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（δasNH3+-谷氨酸钠）、谷氨酸钠分子COO-官能团不对称伸缩振动模式（νasCOO--谷氨酸钠）、谷氨酸钠分子NH3+官能团对称弯曲振动模式（δ■）、谷氨酸钠分子CH2官能团弯曲振动模式（δ■）和谷氨酸钠分子COO-官能团对称伸缩振动模式（ν■）。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 NH3+ functional group asymmetric bending vibration mode of (δ■), glutamate sodium molecular COO- functional group asymmetric stretching vibration mode (ν■), glutamate sodium molecular NH3+ functional group symmetric bending vibration mode (δ■), glutamate sodium molecular CH2 functional group bending vibration mode (δ■) and glutamate sodium molecular COO- functional group symmetric stretching vibration mode (ν■). 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.
