Title: Replacement of wheat flour by sweet potato flour in bread making

Abstract

Wheat flour, a major ingredient for baking is mainly imported to Nigeria and many countries. Recent global economic crisis, foreign exchange fluctuation and challenges of importation has driven up the cost of wheat flour and subjected its availability to sporadic scarcities. This calls for use of alternatives in form of partial and total replacement of flour in bread production. This study was conducted to evaluate the replacement of wheat flour by sweet potato flour in bread making. Bread samples were developed using sweet potato flour to replace wheat flour at 0%, 25%, 50% and 100%. Samples were assayed for proximate and mineral composition. The control (100% wheat) had 23.50% moisture, 12.17% protein, 0.92% crude fibre, 2.33% crude ash, 3.00% fat, and 58.08% carbohydrate. The composite bread samples moisture, protein, crude fiber, ash, fat, and carbohydrate ranged as follows:24.17-30.83%, 0.6-9.19%, 0.83-1.11%, 1.40-2.40%, 1.00-5.00%, and 58.44-60.00%, respectively. The mineral content of composite bread samples ranged from 102-225mg, 305-688mg, 3.99-4.70mg, 178-196mg, 0.08-0.19mg, and 1.01-2.22mg for Potassium, Sodium, Iron, Phosphorus, Copper, and Zinc respectively. Mineral content was highest in 100% sweet potato flour. The nutritional profile of the samples however decreased with increasing percentage of sweet potato flour. However, 100% sweet potato bread was comparable to 100% wheat bread.
