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.

Heidedal-based foundation and UFS host inaugural music concert

Reach Our Community (ROC) Foundation in conjunction with the University of the Free State’s Odeion School of Music (OSM) held its first-ever music concert last month. Children who form part of the foundation’s Afterschool Care programme showed their impressive music skills to their parents and guardians in attendance.

ROC provides support to orphaned and vulnerable children from early childhood through to adolescence in the Heidedal community in Bloemfontein. The foundation strives to address the challenges resulting from factors such as poverty, unemployment, HIV/Aids, single parenting, lack of guardianship, and physical and sexual abuse. In the Afterschool Care programme, the children engage in educational, cultural, and recreational activities.

Going the extra mile

Since 2008, the UFS has successfully partnered with ROC through service learning and community engagement in which students from across all seven faculties participate. Two Music Education and Practice students from the OSM took it upon themselves to continue after their curriculum requirements were met.

Amy Viljoen- now a final-year BMus student, together with fellow student, Petre du Plessis, and their lecturer and programme coordinator, Gerda Pretorius, established the music class project in Heidedal in 2014. The students embarked on weekly trips to ROC, and would spend an hour working on the recorders and marimbas with children from ROC.

This year, Viljoen and Kara-Lynn Crankshaw, a final-year BA Music student, spent eleven months teaching the children music practice and theory, culminating in a concert that both the community and students can be proud of.

“I wanted to do something that was not only meant for educational purposes, but to give back to the community,” said Viljoen.

After having to gather extra chairs because of the influx of community members at the ROC hall, the founder, Patrick Kaars, said he had not expected such a turn-out. “It exceeded my expectations, and it was a dream come true. It meant so much to the children to be exposed to music, and to explore their own capabilities and talents.”

More children will learn how to play other instruments. Currently, the instruments used for the children’s training were purchased second-hand in order to cut costs. New music education specialists, who will join the programme in 2016, will also work with Pretorius to gather additional equipment, and compile learning material.

Kaars is also thrilled about the potential expansion to the music group, now that the concert has become an annual event. The OSM is also in the process of establishing a Centre for Music Development at ROC.
