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.

University publishes its Integrated Report
2013-08-23

23 August 2013

The university is proud to have published an integrated report in line with the King III requirements on corporate governance. The university is one of the first universities – if not the first – in South Africa to do so. The UFS sees integrated reporting as a public process through which we report to all our stakeholders, using evidence-based data, on the achievements and challenges of a public university.

Our first Integrated Report reviews the overall performance, non-financial and financial, of the UFS for the 2012 academic year. It is the first report of its kind delivered to stakeholders and guided by the King III framework which recommends integrated, sustainable performance that is reported in a way that enables stakeholders to make an informed assessment of an institution.

The Integrated Report notes that the conditions under which higher education institutions operate have become more demanding in the last two decades and there is a growing need for universities to be more explicit and transparent about the manner in which their core functions (teaching, research and public duty), as well as its administrative operations, are defined by and support good governance, sustainability and corporate citizenship.

The university welcomes this opportunity to present in public an integrated account of itself. In particular, the UFS sees this report as an opportunity to align more strongly its financial and non-financial reporting in pursuit of organisational sustainability and social transformation in South Africa.

Prof Jonathan Jansen, Vice-Chancellor and Rector, notes in the report that in the past four years the university has made significant progress in respect of its two foundational commitments, the Academic Project and the Human Project.

There are now more students entering the university who satisfy the higher requirements set for admission. “This will improve the throughput and graduation rates of incoming students, ensuring their personal success and satisfaction with higher education.” The establishment of a state-of-the-art Postgraduate School, for example, is expected to increase the number, quality and success rates of postgraduate students.

The research output has increased steadily and the contribution of the new Senior Professors project, as well as the five research clusters, have helped to improve the quality of research and the spread of postgraduate recruitment beyond South Africa.

On transformation, the Vice-Chancellor observes that “We have made significant progress in building inclusive, democratic and embracing campus cultures which affirm the value and dignity of all students and staff. With the steady increase of black students in a majority black campus, our goal remains to retain our diversity in a university that serves as an experiment in teaching students to live and learn and love together.”

Financial sustainability is a major commitment and the UFS has not only maintained its record of unqualified audits, but has steadily built a culture of risk management and performance evaluation throughout the system. Internal auditing is a strong instrument in our arsenal to secure financial and operational compliance in every department of the university.

“What integrates the systems and functions of the university is the alignment of everything we do with our two pillars, the Academic and Human Projects, built on a solid foundation of professional support services as described in the Strategic Plan adopted in 2012. In the process of preparing the Integrated Report we discovered how much still needs to be done to align the still disparate and independent activities of the three campuses, seven faculties and more than 100 departments of this large university,” according to the Vice-Chancellor.
