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 a Vitamin A rich 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 product will be on sale after  Uganda Bureau of Standards (UNBS)’ approval around the second week of May 2022.

OFSP Puree

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 chapati, bread, cakes and can be used in juice making to reduce the cost of production and enhance quality,” he said.

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 per week. 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.

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.

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.
  • In addition, indirect beneficiaries will be the urban and rural consumers who will have access to nutritious and healthier bakery products compared.
