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.

DF Malan – the politician, the man and Lindie Koorts’ award behind it

Sometimes fact is stranger than fiction. In this case, it is not only true, but fact is stirring up more of a buzz than make-belief does.

The first biography of an apartheid Prime Minister written since 1994, won an award at the 2014 Woordfees. ‘DF Malan and the Rise of Afrikaner Nationalism’ is the title of the book causing this national whirlwind. The author: Lindie Koorts – a postdoctoral fellow at the UFS’s Centre for Africa Studies.

She admits she was among the most surprised when she won the category for Debut Writers. “This is, as far as I know, the first time this prize goes to a non-fiction writer,” Koorts said.

What started as curiosity around DF Malan, four years later culminated in an objective biography devoid of justification or exoneration. “Throughout the process of writing, I offer the facts, but I do not clamber in with moralistic judgements,” Koorts said.

In addition to Malan the politician, Koorts discovered Malan the human being as well during her research. When she stumbled on his hand-written love letters to Maria Louw, which he wrote when he was in his 60s, a totally different man emerged. “I felt like a teenager while reading those letters!” Koorts laughed.

In the chapter entitled Coalition and Fusion, this dynamic historian unearthed a fact that had the power to change the course of history. Up until this point, the belief was held that one party deceived another. However, Koorts’ research proves that the entire issue rested on a letter that did not arrive on time. A case of tardy train schedules and a mere misunderstanding.

“To be able to unravel these things makes one feel that you have succeeded in something,” she said.

Not only did she succeed in writing an award-winning biography, she surely will be making history as she goes.
