The Functionality of Probiotic Bacteria Microencapsulation by Spray Drying: A Literature Review

Abstract

Probiotic-based products are associated with many health benefits. The viability of probiotics is necessary to provide health benefits, but it is lost during processing, storage, and gastrointestinal tract. The viability of probiotics can be maintained by applying the spray drying encapsulation technique. This review article discusses probiotic bacteria, encapsulant ingredients, the principle of spray drying in microencapsulation, and the functional properties of spray drying probiotic microcapsules. This article uses a non-research method with a literature review of various sources such as research journals and related books. Based on existing studies, the viability of probiotic spray drying results is influenced by the bacterial culture used, the type and concentration of the encapsulated material, and the spray drying conditions (feed temperature, inlet temperature, and outlet temperature). Probiotic microcapsules spray drying has excellent potential in functional food formulations, and its commercial applications will benefit both the industry and consumers.
