Abstract


A total of 12 rice bran samples were collected from different sources and were analyzed for its proximate components, mineral contents and particle sizes. The quality of the rice bran available in Malaysia was found to be reasonably uniform. The dry matter, crude protein, crude fiber and ether extract contents were 92.58%, 12.11%, 7.01 and 16.38%, respectively. The average acid detergent fiber, neutral detergent fiber, lignin and ash contents were 6.56, 16.4 5.13 and 6.98%, respectively. The calcium and phosphonis levels were 0.05 and 1.45%; and Zn, Mn and Cu contents were 32.06 52.97 a.nd 3.58 mg per kg respectively. The whole rice bran was
fractionating to obtain the proportion of the particle size. The largest proportion of rice bran was within the particle size 0.15 mm (47.67%), followed by 0.215 mm (35.1I%), 0.15 mm (4.11%) and 1.0 mm (3.38%).
