abstract = "Chitosan and nanofiber chitin could safeguard L. casei from a stomach environment. The objective of this research was to determine the effectivity of the encapsulation formulation on the L. casei survivability within an SGF. The beads forming was done by extrusion. Encapsulation materials were varied using 1% alginate, nanofiber chitin (0.2%, 0.6%, 1%, and 2%) and chitosan (0.2%, 0.6%, 1%, and 2%) on the flow rate 1 mL/min and the voltage 0 kV. The resulting beads were immersed for 1, 60, and 120 minutes at 37°C within SGF (pH of 1.2 and 3). The higher chitosan or nanofiber chitin concentration, the higher survivability of L. casei within SGF. The composition of chitosan (2%) and nanofiber chitin (2%) as the encapsulation materials showed the highest viability of 8.08 log CFU/g (survivability of 70.31%) and 9.40 log CFU/g (survivability of 81.78%) within SGF pH 1.2 and 3 for 120 min, respectively.",
