Qinisani Qwabe, one of the Mail & Guardian Top 200 Young South Africans, considers it important to always reach out and contribute to someone's life, no matter how small it may be.

Looking back at 2020, most people will not have fond memories. But for Qinisani Qwabe, a second-year PhD student in the Centre for Sustainable Agriculture, Rural Development and Extension, 2020 turned out to be a good year.

On 10 September, he heard that he was selected as one of the Mail & Guardian Top 200 Young South Africans in the education category. As if being elected as one of the prestigious group of young people is not enough, Qwabe added another feather in his cap when he was chosen as one of 21 young scientists by the Academy of Science of South Africa (ASSAf), in collaboration with the Department of Science and Innovation (DSI). 

When offered the chance to represent South Africa at a BRICS Conference in Russia, he seized the opportunity with both hands. At this virtual event, he presented a paper on a topic he cares about a lot – ecology. His paper, using a South African case study, was titled: The role of agrobiodiversity on environmental management and its impact on human ecology.

Sustainable resources

From an early age, growing up in a very isolated community called iSihuzu on the outskirts of Richards Bay, Qwabe worked hard. He not only reaped the rewards by seeing all his tuition fees paid, but he was also offered opportunities to make a difference in society. 

“I want to see a society that leads a sustainable life and values its natural resources. This is what wakes me up every morning. That is what I am working towards,” he says.

Qwabe has a registered organisation that, among others, seeks to achieve agricultural biodiversity, respect and value for local knowledge, sustainable development, as well as youth and community engagement.  

The organisation has two legs – one dealing with agricultural production and the other focusing on social entrepreneurship. “As part of this social entrepreneurship initiative, we are working with schools in the north of KwaZulu-Natal, where we do outreach programmes (e.g. donating school uniforms), and run projects driven towards sustainability,” says Qwabe.

But he believes that it is his voice on indigenous foods, together with his passion for research – complemented by community development initiatives – that contributed to his selection as one of Mail & Guardian’s top 200 Young South Africans. 

A greater vision

He is happy to be in the academia and believes that it will propel him towards his greater vision. 

“My vision for my future is to be well-known for my contributions on matters of environmental sustainability, and equally so, for community development. Parallel to my philanthropic undertakings, I envision being a leader in one of the leading organisations on environmental sustainability, such as the World Health Organisation's Food and Agricultural Organisation (FAO),” says Qwabe. 

Here he would like to focus his energies on food security, nutrition, and food safety; sustainable management and use of natural resources and forestry; and institutional capacity building for the sustained management of natural resources and increased agriculture production.

The next generation

Qwabe believes he is making an impact and building a solid foundation for the upcoming generations to build upon.  He urges the youth of South Africa to strive to make a difference. “No matter how small it might seem,” he says.

“To borrow from the American songwriter, Michael Jackson – WE are the world. And that 'WEness' denotes that each one of us has a role to play.

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.
