Potato peel has high dietary content which makes it natural prebiotic source and in recent years there is a lot of interest in using natural prebiotics as functional food ingredients to change the composition of colonic microbiota and improve health. Main prebiotic dietary fibre component of potato peel is resistant starch (RS) and it differ in raw and boiled potato peel. Hence the present study was planned with the aim to compare the prebiotic effects of raw potato peel (RPP) and boiled potato peel (BPP) powders on growth of isolated probiotic bacteria. The isolated strain PI-1 demonstrated higher bile tolerance (0.3%), higher hydrophobicity index and higher co-aggregation property, indicating its probiotic nature and identified as a Lactiplantibacillus pentosus/Plantarum / Paraplantarum which is potential probiotic. The isolate was able to grow qualitatively in all of the tested concentrations of RPP and BPP (1% -10%). Under acidic conditions of pH-2.0, a similar pH of stomach, RPP and BPP enhanced the survivability of isolated probiotic compared to glucose. In vitro digestibility of RPP and BPP revelated BPP has better ability to thrive under simulated gastric conditions. The isolate inhibited growth of Escherichia coli and Staphylococcus aureus in presence of glucose but no inhibition was seen in presence of RPP and BPP. The current study presents an intriguing economic strategy for modulating probiotics by adding agri-food wastes as a prebiotic while also improving their survival under GIT, with a concomitant effect on host health.
