In recent years, probiotic functional foods have gained quite a popularity and become a preferred choice among consumers, due to their positive effects on the gut microbiota and overall health. However, it is imperative for a probiotic strain to remain live and active at the time of consumption in high enough population density, in order to provide such health benefits. Thus, this study aimed to investigate the Bacillus coagulans MTCC 5856 spore stability after tea and coffee brewing and its subsequent growth in gastrointestinal tract (GIT) hostile environment. B. coagulans MTCC 5856 showed remarkable survival (94.94% and 99.76% in unroasted green coffee and tea, respectively) after brewing conditions and was able to grow in GIT hostile conditions using tea and coffee as a sole nutritional source. B. coagulans MTCC 5856 inclusion in tea and coffee after brewing did not significantly (P > .05) alter the sensory profile when compared to that without the probiotic inclusion. Moreover, B. coagulans MTCC 5856 growth was significantly (P < .05) higher when water soluble fibers were added during brewing, suggesting a synergistic property. It showed over 99% viability (P > .05) in tea and coffee powder at room temperature up to 24 months of storage. This study demonstrated the stability of the tested probiotic strain B. coagulans MTCC 5856 after tea and coffee brewing and its growth in GIT hostile environment, thereby suggesting functional probiotic use in tea and coffee.
