The year 2023 marks the diamond jubilee of the establishment of the Organisation of African Unity (OAU), currently known as the African Union (AU), which was founded in Addis Ababa. The visionary founders, including President Kwame Nkrumah and Emperor Haile Selassie, aimed to bring about political change in African states and restore the dignity of African people, who had long suffered under colonial subjugation and disenfranchisement. Their vision encompassed a united Africa, free from oppression, governed by self-determination, and destined for prosperity.

Over time, the OAU transformed into the AU, with the intention of accelerating the dream of African unity and eradicating the social, political, and economic challenges that had begun to define African states. Pan-Africanism emerged as a beacon of hope, inspiring many who understood its significance at the organisation's inception. As we reflect on the ideals cherished by the founding fathers and reaffirmed by their successors in 2002, it is crucial to contemplate four of the seventeen aims articulated during the launch of the African Union in Durban.

Unity and solidarity between African countries and their people

Firstly, the AU aims to achieve greater unity and solidarity between African countries and their people. In pursuit of this goal, notable actions have been taken, such as the establishment of the Peace and Security Council (PSC) to maintain peace in conflict zones such as Mali, Sudan, Somalia, and the Central African Republic. Moreover, in response to the COVID-19 pandemic, the AU set up the Africa Medical Supplies Platform (AMSP) to facilitate the procurement and distribution of medical equipment and supplies throughout the continent. While these achievements are commendable, the majority of the other intentions under this aim lack a concrete plan of action, and the lack of sufficient funding is hampering progress. This presents a cause for concern.

Secondly, the AU pledged to defend the sovereignty, territorial integrity, and independence of its member states. Despite the development of intervention instruments to support this aim, the organisation has been found wanting at critical junctures. One cannot forget the adoption of Resolution 1973 by the United Nations Security Council, which authorised national governments or regional organisations to impose a no-fly zone in Libya, ultimately leading to the assassination of Colonel Muammar Gaddafi. Colonel Gadhafi played a pivotal role in the formation of the African Union and declared his vision for the United States of Africa with a single government and one currency. Surprisingly, three AU member states – South Africa, Nigeria, and Gabon – voted in favour of this resolution. Their actions raised doubts about their commitment to defending the sovereignty, territorial integrity, and independence of the AU.

Africa faces a harsh reality

Africa, a continent with immense potential for growth and development, faces a harsh reality that cannot be ignored. Its burgeoning population holds great promise for contributing significantly to its advancement. Additionally, Africa is blessed with abundant mineral resources, the prudent management of which could sustain the developmental aspirations of its people. Furthermore, Africa's expansive land mass and diverse climate present valuable opportunities to address crucial concerns such as food and energy security. It is perplexing that Africa, a continent three times the size of the United States of America, continues to lag behind in all aspects of development. The continent has enormous potential to foster growth and development and to compete on a global scale. Regrettably, it has thus far failed to harness this potential, leaving the dream of African prosperity, initially envisioned by the founders of the OAU (AU) and their successors, frustratingly out of reach.

As we commemorate the diamond jubilee of the OAU's establishment, let it serve as a reminder of the vision and determination of its founders. Their dreams for an Africa united, free from oppression, and governed by self-determination still resonate today. It is our collective responsibility to ensure that these dreams are no longer scuppered, but rather transformed into a vibrant reality of African prosperity.

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.
