Prof Bonang Mohale.


The executive management of the University of the Free State (UFS) and the university community extend heartfelt congratulations to Prof Bonang Mohale on his appointment as President of Business Unity South Africa (BUSA). 

“Prof Mohale’s extensive expertise and experience in leadership roles, contributions to the growth of many multinational companies, and involvement in education and the business sector, will undoubtedly strengthen the ties between various sectors and civil society, and further contribute to the stabilisation and growth of South Africa,” said Prof Francis Petersen, UFS Rector and Vice-Chancellor, in his congratulatory letter to Prof Mohale. 

BUSA’s role in influencing policy and legislative development for inclusive growth and employment, and in building an enabling environment for the creation of a vibrant, diverse, and globally competitive economy that harnesses the economic and human potential in South Africa, is well documented. This potential resides in our higher education institutions in the form of our students, future graduates, and graduates who are the building blocks for the development of South Africa. 

At a time when our country is facing a social and economic crisis, we are confident that BUSA will consider the perspectives across sectors with a view to creating partnerships, collaboration, and co-creation and further play an integral role in our higher education institutions for the benefit of our students. 

“Prof Mohale’s support to the UFS is appreciated, especially his role as Chancellor and his contribution towards our Thought-Leader and Global Citizen programmes, through which important national and global issues are addressed.
 
We wish Prof Mohale every success in his endeavours, particularly as President of BUSA,” said Prof Petersen.

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.
