Abstract
A simple technique was developed to dissect Pennisetum americanum grains into their anatomical parts. The proportions of the component parts of grains of different sizes were determined. The embryo represented a larger proportion of the grain wt. than in other common cereal grains. Medium-size grains (2240-2920 µm) contained 75.1% endosperm, 17.4% embryo and 7.5% bran (pericarp + aleurone). The amount of bran varied with the grain size and type of pericarp. Large grains ( more than 2920 µm) had 7.17% bran while small grains ( less than 2240 µm) had 10.64%. Small grains with thick and thin pericarps had 12.3 and 9.3% bran, resp. The whole grain and all fractions were analysed for protein, fat and ash with the following results: whole grain, 13.27, 6.26, 1.68%; endosperm 10.88, 0.53, 0.32%; embryo 24.52, 32.18, 7.18%; bran 17.07, 50.4, 3.20%, resp. The amino acid compositions varied among the different anatomical parts of the grain. The endosperm was lower in lysine, arginine and glycine and higher in glutamic acid and leucine than the whole grain
