Prof. John H. Muyonga Delivers Professorial Inaugural Lecture
Theme: Circular Bio-economy: Applications to the Agri-food Sector
In his Lecture, Prof. John H. Muyonga highlighted the nutritional value of waste from agri-food products and explained the measures that can be taken to minimize wastage
The Inaugural Lecture
A lot of what is thrown away as waste from agri-food products contains nutrients that are crucial for the body’s immunity. This was revealed by Prof. John H. Muyonga during his Professorial Inaugural Lecture held on 23 June 2023 at the Yusuf Lule Central Teaching Facility, Makerere University. Organized under the theme: Circular Bio-economy: Applications to the Agri-food Sector, the lecture was graced by the University Top Management led by the Vice Chancellor, Prof. Barnabas Nawangwe, and attended by academics and administrators from the 10 Colleges of Makerere, as well as the family of Prof. Muyonga. Prof. Muyonga.
The health benefits of waste from agri-food products
In his presentation, Prof. John H. Muyonga, a Professor of Food Science at the Department of Food Technology and Nutrition, College of Agricultural and Environmental Sciences (CAES), Makerere University revealed that waste of plant origin contains nutrients and a wide diversity of non-nutrient compounds (phytochemicals), that are associated with health benefits. “The non-starch polysaccharides from fruits, vegetables and whole cereals help prevent cancer, hypertensive, hypoglycemic, and hypochloresterol. Carotenoids found in coloured fruits and vegetables equally prevent hypertensive, cancer, obesity, and support vision. The phytosterols in cereals and legume cereals bran serve as antioxidants and help in the prevention of colon cancer and hypochloresterol effect, hypertensive, pytic acid, and kidney stone formation,” Prof. Muyonga explained, further highlighting valuable components of waste from selected food crops. Citrus peels and seeds contain Pectin, essences, ethanol, D-limonene, limonoids and flavonoids. Mango peels and kernels contain fibre, vitamins, carotenoids and polyphenols, kernal fat and pectin. Passion fruit seeds and rind contain pectin and linoleic acid. Banana peels have phenolics, beta-carotenoids, anthocyanins, fiber, amino acids, polyunsaturated fatty acids, vitamins, flavonoids and potassium, whereas Avocado seeds and peels contain carbohydrates, proteins, lipids, fibres, minerals, phenolics, flavonoids, and fatty acids. Prof. Muyonga also highlighted a number of valuable components in waste from animal-based foods emphasizing the need to minimize wastage. According to Prof. Muyonga, increased adoption of circular bio-economy principles can help minimise wastage. Circular bio-economy entails reuse of as much bio-waste as possible, resulting in multiple value added products from a given volume of harvested biomass. Circular bio-economy can be used to explore the use of waste streams as raw materials for products such as new food products, feed, fuel, industrial ingredients, bio-plastics, biopharmaceuticals, bio-cosmetics, enzymes, nutritional supplements, nutraceuticals, materials for tissue repair, plasma substitutes, microbes and adsorbents. Circular bio-economy decreases dependency on natural resources by encouraging sustainable goods that generate food, feed, materials and energy using biological resources.
Minimising wastage of agri-food products
During his 26 years at Makerere University, Prof. Muyonga has been key in developing research capacity on previously under researched foods including grain amaranth, jackfruit, pumpkins, Solanum anguivi (katukuma), and Nile perch, among others. Working with a number of partners, he has conducted research and come up with various technologies to minimize wastage in agri-food products. Given the Nutraceutical properties of jackfruit pulp, he has conducted research and developed protocols for drying jackfruit pulp using the Refractance Window Drying technology. He has conducted studies on pumpkin and produced shelf stable flours from seed and pulp of pumpkins. Flour from the seeds is high in phytochemicals and it is recommended for weight control. Together with his research team, they have processed sweetpotato products into shelf-stable value added products. He has also conducted research on jackfruit pectin. The work entailed extracting pectin from jackfruit and assessing its properties. He also worked on the production and utilisation of passion fruit powder. Other key activities included; Tamarind seed analysis and utilisation- Tamarind seed powder was found to be suitable for use as ingredient to enhance nutraceutical properties of juices and cookies; Nile Perch collagen and gelatin studies – Collagen has a unique amino acid profile that gives it peculiar properties, including the ability to form gels when dissolved in water; Nile Perch oil extraction and Characterisation- Fish oils are rich in omega 3 fatty acids. Omega 3 fatty acids contribute to brain development and protection against cardiovascular diseases, breast, colon and prostate cancer, inflammation, depression, pain and psychosis. He also worked on characterisation of cassava leaf, processing and utilisation. Cassava leaves were found to be high in proteins, carbohydrates, beta-carotene, polyphenols and ascorbic acid.
Future plans
In future, Prof. Muyonga intends to work on the characterization of by-products from more agri-food materials produced in Uganda. He also hopes to work on the application of novel and sustainable technologies in agri-food waste valorisation to improve extraction efficiency, efficacy and limit environmental impact; and to evaluate new applications of components of agri-food waste – e.g. in bio-based packaging and bio-preservation. Prof. Muyonga also plans to undertake policy and techno-economic analysis of valorisation options.
Remarks by the Vice Chancellor
According to Makerere University Vice Chancellor, Prof. Barnabas Nawangwe, an inaugural lecture is an occasion of significance in an academic staff member’s career at the university. It provides professors with the opportunity to share their achievements in research, innovation, engagement and teaching activities before an audience of members of the University community and the general public.
