Objective In this study, orange-fleshed sweet potato (OFSP) puree was substituted with wheat flour (48:52%) in the production of spaghetti, herein denoted VitAspag and compared with three existing whole wheat brands (Local, Oba and Spaghetti). Methods Hundred untrained panel list evaluated the colour, taste, stickiness, firmness and overall acceptability using a 5-point hedonic scale. The proximate and β-carotene content of VitAspag was carried out using standard methods and compared with the most preferred existing brand, Spaghetti. Results The sensory scores for all spaghetti brands were above 3, an indication of good consumer acceptability. There was no significant (p>0.05) difference among vitAspag, Local, Oba and Spaghetti with respect to all sensory attributes considered. The moisture, ash and fibre content ranged from 8.90% - 9.50%, 1.15% - 1.20% and 0.42% - 0.62%, respectively. Spaghetti, had a significantly higher protein (2.02% vs. 0.05%; p<0.001) and carbohydrates (81.0% vs. 79.7%; p = 0.024) content compared with VitAspag. VitAspag, was also significantly (p<0.001) higher in β-carotene, almost 1.6 times higher than Spaghetti. A 125 g and 500 g of vitAspag per day will respectively meet 10% and 9.03% of the daily vitamin A requirement of children <5 years (300 µg RAE/day) and pregnant and lactating mothers (1,300 µg RAE/day). Conclusion Ranking VitAspag similar to the existing commercial brand is an indication that consumers will equally accept it. OFSP puree could be composited with wheat flour up to (48:52%) on as is basis to make spaghetti and will contribute to a significant amount of dietary intake of vitamin A.

Orange Fleshed Sweet Potato

Purpose: Vitamin A deficiency is among major health problems worldwide that leads to blindness, retarded growth and death, particularly in developing countries. In these countries, vitamin A deficiency largely affects pre-school children, pregnant and lactating mothers, and the rural poor. For instance, the predicted prevalence of vitamin A deficiency for 36 sub-Saharan African countries is 19.1 %. Methods: Different strategies, including vitamin A supplementation, food fortification and dietary diversification, have been used to combat this problem. However, these strategies are not sustainable due to their high costs. Results: Orange-fleshed sweet potato (Ipomoea batatas L. Lam) is a low priced crop, which is part of staple foods in most of sub-Saharan Africa that can be a year-round source of vitamin A. Most of the orange-fleshed sweet potato varieties contain 3000 - 16000 μg 100 g-1 of β-carotene and this contributes to 250 to 1300 μg 100 g-1 Retinol Activity Equivalents (RAE). Therefore, by using orange-fleshed sweet potato, it is possible to improve vitamin A status, increase the bio-availability of different micro-nutrients such as Fe, Zn, Ca and Mg, reduce vitamin A deficiency and hence reduce child mortality rates by 23 to 30 %. Conclusion: The article highlights the significance of vitamin A for human nutrition, the effect of vitamin A deficiency, the different prevention methods and the potential of orange- fleshed sweet potato as a food crop to prevent vitamin A deficiency.

Sensory quality and vitamin A retention in chin-chin stored using different packaging materials were evaluated. The Orange Fleshed Sweet Potato (OFSP) and Red Bambara Groundnut (RBG) flours were blended in ratio 50:50 for chin-chin production. Sensory quality, β-carotene and vitamin A contents of the chin-chin were analyzed using standard methods. Storage stability test of β-carotene and vitamin A retention were investigated using plastic bottles, high and low densities polyethylene packaging materials at ambient conditions (29.95±5.00°C, relative humidity 68.32±3.55%). The total vitamin A µgRAE retention in the chin-chin was estimated every week for four weeks and after twelve months. Moisture was least absorbed by chin-chin packaged in plastic bottles. The Vitamin A retentions were about 80 percent, 74 percent and 72 percent for plastic bottles, high density polyethylene and low density polyethylene, respectively after twelve months of storage. Texture, taste and overall acceptability were better retained when packaged in either plastic bottles or high density polyethylene. The chin-chin produced was able to store for up to twelve months when packaged in plastic bottles or high density polyethylene.

This study assessed the nutrient composition, physicochemical, functional and sensory properties of flour blends prepared from cooking banana, pigeon pea and orange fleshed sweet potato flour blends for use as complementary food. Fourteen blends were generated using the simplex centroid mixture design. All data obtained were subjected to analysis of variance and the mean values were separated using Duncan’s Multiple Range Test. The protein, crude fibre, crude fat, ash and carbohydrate of the blends were significantly (p≤0.05) different with values ranging from 10.60-21.65%, 0.36-1.24%, 1.2-1.43%, 0.77 – 2.25% and 65.86 -75.36%, respectively. There was no significant (p≤0.05) difference in the moisture content, total carotenoid content and pH value of the blends. The L* value (40.77 to 45.25) showed no significant (p≤0.05) difference while the redness (a*) and yellowness (b*) value were significantly (p≤0.05) different with values ranging from 2.32 – 4.59 and 11.88 – 15.88 respectively. There was a significant (p≤0.05) difference in the bulk density (0.73 – 0.78 g/ml), water absorption capacity (122.05-178.10%), swelling power (6.21 – 8.48%) and solubility (3.77-7.30%) values. Gruels obtained from the flour blends had sensory scores of above 6.00 (on a 9-point Hedonic scale), signifying high acceptability for all the sensory attributes evaluated.
