Indigenous processing and microbial dynamics of Metata Ayib: a traditional fermented dairy product in Ethiopia

Metata Ayib is a type of cottage cheese, which is produced in different areas of Ethiopia with varying procedures. The production of this fermented dairy product is an important method to preserve milk for a long time. Various areas produce Metata Ayib with varying nutritional composition, flavor, and shelf life. Metata Ayib is prepared from Ayib (cottage cheese) through a spontaneous fermentation process for 15–20 days while utilizing diverse spice combinations. In this preparatory project phase, we will design a project to investigate Metata Ayib production procedure, and uses of the product in the selected area. Samples will be collected from selected areas to determine the safety and quality of Metata Ayib. The various spice types and their levels, fermentation time and temperature will be optimized. The microbial dynamics in the fermentation process will be assessed. Bahir Dar Institute of Technology (Ethiopia) and University of Natural Resources and Life Sciences, Vienna (BOKU, Austria) will collaborate and be involved in the project's execution. An effective project proposal is created during the planning phase through collaborative academic discussion and inquisitive intellectual debate. The project design process will include participation from traditional Metata Ayib producers, dairy cooperatives, dairy industries, policymakers, and other stakeholders. The approach will create a forum where thoughts and information from people and groups with diverse cultures, economies, and social networks can be exchanged. The findings of the proposal results will contribute to a greater understanding of locally produced Metata Ayib, which will be advantageous to both local producers and consumers. Additionally, it will be encouraged to enhance the food security and living standards of the direct beneficiaries (small-scale dairy farmers) as well as the indirect beneficiaries, which include consumers, the dairy industry, and early-career researchers.
