Shoes project
University of the Free State Biokinetics student, Maralé Hoft, with pairs of tackies they have collected so far for the needy kids of Eersteling Primary School. More donations are still needed.

She could not bear the sight of little children coming to school barefoot. So, a University of the Free State Biokinetics student went on a campaign to help find tackies for the children.

Touched by the sight of barefoot kids
Maralé Hoft encountered this situation when she and her colleagues went to the Eersteling Primary School to present sports-based physical activity programmes at the school as part of their curriculum programmes.

The school, which is located on the outskirts of Bloemfontein, about 10 kilometres from town in the Kellysview area, caters for children from Grade R (pre-school) to Grade 4, which are “obviously very young.”

“It became worse when we had to do some sports activities with them having no shoes on – I felt like I had to do something to help them,” she said.

More tackies still needed

Hoft says she has a target of about 100 children, but “we have so far only managed to get about 50 pairs of second-hand tackies.” 

“I would like to ask anyone who can contribute a pair of tackies for this age group to please do so, so that we could help the less privileged. Their shoe sizes range from size 10 (kids) to size 5 (regular),” she said.

Dr Monique de Milander, Lecturer in the Faculty of Health Sciences’ Department of Exercise and Sport Sciences, says: “All help will be most appreciated, as it would be ideal to have enough pairs to give every child a pair. We are worried that if we don’t have enough, we cannot give it to them, as it would not be fair if only a handful of children get a pair and the rest don’t.”

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.
