Abstract

Powdered kunun-zaki (a beverage) was produced with 500 g of fermented sorghum residue and 200 g flavoured sweet potato paste. Blends were mixed with water, 10 g of granulated sugar and stuffed in a folded aluminum foil, steamed for 35 min. It was dried at 60 ± 1OC for 12 h, milled and sieved. The reconstitution time in warm water (45OC) and cold water (room temperature) were determined. The reconstituted sample was compared with freshly prepared kunun-zaki in terms of chemical and sensory properties. The pH values of the fresh kunun-zaki sample 2.03 was significantly different (p < 0.5) from that of the reconstituted kunun-zaki sample (3.61) indicating a higher hydrogen ion concentration in the freshly prepared kunun-zaki. There were no significant  differences (p > 0.05) between the samples in their protein, ash, fibre and carbohydrate contents. The result of the sensory evaluation revealed significant difference (p < 0.05) in terms of taste of the sample, but there were no significant differences (p > 0.05) in other parameters tested.