In his address, Prof. Nawangwe congratulated Prof. Muyonga for making all necessary preparations to deliver his Professorial Inaugural Lecture. “This is the way to go as we continue to boost our scholarship, image and reputation.

How transformative education is shaping Africa’s next generation of innovators
The African Union’s Agenda 2063 articulates a clear continental ambition; to unlock Africa’s potential to feed itself and to harness the transformative power of its greatest asset, its people. While natural resources remain abundant and diverse, Africa’s long-term prosperity hinges on the strategic cultivation of human capital through robust, forward-looking education systems.
Like many governments across the continent, the Government of Botswana, the host of the Regional Universities Forum for Capacity Building in Agriculture (RUFORUM)’s 21st Annual General Meeting (AGM), aligns closely with the Sustainable Development Goals of zero hunger and no poverty. It also upholds the collective aspirations of African Heads of State and Government expressed in the Kampala Declaration under the Comprehensive African Agricultural Development Programme (CAADP).
Against this backdrop, the pre-AGM session on transformative education and ecosystem engagement convened hundreds of scholars, policymakers, and thought leaders from Africa and beyond. The discussions underscored a shared urgency that strategic collaboration must move from concept to action if the continent is to confront its pressing challenges of food insecurity, public health vulnerabilities, conflict and displacement, youth unemployment, and the persistent pressures of migration. The message was clear; Africa’s transformation requires not isolated interventions, but integrated, interdisciplinary solutions.
In fulfilling the CAADP agenda, universities stand at the forefront. They must leverage every available opportunity to generate workable, evidence-based solutions through science, technology, and innovation. However, they cannot act alone. National Agricultural Research Systems, the private sector, civil society, and development partners must each play an indispensable role in strengthening Africa’s education and agricultural systems. Together, these institutions form the ecosystem that will determine whether Africa can translate its ambitions into tangible progress.
The Youth Dividend
Since its establishment at Makerere University in Uganda in 2004, RUFORUM has supported the training of more than 3000 students across the continent at PhD, Masters, undergraduate and Technical and Vocational Education and Training (TVET) level. These scholars, drawn from diverse African countries and hosted in universities across the region, represent a deliberate investment in building Africa’s scientific capacity and advancing pan-African collaboration. Notably, 98% of RUFORUM-supported graduates continue to work within their home countries or regions, reinforcing national and regional development efforts.
A key contributor to this impact is the Mastercard Foundation supported initiative, Transforming African Agricultural Universities to Meaningfully Contribute to Africa’s Growth and Development (TAGDev2.0). This programme strengthens universities, Technical, and Vocational Education and Training (TVET) institutions to drive inclusive, equitable, and climate-resilient transformation of agriculture and agri-food systems. Through experiential learning, practical skills development, and youth empowerment, TAGDev enhances the ability of young Africans to engage meaningfully in agriculture as innovators, leaders, and entrepreneurs.
Across both TAGDev 1.0 and 2.0, thousands of young women and men have been equipped to establish profitable enterprises and create employment opportunities within their communities.
This transformative impact was evident during a keynote address by Dr. Yeukai Mlambo from the MasterCard Foundation followed by a panel session where four young entrepreneurs and beneficiaries of RUFORUM MasterCard supported programmes, shared their journeys. Their enterprises span a wide spectrum. From improving and multiplying high-quality potato seed in Nakuru Kenya by Winnie Wambugu, to equipping differently abled persons (PWDs) with agronomy and entrepreneurship skills in Uganda by Zena Saliru, to skilling refugees in the west Nile region of Uganda by Gordon Victor Akejo to supporting out-of-school youth to become self-reliant by Kato Omia. These stories illustrate not only the ingenuity of Africa’s youth but also the importance of sustained investment in higher education and innovation ecosystems. They embody the youth dividend that Africa stands to gain if it continues to nurture the potential of its young people.
A moment Africa cannot afford to miss
As the conversations by the young entrepreneurs have made clear, Africa stands at a pivotal moment. The continent’s aspirations captured in Agenda 2063, the SDGs, and the CAADP commitments cannot be realised through intention alone. They demand systems that elevate human capital, institutions that collaborate rather than compete, and education models that prepare young people not merely to seek opportunity but to create it.
The stories shared by emerging entrepreneurs and young scientists are more than inspiring anecdotes; they are proof points. They show that when universities are empowered, when partnerships are genuine, and when young people are trusted with the tools and mentorship they need, transformation is already underway.
The scale of Africa’s challenges requires an equal scale in commitment by Governments, universities, research organisations, the private sector, and development partners who must deepen investments in higher education, innovation ecosystems, and youth-focused initiatives. Failure to do so risks squandering one of the continent’s most powerful assets, its demographic dividend.
Africa must therefore double down on transformative education and ecosystem-led collaboration. The momentum witnessed in Botswana should not end with the AGM. It should mark the beginning of renewed resolve to equip Africa’s young people with the skills, networks, and support they need to lead the continent’s next chapter.
The future is already taking shape in laboratories, fields, innovation hubs, and classrooms across the continent. It is time to scale what works and ensure that Africa’s brightest minds are empowered to build the strong and prosperous nations they envision. Collectively, we shall all achieve the Africa that we want.
