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.

SRC visits the US as part of Global Leadership Preparation Programme
2012-06-07

The Student Representative Councils (SRC) of the University of the Free State’s (UFS) Bloemfontein and Qwaqwa Campuses will be travelling to the United States from 10-24 June 2012 on an intensive leadership development programme.

The Global Leadership Preparation Programme, initiated by the Vice-Chancellor and Rector, Prof. Jonathan Jansen, has been designed to ensure that South Africa’s next generation of leaders understand their unique place in a global context, the interconnectedness of global and local society and various possibilities for change.
 
The group of 36 students will be visiting Washington DC, Boston and New York.
 
“As a university we recognise that students who lead on campus must be prepared to also lead the country, which requires amongst others greater understanding of the impact and influence of global developments (social, economic, political) on nation states and campuses. This includes knowledge to deepen democratic participation and real representation – issues we know that often are contested in important student governance structures such as SRCs,” says Mr Rudi Buys, Dean of Student Affairs.
 
The group will be studying among others the impact, influence and limits of the United Nations in global leadership; the impact of transnational companies on economic policies of African countries; the impact of American universities on African leadership; the impact of international philanthropy on African development and the impact of American public institutions on learning among the disadvantaged: lessons for South Africa.
 
The programme complements and strengthens other leadership preparation programmes of the UFS, such as the Leadership for Change Programme and the Gateway College Programme – an intensive orientation programme for all undergraduate students. It will give students a competitive advantage in leadership over more local programmes and initiatives that seldom look beyond the campus, or even beyond the country, in preparing the next generation of leadership.
 
“We value this initiative by the university leadership to give us the opportunity to explore and spread our wings and gather as much knowledge as we can get to raise the bar in terms of student governance and leadership. The university is amongst the few in the country that sees the need to strengthen and develop its student leadership by exposing it and allowing it to understand its role in a global context. This is a chance that we take seriously and we intend to use it to the betterment of the institution,” says Bongani Ngcanga, President of the Central SRC.
 
“While we welcomed the initiative taken by the university to design this programme, the SRC questioned and debated heavily on the merits and real contribution of such a programme. Only on approval of the academic and development profile of the programme did we accept its merits and now are excited about the value thereof. This opportunity goes beyond the term of the SRC and will develop and equip us for the great positions we will hold in the future. I am looking forward to meeting influential lobbyists, profound academics and strong politicians,” says Richard Chemaly, SRC President of the Bloemfontein Campus.
 
Upon their return, the SRCs will set a new benchmark for future councils, raising the bar to that of internationally acclaimed student leadership. One of the objectives of the programme is to produce written, reflective statements about the learning that resulted from the trip and to start dialogues in order to improve student governance and governance as a whole. Workshops will also be presented for aspirant student leaders on leadership lessons learnt from an international perspective.
 
Members of the SRCs are covering part in the cost of the programme and generous contributions have also been received from outside the university.
