QUALITY ATTRIBUTES OF PANCAKES FROM PEELED AND UNPEELED SWEETPOTATO FLOURS WITH CASSAVA STARCH

Abstract

This study evaluated some quality attributes of pancakes from peeled and unpeeled sweetpotato flours and cassava starch. Cassava starch was substituted up to 30% of the total composite flour. The proximate composition, colour, carotenoid and functional properties of the different flour blends were determined. The flour blends were processed into pancakes and the proximate composition and sensory acceptability of the pancakes were determined. Data obtained were subjected to analysis of variance. The result showed that they were significant differences (p<0.05) in the functional properties of the flour blends. Bulk density, Water absorption capacity, Oil absorption capacity, swelling capacity ranged from 0.70 to 0.78 g/ml, 1.87 to 2.30 g/ml, 1.02 to 1.40 g/ml and 5.18% to 6.66% respectively. There were significant differences (p<0.05) in the proximate composition of the pancake samples. The values ranged from 42.76 to 45.53%, 2.13 to 3.98%, 9.06 to 10.34%, 5.01 to 7.18%, 3.75 to 6.01% and 29.19 to 35.33% for moisture, ash, fat, protein, crude fibre and carbohydrate contents, respectively. Pancake produced from 100:0 peeled and unpeeled sweetpotato flour had the highest score for overall acceptability which can compare favorably, with pancakes from wheat flour which is the control sample. In conclusion, sweetpotato flour blended with cassava starch at different ratio gave good proximate and functional properties which resulted in pancakes of good quality attributes.
