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.

Institute for Reconciliation and Social Justice: cultivating humanity
2014-12-15

Directors of university centres focusing on Social Justice, Diversity and Transformation met at the UFS to establish the Directors' Forum. The forum discussed the state of higher education transformation in South Africa  The forum consists of (from the left) Mr Allan Zinn from the The Centre for the Advancement of Non-racialism and Democracy at the Nelson Mandela Metropolitan University, Profs Melissa Steyn from Wits University's Centre for Diversity Studies,  Andre Keet Director of the The Institute for Reconciliation and Social Justice at the University of the Free State; Rozena Maart  from The Centre for Critical Research on Race and Identity  at the University of KwaZulu Natal and Mr JC van der Merwe, researcher at the UFS Institute for Reconciliation and Social Justice

The Institute for Reconciliation and Social Justice at the University of the Free State (UFS) provides a critical space that brings different voices, ideas and practices together to advance the Human and Academic Projects of the university. Students, staff and community members meet here to find ways to engage with diverse views, realities and aspirations.

“We cultivate humanity so that reconciliation and social justice can be expressed in our everyday life and we work against disrespect and inequalities on our campuses and in our society,” says Prof André Keet, Director of the Institute for Reconciliation and Social Justice.

“Through our various critical conversations, public lectures, seminars and colloquia, fresh understandings and ideas come to the fore and new inclusive ways of doing life in a local and global multicultural society are invented,” Prof Keet says. A host of international experts formed part of the institute’s events during 2014.

Dr Charles Alexander (University of California), Prof Halleh Ghorashi (Vrije Universiteit Amsterdam), Prof Alex Hinton (Rutgers University), Dr Shirley Anne Tate (University of Leeds) and Prof Susan Spearey (Brock University) were but a few of the international experts contributing to the work of the institute during the last year.

“We play key roles in transformation debates within Higher Education South Africa (HESA) and ministerial processes,” Prof Keet says. “We promote, protect and monitor human rights across our campuses and are frequently requested to support the work of the South African Human Rights Commission and to provide advice to other state agencies.”

The institute prides itself on their leading-edge research on social cohesion, reconciliation, human rights and higher education transformation. In addition, staff of the institute teaches, on invitation, at various faculties, as well as at other national and international universities.

To further bolster their impact, the institute is launching three master’s and doctoral postgraduate programmes in January 2015.
