The feasibility of partially replacing wheat flour with malted rice flour in bread making was evaluated in several formulations,aiming to find a formulation for the production of malted rice-wheat bread with better nutritional quality and consumer acceptance.The whole grains of a local rice variety(Oryza sativa L.subsp.indica var.Mottaikaruppan) were steeped in distilled water(12 h,30°C) and germinated for 3 days to obtain high content of soluble materials and amylase activity in bread making.The quality of bread was evaluated by considering the physical and sensorial parameters.When the wheat flour was substituted with malted rice flour,35% substitution level and the malted rice flour from 3 days of germination was the best according to the physical and sensory qualities of bread.The quality of bread was improved by the addition of 20 g of margarine,20 g of baking powder and 20 g of yeast in 1 kg of flour.Among different ratios of yeast and baking powder,2:1 was the best.Bread improver containing amylases and oxidizing agents at the concentration of 40 g/kg was selected as the best concentration.When comparing the final formulation made in the bakery with wheat bread,malted rice-wheat bread contains more soluble dietary fiber(0.62%),insoluble dietary fiber(3.95%),total dietary fiber(4.57%) and free amino acid content(0.64 g/kg) than those in wheat bread(0.5%,2.73%,3.23% and 0.36 g/kg,respectively). The feasibility of partially replacing wheat flour with malted rice flour in bread making was evaluated in several formulations, aiming to find a formulation for the production of malted rice-wheat bread with better nutritional quality and consumer acceptance. The whole grains of a local rice variety (Oryza sativa L. subsp. Indica var. Mottaikaruppan) were steeped in distilled water (12 h, 30 ° C) and germinated for 3 days to obtain high content of soluble materials and amylase activity in bread making. The quality of the bread making. by considering the physical and sensorial parameters. WHERE the wheat flour was substituted with malted rice flour, 35% substitution level and the malted rice flour from 3 days of germination was the best according to the physical and sensory qualities of bread. the quality of bread was improved by the addition of 20 g of margarine, 20 g of baking powder and 20 g of yeast in 1 kg of flour. Amm different ratios of yeast and baking powder, 2: 1 was the best. er containing amylases and oxidizing agents at the concentration of 40 g / kg was selected as the best concentration. Comparison of the final formulation made in the bakery with wheat bread, malted rice-wheat bread containing more soluble dietary fiber (0.62%), insoluble dietary fiber (3.95%), total dietary fiber (4.57%) and free amino acid content (0.64 g / kg) than those in wheat bread (0.5%, 2.73%, 3.23% and 0.36 g / kg, respectively).
