Abstract:

The marula tree (Sclerocarya birrea, A. Rich.; Hoscht subspecies caffra, Sond) is a member of the Anacardiaceae which encompasses 73 genera and 600 species (Pretorius et al., 1985). This tree is distributed throughout Africa with its southern most location in the lowlands of KwaZulu-Natal (South Africa) from where it extends northwards through tropical Africa into Ethiopia and Sudan (VanWyk, 1974). Of all fruit trees indigenous to South Africa, the marula has received most attention in terms of domestication and commercialization (Shackleton, 1996). Several products such as beer, juice, jam an

Sub-Saharan Africa is a treasure chest of natural materials remaining to be explored for commercial applications and as alternative foods to diversify and improve food sustainability. The Marula tree is available in abundance in South Africa and bears a fruit with a highly nutritious kernel containing high oil and protein content. The oil from the kernels has various applications from food to cosmetics. The accepted oil processing practice is required to be a green technology, producing no effluent or using toxic solvents. Therefore, the oil is extracted using an expeller. However, with averag

MaxEnt modelling uses only the known locations of a species to predict the overall distribution of a species. Large trees are important for the functioning of savanna ecosystems, bringing nutrients to the surface, providing shelter to animals and providing a number of ecological functions. Large trees have been identified as declining in density in many southern African reserves, making the conservation of large trees within reserves an issue in park management, such as in Kruger National Park (KNP) and Hluhluwe iMfolzi Parks (HiP).

One product that has recently entered into local commercial markets is a traditional alcoholic beverage brewed from the fruits of Sclerocarya birrea (marula), commonly known as marula beer. It was rarely traded in the past due to customary taboos prohibiting its sale. In Bushbuckridge, Limpopo province, rural women have been selling marula beer in the business centres of the district and along the roadside since 1998. A survey of thes
