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.

Letter to students from Prof Jonathan Jansen about student protest action at the UFS
2015-10-21

Dear Students

Student protest action at the University of the Free State

I wish to make clear that the senior leadership of the University of the Free State understands and supports the demands from students and their leaders that higher education be accessible to all students, especially the poor. For the past six years we have done everything in our power to meet that commitment to students who are academically talented, but simply cannot afford to pay; that is why our tuition fees remain among the lowest in the country. Our efforts to raise private funding have enabled thousands more students to study at the UFS than would have been possible on the government subsidy only. Whether it is the Staff Fund contributions (yes, our staff empty their pockets to support student fees) or the No Student Hungry (NSH) bursary programme (yes, we raise funds for food bursaries), we will continue our drive to fund students who cannot afford higher education. Let me repeat, no student with a solid academic record will be denied access to studies simply because they cannot pay.

Now, to the matter at hand. There is a national demand from students for a 0% fee increment for 2016. The Minister’s response, after consultation with stakeholders, was that universities should cap their 2016 fee increases at 6%. Despite this initiative from government, the protests continue on virtually all campuses across South Africa for the ‘no fee’ increase.

Our response, as the UFS leadership, is to continue engaging the SRC as the chosen leadership of our students in trying to negotiate a settlement on the matter. We have worked around the clock to be available to student leaders to find some resolution on 2016 fees. While we understand the demands of students, as university leaders, we can only work with the government subsidy we receive. Any agreement reached, cannot and must not place the university at academic and financial risk in its ability to deliver public higher education to the country - if that happens, everybody loses. Still, no matter what happens in terms of the response from government, the leadership door at the UFS remains open to finding a mutually acceptable solution to all parties in these deliberations.

Students, we are deeply concerned by the violence, intimidation and threats from the small group of protesting students. These dangerous and demeaning behaviours, like disrupting classes and verbally abusing students and staff, undermine the legitimate quest of students for relief concerning tuition fees. Such behaviour is completely unacceptable and the university will take action where required. We must also remember that we have an obligation to all 30 000 students whose right to learn without fear of violence and intimidation must be respected.

In conclusion, over the past few years we have worked hard to build a culture of mutual respect and embrace as we worked through some very difficult challenges on campus. You would have noticed that the university leadership responded quickly and sympathetically to reason and respect in difficult situations of rage and demonstration. A minority of students, with some outsiders, have come onto the campus to break down that culture in which, while we might disagree, we continue to work on the basis of mutual respect. I urge all students that, as we engage of this important problem of enabling greater access to higher education, we continue to remain true to the core values of our Human Project.

Best Regards

Prof Jonathan Jansen
