Stable atmospheric environments and near perfect weather conditions were the main reasons for the establishment of the Boyden Observatory a few kilometres outside Bloemfontein. This astronomical research observatory and science education centre is managed by the Department of Physics at the University of the Free State (UFS).

With the newly acquired astronomical spectrograph for the Boyden Observatory 1,5-m telescope, scientists will be able to gain visual access to both the Northern and Southern Hemisphere skies.

Collaboration with expert in stellar spectroscopy 


The spectrograph, mainly developed and built by Dr Richard Gray, will be used collaboratively for astronomical research by the UFS and the Appalachian State University (ASU) in North Carolina, where Dr Gray is based. 

Dr Gray is a world-renowned expert in stellar spectroscopy and leading author of one of the most influential textbooks on stellar spectroscopy, Stellar Spectral Classification, with co-author Christopher J Corbally.

Dr Gray recently received a Fulbright Scholarship from the Fulbright Foundation to spend a full year in the UFS Department of Physics, where he will lecture several Astronomy classes and do research in collaboration with personnel of the UFS Astrophysics Research Group. He will also lead the assembly of the instrument over the next few weeks, working with personnel and students in the Department of Physics as well as the UFS Instrumentation Division.

According to Prof Pieter Meintjes, Senior Professor from the UFS Department of Physics, some components of the instrument have been developed and constructed by the university’s Instrumentation Division, with key components purchased from funding by the Directorate: Research Development at the UFS.

Unique capability in infrastructure 

“The availability of a sophisticated instrument of this nature on the 1,5-m telescope will place the UFS Astrophysics Group in an elite bracket in terms of the available infrastructure for astronomical research,” said Prof Meintjes.

He explained: “The combined polarimetric-spectroscopic capability in one single instrument is unique. Combined with the fact that it is hosted on a research instrument that is utilised and maintained exclusively by the UFS Astronomy Group in the Department of Physics, gives this group a competitive edge in relation to most international astronomy groups.” 

The instrument is valued at close to R1,5 million.

According to Prof Meintjes, the instrument will be mounted at the backend of the UFS Boyden 1,5-m telescope and will allow them to do simultaneous polarimetry and spectroscopy of astronomical sources. “This is vital for the research we are working on,” he said.

International collaboration and student development

The instrument also brings with it the possibility of forging international collaborations for research as well as student development. “This can advance the stature of the UFS as an internationally respected research-led tertiary institution,” said Prof Meintjes. 

The possibility of making the UFS Boyden 1,5-m telescope completely remote-controlled, is being investigated. “This will serve the observational needs of researchers from both the UFS and the ASU, with researchers at ASU able to access the telescope for their own in-house research programmes. The availability of such an instrument on the UFS 1,5-m telescope also opens up the possibility to accommodate visiting researchers from ASU or elsewhere in the world at Boyden,” said Prof Meintjes.

UFS to investigate implementation of quality-monitoring system for SA food industry

The University of the Free State (UFS) will be investigating the implementation of a quality-monitoring service for the South African food industry. 

This was decided during a workshop to discuss the external quality monitoring in the edible oil industry of South Africa, which was recently held at the UFS.

Major role players in the fast-food sector like Nando's, Spur, Captain
Dorego's, King Pie Holdings, Black Steer Holdings, etc and various oil
distributors like Felda Bridge Africa, Refill Oils, PSS Oils and Ilanga Oils attended
the workshop. Also present was Mrs Ina Wilken, Chairperson of the South African National Consumer Union (SANCU) and key-note speaker of this workshop. She represented the consumer.  

These role players all pledged their support to the implementation of this quality- monitoring system for the whole food industry. 

The decision to implement this system follows the various malpractices reported in the press and on TV concerning food adulteration (eg the recent Sudan Red Scare), misrepresentation (eg olive oil scandal exposed in 2001) and the misuse of edible frying oils by the fast-food sector. 

“One of the basic rights of consumers is the right to safe food. Consumers must be protected against foods and food production processes which are hazardous to their health. Sufficient guarantee of the safety of all food products and food production processes should be implemented. It does not help to have adequate food standards and legislation and there is no manpower to do the necessary investigation or monitoring,” said Mrs Wilken.

The South African Fryer Oil Initiative (SAFOI), under the auspices of the UFS Department of Microbial, Biochemical and Food Biotechnology, currently monitors edible oils in the food industry and makes a seal of quality available to food distributors.

“Last week’s decision to implement the quality-monitoring system implies that we will now be involving also other departments in the UFS Faculty of Natural and Agricultural Sciences who are involved in various aspects of the food chain in an endeavor to implement this quality monitoring system,” said Prof Herman van Schalkwyk, Dean:  Faculty of Natural and Agricultural Sciences at the UFS and one of the main speakers at the workshop.

Prof van Schalkwyk said that the main aim of such a system will be to improve the competitiveness of the South African food industry.  “It is clear that the role players attending the workshop are serious about consumer service and that they agree that fraudulent practice should be monitored and corrected as far as possible.  Although some of the food outlets have the capacity to monitor the quality of their food, it may not seem to the consumer that this is an objective process.  The proposed external monitoring system would counteract this perception amongst consumers,” said Prof van Schalkwyk.

The workshop was also attended by representatives from SAFOI and Agri Inspec, a forensic investigation company collaborating with inter-state and government structures to combat fraud and international trade irregularities.

Agri Inspec has been working closely with SAFOI for a number of years to test the content of edible oils and fats.  “Extensive monitoring and control actions have been executed in the edible oil industry during the past four years to ensure that the content and labeling of oil products are correct.  Four years ago almost 90% of the samples taken indicated that the content differed from what is indicated on the label.  This has changed and the test results currently show that 90% of the products tested are in order. However, to maintain this quality standard, it is necessary that quality monitoring and educational campaigns are continuously performed,” said Mr Joe Hanekom, Managing Director of Agri Inspec. 

“The seal of quality presented by SAFOI should also be extended to include all the smaller oil containers used by households,” Mrs Wilken said.

The SAFOI seal of quality is currently displayed mainly on some oil brands packed in bigger 20 liter containers, which include sunflower oil, cottonseed oil, palm oil etc which are used by restaurants and fast food outlets.  “Any oil type is eligible to display the seal when meeting certain standards of authenticity.  In order to display the seal, the distributor must send a sample of each oil batch they receive from the manufacturer to SAFOI for testing for authenticity, ie that the container’s content matches the oil type described on the label. This is again double checked by Agri Inspec, which also draws samples countrywide from these certified brands from the end-user (restaurant or fast food outlets). If in breach, the seal must be removed from the faulty containers,” said Prof Lodewyk Kock, Head of SAFOI.

“It should however be taken into account that oils without a seal of quality from the UFS can still be of high quality and authentic. Other external laboratories equipped to perform effective authenticity tests may also be used in this respect,” said Prof Kock.

“It is also important to realise that any oil type of quality such as sunflower oil, cottonseed oil, palm oil etc can be used with great success in well controlled frying processes,” he said.

Further discussions will also be held with the Department of Health, the SA National Consumer Union and Agri Inspec to determine priority areas and to develop the most effective low-cost monitoring system.
