UFS vegetable garden
A variety of vegetables, including beans, spinach, onions, and carrots, are sheltered in 40 vegetable boxes in the two 300 m² tunnels opposite the Welwitschia Residence on the Bloemfontein Campus.

At the University of the Free State (UFS), research findings have indicated that 59% of students do not know where their next meal will come from. The recent COVID-19 pandemic contributed to the unemployment rate of 34,9%, adding to the likelihood of our students being affected even more by food insecurity. 

One of the initiatives the university has created to address the issue, is a vegetable production and training programme. The purpose of the programme, which was established by the Department of Sustainable Food Systems and Development, KovsieACT, and the Food Environment Office, is to teach students how to produce vegetables. 

A variety of vegetables, including beans, spinach, onions, and carrots, are sheltered in 40 vegetable boxes in the two 300 m² tunnels opposite the Welwitschia Residence on the Bloemfontein Campus. Not only is this initiative providing students with fresh produce that supplements the food parcels they receive from the Food Environment Office through the No Student Hungry Project. It also provides them with the opportunity to get involved on a voluntary basis in the food production process, including the planting and harvesting of the vegetables. 

Food production is an important skill in growing one’s own food. Moreover, it is also a valuable skill for students to transfer to their communities back home.

From mid-August through to the end of October is planting season for a number of vegetables. Starting spring on a high note, the Department of Sustainable Food Systems and Development, KovsieACT, and the Food Environment Office invited food security activist, Thabo Olivier, to address the university community and provide some valuable guidelines to grow your own food in innovative ways. 

Date: Thursday 1 September 2022
Time: 13:00
Venue: Thakaneng Bridge

Invest in your future and join the event, which will include hands-on harvesting from the vegetables gardens as well as a food demonstration.

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.
