Development of quick cooking multi-grain dalia utilizing sprouted grains.

Abstract

Multi-grain dalia (MGD) formulations were prepared utilizing sprouted wheat and mixer of other three grains (barley, sorghum and pearl millet) in the ratio of 100:0 (MGD-A), 75:25 (MGD-B), 50:50 (MGD-C), 25:75 (MGD-D) and 0:100 (MGD-E), respectively. The mixer of barley, sorghum and pearl millet was prepared using 50, 25, 25 parts of these grains, respectively. The recovery of grits/ dalia (particle size 1.41 to 2mm) from sprouted wheat and barley was 74.56 and 69.77%, respectively while sorghum and pearl millet yield 47.94 and 49.39% (particle size 0.954 to 1.41mm), respectively. Sprouting brought a reduction of cooking time by about 50% as compared to un-sprouted studied grains. Cooking time for different MGD formulations ranged from 3.91 to 4.42min, which was slightly increased with increasing proportion of mixer of barley, sorghum and pearl millet (p > 0.05). Rehydration ratio of MGD samples varied from 3.12 to 3.45 with minimum in MGD-E sample. Though protein content was decreased with increasing proportion of mixer of three grains in MGD samples but in vitro protein digestibility (58.68 to 62.75%) was similar (p > 0.05). The mean overall sensory acceptability scores for MGD samples ranged from 7.50 to 8.49 with ≥8.0 in samples having up to 75% grits of mixer of three grains. In view of very good overall sensory acceptability, rich in crude fibre, calcium and iron content and low cooking time, 25:75 parts of sprouted wheat and mixer of studied three grains, respectively may be considered for preparation of acceptable quality quick cooking multi-grain dalia.
