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.

New security measures for Rag fundraising
2012-01-25

The University of the Free State will no longer allow first-year students to sell Ritsems or to shake their cans for change at traffic robots in Bloemfontein in an effort to raise funds for Rag Community Service.

This decision follows after an evaluation has been done in 2011 and 2012 concerning the safety risk for students during this type of sales at road crossings.
 
The new security measures have specifically been implemented for this type of sales since last year.
 
The measures included, among others, that students should be obliged to wear brightly coloured safety jackets during sales, continuous supervision of first-year students by senior students to ensure that students keep to the rules of the road, and limiting the sales hours at robots.
 
Through notices in the media, an appeal was made on motorists to keep a lookout for students raising money for Rag Community Service. The measures were implemented and the effects thereof for students’ safety during sales at robots monitored since last year. This follows after a student, Ms Hanje Pistorius, was hit by a reckless driver in 2010 and she subsequently lost her leg as a result of the accident. 
 
Although, from all appearances, the new measures are a positive contribution to protect students even more, the UFS decided to abolish the sales and fund-raising actions at traffic robots. As reckless drivers would not necessarily take notice of the extra measures, the risk to students at robots stay unchanged. 
 
"The UFS sets the safety of its students as first priority and considers it in the best interest of students to not expose first-years to the risk during our Rag programme,” says Mr Rudi Buys, Dean: Student Affairs at the UFS.
 
Night fund-raising and the selling of Ritsem in the city’s suburbs will, however, continue. 
 
Although the UFS do not expect the new measures to be detrimental to fund-raising efforts, Rag Community Service currently considers new supporting proposals for the raising of funds for community projects in order to address any possible reduction in funds. 
 
Mr Buys also has an agreement with Ms Pistorius to assist Rag Community Services in the planning of new projects.
 
The Night fund-raising in suburbs will take place on Tuesday 24 January and Thursday 26 January and the UFS calls on residents to assist students and help them in the important task at hand.
 
Three Rag processions will take place on Saturday 28 January 2012. At 10:00 two Rag procession will be leave for Heidedal and Mangaung, where the Kovsie Rag Community Service will hand out food parcels.
 
The main Rag Procession will leave the UFS at 18:00 and will move towards the Old Greys sports ground for the Rag concert with Die Heuwels Fantasties and DJ Black Coffee.
