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.

UFS awards honorary doctorate to Archbishop Emeritus Desmond Tutu
2011-01-01

Archbishop Emeritus Desmond Tutu

The University of the Free State (UFS) will reach a milestone in its history today when an honorary degree, the Doctor of Theology, will be conferred on Archbishop Emeritus Desmond Tutu.

At the same event Archbishop Tutu will launch the university’s International Institute for Studies in Race, Reconciliation and Social Justice.
 
The idea of the establishment of such an institute originated after the Reitz incident in 2008. In 2009, during his official inauguration, Prof. Jonathan Jansen, Vice-Chancellor and Rector, embodied this idea when he stated that the university would be an example of a place where reconciliation, forgiveness and social justice would not only be studied, but where it would also be applied in practice. “Students and scholars from across the world will come to the UFS to study the theory and practice about the building of societies across the boundaries of race, as well as religion, gender, disabilities and national origin,” Prof. Jansen said.
 
The institute is a critical intellectual space where engaged scholarship, public discussion, community engagement and contextually relevant teaching are innovatively harnessed towards exploring and finding solutions to the complex and challenging work of social transformation in South Africa,” says Mr John Samuel, Interim Director of the institute. Mr Samuel was the former Chief Executive Officer of the Nelson Mandela Foundation.
 
According to Mr Samuel, the institute seeks to establish itself as a premier international site for research on race, reconciliation and social justice. “We want to link the manifestations of race in higher education, to the related matters of reconciliation and social justice in the South African context against the backdrop of racial and ethnic conflicts elsewhere in the world,” says Mr Samuel.
 
The institute will, amongst others, publish groundbreaking research, organise national and international conferences about reconciliation and social justice, as well as contribute to the establishment of national and international networks that are actively involved in matters relating to race, reconciliation and social justice. Through its research, the institute will endeavour to understand the challenges facing the UFS better, as well as how to address these challenges. For this reason, the concept of the UFS as a “live laboratory” and the use of evidence-based practice remain important for the university.
 
By honouring Dr Tutu, the UFS recognises the contribution that Dr Tutu has made in the field of Theology through his teachings and the books he has written. However, the UFS is not only honouring him as a moral and religious leader who has maintained his integrity as a Christian. “We honour a great son of South Africa who has made a huge contribution to peace, reconciliation and justice in South Africa and in the world,” says Prof. Jansen.
 
The unveiling of the new corporative brand of the UFS will render further lustre to the day.
