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.

The failure of the law

- Call for the protection of consumers’ and tax payers rights against corporate companies

An expert in commercial law has called for reforms to the Companies Act to protect the rights of consumers and investors.

“Consumers and tax payers are lulled into thinking the law protects them when it definitely does not,” said Prof Dines Gihwala this week during his inaugural lecture at the University of the Free State’s (UFS).

Prof Gihwala, vice-chairperson of the UFS Council, was inaugurated as extraordinary professor in commercial law at the UFS’s Faculty of Law.

He said that consumers, tax payers and shareholders think they can look to the law for an effective curb on the enormous power for ill that big business wields.

“Once the public is involved, the activities of big business must be controlled and regulated. It is the responsibility of the law to oversee and supervise such control and regulation,” said Prof Gihwala.

He said that, when undesirable consequences occur despite laws enacted specifically to prevent such results, it must be fair to suggest that the law has failed.

“The actual perpetrators of the undesirable behaviour seldom pay for it in any sense, not even when criminal conduct is involved. If directors of companies are criminally charged and convicted, the penalty is invariably a fine imposed on the company. So, ironically, it is the money of tax payers that is spent on investigating criminal conduct, formulating charges and ultimately prosecuting the culprits involved in corporate malpractice,” said Prof Gihwala.

According to Prof Gihwala the law continuously fails to hold companies meaningfully accountable to good and honest business values.

“Insider trading is a crime and, although legislation was introduced in 1998 to curb it, not a single successful criminal prosecution has taken place. While the law appears to be offering the public protection against unacceptable business behaviour, it does no such thing – the law cannot act as a deterrent if it is inadequate or not being enforced,” he said.

The government believed it was important to facilitate access to the country’s economic resources by those who had been denied it in the past. The Broad Based Economic Empowerment Act of 2003 (BBEE), is legislation to do just that. “We should be asking ourselves whether it is really possible for an individual, handicapped by the inequities of the past, to compete in the real business world even though the BBEE Act is now part of the law?,” said Prof Gihwala.

Prof Gihwala said that judges prefer to follow precedent instead of taking bold initiative. “Following precedent is safe at a personal level. To do so will elicit no outcry of disapproval and one’s professional reputation is protected. The law needs to evolve and it is the responsibility of the judiciary to see that it happens in an orderly fashion. Courts often take the easy way out, and when the opportunity to be bold and creative presents itself, it is ignored,” he said.

“Perhaps we are expecting too much from the courts. If changes are to be made to the level of protection to the investing public by the law, Parliament must play its proper role. It is desirable for Parliament to be proactive. Those tasked with the responsibility of rewriting our Companies Act should be bold and imaginative. They should remove once and for all those parts of our common law which frustrate the ideals of our Constitution, and in particular those which conflict with the principles of the BBEE Act,” said Prof Gihwala.

According to Prof Gihwala, the following reforms are necessary:

• establishing a unit that is part of the office of the Registrar of Companies to bolster a whole inspectorate in regard to companies’ affairs;
• companies who are liable to pay a fine or fines, should have the right to take action to recover that fine from those responsible for the conduct;
• and serious transgression of the law should allow for imprisonment only – there should be no room for the payment of fines.
 

Prof Gihwala ended the lecture by saying: “If the opportunity to re-work the Companies Act is not grabbed with both hands, we will witness yet another failure in the law. Even more people will come to believe that the law is stupid and that it has made fools of them. And that would be the worst possible news in our developing democracy, where we are struggling to ensure that the Rule of Law prevails and that every one of us has respect for the law”.
