UFSAfricaWeek - Focus on Dr Tariro Kamuti
Dr Tariro Kamuti, postdoctoral fellow in Africa Studies.

“Africa is a continent endowed with vast natural resources and the ways through which these resources are governed for the development of the continent and the upliftment of its people are critical.” These are the words of Dr Tariro Kamuti a postdoctoral fellow at the Centre for Gender and Africa Studies at the University of the Free State. 

Believer of advancing Africa and African scholarship
Dr Kamuti said it was important to celebrate Africa Week because “as a continent, we have come a long way through so much sacrifice to be where we are today”. 

He said Africans needed to celebrate their achievements attained so far by remembering where they had come from while embracing change and focusing on the future with hope. 

“Pausing to reflect on the issues facing the continent in order to chart the way forward through celebrating African Week is a good thing to do,” he said.

Dr Kamuti supports the notion of growing African scholarship on the continent to “to turn the tide and reflect on what really transpires”. 
“It is incumbent upon us to own and tell the African story,” he said.

Personal experience attributed to interest in Africa Studies

Dr Kamuti’s experiences and roots as a child of peasant farmers shaped his world view and drove his passion towards a career in Africa Studies as a scholar and researcher.

“My research work seeks to offer a fresh perspective on the policy processes surrounding the governance of the private wildlife ranching sector in South Africa,” he said. “It is an interesting research angle when considering the role of wildlife ranching in shaping the agricultural and environmental policies and land-use patterns in a situation where the land question itself is highly contested from various perspectives.

“Issues relating to wildlife ranching can be used as a lens to analyse challenges facing democratic South Africa,” Dr Kamuti said.

UFS researchers are producing various flavour and fragrance compounds
2015-05-27

 

The minty-fresh smell after brushing your teeth, the buttery flavour on your popcorn and your vanilla-scented candles - these are mostly flavour and fragrance compounds produced synthetically in a laboratory and the result of many decades of research.

This research, in the end, is what will be important to reproduce these fragrances synthetically for use in the food and cosmetic industries.

Prof Martie Smit, Academic Head of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, and her colleague Dr Dirk Opperman, currently have a team of postgraduate students working on the production of various flavour and fragrance compounds from cheap and abundantly available natural raw materials. 

Prof Smit explains that most of the flavours and fragrances that we smell every day, originally come from natural compounds produced mainly by plants.

“However, because these compounds are often produced in very low concentrations by plants, many of these compounds are today replaced with synthetically-manufactured versions. In recent times, there is an increasing negative view among consumers of such synthetic flavour and fragrance compounds.”

On the other hand, aroma chemicals produced by biotechnological methods, are defined as natural according to European Union and Food and Drug Administration (USA) legal definitions, provided that the raw materials used are of natural origin.  Additionally, the environmental impact and carbon footprint associated with biotech-produced aroma chemicals are often also smaller than those associated with synthetically-produced compounds or those extracted by traditional methods from agricultural sources.

During the last four years, the team investigated processes for rose fragrance, vanilla flavour, mint and spearmint flavours, as well as butter flavour. They are greatly encouraged by the fact that one of these processes is currently being commercialised by a small South African natural aroma chemicals company. Their research is funded by the Department of Science and Technology and the National Research Foundation through the South African Biocatalysis Initiative, the DST-NRF Centre of Excellence in Catalysis and the Technology Innovation Agency, while the UFS has also made a significant investment in this research.
