The University of the Free State Library and Information Services (UFSLIS) hosted stakeholders from SABC Lesedi FM, the Free State Department of Sport, Arts, and Culture, the Pan South African Language Board (PanSALB), and delegates from the National Library for the launch of the first-ever African Languages University Press in South Africa and Africa.  The launch, which took place on 24 May, deliberately coincided with the Africa Month commemorations – as the UFS’ answer to the United Nations General Assembly (Resolution A/RES/74/135) proclamation of the period between 2022 and 2032 as the International Decade of Indigenous Languages.  

This proclamation aims to draw global attention to the critical situation of many indigenous languages, and to mobilise stakeholders and resources for their preservation, revitalisation, and promotion. The University of the Free State Department of African Languages aims to be a publisher of high-quality original African language monographs and research in order to promote access, preservation, and use of marginalised African languages.  

In his opening remarks, Marcus Maphile, Assistant Director: Library Services, said, “As a broad academic publisher, the African Languages Press will be working across a number of markets, all presenting challenges and opportunities for established and engaged university presses. One of the opportunities will be to challenge the mainstream book publishers to re-enter the indigenous language publishing market.” He further said that this was done to make writing and reading in African indigenous languages fashionable, for other nations to envy our rich multilingual cultural heritage. 

The guest speaker for the launch was the UFS honorary Doctor of Letters (DLitt) recipient, Dr Jerry Mofokeng wa Makhetha, who applauded the University of the Free State for taking such a bold step towards enriching and developing African indigenous languages. 

The launch offered the UFS the opportunity to reach out and engage the international community on potential partnerships and collaborations towards developing African languages. The Library Director, Ms Jeanette Molopyane, provided insight into the challenges faced by libraries due to the shortage of books in African languages, while positioning the University of the Free State Library as a trendsetter and a leader in the development of best practices in the field of libraries.

Research on cactus pear grabs attention of food, cosmetic and medical industry

The dedicated research and development programme at the UFS on spineless cactus pear (Opuntia ficus-indica) – also known as prickly pear – has grown steadily in both vision and dimension during the past 15 years. Formal cactus pear research at the UFS started with the formation of the Prickly Pear Working Group (PPWG) in June 2002. It has since gone from strength to strength with several MSc dissertations and a PhD thesis as well as popular and scientific publications flowing from this initiative.

According to Prof Wijnand Swart from the Department of Plant Sciences, the UFS is today recognised as a leading institution in the world conducting multi-disciplinary research on spineless cactus pear.

Cactus pear for animal feed

Increasing demands on already scarce water resources in South Africa require alternative sources of animal feed – specifically crops that are more efficient users of water. One alternative with the potential for widespread production is spineless cactus pear. It is 1.14 x more efficient in its use of water than Old man saltbush, 2.8 x more efficient than wheat, 3.75 x more efficient than lucerne and 7.5 x more efficient than rangeland vegetation.

“Studies on the use of sun-dried cactus pear cladodes suggest that it has the potential to provide some 25% of the basic feed resources required by South Africa’s commercial ruminant feed manufacturing sector,” says Prof HO de Waal of the Department of Animal, Wildlife and Grassland Sciences at the UFS.

Until recently, research has focused extensively on the use of cactus pear as drought fodder. However, this is now beginning to shift, with growing interest in the intensive production of spineless cactus pear for other types of animal feed. One example is the spineless cactus pear fruit, produced seasonal, yielding large quantities of fruit in a relatively short period of a few months in summer. Unless kept in cold storage, the fruit cannot be stored for a long period. Therefore, a procedure was developed to combine large volumes of mashed cactus pear fruit with dry hay and straw and preserve it for longer periods as high moisture livestock feed, kuilmoes – a high water content livestock feed similar to silage.

Cactus pear for human consumption

“In addition to its use as a livestock feed, cactus pear is increasingly being cultivated for human consumption. Although the plant can be consumed fresh as a juice or vegetable, significant value can be added through processing. This potential is considerable: the plant can be pickled; preserved as a jam or marmalade; or dried and milled to produce baking flour. It can also serve as a replacement of egg and fat in mayonnaise,” said Dr Maryna de Wit from the Department of Microbial, Biochemical and Food Biotechnology.

The extraction of mucilage from fresh cladodes can form a gelling, emulsifier, and fat-replacing agent commonly found in food products such as mayonnaise and candy. During an information session to the media Dr De Wit and her team conducted a food demonstration to showcase the use of the cladodes in a juice, chicken stir-fry, biscuits and a salad.

The extrusion of cactus pear seed oil provides a further lucrative niche product to the array of uses. These include high-value organic oil for the cosmetic sector, such as soap, hair gel and sun screens.

The cladodes and the fruit also have medicinal uses. It has anti-viral, anti-inflammatory, pain killing and anti-diabetic agents. It is also high in fibre and can lower cholesterol. The fruit also prevents proliferation of cells and suppresses tumour growth and can even help to reduce a hangover.

In South Africa the outdated perception of cactus pears as thorny, alien invaders, is rapidly disappearing. Instead, farmers now recognise that cactus pear can play a vital role as a high yielding, water-efficient, multi-use crop, said Prof de Waal and the members of the Cactus Pear Team.
