Nkahiseng Ralepeli will join the Rhodes Scholarship cohort of 2019.

Aspiring lawyer and political prodigy, Nkahiseng Ralepeli, will soon join a cohort of Rhodes Scholarship recipients at the University of Oxford in the UK later this year. He completed his LLB at the University of the Free State (UFS) in 2018, and it comes as no surprise that this young achiever has his eyes set on greater heights.

As a student, Nkahiseng was always a cut above the rest, with his involvement in non-governmental organisations such as Corruption Watch and Debate Afrika, where he used debating to not only educate youth in South Africa but to engage various social ills that plague the country in whichever way he could. He represented the UFS at various debating tournaments such as the Pan-African Universities Debating Championships and the World Universities Debating Championships.

“This is something I’ve wanted for an incredibly long time. Receiving this scholarship is so important, and makes me feel that all my efforts and work have been validated. What I’ve learned is that regardless of the situation you’re born into, rich or poor, hard work is rewarded. I hope this experience will help me realise my dreams and career goals, but most importantly I want to have a significant impact in whatever space I find myself in and on the people I encounter,” said Nkahiseng.

As an Abe Bailey Bursary recipient, he is deeply interested in the transformation of African political theory and the establishment of various structures in the development and maintenance of African ‘infant’ democracies and post-civil wars. He later hopes to pursue a career in South African politics. His list of achievements keeps getting longer as he adds to it the Rhodes Scholarship. The UFS is truly proud to have an alumnus of this high calibre.

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.
