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.

Valuable advice for businesses in difficult times

Dr Reuel Khoza, Chairman of the Nedbank Group, shared the group’s valuable rules for managing a bank in difficult times in an MBA lecture on the Bloemfontein Campus. Dr Khoza is a visiting professor at the UFS Business School.

He focused in the lecture on the group’s business and leadership model and highlighted some do’s and don’ts:

  • Do not surprise your stakeholders on the downside – communicate transparently, particularly when there is bad news.
  • Retrenching staff to contain costs should be a last resort – the damage to corporate culture from retrenchments is immense. Follow and support your customers – get as close to them as possible because business changes slowly, but customer behaviour can change in an instant.
  • Integrated central capital and funding management.
  • Entrench well-established reporting, KPIs and measurement systems.
  • Ensure strong independent risk management.
  • Manage your cost base – anticipate downturns and re-base your costs to avoid crisis-cost management.
  • Take advantage of opportunities – an economic downturn creates a situation where valuations fall and assets are sold off, which can be a great opportunity for acquisitions.
  • Keep innovating – innovation does not have to be a costly exercise, as the right culture can promote and encourage experimentation and collaboration.
  • Whatever you do – avoid a price war, as expedient pricing decisions may hurt the business in the longer term.
