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.

“A graduation ceremony epitomises every student’s academic dream and pursuit, and allows you to look back as you enter the professional career of your choice.”

These were the words of guest speaker Dr Mafu Rakometsi, Chief Executive Officer of Umalusi, that resonated through the Callie Human Centre at this year’s Summer Graduation on the Bloemfontein Campus. He mentioned that today graduates would look back at a journey that started with hesitant steps, and despite all their ups and downs, they had managed to make it this far.

During the afternoon session, Prof Lis Lange, Vice-Rector: Academic, at the University of the Free State (UFS), said that graduations were always an occasion for celebration and this year, there were two reasons for these celebrations.

 “The first is simply that we made it through a difficult 2016 and the secondly because we are celebrating two crucial professions that will attribute to the well-being of this country, namely teachers and health practitioners.”

Meaningful graduation ceremony for Ferial Haffajee

This year, the UFS had the privilege and honour to confer editor-at-large at The Huffington Post SA, Ferial Haffajee, with an honorary doctorate in the Faculty of the Humanities.

Speaking after the graduation ceremony, Dr Haffajee said, “It was really, really meaningful for me, because I’ve never been able to graduate. When I finished university, it was during the struggle against apartheid, so we didn’t graduate. It was a wonderful day and wonderful to see the role that young people are playing on this campus.”

“Dr Ferial Haffajee has made a significant contribution to press freedom in South Africa. She is known both nationally and internationally for the work she has done and therefore it is an honour to welcome her as a Kovsie. She is one of the people who represent the values of the UFS. We are proud of her and we wish her great success,” said Prof Milagros Rivera, Head: Department of Communication Science and acting Dean of the Faculty of the Humanities at the UFS.

Inspiration drawn from graduation ceremonies

During his address, Dr Khotso Mokhele, the Chancellor of the UFS, made special mention of many that inspired him at the graduation ceremonies.

His inspirations included Dr Ambrotius Swartbooi, who suffered a spinal injury from a near-fatal car accident which left him paralysed and a quadriplegic, yet who still managed to receive his doctorate; Setsoane Ntseki, a matriculant with poise and an incredible voice, who delivered the song item; Judge Ian van der Merwe, Chairperson of the Council at the UFS and a close friend of Dr Mokhele, with whom he worked for many years; as well Dr Haffajee, a trail-blazer that many look up to.

Damian Viviers was recognised as one of the youngest PhD graduates in the Faculty of Law, where he received a PhD in Mercantile Law. He is a research fellow in the Department of Mercantile Law, and was recently appointed as candidate attorney in the commercial department at Phatshoane Henney Attorneys.

In closing, his message to the class of 2016 was simple, that even though the world and our country may find itself in an odd space now, the graduates needed to remember that even though they would become leaders, there was always something bigger than themselves.

“Go out there and do us proud. Come back and plough back into this institution not only with your money, but your skills and time too.”
