Effect of replacement of wheat flour with 5, 10, 15 and 20% multigrain mix (MGM) prepared by combining soya bean, oats, fenugreek seeds, flaxseed and sesame seeds on rheological and bread-making characteristics of wheat flour was studied. Use of increasing amount of MGM from 0 to 20% increased farinograph water absorption, caused disruption of protein matrix, decreased volume and increased crumb firmness value showing adverse effect of MGM on the volume and texture of bread. Addition of combination of additives to wheat flour with 15% MGM brought about significant improvement in the dough strength and overall quality of the bread. The protein, fat and dietary fiber contents of bread with 15% MGM was 1.5, 5.0 and 2.5 times higher than the control. The results showed that bread with improved quality characteristics and perceptible taste of multigrains could be produced by adding 15% MGM and combination of additives. PRACTICAL APPLICATIONSMultigrain breads are breads made with multiple grains, legumes and seeds. These breads are more nutritious, richer in flavor and tastier than normal bread. This article discusses the effect of replacement of wheat flour with a mix consisting of soya bean, oats, fenugreek seeds, flaxseed and sesame seeds on the dough properties and the quality of bread. This paper also highlights the improvement brought about by the addition of combination of additives on the rheological and bread-making quality of wheat flour with 15% multigrain mix. This information will have a practical application in the production of 1 Corresponding acceptable quality multigrain bread having typical grainy taste and improved nutritional characteristics in large scale.

Wheat flour fractioned by sieving into four different particle size fractions namely finer fractions (<75 and 75-118 μm), coarser fractions (118-150 and >150 μm) were analyzed for their chemical, rheological, bread & parotta making characteristics. The finer fractions had lower ash, higher dry gluten, damaged starch and sodium dodecysulphate (SDS)-sedimentation value than the coarser fractions. The flour from finer fractions gave bread with best sensory and textural attributes. The parottas from finer fractions showed significantly higher sensory scores for colour, texture, layers, mouthfeel and overall quality score than the coarser fractions. In the micrograph of finer flour fractions, higher number of loosened single starch granules than the aggregates of starch and protein matrix were seen as compared to coarser fractions. These studies indicate that the flour from the finer fractions produce higher quality bread, parotta owing to the presence of higher damaged starch content, quantity and quality of protein in these fractions than coarser fractions.
