Effect of extruded finger millet (Eleusine coracanL.) on textural properties and sensory acceptability of composite bread

Abstract

Inclusion of native millet flour in refined wheat flour negatively affects the technological,textural and sensory propertiesofcompositebreads.Thepresentstudyexploresthepotentialofextruded finger millet flour inimprovingthequalityofcompositebread.Compositedoughswithextruded finger millet were significantly (p < 0.05) less firm and more extensible than their counterparts with unextruded flour. Breads elaborated from extruded finger millet (BEF) had better technological properties (higher specific volume and loaf height),good texture (low hardness,high resilience,low chewiness) than breads elaborated from unextruded finger millet (BUF) .Furthermore,phenolic content and antioxidant activity of BEF was significantly improved (p < 0.05) incomparison with the BUF and control bread. Sensory panel showed high preference for brown colour of composite breads (BUF and BEF) over control bread. Sensory scores of BEF were significantly (p < 0.05) higher than BUF, accounting for an overall high acceptability (8.5) of BEF20 (20g/100g substitution level) at par with control bread. Results strongly suggest that use extruded finger millet(20g/100g) is an effective way of enhancing phenolics, antioxidant activity, texture and sensory quality of composite bread.
