Developed considerable expertise in the physicochemical characterization of food materials and hydrocolloid systems. Served as a collaborating scientist and coordinator on several projects/research teams.  Coordinator for Short Course in Food Hygiene and Short Course in Applied Rheology.Currently working on the evaluation of some underutilized crops for potential food applications. Isolation and characterization of polysaccharides as functional ingredients in food and/ or pharmaceutical systems. These include the physical, chemical, and technological properties of starch, pectin, and gums found in underutilized sources for their beneficial applications in improving livelihood and global food and nutrition security. The research on okra pectin as an emulsifier in chocolate production is promising and holds the potential to be a major breakthrough for the chocolate industry, the pharmaceutical industry, and the okra value chain upon completion and implementation of further ongoing studies. This has led to the African Agri-food Knowledge Transfer Partnership (AAKTP) Grant Award (AAKTP-13910 / IUK Project No. 10097922). Thus, the Knowledge Transfer Partnership (KTP) exists between The University of Huddersfield (UoH), UK & KNUST, as well as the University of Health and Allied Sciences (UHAS), Ho, and Cocoa Processing Company (CPC) Limited. The project aims to develop novel, sustainable plant pectins from locally sourced, low-market-value species for use in chocolate-based products.Prof. Agbenorhevi has successfully supervised 9 PhD,  10 MPhil, 50 MSc, and 83 BSc Students/Theses. He has over 80 publications in peer-reviewed journals, 108 conference papers, 2 books, 2 book chapters, and 15 other articles, including handbooks/training manuals/magazines.RESEARCH AREAS/EXPERIENCESWEBSITE/RESEARCH PROFILE LINKS
