Cooking quality and nutritional properties of extruded maize pasta with orange-fleshed sweet potato

Vitamin A deficiency is prevalent in sub-Saharan Africa and is considered a serious problem of public health significance. The use of bio-fortified staple foods is an intervention strategy to address vitamin A deficiency and one example is orange-fleshed sweet potato (OFSP) cultivar with increased beta-carotene content. Replacing white-fleshed potato cultivars with orange-fleshed sweet potato can improve the vitamin A status of school-aged children. Taking this information into consideration, the diversification of diet through inclusion of orange-fleshed sweet potato could be a useful approach for alleviating vitamin A deficiency. This presents an opportunity whereby white maize flour can be composited with orange flesh sweet potato flour to produce gluten-free pasta with enhanced β-carotene content. This product will also be suitable for celiac patients and other consumers who want to abstain from gluten due to some health-related issues, and contribute to the RDA requirements for vitamin A for various groups. This study therefore investigates the effect of extrusion processing on cooking quality, β-carotene content and antioxidant properties of gluten free maize – orange-fleshed sweet potato pasta.
