Abstract： The structure of sesame oil 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). The experiment found that the main infrared absorption modes of sesame oil structure include CH3 functional group asymmetric stretching vibration mode (ν■), CH2 functional group asymmetric stretching vibration mode (ν■), CH3 functional group symmetric stretching vibration mode (ν■), CH2 functional group symmetric stretching vibration mode (ν■), C=O functional group stretching vibration mode (ν■), protein structure amide I band mode (ν■), C=C functional group stretching vibration mode (ν■), protein structure amide II band mode (ν■), CH2 functional group bending vibration mode (δ■), CH3 functional group asymmetric bending vibration mode (δ■), CH3 functional group symmetric bending vibration mode (δ■), C-O functional group stretching vibration mode (ν■) and CH2 functional group rocking vibration mode (ρ■).Research has found that the main components of sesame oil are fats, proteins, and polysaccharides. This study establishes a methodology for the identification of the structure of sesame oil, which has important application research value.
