Structured Questionnaire

Background: The Integrating Orange Project promotes production and consumption of orange-fleshed sweet potato (OFSP) to address vitamin A deficiency among rural populations of Zambia since 2011. Objective: This study assessed household production and consumption of OFSP and identified factors associated with consumption thereof in Integrating Orange Project areas in Chipata district, Zambia. Methods: Respondents of 295 randomly selected households were interviewed using a structured questionnaire during the sweet potato harvest season. Associations between OFSP consumption and household factors were assessed using χ2 tests. Results: Frequency of OFSP consumption was categorized as ≥4 days during the last 7 days (30.2%), 1 to 3 days during the last 7 days (49.5%), eats OFSP but not during the last 7 days (7.1%), and never (13.2%). In total, 60.3% of households planted OFSP, and 40.0% bought OFSP, mostly from farmers within the community. Orange-fleshed sweet potato consumption was associated with the presence of children aged less than 5 years in the household ( P = .018), production of OFSP ( P < .001), purchasing of OFSP ( P < .001), and respondent having knowledge on health benefits of OFSP ( P = .014). Age and sex of the household head and household size had no association with OFSP consumption ( P > .05). Conclusion: A high percentage of households consumed OFSP during the harvesting season in Integrating Orange Project areas. Programs promoting OFSP consumption should thus focus on OFSP production and sensitizing households on nutritional benefits of OFSP and target households with children aged less than 5 years as entry point.

Contingent Valuation Methods

This paper analyzes how a newly developed food product (potagurt) with nutritional and health benefits can be promoted in Ghana. We employ the hedonic modeling and contingent valuation methods to estimate monetary values attached to the product’s attributes using 400 consumers in the Ashanti, Eastern, and Greater Accra regions of Ghana. The findings reveal that consumers have positive perceptions on the health and nutritional benefits of the product. Buyers place a higher value on potagurt relative to normal yogurt. The high value attached to potagurt is mainly linked to the health, nutritional, food safety, and quality attributes of the product, as well as perception. Consumers’ socioeconomic factors such as income, educational, and awareness levels also play a significant role in explaining their choice of the product. The practical implication is that the development and promotion of potagurt could stimulate sustainable economic development through better consumer health and improvement in the livelihoods of many players in the sweet potato value chain, especially the producers of potagurt and sweet potato farmers. We conclude that the promotion of the innovative food product could contribute to sustainable production and consumption of sweet potatoes.

Production And Consumption

β-Carotene-rich orange sweet potato (OSP) has been shown to improve vitamin A status of infants and young children in controlled efficacy trials and in a small-scale effectiveness study with intensive exposure to project inputs. However, the potential of this important food crop to reduce the risk of vitamin A deficiency in deficient populations will depend on the ability to distribute OSP vines and promote its household production and consumption on a large scale. In rural Mozambique, we conducted a randomised, controlled effectiveness study of a large-scale intervention to promote household-level OSP production and consumption using integrated agricultural, demand creation/behaviour change and marketing components. The following two intervention models were compared: a low-intensity (1 year) and a high-intensity (nearly 3 years) training model. The primary nutrition outcomes were OSP and vitamin A intakes by children 6–35 months and 3–5·5 years of age, and women. The intervention resulted in significant net increases in OSP intakes (model 1: 46, 48 and 97 g/d) and vitamin A intakes (model 1: 263, 254 and 492 μg retinol activity equivalents/d) among the younger children, older children and women, respectively. OSP accounted for 47–60 % of all sweet potato consumed and, among reference children, provided 80 % of total vitamin A intakes. A similar magnitude of impact was observed for both models, suggesting that group-level trainings in nutrition and agriculture could be limited to the first project year without compromising impact. Introduction of OSP to rural, sweet potato-producing communities in Mozambique is an effective way to improve vitamin A intakes.

This study examined the role of social-cognitive factors in farmers’ decisions to cultivate orange-fleshed sweetpotato as a food-based approach to alleviating vitamin A deficiency among rural households in Uganda. Cross-sectional survey data collected from 341 randomly selected household level decision-makers drawn from two rural districts in Uganda were analysed using hierarchical regression. Perceived capability and perceived social approval significantly predicted household decisions to grow orange-fleshed sweet potato (p≤0.001). Overall, decision-makers’ subjective norms and control beliefs were found to be significant mediators (p≤0.01) of the orange-fleshed sweet potato acceptance process. These results point to a cardinal role for processes that create supportive social and cognitive environments in promoting the cultivation of bio-fortified technologies such as orange-fleshed sweet potato.Keywords: Orange-fleshed sweet potato, social approval, Uganda

