Poverty and especially rural poverty, is becoming an increasing problem in South Africa, as well as in the whole of Africa. This is leading to urbanization, food insecurity and joblessness. An estimated 20% of the African population is undernourished. In 2022, around 868 million people in Africa experienced moderate to severe food insecurity, while the total population of Africa was approximately 1.42 billion in the same year. Food insecurity can be attributed to poverty, extreme weather and conflict.

One Solution to Food Insecurity

Root and tuber crops, such as sweet potatoes, are important for food security. As a drought-tolerant crop, sweet potatoes are resilient in warm climates like those in sub-Saharan Africa. They are a staple food globally, especially in developing countries, providing affordable and accessible nutrition. Sweet potatoes hold great economic value in South Africa. However, after harvest, there is a limited time to determine when they are good to eat. They are harvested once a year and are ripe for a limited period.

InnoFoodAfrica

InnoFoodAfrica is a cross-continental project that aims to enhance food and nutrition security in Africa. As part of this project, researchers at the University of Pretoria, South Africa, have found a way to make orange-fleshed sweet potato last longer by making flour out of it. A Doctor of Philosophy (PhD) Food Science candidate, Daddy Kgonothi, has been central in the development of this flour. The goal of the invention was to address micronutrient deficiencies among young children and pregnant women.

Sweet potato has a short shelf life of only two to three weeks. The flour, which is made from the same crop, has a shelf life of a whole year. Sweet potato contains beta-carotene, which is converted into vitamin A in the body. Vitamin A deficiency is one of the leading causes of micronutrient deficiencies in children younger than 6 and among pregnant women. Sweet potato also contains a high level of fiber and antioxidants. This protects the body from free radical damage and promotes a healthy gut and brain.

Flour is also a good source of iron, zinc and phosphorus. When sweet potato is made into flour, it lasts longer, which can lead to more people getting their hands on the product. It is also versatile and can be used in many recipes, such as bread. This way, the flour can be a solution to deficiencies.

The Impacts of the Sweet Potato Flour

The flour is one solution to food insecurity in not only South Africa but also large parts of Africa. The development of the flour was finalized in 2022. It allows people to enjoy the nutrients and benefits of the crop all year long. Not only is the flour helping enhance general food insecurity in South Africa and the rest of Africa, but it is especially helping pregnant women and children eat more nutritious food.
