensional MIR spectroscopy,second-order derivative MIR spectroscopy,fourth-order derivative MIR spectroscopy,and deconvolution MIR spectroscopy).Experimental findings:The main infrared absorption modes of chicken sperm structure include sodium glutamate molecular NH_(3)^(+) functional group asymmetric bending vibration mode of(δ_(asNH_(3)^(+)-Glutamate Sodium)),glutamate sodium molecular COO-functional group asymmetric stretching vibration mode(ν_(asCOO-_(Glutamatc Sodium))),glutamate sodium molecular NH_(3)^(+) functional group symmetric bending vibration mode(δ_(sNH_(3)^(+)-Glutamate Sodium)),glutamate sodium molecular CH_(2) functional group bending vibration mode(δ_(CH_(2-Glutamate Sodium))) and glutamate sodium molecular COO-functional group symmetric stretching vibration mode(ν_(sCOO-_(Glutamate Sodium))).Research has found that the main component of chicken essence is glutamate sodium.The structure of chicken semen was identified and a new methodology was establish,which has important application research value.
