Defender Refiloe Nketsa is one of four Kovsies chosen for the South African U21 netball team.
With no less than four Kovsies in the South African Under 21 netball team, the near future for this sport at the University of the Free State (UFS) is certainly on the bright side.

Chanel Vrey, Refiloe Nketsa, Rolene Streutker, and Boitumelo Mahloko will be in action for the Baby Proteas, as the team is known, in a challenge series. The team will battle the President’s XII (a South African A team) and Uganda from 25 March in Cape Town. 

They all played for the Free State senior side last year. Vrey and Streutker also played for the Baby Proteas against international competition in 2019.

Mahloko – a former Kovsie – and Nketsa have also represented South Africa at junior level in the past. They were team members in the national U16 team in 2017, and a year later Mahloko made the U20 team and Nketsa the SA U18 team.

Khanyisa Chawane will also be in action in the series, playing for the Proteas, while former Kovsie captain Alicia Puren has been chosen for the President’s XII.

Meanwhile, two hockey players, Saré Laubscher and Zimkhitha Weston, have been picked for the South African U21 women’s hockey team. They would have participated in the African qualifying tournament in Ghana at the end of March. This tournament has, however, been postponed to January 2022. 

This is the third consecutive year that Laubscher has made the team. Weston, a former Kovsie, played for South Africa at the 2018 Youth Olympic Games in Argentina.

The African Hockey Qualifier serves as qualification for the Junior World Cup, which is scheduled for December in Potchefstroom. South Africa has already qualified as hosts for the Junior World Cup, but the African crown is up for grabs in Ghana.

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.
