Postbiotics Preparation for Use in Food and Beverages

Postbiotics are considered novel bioactive compounds, since there is not yet a consensus about its definition; however, many postbiotic compounds are already used in the food industry to provide food preservation, in the manufacture of bioactive food packaging, control bacterial biofilm, or provide functional effects to food products. The postbiotics can be applied to food as a mixture (several compounds, often called cell-free supernatant) or a separated form; however, there are issues about the production of these postbiotics and the practical application to different food products. This chapter aims to present the most used methodologies and the details about its production and application.
