You can now enjoy a glass of wine or a slice of cake made from the invasive Mathenge tree, thanks to innovative research from the University of Nairobi.
The university is currently showcasing by-products from the Mathenge tree (Prosopis juliflora) at the ongoing Nairobi International Trade Fair.
Data from the Ministry of Environment, Forestry and Climate Change says Mathenge tree was introduced in Kenya in 1948 to combat landscape degradation and desertification.
It has since become invasive, spreading at the rate of 15 per cent annually across 22 counties with 16 more at risk.
Native to Central and South America, the tree has colonised millions of acres in Kenya.
Despite its invasive nature, researchers are finding ways to add value to it.
“We’ve demonstrated that we can transform the Mathenge tree into valuable food products," said Dr Samuel Mose, a researcher in the Department of Food Science, Nutrition and Technology at the University of Nairobi.
“By drying and milling the seeds, we can make cakes and bread. To make wine from Mathenge, we ferment the seeds and then filter the mixture.”
In addition to wine and baked goods, the university is also showcasing other by-products such as juices from the invasive cactus species and value-added products from sea moss, a vegetable harvested from the Indian Ocean.
“The sea moss is rich in minerals, vitamins and antioxidants and it may provide various health benefits,” Mose said.
“We’re also utilising underappreciated fruits such as guava to create additional products, including yogurt.”
Joseph Mugo, chairman of the Agricultural Society of Kenya, Nairobi branch, said the society has made efforts to promote agricultural innovation at this year's Trade Fair.
Some of the initiatives being showcased include establishing business incubation centres for micro, small and medium enterprises and providing training on the latest agricultural technologies.
There are also demonstration gardens at Jamhuri Park that offer year-round training for farmers in climate-smart agriculture, fostering sustainable farming practices.
The Nairobi International Trade Fair, which began on September 23 and runs until September 29 at Jamhuri Park Showground, has attracted more than 500 global and local exhibitors from various sectors, including agriculture, manufacturing, housing and education.
Mugo said the society is committed to promoting climate-smart initiatives in agriculture and trade.
“The Nairobi International Trade Fair serves as a crucial platform for sharing knowledge in agriculture and trade, ensuring exhibitors present new innovations and technologies,” he said.
“Through live demonstrations, workshops and interactive training sessions, the fair supports development in agriculture, trade and related sectors, aligning with the national government’s agenda for sustainable economic growth.”
