Nutritious food and added value - Flagship Project 4 overview, ISTRC 2018

  1. 1. O c t o b e r 2 0 1 8 Flagship 4: Nutritious Food & Added Value TAWANDA MUZHINGI • RTB ISTRC MEETING
  2. 2. Flagship Project 4: Objectives To support the fuller, equitable, and sustainable utilization of RTB crops for healthier diets and improved income opportunities To overcome constraints that have hindered RTB crops from entering urban markets, perishability, bulkiness, perception as of low social status, and limited post-harvest investment
  3. 3. Post-harvest innovationGender integration • Validation of the Gender in Value Chains Analytical Tools for Expanding Utilization of Roots, Tubers and Bananas and Reducing Their Postharvest Losses Post harvest loss management • Testing the efficacy of two technologies for increasing the shelf-life of fresh cassava roots to increase the value to growers, traders and consumers. Animal feed from cassava peels and sweetpotato silage • Longitudinal study on designed pig feed resources farmers use and what are the current feeding practices on smallholder farms. RTB Scaling P1 cassava peels work IITA. Food product development • Studies to investigate the potential of developing novel food products using yam flour from D. alata. • Market demand and consumer profile for products based on by-products from the native potato chips processing in Ecuador. Cross cutting research
  4. 4. Highlights key expected outputs/outcomes for 2018 • Review of user preferences for boiled and fried sweetpotato in Uganda and the East African region at large. • Knowledge of the impact of interaction of packaging materials and storage time on consumer preferences of cassava, yam or plantain-based food • RTB food composition data, and the tools to access and exploit it, underpin the development and implementation of local food and nutrition policies, regulatory measures, labelling and health advice. • Food Safety: Heavy metal contents and microbial counts of plantain chips/flour dried traditionally and under the solar tent will be determined and compared. • Yam flour from 150 ascensions were analysed for proximate composition and used to develop NIRS Calibration profile and Spectral data base for fresh yam and cassava for selected traits ( eg DM, starch and its properties) • Validation of postharvest losses in the sweetpotato value chain in Uganda. • Feasibility of replacing wood residues with plantain peels and cassava peels as substrate for commercial production of mushrooms under two different climates: tropical mountainous 1500-1700 & 1000 m a.s.l • Assessment of banana peels, cassava leaves and other RTB by-products to reduce greenhouse gas emissions of cattle, when used as ingredients in

  9. 9. Biofortified cassava: Provide rural households with nutritious biofortified cassava that will help reduce VAD, particularly among pregnant and lactating women and children under 5 years of age Taleon, Victor, et al. "Carotenoids retention in biofortified yellow cassava processed with traditional African methods.” Journal of the Science of Food and Agriculture (2018). The results indicated that biofortified boiled cassava could be an effective food product to improve provitamin A carotenoids intake in areas were vitamin A deficiency exists, and processing of chikwangue and fufu should be improved before promoting biofortified cassava in vitamin A deficient areas with high cassava
  10. 10. SW4.4: Nutritious sweetpotato A series of wheat breads have been prepared by substituting wheat flour with 10, 20, 30, 40 and 50% sweetpotato puree. • Sensory and physical attributes highlight the acceptable nature of the prepared breads. • The presence of beta-carotene significantly retards the starch digestion suggesting the usefulness of thus prepared breads in addressing the glycemic issues as well.
