Alina Ntsiapane obtained second place in the partners division of the ILRI CapDev Grand Challenge research pitching contest.

Alina Ntsiapane, a PhD student at the University of the Free State, obtained second place in the partners category of the International Livestock Research Institute’s (ILRI) CapDev Grand Challenge research pitching contest, which took place on 13 April 2022. The pitching contest is the first part of the CapDev Grand Challenge, which is a 10-month process aimed at equipping scientists with the necessary skills to contribute to new research. 

Presenting Research to a Tough Panel of Judges 

Ntsiapane was one of 30 contestants who presented their research virtually to a panel of esteemed judges. “It was not easy, it was very challenging for me because it was my first time presenting my PhD study and I had to do it live on an international platform,” expressed Ntsiapane. Although each contestant is thoroughly prepared for their respective presentations, Ntsiapane argues that some of the questions asked by the judges can be quite daunting. “Some of their questions were very challenging and I did not know how to respond to them, but they made me aware of ways in which I needed to improve my research,” she stated. However, regardless of the intensity of the pitching contest, Ntsiapane’s research allowed her to progress to the next stage of the CapDev Grand Challenge. She will be part of the rigorous 10-month training process that will begin in June 2022.

Ntsiapane’s Research Project

Ntsiapane’s PhD research focuses on the production of smallholder wool as a means to improve livelihoods in both Thaba ’Nchu and Botshabelo in the Free State. In fact, in the research Ntsiapane highlights that there has been a significant decline in the production of wool within the last three decades. As such, Ntsiapane believes it is imperative to create spaces that allow for the training of small-scale farmers, so that the production of wool can still be a possibility.
Consequently, Ntsiapane hopes that the 10-month training she will receive from the CapDev Grand Challenge will not only allow her to grow but will assist in opening doors for her. “I’m hoping to get exposure and to make connections with policy makers and the donors as well. This will assist me in achieving my goals,” she explained. 

Future Endeavours After the Training Course

Subsequent to the training course, Ntsiapane would like to utilise that knowledge by continuing to make her most recent project a reality. Ntsiapane is currently working on developing a television show aimed at providing adequate training to small-scale farmers, so that they are equipped with the necessary knowledge and understanding of the industry in which they find themselves. As such, being part of the CapDev Grand Challenge will allow her to learn some of the necessary ways in which this dream could become a reality.

From wheat protein to perfect pizza

Barend Wentzel, an alumnus of the University of the Free State’s Department of Plant Sciences, is passionate about plant breeding. 

He literally eats and lives wheat proteins. In 1989 he initiated a breeding programme on arum lilies. “This breeding programme is at an advanced stage,” he said. Besides reading, playing the piano and accordion, Barend, due to the nature of his research at the Agricultural Research Council, also experiments with different types of ciabatta recipes made from sour dough. “I usually make my own pizza on Saturday evenings,” he said.

He is working at the Agricultural Research Council – Small Grain (ARC-SG) at the Wheat Quality Laboratory where he established a Cereal Chemistry Laboratory.

Complexity of flour quality

He explains that the focus of his research is on wheat protein composition. “The research conducted for my PhD study explains the complexity of flour quality to a certain extent, and it further emphasises the influence of the environment and genetic composition on selected baking characteristics. 

“Wheat protein can be divided into different types of protein fractions. These protein fractions contribute differently to dough properties and baking quality and the expression is affected by different components in the environment, including locality, rainfall and temperature. 

“Protein content alone does, however, not explain the variation in baking quality parameters, such as mixing time, dough strength and extensibility, and loaf volume.

“Several methods can be applied to quantify the different protein fractions. I am using high-performance liquid-chromatography (HPLC). The procedure entails the separation of a wheat protein extract through a column with chromatographic packing material. The injected sample is pumped through the column (known as the stationary phase) with a solvent (known as the mobile phase). The specific procedure, size-exclusion high-performance liquid-chromatography (SE-HPLC), is also used by the university’s Department of Plant Breeding, as well as in several international Cereal Chemistry Laboratories,” said Barend.

Dough strength and to loaf volume
“One of the highlights from the study was the positive contribution of the albumin and globulin protein fractions to dough strength and to loaf volume. The findings were wheat cultivar specific and the growing environment influenced the expression. The contribution of these protein fractions was much larger than previously reported for South African wheat cultivars,” said Barend. 
“Previous reports indicated that these protein fractions had a non-specific contribution to the gluten network during dough formation. The findings from this PhD justify further research on albumins and globulin proteins.” 

The Cereal Chemistry Laboratory at ARC-SG is involved in postgraduate student training under Barend’s guidance. He serves as co-promoter for several MSc and PhD students. He is also a collaborator on an international project with the International Maize and Wheat Improvement Centre (CIMMYT) in Mexico. Barend is furthermore working on improving wheat quality for processing and health purposes as a member of the expert working group of the International Wheat Initiative.
