Study was carried out to evaluate nutrient content of five rainfed lines of rice (IR47686-13, NERICA11, WAB569-35-1-1-1-HB, WAB781-140-1-1-HB, WAB897-B-B-B-B2) introduced in INERA GIMBI station. NERICA4 was used as local improved control. After moving away the husk, samples were separated in Husk and brown grains. These were separately analyzed at the Laboratory of biochemistry and food technology of CGEA/ CREN-K, in Kinshasa. Following parameters were evaluated on 100 g of each sample: moisture content (%), ash (%), fat (%), protein (%), dietary fibre (%) and lignin (%). Statistical analysis did not reveal significant difference in evaluated parameters of each part (grain and husk) of all varieties (Table 1), except protein content and lignin in husk (Table 3). Moisture, ash, protein, fibre, lignin and fat content were determined according to AOAC methods. It appears that the contents expressed as g/100 g (%) range as follows: moisture, 12.09-10.85; ash 1.51-1.01; protein, 7.57-5.70; fat, 2.73-0.93; fibre, 0.95-0. 74 and lignin, 2.34-1.82 for brown grain. For husk, following values (%) were obtained: moisture, 8.72-7.22; ash, 22.85- 15.83; protein, 1.77-1.45; fibre, 44.34-35.63; lignin, 59.00-45.58. These results can orient industry makers in the choice of rice varieties for milling to fight against malnutrition.
