Unveiling the potential of African fermented cereal-based beverages: Probiotics, functional drinks, health benefits and bioactive components

Abstract

Traditionally, dairy products have been the primary medium for delivering probiotics to humans. However, despite their numerous health benefits, such as nutrient supply and prevention and treatment of certain diseases, there are limitations to their use in many regions, including Africa. These limitations arise from allergens, lactose intolerance, hypercholesterolemia effects, the need for vegetarian options, cultural food taboos against milk, and religious beliefs. As a result, research efforts worldwide have focused on probiotics with health benefits. To address this issue, an integrative approach has been adopted, consolidating ideas and concepts from various studies. Researchers have explored different food matrices to determine their potential as probiotic carriers, specifically emphasizing cereals and cereal products. Studies have revealed that traditional African fermented cereal-based beverages show promise as probiotic carriers due to the presence of probiotic organisms involved in the fermentation process. This presents an opportunity to utilize African cereal beverages to deliver. This review paper provides comprehensive information on probiotics, including their sources, types, health benefits, and delivery vehicles. Specifically, it highlights the challenges and prospects for developing and consuming cereal-based probiotics in Africa. This opens up new avenues for providing probiotic benefits to a broader African population and contributes to the advancement of probiotic research and development in the region.
