Prof Emmanuel Temitope AKINTAYO obtained B.Sc Chemistry and M.Sc Analytical Chemistry University of Ibadan in 1987 and 1991 respectively. He bagged the Ph.D in Applied Chemistry at the Federal University of Technology, Akure in 1999. Prof Akintayo's research is in the area of Applied Chemistry with particular interest in structural and compositional analysis of vegetable oils, application of vegetable oils in Oleochemicals and synthesis of polymers from renewable resources . He has about 20 years experience in teaching, research, management and leadership in Applied Chemistry. Commencing his career as an Assistant Lecturer, Prof Akintayo was promoted over the ranks up till the level of Full Professor of Applied Chemistry in 2007. He has published over fifty articles in internationally peer reviewed journals. He is a member of many professional organizations. He had served at the University of Ado-Ekiti in various capacities, as Head of Department of Chemistry, Director of Pre-Degree Science Program, Member of University Development Committee, and presently he is the Director of the University's Centre for Research and Development. He is a committed University teacher who is dedicated to human resource development and the promotion of Science and Technology in Africa.

E T Akintayo (2004)  Characteristics and composition of Parkia biglobbossa and Jatropha curcas oils and cakes.   Bioresour Technol 92: 3. 307-310 May  
Abstract: Parkia biglobbossa (PKBS) and Jatropha curcas (JTC) seeds were analysed for their proximate composition. The seeds oils were analysed for fatty acid, lipid classes, sterols and physicochemical characteristics. Proximate analysis revealed that the percentage crude protein, crude fat and moisture in PKBS were 32.40%, 26.525% and 10.18% respectively and 24.60%, 47.25% and 5.54% in JTC. Campesterol, stigmasterol, beta-sitosterol, Delta5-avenasterol and Delta7-stigmasterol were identified in the seed oils, but beta-sitosterol was most abundant, constituting 71.9% in JTC and 39.5% in PKBS. JTC oil had 72.7% unsaturated fatty acids with oleic acid predominating, while PKBS had 62% unsaturated fatty acids with linoleic acid being the most abundant. Results of lipid classes showed triglyceride as the dominant lipid species in the seed oils. Physicochemical analysis of the seed oils showed that they could be classified as semi drying oils and that they could be found applicable in alkyd resin and soap manufacture.

E T Akintayo, E Bayer (2002)  Characterisation and some possible uses of Plukenetia conophora and Adenopus breviflorus seeds and seed oils.   Bioresour Technol 85: 1. 95-97 Oct  
Abstract: Two non-conventional seeds, Plukenetia conophora (PKCP) and Adenopus breviflorus (ADB) were analysed for their proximate, fatty acids, sterols composition and physico-chemical characteristics. Crude protein was 25.65% for PKCP and 28.25% for ADB. ADB had lower moisture content (4.5%) than PKCP (8.0%) indicating that the former has better shelf life. Oil yields of the seeds were 49.58% for PKCP and 56.22% for ADB. The major sterols were stigmasterol and beta-sitosterol in PKCP and ADB respectively. PKCP oil had 98.8% unsaturated fatty acids with linolenic acid predominating (70.1%) while ADB had 85.1% unsaturated fatty acids with linoleic acid being most abundant (65.3%). The very high saponification and iodine values of PKCP oil suggest its utilisation in alkyd resin, shoe polish, liquid soap and shampoo production. There is the possibility of using ADB oil in these regards as well as for edible purposes.
