Schae-Lee Olckers’
UFS PhD student and food scientist Schae-Lee Olckers’ research could contribute to a stable supply of good quality wheat and bread, even in the face of climate change.

Follow your passion in order to find your purpose. This is the mantra of food scientist and University of the Free State (UFS) PhD student Schae-Lee Olckers, whose research is set to improve wheat quality by identifying which types of wheat are better able to tolerate stress, and which proteins are most important for producing high-quality bread. 
 
“By grasping this, it is possible to ensure that we continue to have a stable supply of good quality wheat and bread, even in the face of climate change,” says Olckers, who believes wheat is one of the most important food grains in the human diet, and one of the most important staple cereal crops in the world.

Her PhD study, ‘The influence of abiotic stress on gluten protein and baking quality in bread wheat’, under the supervision of Dr Angie van Biljon and Prof Maryke Labuschagne in the Department of Plant Sciences, and Prof Garry Osthoff in the Department of Microbiology and Biochemistry, is investigating how different levels of heat and drought stress – mostly due to climate change – affect the gluten protein composition of high-yield bread wheat.

Olckers is a food scientist at StartWell Foods (Pty) Ltd, a non-profit organisation that produces high-quality extrusion products for feeding schemes around the country. The products help to eliminate stunted growth among children.

Her research focuses on examining different types of wheat and investigating how proteins are affected by stressors like heat and drought, to understand how these stressors impact the quality of bread. She uses new proteomic methods to look at the different proteins in the wheat flour, to gain a better appreciation of how gluten proteins react to stress.

In this study Olckers is able to see how the proteins change in the various wheat cultivars, helping us to understand how the different types of wheat perform in baking, and how the proteins affect the final product.

She collaborates with the International Maize and Wheat Improvement Center (CIMMYT) in Mexico, that releases new wheat cultivars for developing countries. Their aim is to develop wheat cultivars that maintain their quality in different environments.  To investigate the performance and characteristics of the seeds, both in the field and in the laboratory, CIMMYT did the field trials, quality assessment, and supplied the seeds for high-performance liquid chromatography (HPLC) and proteomics analysis. 

Finding ways to adapt to climate change

She believes that understanding how these stressors impact the production of bread-baking quality in wheat will help scientists gain important insights into how climate change affects our food supply. 

“Taking into consideration the current and projected intensifying heat and water deficit stresses, it is crucial to improve the understanding of these phenomena in order to implement new breeding strategies for sustainable wheat quality. This research could help us find ways to adapt to climate change and continue to produce high-quality wheat and bread for people around the world,” Olckers says.

An exceptional year at Kovsies — one of the most successful years in academic achievement
2014-12-04

 

The University of the Free State (UFS) had an exceptional year, with many staff members and students performing both nationally and internationally. Considerable progress has also been made in improving the academic standards of the university.

“So far, this has been one of the most successful years in academic achievement. The UFS now has the highest academic pass rate in years, partly as a result of the admission standards which were raised four years ago.

“We now also have the highest rate of research publications, one of the highest publication figures for scholarly books in history, three Mandela Rhodes scholars and several international communication awards”, says Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS.

“The university now attracts top professors from all over the country and other parts of the world and for the first time in many years, two researchers received A-ratings from the National Research Foundation (NRF). This is the first time in the history of the UFS that two A-ratings were awarded simultaneously. The most researchers ever were rated by the NRF this year. After the constant turmoil of a few years ago, Kovsies has now become one of the most stable campuses in South Africa,” Prof Jansen says.

The impartial findings of a recent survey of UFS stakeholders showed that our values are endorsed by 92%; 86% agrees with our vision; 81% agree with our goals; 77% agree with our transformation; 78% believe that we are inclusive; and 78% applauded our overall reputation index. “These figures are very different from a few years ago when the university experienced a crisis,” he says.
 
According to Prof Jansen, the UFS’s financial situation is one of the most stable of all universities in South Africa, with a strong balance sheet and growing financial reserves – way better than before. This is exactly the reason why the UFS received confirmation from the Independent Regulatory Board of Auditors (IRBA) this year that we complied with international standards of reporting for the financial year which ended on 31 December 2013.

“I am also pleased to report that the crisis in the delivery of health services in the Free State province has been resolved due to collaboration between the UFS Management (including the Dean: Health Sciences and Head of the School of Medicine), the Department of Health and the Premier, Mr Ace Magashule. Although the loss of skilled personnel is still a concern, the Dean and Head of the School of Medicine are recreating the Health Services Platform at Universitas Hospital. However, the academic training of no undergraduate medical student or any student in the Health Sciences was influenced by the crisis in the Universitas and Pelonomi Hospitals”, he says.

The UFS is regarded around the world as a model of transformation and reconciliation in the student body. The recent SRC elections are only the most visible example of how far we have come in terms of leadership diversity. “Not a week goes by in which other universities, nationally and abroad, do not come to Kovsies to consult with us on how they can learn from us and deepen their own transformations, especially among students”, Prof Jansen says.

“The UFS will continue its model of inclusive transformation which provides opportunities for study and for employment for all South Africans, including international students and colleagues. We remain committed to our parallel-medium instruction in which Afrikaans remains a language of instruction; we are in fact the only medical school in the country that offers education and training in Afrikaans and not only English. We provide bursaries and overseas study opportunities to all our students, irrespective of race. And our ‘future professors’ programme is richly diverse as we seek the academic stars of the future. But we remain steadfast in our goal of making the UFS a top world university in its academic ambitions and its human commitments,” Prof Jansen says.
