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.

UFS to accredit providers of Off-Campus Accommodation to students in Bloemfontein
2017-06-30

The University of the Free State (UFS) has embarked on a process to accredit off-campus accommodation service providers in Bloemfontein who provide accommodation to its students.

“The decision to accredit off-campus accommodation service providers comes from a concern from the university management about the safety of students and the conditions under which some of our students live in off-campus accommodation. Student accommodation is a significant aspect of the success of the UFS and consequently good quality accommodation is important for each individual student to be successful in his/her studies,” says Mr Quintin Koetaan, Senior Director: Housing and Residence Affairs at the UFS.

The accreditation process entails a list of primary requirements, drafted with the cognisance of the Mangaung Metropolitan Municipality, in terms of off-campus accommodation to which private providers must adhere in order to be accredited by the university. The requirements are in line with the Policy on the Minimum Norms and Standards for Student Housing at Public Universities (Government Gazette 39238, dated 29 September 2015).

According to Koetaan, the norms and standards as set out in the policy establish the foundation and assessment criteria for such accreditation of service providers by the UFS. “It has become necessary for the UFS to have a policy on off-campus accommodation, in order to protect the rights and interests of our students and that of the university,” says Koetaan.

Some of the primary requirements for accreditation by the UFS include the number of students that may be accommodated in each room, the quality of kitchens and kitchenettes, the number of ablution facilities, the existence of common rooms and house rules, general maintenance and cleaning, compliance with  relevant national, regional, and municipal legislative requirements regulating health and safety, provision for adequate access to the facility/establishment in case of medical and/or psychological emergency assistance being required by students, and the provision for access to emergency electricity and water facilities. Off-campus private accommodation service providers must also be in possession of approved Municipal building plans of their student accommodation facilities, as well as evidence confirming their compliance with these plans.

“Landlords and agents are also advised to become more involved in their student homes and to ensure that their properties are in good condition and secure enough for students to live in,” says Koetaan.

Off-campus private accommodation service providers have until 31 July 2017 to apply for accreditation. More information and application documentation for accreditation can be obtained by sending an email to housing@ufs.ac.za
