Detection of internal hollows in cooked rice using a light transmittance method

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