Orange Fleshed Sweet Potato

Since the late 1990s, the International Potato Center has promoted orange-fleshed sweet potato (OFSP) cultivars in Mozambique as a healthy food, emphasizing its capacity to reduce the prevalence of vitamin A deficiency among mothers and young children. This article seeks to reveal why consumers in Maputo, the capital city of Mozambique, adopt or reject OFSP looking at the role of food systems and consumer characteristics in access and acceptance of healthy food and at the positioning OFSP on the market in terms of lifestyle and need satisfaction. The results of 255 street interviews confirm that OFSP is widely known. Information reaches people mainly via informal channels (relatives and retailers). Nonadoption is the result of the positioning of OFSP as food for young children and sick people. The OFSP appeals most to the hedonistic and conservative lifestyle segments. Adoption is associated with the perception of OFSP as a source of vitamins that builds up muscles and improves physical appearance and self-fulfillment. While women are typically responsible for domestic tasks, male adopters emphasize the role of OFSP in family health and well-being more than female adopters. This first attempt to understand the marketing of healthy food in Mozambique exposes many similarities between the urban consumers in Maputo and those in developed countries. The results indicate that future marketing should exploit informal channels such as vendors and emphasize its nutritious value for all consumers instead of focusing on mothers and young children.

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.

Background Protein-energy deficiency (PEM) is still a major health issue in developing countries, and it is the leading cause of disease and death in children under the age of 5 years. Methods 100:0:0; 90:5:5; 80:10:10; 70:15:15; 60:20:20; and 50:25:25 per cent wheat:haricot bean: orange-fleshed sweet potato (OFSP) flours were used to make composite cookies. Standard methods were used to evaluate the proximate structure, physical properties, and sensory assessment. A one-way analysis of variance (ANOVA) model was used to statistically evaluate the data using the statistical analysis system (SAS) software package, version 9.0 standard methods. Results The results showed that partially replacing wheat with haricot bean and OFSP increased the proximate composition significantly. When wheat was replaced with haricot bean and OFSP, the physical characteristics of the biscuits did not vary significantly from those of biscuits made entirely of wheat flour. Sensory acceptability (appearance, color, flavor, taste, and overall acceptability) was higher in the composite biscuits with up to 40% wheat substitution than in the 100% wheat flour biscuits. Conclusions Based on the findings of this report, using OFSP and a haricot bean to wheat flour blend in biscuit formulation appears to be promising in terms of nutritional quality, acceptability, and cost. It is proposed that these products be marketed to vitamin A deficiency (VAD) customers as a newly established product to help mitigate food insecurity.

Orange Fleshed Sweet Potato

Vitamin A deficiency (VAD) remains a public health problem in developing countries. Consumption of orange-fleshed sweet potato (OFSP) varieties has been proven to be a valuable strategy for VAD alleviation. In this work, OFSP flour was incorporated into wheat flour at 15, 25, 35, and 50% (w/w) and used to prepare baked products. The bioaccessibility of provitamin A carotenoids of OFSP baking products was performed according to an in vitro digestion model. The contribution of OFSP-wheat composite baking products to vitamin A requirements was evaluated. Relatively high amounts (98.70&plusmn;2.17-144.42&plusmn;1.31 &mu;g/g DM) of total carotenoids in OFSP flours was reported in Kakamega-7-Irene, Kabode, and Covington cultivars. The recovery of provitamin A carotenoid in baking products containing 15, 25, 35, and 50% OFSP flour was 1031.04&plusmn;6.36-3364.21&plusmn;10.22 &mu;g/100 g for cupcakes and 1009.19&plusmn;10.38-4640.72&plusmn;13.43 &mu;g/100 g for cookies, respectively. The in vitro bioaccessibility of provitamin A carotenoids of OFSP composite cupcake ranged from 12.53 to 27.21% while that of OFSP composite cookies was significantly different (p ˂ 0.05) and ranged from 15.99 to 27.84%. The results also showed that cupcake and cookies containing 35% and 50% OFSP flours could be used to fight vitamin A deficiency in C&ocirc;te d&rsquo;Ivoire as they were found to meet 50 and more than 100% (161% for 100 g portion) of the recommended dietary allowance (RDA) of vitamin A for children aged 3-10 years. Finally, our results may support adoption of OFSP varieties in order to decrease the risk of vitamin A deficiency in C&ocirc;te d&rsquo;Ivoire.
