Karla takes netball world by storm
Karla Pretorius, vice-captain of the Protea netball team, has become a leading player in world netball.

The University of the Free State (UFS) has produced a number of exceptional netball players over the years, but none quite on the level of Karla Pretorius, who is widely considered as probably the very best in her position.

 

A whole new level


Pretorius, who is completing her postgraduate studies in Dietetics, was already deemed one of the best when she left for Australia at the end of 2016; however, she has since risen to a whole new level. The Protea vice-captain plays for the Sunshine Coast Lightning in Australia’s Suncorp Super Netball league, the world’s leading competition. She is scheduled to return there again next year. Karla comfortably leads the stats with a total of 50 intercepts and was named in the Team of the Tournament.

 

According to the former Australian coach, Norma Plummer, who is now at the helm of the Proteas, “Karla currently has to be one of the best, if not the best, goal defenders playing at this moment in time.”

 

Karla’s ability to come through with speed-anticipating interceptions is something that is so exciting to watch. She is very versatile and can switch from one-on-one to split circle or other defensive styles, explained Norma. She says Karla is light in stature but physically very strong.

 

Keep on improving

 

According to Pretorius, who played for the Kovsies between 2009 and 2015, playing in an environment where every possible aspect gets attention – with emphasis on detail – has benefited her immensely. “Everything is done so professionally to eventually push you to become the best possible player.” Karla explained that she experiences challenges in many fields of her life but has the chance to play with and against the best players with different skills, which helps her to keep on improving and bettering her craft.

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.
