The tian jinxiaozhan rice molecular structure had been studied by middle infrared (MIR) spectroscopy. There were νOH-tianjinxiaozhan rice, ν■, ν■, νC=O-tianjinxiaozhan rice, νamide-Ⅰ-tianjinxiaozhan rice, νamide-Ⅱ-tianjinxiaozhan rice and νC-O-tianjinxiaozhan rice. Temperature-dependent middle infrared (TD-MIR) spectroscopy of tianjinxiaozhan rice were studied also. With the increase of the temperature (303 K ~ 393 K), the infrared absorption intensity and frequency of tianjinxiaozhan rice main functional groups changed obviously and thermal stability further reduced. The paper demonstrated the key roles of MIR spectroscopy and TD-MIR spectroscopy in the analysis of structural and thermo stability analysis of the important agricultural products (tianjinxiaozhan rice).
