Infrared Spectroscopy Analysis of Barley and Wheat Seeds
LIU Jie
Abstract：It is of great significance for seed production and food safety to study the main chemical components of barley and wheat seeds by infrared spectroscopy.Fourier transform infrared spectroscopy(FT-IR)showed that the original spectra of barley seeds were similar to those of wheat seeds,and the absorption peak intensity and shape of the second derivative spectra(SD-IR)were different in the range of 1 800～800 cm1,indicating that barley and wheat seeds were different in lipid,protein and carbohydrate substances.Two-dimensional correlation infrared spectroscopy(2D-IR)showed that the position and intensity of auto-peaks in the range of 1 160～800 cm-1 and 1 600～1 160 cm-1 were different between barley seeds and wheat seeds,which further indicated that there were differences in the composition of barley and wheat seeds.The results show that infrared spectroscopy can effectively study the main components of barley and wheat seeds.
