The Council of the University of the Free State (UFS) approved the lifting of the institution’s COVID-19 Regulations and Required Vaccination Policy with immediate effect.

“Since the declaration by the Government on 22 June 2022 that the COVID-19 regulations will be repealed, the UFS has conducted a risk assessment to determine the risk of exposure to staff and students. From the assessment, it was clear that the university’s COVID-19 infections are currently a low risk,” said Prof Francis Petersen, Rector and Vice-Chancellor of the UFS.

Factors that contributed to this low risk include the following:

  • No COVID-19 positive cases among UFS staff and students have been reported in the past month.
  • The high number of vaccinations among UFS stakeholders. In addition, the current national immunity level of the total South African population is high.
  • Certain faculties and postgraduate students are currently proceeding with hybrid/online learning, which minimises the risk of possible COVID-19 infections on the university’s three campuses.
  • In its correspondence of 23 June 2022, the UFS urged all staff and students to continue wearing masks should they have comorbidities and/or symptoms of illness, thus safeguarding other stakeholders.

“We believe that COVID-19 no longer poses an immediate threat to the safety of our staff and students, and that the pandemic is at a stage where they should take responsibility for their own safety. This can be mainly ascribed to the success of the implementation of the policy. Staff and students who still wish to wear masks are urged to do so at their own discretion. Those who have not yet been vaccinated against the virus and have no

known condition preventing them from doing so, are advised to get vaccinated for their own safety and protection,” said Prof Petersen.

The UFS COVID-19 Regulations and Required Vaccination Policy was approved by the University Council on 26 November 2021 and implemented on 6 December 2021. The university commenced restricting unvaccinated individuals from accessing its campuses as of 14 February 2022.

“If the national regulatory environment with respect to COVID-19 is changing to such an extent that the policy needs to be re-implemented, the university’s executive management will act accordingly, and hence the COVID-19 Regulations and Required Vaccination Policy remains a policy of the university as approved by the UFS Council on 26 November 2021.” said Prof Petersen.

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.
