Lieutenant Colonel Dr Rifa Tshivhase, Head of the Department of Surgery at 3 Military Hospital in Bloemfontein, addressed graduates within the Faculty of Health Sciences at the University of the Free State on 10 December 2024.
Momentous and joyous – these are some of the words used to describe the December 2024 graduations at the University of the Free State (UFS). In celebration of the academic achievements of its students, the UFS hosted graduation ceremonies at the Callie Human Centre on its Bloemfontein Campus from 9 to 10 December 2024.
Prof Anthea Rhoda, acting Vice-Chancellor and Principal of the UFS, encouraged the graduates to always acknowledge and recognise the significance of this achievement as they transition from being UFS students to being UFS graduates.
Undergraduate and postgraduate achievements
At least 2000 undergraduate qualifications and postgraduate qualifications were conferred. As such, there were some standout academic achievements across the sessions. For instance, Itumeleng Pooe received his Advanced Diploma in Theology cum laude, making him the only graduate in the Faculty of Theology and Religion to receive his qualification with distinction during these graduations. In addition, Dr Bobuin Jr Valey Gemandze Oben – at just 28 years old – was the youngest PhD graduate from the Faculty of Law at the graduation ceremony, which took place on the morning of 9 December 2024.
Conferring Honorary Doctorates
Some highlights from these graduations were the recipients of honorary doctorates, as well as the keynote speakers. The Faculty of Economic and Management Sciences (EMS) at the UFS conferred an honorary degree on Prof Murray Leibbrandt, Research Chair in Poverty and Inequality Research in the Southern Africa Labour and Development Research Unit (SALDRU) at the University of Cape Town (UCT). In addition, the Faculty of The Humanities at the UFS conferred an honorary degree on HE Bineta Diop, Special Envoy of the Chairperson of the African Union Commission on Women, Peace, and Security.
On the final day of the graduations, graduates within the Faculty of Health Sciences at the UFS were addressed by Lieutenant Colonel Dr Rifa Tshivhase, Head of the Department of Surgery at 3 Military Hospital in Bloemfontein. In her address, Lieutenant Colonel Dr Tshivhase encouraged and challenged the graduates to actively seek out good in the world.
As the December 2024 graduations concluded, several of the graduates within the Faculty of Health Sciences indicated that the most memorable moments in the session were the cheers and applause they received as they walked across the stage.
UFS researchers are producing various flavour and fragrance compounds

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.
