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.

First-year students encouraged to attend UFS welcoming function
2007-01-12

Main Campus, Bloemfontein
The University of the Free State (UFS) will host a welcoming function for all new first-year students and their parents on Saturday 13 January 2007 in the Callie Human Centre on the Main Campus in Bloemfontein.
 
The function starts at 11:00 and will be addressed by the Rector and Vice-Chancellor of the UFS, Prof Frederick Fourie. UFS staff will also be available to provide vital information to first-year students on academic matters.
 
Saturday’s welcoming function can assist students and parents by providing vital information on the registration process, which starts on Tuesday 16 January 2007, and the many high quality academic learning programmes on offer in six faculties at the UFS.
 
The UFS has split the registration process into various categories of students and students should adhere to the dates, and times which apply to them as a one-stop service will be available so as to avoid unnecessary delays in the registration process.
 
The registration of first-time entering first-year students who applied before 30 November 2006 to study at the Bloemfontein Campus will take place from Tuesday 16 January 2007 at the Callie Human Centre.
 
Senior undergraduate students (that is, students entering their second or later year of study) may register from 22 January 2007 according to a programme that was sent to all students who were registered at the UFS in 2006.
 
Postgraduate students, first-time entering first-year students and other students, who applied for admission to the Main Campus after 30 November 2006 and were accepted, must register at the Callie Human from 5 February 2007. 
 
Late applications will be accepted until Monday 15 January 2007 at the Information Centre on the Main Campus’ Thakaneng Bridge. 
 
Lectures will commence on 5 February 2007 and the registration process will end on 9 February 2007.
 
Vista Campus:
The Vista Campus in Bloemfontein – which was incorporated into the UFS in January 2004 – no longer accepts applications from first-year students. Such prospective students had to apply to the UFS Main Campus. Students who had been registered on the Vista Campus last year must register at the Vista Campus on the same dates as applicable on the Main Campus.
 
Qwaqwa Campus:
At the Qwaqwa Campus of the UFS all first-time entering first-year students must report on Sunday 14 January 2007 for orientation, after which the registration of these students will take place according to a specific programme as from Wednesday 17 January 2007. The official welcoming functioning for new first-years at the Qwaqwa Campus of the UFS will take place on Saturday 10 February 2007 at 08:00 in the Rolihlahla Mandela Hall on the Qwaqwa Campus.
 
First-year students who have applied to study at the Qwaqwa Campus and their parents should attend this function which fulfils the same role as the one held on the Bloemfontein Main Campus.
 
Detailed information on the dates and times of registration for the various faculties and academic learning programmes is available on the UFS website at www.ufs.ac.za
 
Prospective students may also call the Main Campus in Bloemfontein on 051 4013000 or the Qwaqwa Campus on 058 718-5000 for more information.
