title: [Study on quality of five hybrid corn kernels by FTIR spectroscopy].
abstract: The aim of this work was to study the feasibility of evaluating quality of corn kernels using Fourier transform infrared (FTIR) spectroscopy. The spectra of five kinds of hybrid corn kernels were obtained by infrared spectrometer rapidly. The infrared spectrum between 1 776 and 952 cm(-1) was composed of absorption bands of protein, starch and lipid mainly. The absorption band of starch was strong, and the band of protein was weak. The characteristic bands of starch, protein and lipid were highly overlapped, and main information was concealed. Curve-fitting the spectrum between 1 776 and 952 cm(-1), significant information was presented. The percentage of band area at 1 051 and 1 548 cm(-1) in total band area has a linear relationship with the concentration of starch and protein. The results showed that Fourier transform infrared spectroscopy combined with curve-fitting could be used to analyse the concentration of starch and protein in corn kernel, and provides a rapid and convenient method to study hybrid corn.
