Sažetak
Vitamin A deficiency is a public health problem in Nigeria, hitting the people in the savannah zones the hardest. This has accounted for child mortality and blindness. Therefore, there is a need to develop vitamin A rich food that is affordable and appealing to consumers. Orange-Fleshed Sweet Potato (OFSP) (Ipomoea batatas) is a variety of sweet potato now emerging as an important root crop with the possibility of tackling the problem of vitamin A deficiency. In this study, the physicochemical properties and sensory quality of Kunun-zaki, a non-alcoholic beverage sweetened with OFSP syrup, was compared to the same beverage sweetened with sugar and sugar syrup (100 mL/10 g of sweetener). The result of the physicochemical properties showed that the kunun-zaki samples were not significantly different in their pH and total titratable acidity; with values ranging from 3.93 to 4.0 and from 0.18 to 0.20 g/100 mL, respectively. The kunun-zaki samples were however significantly different in their obrix content. The OFSP sweetened sample recorded the highest obrix value of 15.20o, followed by the sugar sweetened kunun-zaki sample (13.30o) and the sugar syrup sweetened kunun-zaki (11.63o). The result of the sensory analysis showed that the sample sweetened with OFSP syrup had the best sensory attributes. The OFSP sweetened sample also had the best evaluated sensory attributes (colour, flavour, texture, and overall acceptability). The result of this study showed that Kunun-zaki sweetened with OFSP syrup was highly acceptable and could therefore serve as a dietary means of alleviating vitamin A deficiency, especially in the northern part of Nigeria where the local beverage is mostly consumed.
