Dr Alba du Toit, Senior Lecturer in the Department of Sustainable Food Systems and Development, is leading the newly established Innovative ARC-DALLRD-UFS Agro-processing for Climate-smart Food System research chair at the UFS.

The Innovative Agro-processing for Climate-smart Food System research chair, one of four ARC-DALLRD-UFS research chairs recently established at the University of the Free State (UFS), will focus on innovative agro-processing technologies that could affect food and nutrition security. The chair’s work will also focus on improving food systems that can impact socioeconomic development.

In a concerted effort to address the challenges and effects of climate change in Southern Africa, the UFS, together with the Agricultural Research Council (ARC) and the Department of Agriculture, Land Reform and Rural Development (DALRRD), established four new research chairs within the Faculty of Natural and Agricultural Sciences (NAS).

The other research chairs are Climate Change and Agriculture, Agriculture Risk Financing and Sustainable Livestock Production and together with the Innovative Agro-processing for Climate-smart Food System research chair, and fall under the umbrella of climate change. They will also be part of the centre of excellence of the ARC and DALRRD on Climate Smart Agriculture.

Dr Alba du Toit, Senior Lecturer in the Department of Sustainable Food Systems and Development, will lead the Innovative Agro-processing for Climate-smart Food System research chair and says the chair allows researchers to dedicate their time and effort towards research. It consolidates expertise, resources, and facilities to strengthen the research team’s capacity and will have a strong foundation for sustainable development goals. The chair provides a hub for collaboration between the UFS, ARC and DALLRD to focus on regionally engaged research with maximum societal impact.

The chair, which officially started on 1 July, also allows researchers to do trans- and multi-disciplinary, relevant and cutting-edge research.

Nixtamalisation could transform the food system

“We believe that nixtamalisation could transform the food system. However, the consumer’s willingness to adopt and embrace new products and techniques is dependent on the success of the initiative.

“Thus, innovations in new product development must be consumer-led since the consumer is constantly evolving, making it imperative to understand consumer behaviour and motivations behind decision-making,” says Dr Du Toit.

The nixtamalisation process, she explains, is a multistep technique commonly employed in Mexico, Central America and the southern regions of the US to transform maize into food products. The nixtamalisation process alters the physicochemical, nutritional and sensory properties of maize products by increasing protein quality, improving the content of calcium, magnesium and potassium and reducing mycotoxin levels.”

According to Dr Du Toit, by using the principles of circular food design, they will develop products that could provide solutions and support the food system. It involves using processing technologies that could be applied and implemented by anyone with access to a basic kitchen.

“This would benefit rural farmers and communities, small-scale and emerging farmers to provide food for themselves and become economically active small business owners. We believed the right product could not only influence the food security and well-being of individual households but also stimulate entrepreneurial action, which could benefit the community and overcome barriers to make nixtamalisation an acceptable practice for all,” says Dr Du Toit.

Maize and sorghum

“Maize and sorghum are staple crops in South Africa that are not being utilised to their full potential. South Africa is well known for its maize production, and it is the staple for most of the population in the form of pap. However, the reliance on pap exaggerates the issues of food and nutrition insecurity because pap cooked from Super Maize Meal is deficient in nutrients and often consumed in isolation without diversification in the diet.

“Sorghum is another cereal crop that is climate-smart, drought-resistant and suited in South Africa’s arid and semi-arid areas, while it offers good nutritional value. However, most consumers are not familiar with the crop except for its application as an instant porridge.  Nixtamalisation is a process that could benefit consumers as maize and sorghum could be transformed into nutritious, safe meals directly from the farm to the fork,” explains Dr Du Toit.

Home-grown dried whole maize kernels, she continues, could be converted into safe and delicious meals in homes using basic equipment as it is widely and effectively done in Mexico by rural women. The research will determine if consumers would accept the process of nixtamalisation, whether the products would be acceptable, and if the nutritional value would be comparable to commercial products.

Some of the news consumer-acceptable products already developed, include maize chips, dehydrated phutu pap, and corndogs. Currently, the team is working on maize-milk, maize-milk frozen dessert and a custard tart. Maize products have the advantage of being lactose- and gluten-free and thus would appeal to consumers of plant-based products.

Societal impact

Dr Du Toit says she is excited about the societal impact this project will have on communities and the country and is hopeful that they will be able to influence policymakers and the industry to provide more nutritious staples that could be “game-changers” for the sake of society. She is looking forward to collaborating with DALRRD, the ARC and the grain industry to ensure that partnerships are strengthened and new opportunities are created for the staff and students.

Prof Wilna Oldewage-Theron, a Professor of Nutrition in the College of Human Sciences at Texas Tech University, will join the research chair next year as the co-leader. She has experience in community nutrition research in Africa, and her research interests include the factors contributing to household food insecurity and malnutrition in resource-poor communities. She will be focused on the nutritional benefits of soy for human health.

Prof Maryke Labuschagne, who is leading the NRF SARChI Chair in Diseases and Quality of Field Crops and who is passionate about impacting malnutrition, has been appointed as mentor for the chair.

