Dr Ioannis (Yannis) Zabetakis has studied for his BSc in Chemistry in the Univ. of Athens and in 1993 he moved to UK where he spent 8 years; he studied for a PhD in Food Science in the Univ. of Leeds, did postdoctoral research on alkaloids in the Univ. of Durham and worked as a Lecturer in Food Chemistry in the Univ. of Leeds. During his lectureship in Leeds (1998-2001), he also studied for a M.Ed. in Food Chemistry. From 2003 to 2015, he had been working in the laboratory of Food Chemistry in the Univ. of Athens (2003-2008 as a Lecturer of Food Chemistry, 2008-2015 as an Assistant Professor of Food Chemistry and Associate Professor of Food Chemistry).
Ioannis joined the University of Limerick (UL) in 2015 as Lecturer on Food Lipids and in 2020 he was promoted to Senior Lecturer.
Since September 2018, he is the Head of the Department of Biological Sciences in UL.
He is also involved in consulting and auditing (as a Lead Auditor) food industries. As a hobby, he likes to write articles on food safety in specialised food sector magazines and newspapers.
The focus of his team is towards the development of functional foods and nutraceuticals against inflammation.
Ioannis has been the co-author of 6 books on food sciences (HACCP, food chemistry, food technology, crisis management and food legislation) in Greek, has edited a book on marine oils in 2015 and has published over 90 peer-reviewed articles (Scopus h-index 27). He is also co-inventor of two patents.
With his team in UL, they published in 2019 a book entitled, The Impact of Nutrition and Statins on Cardiovascular Diseases, for Elsevier and they are now editing a book on Functional Foods, for Elsevier.
At UL, Ioannis is a member of:
He teaches in the programme LM068 “Food Science and Health” undergraduate modules (five in total) in all four years of the programme. More information on his teaching can be found here.
The research focus of his group is in three interrelated areas:
1. Polar lipids and human health
2. Food security
3. Emerging hazards in water and food and how they are linked to inflammation
In the 1st area, the group is interested in isolating and identifying functional polar lipids of food origin that have strong anti-inflammatory activities, i.e. the potential to stop the onset of inflammation and thus the development of CardioVascular Diseases (CVDs). These lipids can be further exploited in various ways, ranging from developing novel health claims (according to EFSA EU guidelines) for foods till producing novel neutraceuticals and pharmaceuticals. (Lordan and Zabetakis 2017; Megalemou et al. 2017; Sioriki et al. 2016)
In the 2nd area, the group works with Fish feeds and animal feeds.
For fish feeds, we study ways how to increase food security by decreasing our dependency on fish oil (FO). The sustainability of FO is a threat for aquaculture and there is a worldwide search for alternative sources of lipids that can used in fish feeds.
For animal feeds, they evaluate different ways of how to exploit by products of olive industry, brewing and distilling processes and use these by-products to enrich fish feeds. Our ultimate scope is to develop sustainable manufacturing processes of novel animal and fish feeds and also final products (fish; pig; chicken etc) with improved cardioprotective properties. (Nasopoulou et al. 2014) (Nasopoulou et al 2018 / Patents)
In the 3rd area, the interest is in studying the effect of anthropogenic pollution on food chain and how these pollutants (focusing to Cr and Ni) can be uptaken by food tubers. They are now investigating the role of these heavy metals in (promoting) inflammation and thus their link to the onset of a plethora of inflammation-triggered diseases. (Stasinos et al. 2014; Stoikou et al. 2017).
