UCU alum’s innovation reduces post-harvest losses

UCU

By Kefa Senoga
In 2017, the father of Jean Paul Nageri planted more than 100 acres of bananas in Busia, eastern Uganda. As is usually the norm, towards harvest time, a middleman promised to buy all the bananas at harvest. The harvest time came, but the middleman never showed up. The result? Most of the bananas either got rotten in the garden or were sold at a give-away price.

The pain of that loss was so unbearable for Nageri that the next year, he was in the laboratory, working out a solution to mitigate the gravity of the depletion his father suffered. He suspected there was a solution, but did not know exactly what it was. And the tests in the laboratory led him to something that was more like putting into practice the course he had studied at Uganda Christian University (UCU), where he received a Bachelor of Agricultural Science and Entrepreneurship.

Nageri sought to extend the shelf life of many fruits and vegetables by slowing down their rate of spoilage while being kept at room temperature without any form of refrigeration – a move that democratizes food storage and removes barriers to enable everyone to keep food fresh, regardless of whether you have a cold room or not. In Uganda, room temperature is about 25 degrees Celsius (77 Fahrenheit).

So, how does Nageri’s innovation work?

He explained that using the skins of oranges, mangoes, bananas and other fruits in the lab, he was able to extract compounds, which he later turned into powder. The powder is blended with water, which is then used for coating the fruits and vegetables. The coating, which he has named Ka Fresh and is produced by his firm, Sio Valley Technologies, is edible.

“Most of the knowledge I am applying now is what I obtained in class at the university,” he said. “I am working with other scientists who are also applying the same knowledge in biotechnology.”

For this innovation, Sio Valley Technologies was early this year awarded the Most Innovative Export company at the third annual Uganda/EU Business Summit. Nageri received the award from Uganda’s Prime Minister Robinah Nabbanja. The Head of the European Union Delegation to Uganda, Ambassador Jan Sadek, was also present at the awards gala.  

The World Food Program estimates that as of last year, more than 333 million people in the world were facing acute levels of food insecurity; they did not know where their next meal would come. The situation is compounded by the fact that the cost of delivering food assistance was at an all-time high because of the increase in the prices of food and fuel.

Despite the hunger situation, the Food and Agriculture Organization of the United Nations estimates that 30-40% of total food production is lost before it reaches the market. But with the Ka Fresh solution, Nageri aims to overcome this challenge, so that farmers can have more bargaining power over their produce while in the market without fear of it getting rotten while on the shelf.

Some fruits and vegetables that have been coated with Nageri’s solution, he says, are now able to stay fresh for up to three times their natural shelf life. Nageri says tests in the laboratory have indicated that tomatoes that have been coated with Ka Fresh, for example, are able to stay for more than 70 days under room temperature without refrigeration.

UCU’s Nageri Develops Air Freight Solution

Nageri’s innovation should come as good news for exporters who are currently scratching their heads for solutions to the rising cost of air freight. Currently, according to the World Bank, it costs 12 to 16 times more to transport a commodity through air than sea and yet exporters opt for air transport because some commodities cannot last the more than 30 days it takes most of the ships to travel from African ports to Europe.

The journey to the Ka Fresh innovation saw Nageri team up with a friend, Lorna Orubo, to make tomato jam as a student at UCU and then mayonnaise, as his final-year project to meet the requirements for the award of his degree.

 “If you are building the right solution to a challenge, capital will always follow you and the right people will always want to surround themselves with you,” Nageri says, noting that for now, he is more focused on fine-tuning his innovation than looking at what he stands to benefit from it.

UCU showcases at the Agricultural Exhibition

By Eriah Lule

The Faculty of Agricultural Science, Uganda Christian University (UCU), participated in the inaugural Agricultural Education Show, which was held at the Jinja show grounds.

The Uganda National Farmers Federation, Operation Wealth Creation and the Ministry of Education and Sports organized the exhibition in collaboration with the Ministry of Agriculture, Animal Industry and Fisheries.

The exhibition ran on a theme: farming for a prosperous future. This exhibition, according to UNFFE, provides a platform for young people in schools (primary and secondary, farm schools, and other tertiary institutions) to showcase and compete in innovative ideas and enterprises in which they are involved both in and out of school.

The exhibition, which started on Wednesday, June 8, and ended on Sunday, June 12, attracted over 200,000 people to visit the different stalls. They attracted young agriculturalists from primary to institutions of higher learning that exhibited in different arenas of farming.

Ruth Buteme, a lecturer at the Faculty, noted that the Faculty of Agricultural Sciences equips its students with skills in sustainable food production, value addition, marketing, and research. The faculty produces graduates that are model scientists and agri-prenuers, able to identify and solve challenges in the community.

The faculty exhibited many projects, but among them was the Cricket project, where students are making use of food wastage to make food for crickets.

Petrina Kiiza, a fourth-year student pursuing a Bachelors of Food Science and Technology on this project, said that crickets are rich in nutrients like proteins and minerals and act as feed for poultry and as a delicacy in some regions of Uganda. However, the cost of feed remains a challenge to cricket farmers. Therefore, her project is aimed at formulating an alternative cricket feed through food waste material.

The faculty exhibited a rabbit-vegetable integrated urban garden system that is targeting urban farmers with limited space. The system harbors a rabbit cage and crates on the side, creating space for the growing of vegetables. 

According to Ronald Mupuya, a teaching assistant at the faculty and an alumnus of the Bachelors of Agricultural Science and Entrepreneurship,

“The system helps a farmer shoot two birds with one stone; a farmer is able to earn quick money from the vegetables in the short term as the rabbits mature for sale. In addition, the rabbit excreta acts as a good source of manure for the farmer’s vegetable garden, while any waste from the vegetables can be used to feed the rabbit,” he said.

Asaba Catherine, a fourth-year student of Food Science and Technology, was also among the exhibitors. She makes both mango and strawberry jam using chia seed as a replacement for pectin, which is costly for most producers. Asaba believes that from the exposure she got from the exhibition, she has gained feedback that will enable her to better her product.

“I believe that with the ideas and feedback received, I will be able to improve my product to satisfy my customers. I also made networks with suppliers and potential customers,” she said.

Ada Nalubowa, a fourth-year student of Food Science and Technology, also exhibited her chia seed doughnuts at the show. According to Ada, Chia is a potential replacement for eggs in modern baking due to its quality and low prices.

“Some people are even allergic to eggs, but they won’t eat baked goods, which is where I come in with a solution of chia seeds to cater for people allergic to eggs but also provide an alternative ingredient,” she said.

Another product exhibited by the faculty was clean indigenous vegetable seed that has been cleaned and produced through various participatory breeding activities at the faculty. 

The faculty through a number of donor funded projects continues to conduct research on indigenous vegetables so as to avail varieties that are high yielding, have a longer shelf life and are resistant to drought, disease and pest stresses. The faculty has also trained over 300 farmers and schools in small scale and commercial vegetable production for improved income and nutrition through its community engagement program. She added that the faculty hopes to become a center of excellence in vegetable breeding.

Emmanuel Igar, Assistant Academic Registrar Admissions and Student Records, stated that the faculty members who participated in this exhibition also informed the public about what UCU is doing in terms of research and student innovation.

“The faculty has networked with various exhibitors, shared knowledge and if handled well may result into increased student numbers and partnerships for future projects that will enhance the country’s agricultural sector,” Igar said.
