Legae first-year residents welcomed on UFS South Campus

On 27 January 2018, several dozen eager first-year students and a large number of their parents crowded into the venue at the Legae residence on the South Campus of the University of the Free State (UFS). They were welcomed by Gali Malebo, the Residence Head, Prof Daniella Coetzee, the Principal of South Campus, and Prof Francis Petersen, the Rector and Vice-Chancellor of the UFS.

Prof Coetzee exhorted the students to show their seriousness about studying by giving their best and being accountable for their own learning experience. She said that she enjoyed the very positive vibe from the excited and enthusiastic students. Prof Petersen also addressed the students and advised them to make full use of the facilities made available to support and assist especially first-years.

Gali Malebo said of the occasion: “I am pleased that what we planned was so successful, and I feel blessed that both Prof Petersen and Prof Daniella [Coetzee] were present to share such beautiful moments with us. I am grateful to my team of Residence Assistants who worked very hard to make sure that everything was in order. They received several expressions of appreciation from parents for their hospitable, welcoming spirit and for making the first-years feel at home, especially for those who travelled from far.”

Prof Coetzee concluded with these words, “The UFS is a space for freedom, opportunities, and responsibilities. Use each day to reach out for knowledge. The university is a place where you are supposed to be active in seeking out the knowledge you need, a place where you are supposed to struggle and strive in order to excel. Do not give up until you have explored the limits of your intellectual ability. We expect much of you, and you should expect much of us.”

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.
