| Abstract | ||
| To enhance the viability and effectiveness of Lactiplantibacillus plantarum SN13T as a probiotic, protection can be provided to the bacteria through encapsulation methods. This study aims to determine the best wall material formulation, consisting of alginate and bengkuang flour (Pachyrhizuz erosus), in the encapsulation process of L. plantarum SN13T. In this research, the encapsulated bacteria (beads) will be tested for their characteristics, including moisture content, bead size and morphology, total lactic acid bacteria, resistance to simulated gastric juice (SGJ) and simulated intestinal juice (SIJ), as well as encapsulation efficiency. The treatments in this study are combinations of 1% alginate wall with bengkuang flour: A = without the addition of bengkuang flour (control), B = 1% bengkuang flour, C = 3% bengkuang flour, and D = 5% bengkuang flour. The results indicate that encapsulation of L. plantarum SN13T using alginate and bengkuang flour as wall materials, specifically the use of 1% alginate + 1% bengkuang flour produces the best encapsulation results, with a moisture content of 97.34%, bead size of 2.14 mm, total lactic acid bacteria colony count of 12.88 log CFU/mL, resistance to SGJ of 95.23%, and resistance to SIJ of 95.76%. This demonstrates that encapsulation with a formulation composition of 1% alginate + 1% bengkuang flour provides optimal results for the viability and effectiveness of L. plantarum SN13T. Bengkuang flour, which contains starch, is recommended as a wall material for the encapsulation process of probiotic bacteria. | ||
