To exert their probiotic activity, bacteria need to be viable when
reaching the intestine. Microencapsulation is undeniably one solution.
This technology is used to maintain probiotic viability from their processing up to their consumption and their passage through
the gastrointestinal tract by entrapping and protecting sensitive
living cells (De Prisco and Mauriello, 2016). Many microencapsulation
technologies are successful in encapsulating probiotic bacteria,
e.g., spray-drying, emulsion, coacervation, extrusion, fluid bed
or gel-particle technologies