Prof Jonathan Jansen bids farewell to Kovsies
2016-08-31

 

Dear Kovsie staff and students

This is my final message to you all.

I wish to use this opportunity for some brief reflections, share a word of gratitude, and convey a sense of the future for our beloved university.

Since the announcement of my departure, I have had more than a dozen breakfasts with mainly students, but also staff, to offer an opportunity for the final sharing of thoughts and, of course, goodbyes. The most common questions asked at those breakfast sessions were the following, with my responses. I repeat them here, since these might also be of interest or concern to you.

What are your proudest achievements?
Two things. The increase in the academic standard for the UFS, both in terms of admission standards and pass rates, but also in relation to the requirements for appointment and promotion especially of professors. This is important because in a globally competitive world, a university stands or falls by the quality of its degrees. And for this you need the best students and the best professors.

What would you do differently, given another chance?
Nothing. I believe that leadership is about doing the best you can with the cards you are dealt in the circumstances in which you are placed. There is no point in second-guessing past decisions. I have always been ambitious as a leader, knowing that most of my goals would be met, and that some would not. That is normal in large and complex organisations, and so, I do not sit around pondering regrets, only remembering with gratitude the things we could achieve together.

What did you learn?
A lot. I learnt that our students have tremendous capacity for greatness both in their academic pursuits but also in their ability to live, and learn, and love together. I have learnt never to underestimate the capacity of our youth to excel in whatever they do. Sometimes I felt I was more ambitious for our students and staff, than they were for themselves. But I have constantly been surprised by the capacity of young students to rise above bitterness and division, and to make great our campus, country, and continent.

I learnt, again, that the overwhelming majority of our staff and students are good people, respectful of each other, and determined to work together to heal our broken past and build a more just society. And I learnt that it is much more fulfilling to build up than to break down, to embrace than to exclude, and to love than to hate.

Were you frustrated with the pace of transformation?
Sometimes, yes. But fortunately I studied educational organisations all my life, mainly schools and universities. Universities are called institutions for a reason, and on century-old sites like the historic Bloemfontein Campus of the University of the Free State, there are core beliefs, values, and practices deeply ingrained in the culture of the place.

Anyone, therefore, who believes that transformation is easy, has obviously never tried to change an old university. It is difficult. You will get blowback. You will get bad press. You will, sadly, lose the support of some people. Some believe the university is changing too fast while others will tell you it is not changing fast enough. As you press for change, you find the university going two steps forward and one step back; in these circumstances, the solemn duty of the leader is simply to ensure that the overall momentum is always forward.

I therefore budget for disappointment even as I relish the many changes we have experienced together over the past seven years. If you want to obtain an objective sense of the scale of the changes at the UFS, ask those students and staff who were here in 2009, not those who came recently. They will tell you that we have a very different university, even though we all acknowledge that there is still some distance to travel. Our remarkable story of change is told in the recent Transformation Audit of the UFS, chaired by Prof Barney Pityana; that Audit Report will be released after it is read and studied by the University Council at its November meeting.

At an individual level, I learnt that most campus citizens change quickly and others more slowly, and that one has a duty to constantly push for change, but also to be patient about change. And I learnt that the ideal change retains the best of our past even as we embrace a more just and inclusive future in which all campus citizens feel that the university truly belongs to each and every one of them.

Are you optimistic about the future of our university?

Yes. The UFS is a very well-managed university thanks to the exceptional talent in the management of our finances, human resources and information technology environments. By the end of 2016, we will have record enrolments, from undergraduates to doctoral students, which is good for our future income. We run a tight ship with regard to the university’s finances, and we have greatly improved the academic standard of our qualifications; in this regard, I am very proud of my senior management team, and the talented middle management personnel, and those who make things work at the coalface of our operations.

I am very concerned, however, about future funding of the 26 public universities and the extremely vulnerable situation of at least 10 higher-education institutions. The economy is not growing and the costs of running a modern university are escalating. The delays in government commission reports on tuition fees do not help, and there seems no urgency ‘higher up’ to make the tough decisions.

We have to ensure free education for the poorest students — that is the position of your senior management – but we also need to guarantee the financial sustainability of our universities. The task of the UFS leadership, in this period of uncertainty, is to manage those two expectations as best we can. But this cannot happen without your assistance, and I do ask that you provide the new Rector and his or her team with the same understanding and support which I have enjoyed from you.

In conclusion
I am grateful.

To the many hundreds of students who have passed through my office and our home, and who sat in my many lectures and engaged me in your residences – thank you for enriching my sense of life and leadership. I am grateful that Grace and I could support and mentor many of you over the years and see you graduate. I am a better leader because of you.

To the staff of the three campuses – there is no university Rector, I can assure you, who enjoyed more love and support than what you offered me since the day I arrived here. Students come and go, but you have been my foundation year after year, and I thank you for that.

To parents, friends, and followers off-campus, in South Africa and abroad – thank you for hundreds of letters, emails, phone calls, prayers and ‘packages of support’ (from biltong to books). In the most difficult times, you rallied from everywhere with a word of support, often on social media. Know this: your words kept me calm in the storm.

Thank you, everyone.

Goodbye.
