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.

“It is quite easy to write a book in a professional capacity but very difficult to write a book from the heart.”

These were the words of Prof Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State (UFS), at the launch of Beauty of the Heart: The life and times of Charlotte Mannya Maxeke by Zubeida Jaffer, the current Writer-in-Residence in the Department of Communication Sciences at the UFS.

Perseverance and dedication yields results

Writing a book from the heart is exactly what Jaffer, an award-winning South African journalist and author, set out to do. “When you make the choice to write a story, you need to be very dedicated,” she said.

As this is Jaffer’s third book, one would think that she would have no difficulty in putting pen to paper. On the contrary, she mentioned that it was, in fact, the hardest book she has written because the narrative was not easy to get hold of.

“I wanted Charlotte’s voice to come through, and it took my team and I three years of research and writing,” she said.

Maxeke’s story helps to shape South African society

The three-person panel, hosted by the UFS Sasol Library and SUN MeDIA, and chaired by Prof Jansen, included Jaffer and Dr Thozama April, University of Fort Hare historian who had done her PHD thesis on Maxeke.

Dr April said that Maxeke’s life story is an inspiring one, as it encourages a rethinking of established narratives. “These established narratives have made it possible for historians and researchers to write about the shaping of South African society,” she said.
