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.

Leader of Bafokeng nation delivers a guest lecture at UFS

Kgosi Leruo Molotlegi, leader of the Royal Bafokeng nation, asked the pertinent questions: Who decides our fate as South Africans? Who owns our future? in the JN Boshoff Memorial Lecture at our university.

He said: “It’s striking that today, with all the additional freedoms and protections available to us, we have lost much of the pioneering spirit of our ancestors. In this era of democracy and capitalist growth (systems based on choice, accountability, and competition), we nevertheless invest government with extraordinary responsibility for our welfare, livelihoods, and even our happiness. We seem to feel that government should not only reconcile and regulate us, but also house us, school us, heal us, employ us, even feed us.

“And what government can’t do, the private sector will. Create more jobs, invest in social development and the environment, bring technical innovations to our society, make us part of the global village. But in forfeiting so much authority over our lives and our society to the public and private sectors, I believe we have given away something essential to our progress as people and a nation: the fundamental responsibility we bear for shaping our future according to aims, objectives, and standards determined by us.”

He shared the turnaround of the education system in the 45 schools in the 23 communities of the Bafokeng nation and the effect of greater community, NGOs, the church and other concerned parties’ engagement in the curricula and activities with the audience. School attendance improved from 80% to 90% in two years and the top learners in the matric maths in Northwest were from the Bafokeng nation. 

Kgosi Leruo Molotlegi stressed the need for people to help to make South Africa a better place: “As a country, we speak often of the need for leadership, the loss of principles, a decline in values. But too few of us are willing to accept the risk, the expense, the liability, and sometimes even the blame, that accompanies attempting to make things better. We are trying to address pressing issues we face as a community, in partnership with government, and with the tools and resources available to us as a traditionally governed community. It goes without saying that we can and should play a role in deciding our fate as members of this great country, and in the Royal Bafokeng Nation, as small as it is, we are determined to own our own future.”
