Recent Trends in Fermented Beverages Processing: The Use of Emerging Technologies

Since ancient times, fermentation has been one of the most utilized techniques for food preservation and for the development of natural products with functional properties at low cost. Nowadays, fermented foods and beverages are highly attractive to consumers since they are perceived as natural and potential sources of functional compounds. Research efforts conducted in this area over the years have allowed for an understanding of the main reactions occurring during fermentation related to microbial growth, enzyme activity, metabolite production, and physicochemical changes. As a result, scientists and technologists have been able to improve the fermentation process in terms of efficiency, safety, costs, and high-quality production of products. The aim of this review was to gather the most recent and relevant information about fermentation evolution during the last decades, focused on the application of emerging technologies for the development of fermented beverages as interesting products in the functional food market.
