Abstract

Fissuring associated with kernel expansion was evident in a moisture-adsorbingenvironment with RH; 88.72% with moisture content from 6% (d.b.) to 16.3% (d.b.). The averagekernel dimensions (length, width) were measured during the sorption test using a Cervitec GrainInspector, equipped with two digital cameras. The average kernel dimensions changed from 4.86mm to 5.50mm in length and from 2.75 mm to 2.86 mm in width. Dimension measurements wereconducted with three cultivars of brown rice kernels belonging to Japonica rice at a temperature of 15. The samples were exposed to both a moisture-adsorbing environment and a moisture-desorbingenvironment with relative humidities (RH) 23.4, 55.9, 70.98 and 88.72%. As an example of theresults, no kernel fissuring occurred in the moisture-desorbing environment with RH; 23.4% evenwhen the moisture content was reduced to as low as 6% (d.b.) from 23.3% (d.b.). The averagekernel dimensions changed from 5.13 mm to 4,84 mm in length and 2.9 mm to 2.73 mm in width.The results of the kernel dimensions measured with the Cervitec Grain Inspector changed in rice kernels as expected during moisture-adsorbing and moisture-desorbing tests. Kernels fissured whenexposed to a moisture-adsorbing environment for the conditions evaluated herein.
