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.

The first study book with the title Theology and the Post(Apartheid) Condition, which is part of a new academic series by the Faculty of Theology and Religion at the University of the Free State, is now available. Volume 1, compiled by Professor Rian Venter as editor, is the first book in the ‘UFS Theological Exploration’ academic series, which the faculty plans to release.

Transformation
Professor Venter says the transformation of processes and practices in communicating and creating knowledge has become an urgent task for public universities in a democratic South Africa. Much reflection has already gone into the methods and scope of transformation in higher education.

Although the faculty has done work on the implications of this for theology, there is one area of investigation that has not received much attention. It concerns the role of theological disciplines such as Old and New Testament, Missiology and Systematic Theology and Practical Theology, and specifically the relationship between academic disciplines and societal growth. The book focuses on these challenges and contains the intellectual undertakings of the contributors who are all lecturers, research fellows and post-graduate students linked to the faculty.

The questions
The key questions addressed are: what are the contours of the (post)apartheid condition and what are the implications for responsible discipline practices in theology. Professor Venter says the chapters in the book are logically arranged and moves from wider to more specific concerns. The first three chapters suggest broad perspectives on the challenges for theology in higher education, chart the changes, and make some suggestions for the future.

A dynamic field of study
The book states that theology has already experienced profound and radical changes over the past decade, which is known to us. All the chapters demonstrate these fundamental shifts, which have taken place in all theological sub-disciplines. Professor Venter says the contributions in the book illustrate that theology is a dynamic field of study, and is pursued with enthusiasm and commitment. Not all disciplines in theology are investigated for the book. However, the studies reflect the interests of the theologians in the Faculty of Theology at the UFS. Professor Venter hopes that the volume might stimulate further reflection of a similar nature by other theologians.

New insights
Through the ‘UFS Theological Exploration’ research series, the faculty hopes to stimulate new insights and new developments in academic progress and overall human growth. Series editor Professor Francois Tolmie says it is a fact that strong university research is necessary to achieve academic progress and advance human prospering. He says the faculty's research series will make a valuable contribution to these causes. Professor Tolmie says the ‘UFS Theological Explorations’ contains research of the highest academic standard which has been peer-reviewed to make significant educational contributions to core theological issues in South Africa and overseas.
