“…Standard, fluorescent lights illuminated the room for the visual tests. Results of this study were consistent with Kaspar et al (2013), where consumers did not detect significant differences between potato cultivars, and Tomlins et al (2007) where consumers in the lake zone of Tanzania rated OFSP as highly acceptable.…”

Orange flesh sweet potato (OFSP) is a globally important staple crop. Health benefits of OFSP are substantial, especially for nutrition-endangered populations. Compared to the Irish potato (IP), OFSP is a richer source of nutrients and fiber. In some parts of the world, OFSP is unfortunately regarded as a poor farmer's crop. This negative reputation has resulted in reduced acceptance of OFSP by populations that could benefit greatly from it. One purpose of this paper is to promote acceptance of OFSP by demonstrating sensory preference of OFSP compared to IP. The second purpose is to recognize a global effort to develop food products using OFSP. Consumer taste tests were conducted to compare OFSP and IP cooked and prepared using common methods of mashing and cubing. Published journal articles that reported development of foods with OFSP as a primary ingredient were identified. Recipe developers must have used a rigorous technique of sensory analysis to test products. Consumers did not show a significant preference for the taste or appearance of mashed or cubed OFSP compared to IP. Researchers from 9 different countries have developed food products that included OFSP in 22 different categories over a 26-year period. OFSP has been successfully utilized in the development of many well-liked food products. Continuous education and exposure of future generations of scientists and consumers to the benefits of OFSP will result in broad-based acceptance.

“…Earlier attempts to introduce orange-fleshed cultivars from Taiwan, Mainland China, and IITA failed because of their low dry matter content and squash-like flavour [27]. However, consumer acceptance has improved tremendously due to several research and promotions to address these weaknesses in countries such as Mozambique [28], Kenya [29], Ghana [30], and Tanzania [31]. Although consumers preferred orange-to white-fleshed cultivars, their low dry matter content was a limiting quality attribute [28].…”

Sweet potato has gained prominence due to its ability to adapt to wide production ecologies and yield response to minimal external inputs. Orange-fleshed cultivars in particular have immense potential to improve household income and nutrition in sub-Saharan Africa. However, the sweet potato value chain (SPVC) is not well-developed in many producing countries. The study was conducted in two regions to characterize the production operations as well as identify opportunities to propel the SPVC in Northern Ghana. Data were collected using mixed methods including structured questionnaires via face-to-face interviews. Analysis of strengths, weaknesses, opportunities, and threats (SWOT) was conducted at multistakeholder platforms with different actors. Gross margin profit and benefit-cost ratios were determined by using six cost variables. Overall, the industry was largely a fresh produce market, targeting food vendors, processors, and direct selling to wholesalers, retailers, and household consumers. The SWOT analysis revealed wide-ranging opportunities including favourable production ecologies, processing options, and insatiable local and international markets. The institutional actors need to network the primary actors to synergistically operate with a collective profit motive. The most prioritized production constraints such as access to seed, cost of chemical fertilizer, short shelf-life, field pests and diseases, and declining soil fertility should be addressed.

“…A combination of these two theories has been shown to improve the ability to explain nutrition behavior [12], [13], [14]. Most acceptability studies in developing countries are entirely qualitative and use for example focus group discussions and interview methods in study populations selected by convenience [15], [16], without verifying the associations between beliefs or attitudes and consumption in larger representative populations. As such, a lot more insight can be gained into possible ways to influence nutrition behavior.…”

Biofortified Cassava with Pro-Vitamin A Is Sensory and Culturally Acceptable for Consumption by Primary School Children in Kenya

et al. 2013

BackgroundBiofortification of cassava with pro-vitamin A can potentially reduce vitamin A deficiency in low-income countries. However, little is known about consumer acceptance of this deep yellow variety of cassava compared to the commonly available white varieties. We aimed to determine the sensory and cultural acceptability of the consumption of pro-vitamin A rich cassava in order to identify key factors predicting the intention to consume pro-vitamin A rich cassava by families with school-aged children in Eastern Kenya.MethodsSensory acceptability was measured by replicated discrimination tests and paired preference tests among 30 children (7–12 yr) and 30 caretakers (18–45 yr) in three primary schools. Cultural acceptability was assessed with a questionnaire based on the combined model of The Theory of Planned Behavior and The Health Belief Model in one primary school among 140 caretakers of children aged 6 to 12 years. Correlations and multivariate analyses were used to determine associations between summed scores for model constructs.ResultsCaretakers and children perceived a significant difference in taste between white and pro-vitamin A rich cassava. Both preferred pro-vitamin A rich cassava over white cassava because of its soft texture, sweet taste and attractive color. Knowledge about pro-vitamin A rich cassava and it's relation to health (‘Knowledge’ ((β = 0.29, P = <.01)) was a strong predictor of ‘Health behavior identity’. Worries related to bitter taste and color (‘Perceived barriers 1’ (β = −0.21, P = .02)), the belief of the caretaker about having control to prepare cassava (‘Control beliefs’ (β = 0.18, P = .02)) and activities like information sessions about pro-vitamin A rich cassava and recommendations from health workers (‘Cues to action’(β = 0.51, P = <.01)) were the best predictors of intention to consume pro-vitamin A rich cassava.ConclusionsPro-vitamin A rich cassava is well accepted by school children in our study population.
