520 |a This study investigated the survival of encapsulated potential probiotic Lactobacillus plantarum which isolated from fermented cocoa beans. κ-Carrageenan was used to encapsulate the probiotic. Encapsulation techniques such as emulsification, freeze-drying or extrusion were adopted to encapsulate the probiotic. Freeze-drying and extrusion methods showed higher (p < 0.05) efficiency (89.48 ± 3.21 and 92.26 ± 1.45%, respectively) in encapsulating the probiotic compared to the emulsification method (82.19 ± 0.71% efficiency). Freeze-dried encapsulated probiotic L. plantarum was selected for further survival analysis as greater amount of beads were produced compared to the extrusion method. Freeze-dried probiotic was found to have significantly (p < 0.05) higher tolerance to acid at pH 2 with higher survival percentage compared to non-encapsulated probiotic. However, freeze-drying encapsulation was proven not to enhance the resistance of the probiotic to bile salt as evidenced by the one log colony reduction as for the non-encapsulated probiotic. Further modification of freeze-drying encapsulation technique is needed to enhance the survival of the encapsulated potential probiotic L. plantarum toward bile salt in the future
