We previously reported that nuclear magnetic resonance (NMR) micro imaging detected the hollows in cooked rice but required a specialist to operate equipment. Convenient detection of hollows is useful in the characterization of cooked rice. X‐ray imaging and light transmittance photography were studied as alternatives to NMR micro imaging. X‐ray imaging detected about 50% of all hollows. Light transmittance photography detected almost all hollows in cooked rice (Oryza sativa cv. Koshihikari) effectively and rapidly, relatively quantifying hollow sizes and numbers.
