Bulla is the water insoluble starchy product which is separated from Kocho during the decortications process of Enset. However, this extract lacks pro-vitamin A. This study enriched the Bulla with Orange-fleshed Sweet Potato (OFSP) a plant with high levels of β-carotene that can be useful for combating vitamin A deficiency. The porridge was made of composite flours of bulla blended with 30, 35, 40 and 45% OFSP flours were investigated for proximate composition, β-carotene, functional property and sensory acceptability of products using standard methods. The data were analyzed using SAS 1.9 Software. The composite flours percentage moisture, crude (fiber, protein, fat), ash, carbohydrate, gross energy, β-carotene, pH, bulk density and water absorption capacity were found to be in the range of 29.54 to 40.25, (1.66 to 2.05, 2.11 to 2.55, 0.55 to 0.71), 1.76 to 2.11, 53.86 to 63.31, 227.49 to 268.11 Kcal/100 g, 386.68 to 558.05 μg/100 g, 4.46 to 5.71, 0.58 to 0.80 and 1.70 to 4.87 ml/g, respectively. While, the composite flours porridge percentage moisture, crude fiber, ash, crude protein, crude fat, carbohydrate, gross energy, β-carotene, pH and viscosity content found to be in the range from 43.42 to 58.03, 1.32 to 1.79, 2.39 to 2.78, 2.01 to 2.31, 0.71 to 0.82, 35.21 to 48.63, 155 to 211.11 Kcal/100 g, 201.46 to 301.50 μg/100 g, 5.71 to 5.82 and 515 to 728 cps, respectively. The porridge OB4PM2 (45% OFSP and 55% Bulla) was most preferred due to its color, odor, flavor and overall acceptability with panelist scored value of 4.28, 4.33, 4.39 and 4.45, respectively. Moreover, OB4PM2 porridge was found to be good source of ash, energy and β-carotene content.

Vitamin A deficiency (VAD) and under nutrition are major public health concerns in developing countries. Diets with high vitamin A and animal protein can help reduce the problem of VAD and under nutrition respectively. In this study, composite flours were developed from orange fleshed sweet potato (OFSP), amaranth leaves and skimmed milk powders; 78:2:20, 72.5:2.5:25, 65:5:30 and 55:10:35. The physico-chemical characteristics of the composite flours were determined using standard methods while sensory acceptability of porridges was rated on a nine-point hedonic scale using a trained panel. Results indicated a significant (p < 0.05) increase in protein (12.1 to 19.9%), iron (4.8 to 97.4 mg/100 g) and calcium (45.5 to 670.2 mg/100 g) contents of the OFSP-based composite flours. The vitamin A content of composite flours contributed from 32% to 442% of the recommended dietary allowance of children aged 6–59 months. The composite flours showed a significant (p < 0.05) decrease in solubility, swelling power and scores of porridge attributes with increase in substitution levels of skimmed milk and amaranth leaf powder. The study findings indicate that the OFSP-based composite flours have the potential to make a significant contribution to the improvement in the nutrition status of children aged 6–59 months in developing countries.

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.

Vitamin A deficiency (VAD) is a public health problem in Ghana. Research on the orange flesh sweet potato root has been given prominence because of its high β - carotene content as a means to enhance the nutritive value and vitamin A content of the traditional diets of Ghanaian children as a long -term intervention towards combating VAD. Two Ghanaian cereal -legume weaning foods: roasted maize- soy blend and fermented maize -soy blend were added to Orange Flesh Sweet potato (O FS) flour from the variety, Beauregard, to develop four weaning food formulations . To each product formulation preparation, 25% and 50% OFS flour was added to the basic cereal - legume meals , and mixed thoroughly. The four weaning formulations were evaluated for chemical composition, sensory characteristics and consumer acceptability. All samples had a range of protein (12.1% - 15%), fat (4.8% - 6.4%), carbohydrate (71.1% – 75.1%), energy (380 - 390 kcal/100g) and minerals (calcium, iron and phosphorus) to ensure good nutrient density, while the moisture content was low (5.3% - 6.1%) for storage stability. The contribution of β -carotene ( 55.18 –115.55 ug/g) by the OFS in the formulations further enhanced the nutritive value of all the blends and is enough to meet the daily β -carotene needs of the children ( 1-6 yrs of 400 -450ug/100g). A higher level of β -carotene was seen in the roasted maize meal weaning foods which make s them a better potential blend for combating VAD. Also, sensory evaluation of the products indicated the highest consumer acceptability score (87%) for the roasted maize meal porridge formulation containing 25% OFS . It is, therefore , concluded that OFS flour has the potential to be used at 25% replacement level in the soy- fortified roasted maize meal formulation, and OFS is a useful ingredient with the potential to improve the β -carotene or vitamin A content of such formulations . This will help alleviate vitamin A deficiency of children in Ghana and other countries with similar problems . It is , therefore, recommended that the orange flesh sweet potato flour be used by mothers as an entry point for enhancing the traditional weaning food preparations .

Roots of orange-fleshed sweet potato varieties currently available in Nigeria contain high quantities of β-carotene or pro-vitamin A but have high moisture content. These varieties have been found to be a cheap and crucially important remedy for vitamin A deficiency. The cream or white-fleshed varieties, on the other hand, have a sweet taste with high dry matter content, giving a dry texture, a quality trait preferred in Nigeria. Development of sweet potato genotypes that can combine these two important quality traits is the objective of this breeding work. A diallel experiment using six parental sweet potato genotypes crossed in all possible combinations were carried out and thirty progenies were evaluated for beta carotene (β-carotene) and dry matter content in Landmark University, Omu Aran, Kwara State, Nigeria. The 30 F1 progenies along with their parental lines were planted in the same field trial. The trial was laid out in 6 x 6 triple lattice in two replications. Highly significant (P≤ 0.01) differences were observed among the genotypes for the traits. The average β-carotene content among the progenies was 2.86 (mg/100g.f.w) while the dry matter cttgontent had a mean value of 31.89%. The cross progenies 199024.2 x Excel had the highest beta carotene (14.37mg/100g.f.w) content with the highest dry matter content (40.10%) and are therefore recommended for further evaluation.

Provitamin A and pre-formed vitamin A compounds are essential micronutrients for humans. However, vitamin A deficiency (VAD) affects the health status of nearly 50% of populations in Southeast Asia and sub-Saharan Africa and is especially pronounced in preschool children and pregnant women. The objective of this research was to determine an acceptable flavor/ingredient combination to produce a palatable food product that incorporates sweet potatoes, peanut paste, and chickpeas. We sought to determine the acceptability of the three product formulations and to determine the influence of demographic data on ratings for the sensory attributes of each sample. To address VAD issues, three formulations of a product incorporating sweet potato puree (to increase β-carotene content), pure peanut butter (to provide fat for β-carotene absorption), and chickpeas (to provide a complete protein source), were developed: (1) an unflavored control, and two formulations with added natural seasonings: (2) curry-flavored, and (3) pumpkin spice-flavored. Sensory analysis of the three products showed that the curry-flavored product received the highest acceptability in terms of overall liking, flavor, texture, and appearance (p < 0.001). Since the demographic effect was not statistically significant (p > 0.05), it is highly likely that the curry-flavored product can be implemented in other countries or areas with high acceptability.
