Co-encapsulation of probiotics and microalgae-derived pigments is proving to be an innovative approach to develop functional foods with enhanced health benefits. Microalgae pigments, including carotenoids (e.g., astaxanthin, β-carotene, lutein, fucoxanthin) and chlorophyll, are highlighted for their potent antioxidant, anti-inflammatory, and disease-preventing properties. These pigments are favored over synthetic colorants due to their superior bioactivity, sustainability, and cost-effectiveness. They also contribute to improved cardiovascular health, immune modulation, and prevention of chronic diseases such as cancer and macular degeneration. Probiotics, known for their positive effects on gut health and immune system modulation, require stabilization during storage and gastrointestinal transit to maintain efficacy. Microencapsulation emerges as a vital technology to protect these bioactive components from environmental degradation, thereby enhancing their functionality and enabling controlled release. Techniques such as spray drying and emulsification are particularly effective in preserving the stability and bioactivity of probiotics and pigments. The combination of these two bioactive components offers synergistic effects, creating nutraceuticals with applications in improving antioxidant capacity, gut health, and overall immune support. However, despite the promising individual health benefits of probiotics and pigments, the combined effects of their co-encapsulation remain underexplored. The paper emphasizes the need for further in vivo and in vitro studies to demonstrate these synergistic advantages. This research highlights the potential of co-encapsulation as a sustainable and efficient strategy for functional food innovation, addressing industrial challenges related to stability and bioavailability, while advancing global health outcomes.
