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.

UFS awaits applications for a full scholarship
2013-01-07

The office of the Vice-Chancellor and Rector of the University of the Free State, Prof. Jonathan Jansen,  offers a full scholarship to one learner  to study at the UFS in 2013.  

This scholarship will cover the tuition, residence, stationery and any specified course-related costs.  

All students who are passionate about  education and wish to contribute towards developing the South African education system, are encouraged to apply for this scholarship. The student may choose which education course he/ she would like to study and will be advised by our Dean of Education, Prof. Dennis Francis.  

The scholarship is a continuation of the Great Teachers Project headed by Prof. Jansen and research assistants, Nangamso Koza and Lihlumelo Toyana, who edited the book, Great South African Teachers.  

The editors have decided to donate the proceeds from the book towards the scholarship, and in partnership with our Faculty of Education, produce the country’s best teachers.  

This scholarship will also look at the holistic development of the learner, and thus award him/her with experiences of shadowing some of the country’s best educators, and take up internships in some of the country’s best schools in both the urban and developing communities.  

To apply, learners should provide their June and December gr. 12 results and also write an essay of 1 000 words titled: Educating a South African Citizen in the 20th Century.  

Applications must reach the UFS before 11 January 2013.
Please forward applications to: greatteachers@ufs.ac.za or fax to (051) 401 2705. Applications can also be mailed to: Office No. 26, Main Building, UFS, Nelson Mandela Drive, Bloemfontein 9301
