Contribution of indigenous food preservation and processing practices to food security of rural households in Sekhukhune district of Limpopo province, South Africa

Abstract

Rural people have the indigenous knowledge of processing and preserving food to ensure household food security during times of food scarcity. Although indigenous knowledge plays an important role in ensuring household food security for many rural households, it is often overlooked as a solution to address food and nutrition insecurity. The main objective of the study was to identify and document indigenous food preservation and processing techniques used by rural women to ensure household food security. Qualitative data were collected from small-scale farming households in seven villages through focus group discussions, individual interviews, and observations. The researchers adhered to ethical considerations (approvals, permissions with the relevant authorities, consent from participants, their privacy, anonymity, and confidentiality) throughout the research process. Data were analysed using thematic content analysis. The results indicate that sun-drying and fermentation were the most commonly used methods for food preservation, while the most prevalent methods used for processing vegetables (merogo) involved cooking, mashing, pelleting and sun-drying. Crops, such as mung beans, bambara groundnuts and sorghum are threshed and winnowed to remove all impurities. The seeds, which are to be used in the next planting season, are treated with aloe ash to prevent pest infestation. Indigenous fruits are gathered from the wild and eaten as snacks. Indigenous dried vegetables (merogo) and fermented marula beer were sold to generate income that is used to buy other basic food items. The paper concludes by highlighting the existing indigenous knowledge that rural households demonstrate in terms of food processing and preservation. Given the existing knowledge and the commonly used methods for preserving and processing food, it is crucial to create awareness regarding ways of retaining nutrients during food preservation and processing to ensure availability and proper utilisation of indigenous foods for household food security purposes. The study recommends that these methods, including ways of retaining nutrients, be documented and made easily accessible for rural households to use now and in the future for ensuring household food and nutrition security. Therefore, there is a need for agricultural and food security policies to embrace, adopt, promote and adapt indigenous knowledge and technologies to address food security.
