The average length and width of 800 kernels was measured during the sorption test using a Cervitec Grain Inspector equipped with two digital cameras. Samples were exposed to both a moisture-adsorbing and desorbing environments at 15 °C with relative humidities of 23.4±0.53%, 55.9±0.27%, 70.98±0.28% and 88.72±0.28%. On image analysis, the kernels changed in size from 5.13 to 4.84 mm in length and 2.9 to 2.73 mm in width. Both length and width changed as expected during moisture-adsorbing and moisture-desorbing tests. Fissured kernel percent was related to changes in the average length of the kernels during the moisture-adsorbing tests. The average length and fissured kernel percent of rice kernels measured by image analysis may be considered as a reliable indicator of changes in their dimensions during quasi-static moisture sorption processes.Elsevier2008-07engjournal articleAMhttp://hdl.handle.net/2115/68594https://doi.org/10.1016/j.jcs.2007.08.0090733-5210AA10624471Journal of Cereal Science48198103https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/68594/1/11_JCS07-104.pdfapplication/pdf282.28 KB2008-07
