Before testing, the GBR samples were cooked in the aluminum
cylindrical can using a rice to water ratio of about 1:1.5. The textural
properties of cooked GBR were measured by Texture Analyzer
(TA.XT Plus, Stable Micro Systems, Ltd. in Godalming, Surrey UK).
The cooked GBR samples comprising about 12 grains were placed
on a plate. The cylindrical probe, with a diameter of 50 mm,was used
for testing cooking characteristics such as hardness and stickiness.
The probe was compressed at a pretest speed of 1 mm/s and posttest
speed of 10 mm/s. The hardness value was defined as a maximum
compressive force at 85% strain of force deformation curve.
