<![CDATA[The objective of this study was to evaluate physical properties of rice bran forgery with corn cob addition. Corn cob mixed with rice bran by different levels 0%, 5%, 10%, 15%, and 20%. The experimental design was completely random design (CRD) with 5 treatments and 3 replications. The data were analyzed by ANOVA and followed by orthogonal contrast test if there were significant differences between the treatments. The results showed the addition of corn cob (0%, 5%, 10%, 15% and 20%) significantly (P<0.01) decreased the specific gravity (kg L-1) by 1.36, 1.32, 1.26, 1.20 and 1.16 (r = 93%), bulk density (g L-1) by 286.53, 283.02, 275.74, 268.35 and 263.86 (r = 98%), compact bulk density (g L-1) by 475.44, 463.69, 453.18, 443.14 and 433.53 (r = 99%) and angle of repose (˚) by 44.40, 43.91, 43.27, 43.15 and 42.70 (r = 93%) while the particle size (mm) increased by 1.22, 1.23, 1.23, 1.24 and 1.25 (r = 95.8%). Detection of rice bran forgery can be evaluated through physical test correlation and the highest correlation is found in the compact bulk density parameter.]]>
