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.

2010 World Cup: An opportunity for nation-building

“The 2010 FIFA World Cup creates a window of opportunity for nation-building in South Africa that could even surpass the opportunity created by the 1995 Rugby World Cup.”

This was according to Prof. Pieter Labuschagne from the University of South Africa, who was one of the three speakers during the lecture series on soccer that were recently presented by the Faculty of the Humanities at the University of the Free State (UFS), in conjunction with the German Academic Exchange Service (DAAD), under the theme: Soccer and Nation Building.

Prof. Labuschagne delivered a paper on the topic, The 2010 Soccer World Cup in South Africa: Nation Building or White Apathy?, highlighting the critical issue of how sport in South Africa was still largely supported along racial lines.

“We are still enforcing the separateness of rugby as a sport for whites and soccer as a sport for blacks,” he said.

He said a high degree of animosity against soccer existed among whites because they felt rugby and cricket were being singled out by parliament as far as transformation was concerned. He said that could be the reason why a large number of South African whites still supported soccer teams from foreign countries instead of local Premier Soccer League teams.

“Bridging social context between different racial groups is still a major problem, even though patriotism is comparatively high in South Africa,” added Prof. Norbert Kersting from the University of Stellenbosch, who also presented a paper on World Cup 2010 and nation building from Germany to South Africa, drawing critical comparisons on issues of national pride and identity between the 2006 World Cup in Germany and the 2010 World Cup.

“Strong leadership is needed to utilize the opportunity provided by the 2010 World Cup to build national unity as former President Nelson Mandela did with the Rugby World Cup in 1995,” said Prof. Labuschagne.

Although acknowledging the power of sport as a unifying force, Prof. Scarlett Cornelissen, also from the University of Stellenbosch, said that, since 1995, the captivating power of sport had been used to achieve political aims and that the 2010 World Cup was no different.

Amongst the reasons she advanced for her argument were that the 2010 World Cup was meant to show the world that South Africa was a capable country; that the World Cup was meant to solidify South Africa’s “African Agenda” – the African Renaissance - and also to extend the idea of the Rainbow Nation; consolidate democracy; contribute to socio-economic development and legitimize the state.

“We should not place too much emphasis on the 2010 World Cup as a nation-building instrument,” she concluded.

She presented a paper on the topic Transforming the Nation? The political legacies of the 2010 FIFA World Cup.

The aim of the lecture series was to inspire public debate on the social and cultural dimensions of soccer.
