Effect of Blending on Selected Sweet Potato Flour with Wheat
Flour on Nutritional, Anti-Nutritional and Sensory Qualities
of Bread
By Endrias Dako, Negussie Retta & Gulelat Desse
Abstract- This study was conducted to determine the possibility of blending selected sweet
potato flour to wheat flour to produce breads and to evaluate nutritional, anti-nutritional factors,
quality and sensory attributes of breads. Because of its potential source of nutrients compared to
yellow and white sweet potato varieties, orange sweet potato cultivar was selected for bread
making and six blending ratios of its flour with wheat flour (0:100, 5:95, 10:90, 15:85, 20:80 and
25:75) were designed. Functional properties of composite flour such as wet gluten and water
absorption capacity was decreased and, increased respectively as blending ratio of sweet potato
flour increases. Quality parameters of breads such as loaf size (volume, specific volume and
height) were significantly decreased but loaf weight was increased as blending ratio of sweet
potato flour increases.
Keywords: sweet potato, variety, proximate, mineral, anti-nutritional factors, breads, blending ratio,
