Abstract

Three genotypes of pearl millet (Pennisetum glaucum L.) viz. PHB 2168, PHB 47 and PCB 164 were analyzed for their biochemical and processing characteristics. The moisture content ranged from 4.12-5.02 % with a mean of 4.49 %. Grain hardness varied from 2.18- 2.43 kg/grain being highest for PCB 164 (2.43 kg/grain) followed by PHB 2168 (2.40 kg/grain) and PHB 47 (2.18 kg/grain). PHB 2168 registered maximum protein (13.57%), minerals (2.06%), crude oil (6.06%), total sugars (2.32 %) and 1000 grain weight (11.39g) as compared to PHB 47 and PCB 164. The flour recovery at different moisture levels ranged from 44.8-52.7% amongst all the genotypes. PHB 2168 registered highest flour recovery than PHB 47 and PCB 164. PHB 2168 registered lowest pearling index value (32.9%) as compared to PHB 47 (49.9%) and PCB 164 (40.5 %). Optimum steaming time for conditioning grains was 9 minutes for all the genotypes. The effect of blanching on flour recovery revealed that as the bleaching time increased there is reduction of flour recovery from 51.95% (at 0.5 minutes) -28.8% (at 2.0 minutes) for PHB 2168. The reduction was more pronounced in PHB 2168 (44.5%) than in PCB 164 (20%) after 2 minutes of blanching. Pearling followed by soaking in HCl resulted into maximum grain recovery (average 87.3%) as compared to blanching for 1 or 2 minutes. The grain recovery was maximum in raw seeds soaked for 12 hours (93.3%) in comparison to pearling or blanching. The effect of blanching with citric acid (1.0 % and 2.0%) was more pronounced (85.5%, 84.8%)
