Mak Commissions Orange Fleshed Sweet Potato Puree Processing Unit
Makerere University College of Agricultural and Environmental Sciences (CAES), represented by Dr. Richard Miiro, from the Department of Extension and Innovation Studies on 6th April 2022 commissioned an Orange Fleshed Sweet Potato (OFSP) Puree Processing Unit at Lishe Products Limited in Kasangati, Wakiso District. With support from BioInnovate Africa Programme Phase II Initiative, the College received funding for a project titled: OFSP Puree for Bakery Applications in East Africa for Nutrition, Post-harvest Loss Management, and Youth & Women Economic Empowerment, to work with a private sector entity to operationalize a processing unit that makes bakery and fried foods ingredient from Vitamin A rich OFSP. Lishe Products Limited was the private sector partner selected to host the processing unit after competitive scrutiny, although Makerere University takes responsibility for the technical assistance, research and training components in the project. Partner companies/institutions included: Euro Ingredients Kenya – PI; International Potato Centre Kenya – Co-PI, Hawassa University Ethiopia, Makerere University Uganda, and Women’s Bakery – Rwanda.
The OFSP Puree project started in 2018 and ended on 30th March 2022. The overall goal of the project was to contribute to improved nutrition and incomes in Uganda, Ethiopia, Tanzania, Rwanda and Kenya (consortium countries) through a profitable and vibrant OFSP-based food value chain, and to promote the commercialization of Orange-fleshed Sweet potato (OFSP) puree products through demand creation, value addition and processing in baked and fried bakery products.
Specific objectives included:
- Increasing the productivity and production of OFSP among smallholder farmers linked to the processing activities in select regions of consortium countries
- Establishing OFSP puree processing factories in Uganda, Tanzania, Rwanda, and Ethiopia
- Developing market chains for OFSP-puree based bakery food products in consortium countries
- Piloting shelf-stable (12-24 months) OFSP puree for use in bakeries, culinary (coffee shops, hotels and restaurants) and ready to eat food formulations in Kenya using hot fill thermal processing technology
In his remarks, Dr. Richard Miiro, the Country Project Team Leader appreciated BioInnovate Africa for funding the project. He expressed gratitude to Prof. Barnabas Nawangwe, Vice Chancellor of Makerere University and the entire CAES leadership for trusting them with the project, and Lishe and other partners for the job well done during the project implementation process. According to Dr. Miiro, the main aim of the OFSP project was to promote commercialization of the Orange fleshed potatoes developed by Ugandan scientists as well as establishing a Puree processing factory. OFSP Puree is a solution to Bakery Applications in East Africa: For Nutrition, Post-harvest loss management and youth & women Economic Empowerment. “Sweet Potato Puree is an ingredient used in chapatti, bread, cakes and can be used in juice making to reduce the cost of production and enhance quality,” he said.
The Chief Guest, His Worship Muwonge Tom, Mayor Kasangati Town Council congratulated Makerere University, partners and Lishe Products Limited upon the achievement. He appreciated BioInnovate Africa and Makerere University for considering them and promised to team up with residents in the bakery business to promote puree.
The Principal College of Agricultural and Environmental Sciences was represented by Dr. Okello Ongom, Director Makerere University Agricultural Research Institute Kabanyolo (MUARIK) who extended appreciation to BioInnovate Africa for funding the research initiative, and the Puree project team for the innovation. He also acknowledged the contribution of the project team towards transforming Makerere into a research-led University as per the 2020-2030 Strategic Plan.
In her remarks, Ms. Sonia Mwandime, Director Lishe Products Limited thanked BioInnovate Africa and Makerere University for giving her the opportunity to host the Processing Unit at her business premises. “Without the support of Makerere University, we wouldn’t get this,” she said. In collaboration with Makerere University, Lishe Products Limited produces 250kgs of puree. Puree is a gluten-free product used in Chapati, bread, porridge, food, juice and fried products. You do not have to add sugar since the potatoes are already sweet. 700 grams of puree when added to 1 kg of wheat flour can yield 45 chapati as compared to 35 chapati got without adding puree.
Mr. Kabagambe Stephen from Uganda Chamber of Commerce applauded Makerere University for championing business incubation in the country. “Puree innovation is in line with the current government priority programmes under the National Development Plan (NDP III) and its associated with the Parish Development Model,” he noted. According to Mr. Kabagambe, prices of wheat are already high and with these substitutes, it will not only increase production but also address the market challenges. He cited the health benefits of puree and the need for Uganda Chamber of Commerce together with quality assurance bodies to assist such business initiatives to grow.
Mr. Antonio Magnagi, Jonisa Bakery noted that there are significant improvements in bakery products when mixed with puree. “Puree changes the physical appearance of Bakery products & increases profits. It increases profit margins compared to the products baked without puree.” Mr. Magnagi commended Makerere University for the partnerships geared towards improving livelihoods.
According to Mr. Kwikiriza Norman, CIP Nairobi, Puree is a good substitute for wheat, promotes food security, and nutritious with Vitamin A.
Phases of project Implementation
Phase 1: Developing a commercially viable prototype. EIL (Euro Ingredient Limited) has OFSP puree products prototypes and equipment designs ready to be piloted in East Africa
Phase 2: Preparatory period. EIL will work in Ethiopia, Rwanda, Tanzania, and Uganda with partners to identify key OFSP puree products for their markets. EIL will work on equipment, factory design, and food product development. CIP and university partners will conduct consumer acceptance and willingness to pay, as well as gender and nutrition impact studies.
