Tradition and Innovation in Yoghurt from a Functional Perspective—A Review

Yoghurt is one of the most consumed and studied dairy products, with proven functional effects on the human body. This review discusses the functional properties of traditional yoghurt products in comparison with different other yoghurts enriched with natural bioactive compounds like bee products, aromatic plants, fruit, vegetables, extracts, edible flowers, mushrooms, and high protein ingredients. The food industry aims to enhance the nutritional profile of final products, recognising the potential value they bring. Yoghurt, acknowledged as a functional food, has garnered significant attention globally in terms of production and consumption. Incorporating flavours through essences, fruit, fruit extracts, and honey is considered a preferable alternative to artificial flavours for innovating new dairy products. While the review underscores the positive properties of natural additives, it also addresses the possible changes in physicochemical properties and storage stability when yoghurt is enriched beyond the basic elements. A compelling synthesis of the data reveals the remarkable finding that the majority of functional yoghurts incorporate bee products. In recent years, the dairy industry has seen a rise in combining probiotics and functional foods, especially with the development of probiotic functional yoghurts.
