Dr. Mahunu is an associate professor at the University for Development Studies, Ghana. He is a full-time lecturer at the Food Science and Technology Department. He obtained a BSc in Agricultural Technology (Horticulture option) from the University for Development Studies, Ghana; an MSc in Pomology, the Kwame Nkrumah University of Science and Technology, Ghana; and a PhD in Food Science and Biological Engineering, Jiangsu University, China. His main research areas include studies on the mechanisms of action of microbes and other bioprotectants (such as natural plant extracts) acting as biocontrol agents of postharvest pathogens of horticultural and fruit crops, the optimization of the activity of these agents, mycotoxins in foods (e.g., patulin in apples), prevention induction, monitoring, and detoxification of mycotoxins in postharvest fruits and vegetables, improvement of quality and food safety practices in the food production systems, functional foods, and food product development.