Phase 3: Start-up period. The puree factories will be established in Ethiopia, Tanzania, Uganda, and Rwanda by OFSP farmers engaged in CIP projects and start producing OFSP varieties. OFSP puree bakery products will be launched and promoted in consortium countries for rapid uptake.
Phase 4: Shelf-Stable OFSP puree trials in Kenya: In Kenya, the OFSP puree bread value chain has been successfully operating over the past three years with the involvement of CIP, Organi Limited, Euro-Ingredients, and Tuskys supermarkets. An OFSP puree processor in Homa Bay county (Organi Limited) makes puree and supplies frozen puree to Tuskys and Naivas Supermarket bakeries in Nairobi.
OFSP Puree Project Beneficiaries
The direct beneficiaries of the project are to be mostly OFSP smallholder women farmers (15,000 targeted) in consortium countries, since most of the sweet potato production is carried out by women. They, and their families will benefit in the following ways:
- OFSP women smallholder farmers in consortium countries will directly benefit through creation of markets for the OFSP fresh roots and hence income.
- Smallholder farmers’ post-harvest losses from OFSP will be significantly reduced because of increased marketing opportunities from OFSP puree processors.
- Youths and women in Ethiopia, Rwanda, Uganda and Tanzania will be economically empowered.
- Street vendors, informal bakers, rural bakeries, food outlets, restaurants will have access to a shelf-stable, nutritious, affordable and versatile ingredient and a steady income for their families.

From Campus to Community: Universities Lead Teso in Fight Against Greenhouse Gas Emissions
By John Omoding
When Immaculate Acom inhaled smoke from traditional firewood stoves, it was a daily struggle. Her eyes watered, her lungs ached, and cooking became a source of illness rather than nourishment.
Today, Acom’s home in Aten Village, Odudui Parish, Arapai Sub-county, Soroti District, has transformed into a living laboratory for green energy solutions, a hub where university researchers, students, and local farmers collaborate on practical strategies to combat climate change.
“I used to cough every time I cooked. Now, with a biogas digester built by my husband, I can cook and light our home safely,” she says, pointing to the small green dome beside her house. “This is a relief for all the mothers in the community.”
Bringing Academia to the Grassroots
Acom’s story is part of the TORCH Project, a multi-university initiative involving Makerere University, Busitema University, Kabale University, and the University of Juba. The project seeks to reduce greenhouse gas emissions and promote sustainable practices at the community level.
Unlike conventional environmental campaigns, the TORCH Project emphasizes direct engagement with local communities. Role models within villages are identified and trained in modern agricultural practices, clean energy use, and environmentally friendly living standards.
Dr. Jolly Akullo Oder, TORCH Project Coordinator at Busitema University, explains:
“Our mandate is to go to the community, share knowledge, listen to their challenges, and co-create solutions. This is not about lecturing – it’s about learning together.”
The project’s operational area spans a ten-square-kilometer zone around Busitema University’s Arapai campus, where researchers, students, and community members meet regularly to exchange ideas and implement practical solutions.
A Living Lab for Green Growth
The initiative, branded as a living lab, aims to achieve green growth, rural carbon credits, and the adoption of affordable green technologies.
Dr. Patrick Musinguzi, Principal Investigator from Makerere University, emphasizes the community-centric approach: “We are here to sit at the table with the community, discuss the challenges of global warming and greenhouse gas emissions, and chart a path forward together. Awareness is the first step to action.”
The project focuses on tangible interventions, including biogas digesters, sustainable tree planting, and energy-efficient farming methods, to reduce carbon emissions at the household and community level.
Community Voices: From Awareness to Action
For local farmers like John Michael Elebu, the university outreach is both eye-opening and practical. “I’ve never seen academics come to the community and engage with us so openly. I hope they can provide free improved tree seedlings to support our farming and fight climate change,” Elebu said.
Acom urges men in the community to take an active role in adopting clean energy technologies. Her husband, David Okwi, is among those championing the integration of green technologies into everyday agricultural practices.
“Promoting renewable energy and sustainable farming isn’t just about protecting the environment,” Okwi says. “It also improves health, saves money, and strengthens the resilience of our families.”
Universities as Catalysts for Environmental Change
The TORCH Project represents a unique model of academic-community collaboration, where research and practical application intersect.
Universities provide expertise, training, and access to modern technologies.
Community members contribute local knowledge, labor, and willingness to adopt change.
Together, they tackle climate change, energy poverty, and environmental degradation at the grassroots.
Dr. Akullo notes that the initiative will expand its activities continuously, monitoring outcomes, adapting approaches, and scaling up best practices across Teso and neighboring regions.
Way forward
By turning households into living laboratories, the TORCH Project aims to bridge the gap between knowledge and action.
For residents like Acom and Okwi, the benefits are immediate: cleaner air, reduced health risks, and practical solutions for everyday life. For Teso, the project could serve as a blueprint for climate-smart rural development across East Africa.
“Change begins at home,” Dr. Musinguzi says. “When communities understand the challenges of green gas emissions and know how to respond, the impact spreads far beyond one village or household.” In Aten Village, the hum of a biogas stove and the sight of thriving tree seedlings offer a glimpse of what is possible when universities partner with communities, creating hope for a cleaner, healthier, and more sustainable future.
