Özet

Microencapsulation is an effective technique for stabilizing and maintaining the viability of

probiotic microorganisms under stress conditions. In this study, Lactobacillus pentosus cells

were encapsulated using different coating materials-reconstituted skim milk (RSM), gum

arabic (GA), and maltodextrin (MD)-via the freeze-drying method. The resulting

microcapsules were evaluated for their ability to enhance probiotic survival under various

stress conditions, including simulated gastrointestinal environments. The survivability of

encapsulated cells were assessed in simulated gastric and intestinal fluids. Among the tested

formulations, microcapsules prepared with the RSM:GA combination demonstrated

significantly higher viability. A reduction of approximately 2-3 log CFU/mL in viable cell

counts was observed under both gastric and intestinal conditions. These findings suggest

that the RSM:GA coating matrix offers superior protection to

L. pentosus during gastrointestinal transit. The use of naturally sourced, food-compatible

coating agents such as RSM:GA enables the development of clean label products.

Microencapsulation allows for targeted release of probiotics (capsules that open in the

intestine or stomach), which is an important step in personalised nutrition approaches.
