Abstract: In order to study the correlation between the cracking of rice (Oryza sativa L.) kernels and themolecular structure of the amylopectin in them, we attempted optical sum frequency generation(SFG) spectroscopy in the C-H stretching vibration region for normal and cracked japonica nonglutinousrice kernels. The samples were Koshihikari and Nipponbare. In Nipponbare, the width ofthe SFG spectrum peak at 2915 cm^-1 of the cracked rice kernels was broader than that of the normalones, while for Koshihikari there was no clear difference. The width of the 2915 cm^-1 peak issuggested to originate from the variety of the higher-order structure of the saccharide chains inamylopectin. Although this is a tentative result, this method is shown to have a potential of servingfor preventing the cracking of the rice kernels.
