, when moisture content of these seeds increased between 1 and 1%. The kernel density of axseed remained relatively constant at approximately 1 kg/ 3between 8.2 and 1.6% moisture content. Deshpande et al. ( measured the kernel density of soybeanusing liquid displacement method. The grains were coated with very thin layer ofepoxy resin adhesive (Araldite) to avoid any absorption of water during the experimentas used earlier by Dutta et al. (1a). The adhesive was insoluble in water, resistant toheat, humidity, solvents, and acids. The increase in weight of the grain owing to adhesive coating was less than 1.5%, and there was no change in weight of the grain even if it was kept submerged in distilled water for 2 . The effect of moisture content on kernel densityof soybean grain showed linear decrease with moisture content. Tao et al. ( usedan indirect method to determine the volume of preweighed rice bran. They obtained thevolume of the rice bran samples from porosity determination. The true densities of branof long and medium rice were reported to be 1 kg/ 3, and 1 kg/m3, respectively. The densities of wheat and canola kernels have also been determined using liquid displace- ment method (Sokhansanj and Lang, . Kernel density values for different grains aresummarized in Table 2. 2.5 Porosity The porosity of grain is an important parameter that affects the kernel hardness, breakage susceptibility, milling, drying rate, and resistance to fungal development (Chang, . Porosity is property of grain that depends on its bulk and kernel densities. The grainporosity can be measured with the help of an air comparison pycnometer or by the mercurydisplacement method. The values of grain porosity of various grains, as measured withthe former method, tend to be 5% higher (Thompson and Issacs, .
