Sikhululekile Luwaca named 100 Young Mandelas of the future
Sikhululekile Luwaca was recently named as one of 100 Young Mandelas of the future by News24 for his embodiment of Nelson Mandela’s characteristics.
On Tuesday 3 July 2018, News24.com announced the 100 Young Mandelas of the future. Among those nominated was Sikhululekile Luwaca, a former president of the Student Representative Council (SRC) at the University of the Free State (UFS).
 
“It is humbling. I embrace collective action and it would be unfair not to appreciate all the great minds I have encountered over the years and had the privilege to work with. Our individual progress can never be separated from that of the community. It is no longer I that lives, but us, we,” said Luwaca.

Six million readers nominated 1 000 South Africans from all walks of life who could be considered Mandelas of the future. Luwaca emerged in the Visionary category as one of the 100 who made the cut. The initiative was inspired by what would have been Nelson Mandela’s 100th birthday on 18 July 2018. “News24 set out to honour 100 young South Africans who embody the characteristics Mandela was best known for,” said a statement by News24.

While he was the SRC president, Luwaca’s office played a critical role in raising R1.2 million for underprivileged students. He continues to make major strides as the current chairperson of the UFS African National Congress Youth League (ANCYL). 

His social and political influence goes back to when a 13-year-old Luwaca founded an association that sought to address school dropouts in rural areas. In high school, the young philanthropist established an organisation that collected and distributed food for needy elders of Cathcart township in the Eastern Cape. For five years Luwaca served the Student Christian Organisation as chairperson. In 2013, he co-founded the Ubuntu School Project that donated 100 full school uniforms to Phomolong High School learners in Tembisa.

Later on as a UFS student, Luwaca helped found the Hand2Hand Student Association which drives fundraising initiatives, as well as the collection of non-perishable food items and second-hand textbooks for disadvantaged students. In 2015 he was elected a Residence Committee representative for House Outeniqua and SRC: Dialogue and Association. 

Luwaca was instrumental in facilitating a series of dialogues on transformation such as the Fees Must Fall movement and the Shimla Park incident.

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.
