Abstract
Brown and milled rice kernels of two long grain indica varieties (IR 60, KDML 105) and two japonica varieties (Koshihikari, Nipponbare) were subjected to lateral contact-point compression under controlled atmospheric conditions of 20°C and 33.0-75.5% RH.
The results showed that the breaking load of long grain rice ranged from 51-128 N, and rupture occurred at a lateral deformation of 59-97μm. The modulus of elasticity varied from 3.3-8.6 GPa which was slightly higher than the value previously reported for longitudinal compression.
