Probiotics and enzymes encapsulation using microfluidization has become an effective way to improve microbial viability in the midst of environmental stresses despite ongoing material and technological difficulties. Microfluidic platform provides the accurate creation of carriers such as emulsion, microspheres, and nanofibers. Customized design, such as cationic coatings to decrease pore diameters in alginate hydrogel, provides regulated release and enhanced stomach survival. But their limitation is that monovalent ions destabilize exposed structure and calcium alginate destroys cell walls during processing. Therefore, composite material like chitosan-alginate blends is required for increasing stability. Future developments will concentrate on improving material biocompatibility using engineered biofilms and plant-derived polyphenols, as well as co-encapsulation techniques that incorporate prebiotics or bioactive substances for complementary effects. While scalable manufacturing techniques like triple-nozzle spray drying require tuning, strain specific needs may be satisfied via microbial mediated system and precision single cell encapsulation. Bridge scientific efficacy with commercial application requires in vivo confirmation of regulated strategies in a variety of food matrices, from dairy to dry based goods. Personalized delivery methods that are suited to host-microbiome interaction and gastrointestinal dynamics may be made possible by advancements in microfluidic device combined with multi-omics assessments of encapsulated probiotics and enzymes functionality.
