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.

Zubeida Jaffer short film to feature on SABC3

The nation-building initiative known as 21 ICONS South Africa, was recently thrilled to announce that Zubeida Jaffer will feature in their second season due to her professional excellence as a journalist and author.

Jaffer is a well-known South African reporter and author and has been a writer-in-residence at the UFS for three years now. The 21 ICONS project was inspired by Nelson Mandela and has created a movement for positive change. By sharing the stories of iconic South African men and women, the intention is to inspire new generations to follow in their footsteps.

One icon is featured per week in a visual celebration of engaging and entertaining portraits and short films, along with an essay biography across multiple media platforms such as print, broadcast, outdoor and social media. Jaffer’s short film will be broadcasted on 2 November 2014 at 20:27 on SABC3 and her collectable portrait will be published in City Press on the same day.

Jaffer’s short film discusses her truth as a journalist and activist who was a key figure in the struggle movement in the Western Cape during apartheid. In an intimate conversation with Adrian Steirn (creator, photographer and director of 21 ICONS, Jaffer talks about her journey as a journalist who always seeks to uncover the truth and give people who don’t have a voice an outlet to express their views, opinions and thoughts.

Other iconic South Africans that have featured on 21 ICONS, were among others, Francois Pienaar (former Springbok rugby captain who won the 1995 Rugby World Cup), Pieter-Dirk Uys (satirist who used comedy and caricature to oppose the apartheid government) and Frene Ginwala (the first female speaker in the National Assembly of South Africa).

With the country celebrating 20 years of democracy, the message that everyone can do something to make a difference – which is portrayed in these powerful and inspiring stories that make up the second season of 21 ICONS – has been well-received by South Africans.

Be sure to get your City Press early and tune in on the evening of 2 November 2014 to see Jaffer’s feature on 21 ICONS.

Jaffer is also the publisher of the Journalist website (http://www.thejournalist.org.za/) launched earlier in 2014, of which the UFS is the founding member. The Journalist is “an independent, non-profit organisation working with the academic community and a range of credible online entities to make their knowledge more accessible to the wider public.”
