Abe Bailey Bursary victor
“I believe in self learning,” says 2018 UFS Abe Bailey victor, Nkahiseng Ralepeli.
The Abe Bailey Trust is a leadership-development opportunity that targets university students or junior lecturers who are academically strong and have shown exceptional qualities of leadership and service. Recipients of the bursary are required to have a good record of accomplishments, not only on campus but also in a broader social context, where they function as an integral piece of a select and highly-skilled group of individuals.

Ralepeli, the over-achiever

Final-year Law student, Nkahiseng Ralepeli, embodies this exact description and exemplifies the essence of distinction and merit when it comes to who he is. Ralepeli  who has represented the university at various international debate platforms, an alumni of the F1 programme to Thailand and other leadership programmes such, recently, International Youth Leadership Conference (IYLC) programme in Prague, will represent the University of the Free State (UFS) during the Abe Bailey Travel Bursary tour in the UK in December 2018. He, along with 16 other candidates from other South African tertiary institutions, will participate in the tour for its full duration and will take part in the exciting developmental programme that is planned.

With an intense but fruitful leadership-training schedule, he said he was looking forward to meeting the British members of parliament as well as other persons of stature in the British government.

Travelling: A catalyst for critical thinking

Ralepeli, who was also 3rd overall Kovsie Dux student, underlined that he truly enjoys travelling. He has subsequently mastered the art of constantly positioning himself among the best academically and socially, and this has aided his mission to trot the globe extensively, which he has been doing since his junior years.

A man of value

“I have a small yet select and impactful network of people in my life who play an influential role in reminding me during times of triumph that, while it is important to celebrate, each win is just a step towards the ultimate goal of success,” said Ralepeli. 

He emphasised the importance of the roles played by those close to him, describing them as “my double-edged sword who played a crucial role in carving out the inner Nkahiseng, who, hopefully, will do great things”. The Kovsie Dux believes that those you surround yourself with, channel the kind of energy that will either make or break you.

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.
