MICROENCAPSULATION OF BIFIDOBACTERIUM LACTIS Bi-07 WITH GALACTOOLIGOSACCHARIDES USING CO-EXTRUSION TECHNIQUE

Probiotics play an important role in human gut health. However, it remains a challenge to maintain the viability of probiotics throughout gastrointestinal transit. Hence, this study aimed microencapsulate Bifidobacterium lactis Bi-07 with galactooligosaccharides (GOS) using co-extrusion technique. Optimization calcium chloride (1.0% w/v 3.0% w/v) and GOS concentration 5.0% were performed encapsulation B. based on bead size microencapsulation efficiency. The found that microbead prepared 1.5% (w/v) sodium alginate, 2.0% showed highest produced was 735.69 μm efficiency more than 94%. Besides, compared between beads or without GOS. Results encapsulated had larger lower probiotic cells Furthermore, free subjected simulated treatment where cell evaluated. Encapsulated higher after treatment. viable count remained 107 CFU/mL. This optimized could survive confer health benefits potential be incorporated into functional foods.
