Mak-CAES BioInnovate Project Registers Significant Achievements
Smallholder farmers in Uganda and Kenya produce a variety of fruits, traditional and exotic vegetables, spices, and herbs that have unique nutritional, nutraceutical and functional properties. However, the value derived from these crops is limited due to postharvest losses, seasonal production, limited value addition and market access problems. Developing and applying affordable food preservation technologies could reduce postharvest losses by up to 68%. Additionally, food preservation by drying not only prolongs shelf life, but it also minimizes storage, transportation and packaging costs.
About the project
In 2017, Makerere University through the Department Agricultural and Biosystems Engineering at the College of Agricultural and Environmental Sciences (CAES) received funding under the BioInnovate Africa Programme Phase II to implement a project titled;“Adaptation and Promotion of Refractance Window Drying Technology (RWDT) for Production of High Quality Bio-products”. The RWDT uses heat to dry fruits and vegetables, while maintaining the nutritive qualities. With RWDT, liquid foods, purees or slices are dried on one side of a thin plastic film, whose other side is in close contact with hot water at temperatures below boiling point. The plastic film, usually in the form of a conveyer, is susceptible to infrared radiation, therefore allowing thermal energy to be transferred from the water to the food. Transmission of infrared radiation stops when the food is dry, and the product scraped off the conveyor. The temperature of the product remains relatively low during drying, resulting in better quality retention due to reduced moisture content and inhibited microbial growth. The heated water is recycled, further improving thermal efficiency of the system.
Project duration and objectives
The three-year project worth 750,000 USD had been scheduled to end in December 2020 but was extended to June 2021 due to the outbreak of COVID19 and the subsequent restrictions aimed at curbing the spread of the pandemic. The development objective of the project was to create new business opportunities in food value addition and agro-processing equipment fabrication. The project specifically aimed to develop a heat drying technology that is affordable yet yields high quality products, even from heat sensitive materials. It also aimed to; support local fabricators to make quality Refractance Window Drying equipment suitable for use by local agro-processors; improve the quality of products, mainly fruits, vegetables and herbs on the Ugandan& Kenyan markets; minimize post-harvest losses; increase the use of locally produced food ingredients derived from fruits, vegetables and herbs; and to enhance collaboration among farmers, agro-processors, researchers and support agencies.
Project activities
Working with various partners namely; Jomo Kenyatta University of Agriculture and Technology, Kenya Industrial Research and Development Institute (KIRDI), TONNET Agro-engineering Company Limited, East Africa Nutraceuticals Ltd (EAN), Food and Nutrition Solutions Ltd (FONUS) and the Ministry of Trade, Industry and Cooperatives, Uganda, Makerere University implemented several activities under the project. These included designing and fabrication of low cost dryers, techo-economic evaluation of the dryers, evaluation of the refractance window dried products, assessment of the capacity of agro-processors and fabricators; training of farmers, agro-processors, and fabricators; and training of graduate students.

According to Prof. Muyonga, plans are underway to develop a Memorandum of Understanding between Makerere University and a private firm to oversee the utilisation of Refractance Window Drying equipment at MUARIK for commercial production of value added foods. “There are also plans to facilitate three agro-machinery companies – 2 in Uganda and 1 in Kenyato produce Refractance Window Dryers under the guidance of Makerere University and Kenya Industrial Research and Development Institute (KIRDI). We also hope to engage development agencies to support farmer groups to procure Refractance Window Dryers,” he noted while explaining the research team’s commercialization arrangements.
Explaining the design process of the Refractance Window Dryer, Dr Julia Kigozi said the technology is mechanically simple, cheaper to purchase, energy efficient with high drying speed and low operational costs, and ensures retention of product quality. Dr Kigozi revealed that steps were being taken to promote the use of RWD technologies through Jazi Agro-processing Solutions Limited. Jazi Agro-processing Solutions Limited is a private company that specializes in food processing and doubles as a consultancy in regards to agro-processing solutions with a goal of promoting the agro-processing sector in Uganda. The company carries out training and mentoring on fundamentals necessary for the operation of agro-processing industries.
During the meeting, Mr. Raymond Mutumba shared the outreach and dissemination programmes conducted by Food and Nutrition Solution Ltd (FONUS) with regard to the Refractance Window Drying Technology.Based at the School of Food Technology, Nutrition and Bio-Engineering, Makerere University, FONUS provides consultancy services in the fields of food value addition, community nutrition, food handling and hygiene, post-harvest handling of foodstuffs, facilitation of farmer group learning processes and project evaluations.The main purpose of FONUS’ engagement with the project was to promote uptake of the RWD technologies among end users. This was done through a series of engagements with farmer groups, small and medium agro-processors, and processors that utilise the RWD products and ingredients in foods.
Community engagements undertaken by FONUS included a situational analysis on the potential utilization of the Refractory Window Drier Technology in food value addition, training agro-processors in the use of hybrid RWD, and training of medium and large scale agro-processors in the use of RWDT in the drying of fruits and vegetables. In addition, FONUS conducted trainings on the use of RWDT products and ingredients and flavours in foods, and assessed the marketability of RWDT products.
According to Mr. Mutumba, the community engagements revealed that the RWDT presented a viable solution for preservation of fruits and vegetables in Uganda. The engagements also revealed that the incubatees were more willing to adopt the technology compared to already established processors. It was also discovered that more research needs to be done in RWDT energy efficiency if the RWDT products are to have competitive process on the market. The team called for government support to increase uptake of the technology, noting that individuals and small processor groups may not easily afford it.
Addressing participants, the Vice Chancellor, Prof. Barnabas Nawangwe appreciated SIDA for the enormous support extended towards research and training programmes at Makerere University. “The University has reached the 1,000 mark of staff with PhDs, and almost half of these have been trained under SIDA,” he noted. In addition to other research programmes, SIDA supports the BioInnovate Africa Programme. The Vice Chancellor applauded the Department of Agricultural and Biosystems Engineering at CAES for the commendable initiative aimed at improving the quality and increasing shelf life of agricultural products in Uganda. “The products produced out of this initiative can be major exports for Uganda. We need to move towards commercializing our products. We however need to improve our marketing skills,” he explained while cautioning the research team on the importance of marketing the products. He also advised researchers to make use of the Intellectual Property Management Office at the University to patent their products.
Commenting on the significance of agriculture in the development of the economy, the Vice Chancellor said the CAES has a great role to play in improving the sector. Appreciating the research output at CAES, he called on the College to take lead in the establishment of a central business incubation unit to promote research and innovation at Makerere.
