EFFECT OF REPLACEMENT OF WHEAT FLOUR WITH FINGER MILLET FLOUR <i>(ELEUSINE CORCANA)</i> ON THE BATTER MICROSCOPY, RHEOLOGY AND QUALITY CHARACTERISTICS OF MUFFINS

Abstract

ABSTRACT Effect of replacement of wheat flour with 0, 20, 40, 60, 80 and 100% finger millet flour (FMF), 60% FMF, emulsifiers and hydrocolloids on the batter microscopy, rheology and quality characteristics of muffins were studied. The amylograph peak viscosity, breakdown and setback values decreased as the level of FMF increased. The muffin batter microscopy showed that addition of above 60% FMF in blend decreased the number of air cells, indicating poor air incorporation. With the increase in the FMF level from 0 to 100%, the muffin batter density, viscosity, volume and total score decreased, whereas crumb firmness increased. Adverse effect on the quality characteristics of cake was observed above 60% FMF. Use of a combination of polysorbate‐60 and hydroxypropylmethylcellulose significantly improved batter characteristics of muffins with 60% FMF, with respect to viscosity, overall quality of muffin with reference to volume, grain and texture. PRACTICAL APPLICATIONS Muffins are normally made with wheat flour, and it is a very popular snack item largely consumed by children. Incorporation of finger millet flour, which is a good source of minerals, increases the nutritive value of muffins and also it is a value addition to the finger millet. The finger millet muffins have a familiar taste as it is widely consumed. This paper discusses the effect of replacement finger millet flour in muffins and the improving effect brought about by the use of additives. This information would benefit the baking industry.
