Probiotics, beneficial microorganisms that can enhance human health, are susceptible to adverse effects from processing and storage and passage through the gastrointestinal tract. Various conventional and nonconventional formulations are accessible for administering probiotics, with the latter subject to fewer regulatory guidelines. Pharmaceutical formulations, part of the conventional category, are specifically crafted to deliver an effective quantity of viable microorganisms. However, probiotics are particularly sensitive to environmental and processing factors, which can compromise their viability within the final formulation. This review addresses a significant gap in the current literature by focussing on the encapsulation technologies developed to enhance the stability of probiotics throughout the storage period, providing physical protection through the digestive system and improving their colonisation ability. Key advancements in encapsulation processes, including innovative approaches, thermal treatments and strategies to overcome gastrointestinal conditions, are discussed in this review.
