The physical properties of African nutmeg (monodara myristica) seed at 7.56% moisture content (dry basis) were determined by employing standard methods as a prerequisite to obtaining relevant data for the design of foods, equipment, machines and systems for its processing. The major, intermediate and minor diameters of the seed ranged from 15.2-23.1 mm, 8.9-13.4 mm, and 6.5-10.9 mm respectively with 18.29, 11.07 and 9.02 as respective volume and true density were averaged as 0.89g. 0.91cm3 and 0.95 g/cm3 respectively, the bulk density was 0.13 g/cm3 resulting in a porosity of 0.86%. Against steel, wood and plastic as structural surface, the coefficients of friction were derived as 0.36, 0.45 and 0.36 respectively, while the angle of repose was found to be 21.100. Most of these physical properties had linear relationship and positive correlation with the seed weight, which co-efficient of friction on plywood was highest (0.47). The minor diameter, sphericity and true density decreased with increased seed weight.
