Dr Thandi Gumede
Dr Thandi Gumede graduated with a PhD in Polymer Science. She is from Intabazwe, Harrismith.

The Qwaqwa Campus of the University of the Free State was a hive of activity on 17 and 18 May 2019, when over 800 degrees, diplomas, and certificates were conferred on deserving achievers. These included six PhDs and 14 master’s degrees across the four faculties.

Congratulating the graduates on both days, was Africa’s youngest PhD and Industrial Psychology lecturer, Dr Musawenkosi Saurombe, and Prof Francis Petersen, Rector and Vice-Chancellor.

Be like heat

Dr Saurombe started her address by relating her school journey that saw her starting Grade 1 at age 5, thus later matriculating at the age of 15, having skipped Grades 3 and 10. She went on to emphasise the importance of building an honourable character.

“As a graduate, you will soon realise that your degree is useless if you do not have character,” she said to an attentive audience that continued to marvel at her remarkable school history. She encouraged graduates to be like heat that cannot be seen but can only be felt. “Noise can often be seen and heard, but it cannot be felt. However, while heat cannot always be seen, it is always felt. Be like heat and may your presence always be felt,” she said.

Do not focus on yourself

Prof Francis Petersen also encouraged graduates to look beyond their degrees by developing a set of critical values.
 
“For us as the university, this ceremony is not just about your degrees. It is about the values that you must live by,” he said. “As a graduate of the UFS, do not just believe what you are told. Ask questions and engage critically. Secondly, do not just focus on yourself. Remember that you are part of a community and it is your responsibility to make our world a better place for others. You need to be socially responsive to the needs of your community. Thirdly, remember that integrity plays a very important role. This will determine how others value you,” he said.

The two ceremonies also saw three current SRC members graduating. They are Lebohang Miya (BEd FET – Accounting and Business Studies), Duduzile Mhlongo (BA – Geography and isiZulu), and Mhlongo Sinemfundo (BA – Geography and isiZulu).

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.
