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.

Bloemfontein Campus hosts annual HELTASA conference

This year, the privilege to host the annual Higher Education Learning and Teaching Association of Southern Africa (HELTASA) conference was afforded to our university. The event took place on the Bloemfontein Campus from 18 – 21 November 2014, attracting keynote speakers and members from across the world.

HELTASA is a professional association mainly for educators and significant role players in higher education institutions. With its inception in the early 2000s, it has grown to become the premier organisation for teaching and learning in Southern Africa, Dr Amanda Hlengwa, President of HELTASA, pointed out.

A central concern of this body is issues around success within the tertiary sector. The theme of this year, ‘Accessing success: using evidence for change’ served to focus members’ attention on what works and what does not work – as derived from researched evidence.

In a message from Prof Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State (UFS), he stressed that the task as university teachers “is not simply cognitive gains that ensure graduation success but also intellectual gains that ensure success in life during and after university studies.”

The conference was led by internationally-acclaimed keynote speakers, namely Prof George Kuh, Prof William Grabe and Prof Fredricka Stoller, as well as our own A1 NRF-rated Prof Malanie Walker.

Prof Kuh is Adjunct Research Professor of Education Policy at the University of Illinois and Chancellor’s Professor of Higher Education Emeritus at Indiana University. In his keynote address, Prof Kuh offered valuable lessons from the field to promote student success.

Profs Grabe and Stoller collectively presented the second keynote address that explored how to set up students for success through strategic-reader training. Prof Grabe is Regents’ Professor of Applied Linguistics and Vice President for Research at Northern Arizona University. Prof Stoller is a Professor of English at Northern Arizona University, where she teaches in the MA-TESL and PhD in Applied Linguistics programmes.

Prof Walker is a Senior Research Professor at the UFS Centre for Research on Higher Education and Development (CRHED). She is also currently Director of Research Training and a senior researcher in the EU-funded Marie Curie EDUWEL project. In her keynote address, Prof Walker looked at well-being and agency in higher education.
