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.

Miss Deaf SA inspires UFS teachers with her life story
2009-11-26

Pictured from the left, are: K. Botshelo, Vickey Fourie (Miss Deaf SA) and A. Morake.

Vicki Fourie, Miss Deaf SA 2009 and Miss Deaf HESC, recently visited the University of the Free State to motivate aspiring Foundation Phase teachers by sharing her life story with them.

When Vicki was two years old, her parents found out that she couldn’t speak. Two possible explanations were that she had had an ear infection or speech problems. They took her to a specialist and after a brain scan they found out that Vicki had 97% hearing loss in both ears.

Hearing aids were required and Vicki’s father, Pastor Gerhard Fourie from the Christian Revival Church (CRC) enrolled her in a kindergarten school for deaf children, Carel Du Toit in Cape Town.

However, even though Carel Du Toit’s slogan is ‘Where Deaf Children Learn to Speak’, it was because of her mother’s efforts that Vicki is able to communicate effectively with hearing people today.

Bonita Fourie would sit with her child every single day and teach her how to pronounce words phonetically and how to read lips. It is because of that that Vicki is not dependent on sign language at all.

When she was seven years old, her parents enrolled her in an English A.C.E. school. Even though Vicki’s home language is Afrikaans, her parents decided to go against the norm by placing her in an English school (most deaf/hard of hearing people cannot learn a second language). Today Vicki is fluent in both languages.

“I used to think that my hearing aids are just a normal thing you put on, like using glasses for reading,” she said. “I still think that way. People always come up to me and say, ‘It’s amazing how easily you adapt to hearing people. You have no stumbling blocks or holdbacks.’

“To me it’s interesting because my reaction is always this: ‘God gave me this situation, and I have made the best of it. I’ve overcome it, and therefore I can go forward in life’. We were born not to survive, but to thrive. I detest the attitude of, ‘I’m a victim, so the world owes me something’. The world owes nobody anything! We can be victorious over our own circumstances. It is possible. My name’s meaning is testifies to this: “Vicki” comes from the word “Victory”. I was meant to be victorious, and not a victim.”

Vicki, who is now 20, has achieved so much in life. She did ballet, hip-hop, modern dancing, drama (she even went to America for her dramatic monologue and poetry recitation), and she has published over 70 magazine articles, nationally and internationally. Her dreams are to write books one day, become a TV presenter, and motivate and inspire people all over South Africa through public speaking.

When one hears this story, one cannot help but be surprised by her success. It makes you realize that anything is possible when you see the potential in a child, and then do everything in your power to develop it and draw it out. When you believe in the child that you are educating, that child will sense it and blossom like a flower.

“Courage isn’t a gift, it is a decision,” Vicki said. “There will always be things that try to hold you back. The key to working with any child is to be patient, patient, and patient! Teachers play a huge role in equipping children for the future. It is a big responsibility, but it can be done.”
