Abstract
Flour of fenugreek supplemented at 5, 10, and 15% levels with wheat flour was assessed for the production of bread and biscuit to improve nutritional profile. Germinated fenugreek flour samples had 29.89% crude protein, 7.91% crude fat, 11.35% crude fiber and 2.94% ash on dry weight basis. The wet gluten, falling number, and water activity of wheat flour reduced on incorporation of germinated fenugreek flour while the foaming capacity, water and oil absorption increased for bread and biscuit blended wheat flours. The farinograph water absorption values were 66.3, 63.9 and 61.8%, while the dough stability values were 7.0, 9.0 and 10.5 min at 5, 10 and 15% supplementation levels, respectively. The dough development times were 4.5, 6.1, and 7.5 min and farinograph quality numbers were 76, 100 and 123 Brabender units, respectively. The microbiological analysis of value added products for coliforms, E.coli, and yeast was absent, and TPC and mould counts were lower than control. The nutritive values in terms of protein, fiber, ash as well as calcium, magnesium, iron and zinc content of bread and biscuit increased as a result of the supplementation of germinated fenugreek flour to wheat flour. The sensory evaluation of the bread samples made by supplementation at 5 and 10% and 5% levels for biscuit were rated acceptable.
