In the quiet farming communities of Nasarawa State, a humble legume known locally as the Nasarawa Egon bean has long been part of daily diets. Often overlooked beyond its region of origin, the jack bean has remained on the fringes of Nigeria’s agricultural and food innovation landscape. Today, however, that narrative is changing—thanks to the pioneering work of Dr. Feyisola Ajayi.
A food scientist and lecturer at the Federal University Gashua in Yobe State, Dr. Ajayi is championing research that could transform how indigenous crops are used in modern food systems. Her work places the jack bean at the center of a growing global conversation on sustainable proteins, functional foods, and plant-based innovation.
Armed with a PhD in Food Science and Technology from the United Arab Emirates University, Dr. Ajayi has dedicated years of rigorous research to unlocking the functional potential of plant proteins, particularly those derived from jack and lima beans. Her studies go beyond basic nutrition, delving into how proteins behave under different processing conditions and how their structures can be modified to improve food quality.
Through carefully standardized protein extraction techniques, she has demonstrated that jack bean proteins can function as effective emulsifying and gelling agents—key properties needed in food formulation. These functionalities influence texture, stability, and mouthfeel, making the proteins suitable for use in a wide range of food products, from meat alternatives to nutrient-dense formulations.
One of her most innovative contributions lies in the development of cold-set protein gels. By using acid and divalent inducers, Dr. Ajayi has pioneered methods for fabricating plant-protein hydrogels with promising encapsulation and controlled-release properties. These systems open new possibilities for food-grade delivery of nutrients and bioactive compounds, bridging the gap between food science and advanced functional ingredient design.
Her research interests also extend into the emerging field of nutraceuticals. Dr. Ajayi has explored bioactive peptides derived from soybean and chia seed hydrolysates, evaluating their drug-likeness properties—an approach that links traditional food research with pharmaceutical and therapeutic applications.
For Dr. Ajayi, the motivation behind her work is deeply rooted in sustainability and local relevance. “Beyond being a staple legume in Nasarawa, the jack bean holds immense promise as a sustainable protein source,” she explains. “My goal is to show that indigenous crops can play a global role in food innovation.”
With a growing portfolio of scholarly publications and international collaborations, Dr. Ajayi’s work is gaining recognition as part of the global shift toward plant-based solutions. By combining indigenous food knowledge with cutting-edge science, she is helping to diversify protein sources, reduce reliance on imported ingredients, and promote food systems that are both health-focused and environmentally sustainable.
In elevating the jack bean from a regional staple to a scientifically validated functional ingredient, Dr. Feyisola Ajayi is not just advancing research—she is redefining the value of local crops in shaping the future of food.
