Brown rice grain was thoroughly washed in drinking water for 5 min and drained for an extra 5
min. The rice sample was divided into three portions then subjected to different water uptake
techniques for 30 hrs; soaking in water (So), soaking in water and water spraying (SS) and water
spraying (Sp). The chamber temperature was controlled at 30±0.5°C and 35±0.5°C. The rice
