 ABSTRACT

The present study adopted microencapsulation of bacteria to enhance its viability. Watermelon juice was found to be a suitable media for the growth of probiotic L.rhamnosus GG showing prebiotic effect. No significant difference in the viability of L.rhamnosus GG in MRS medium. The average viable count (log10cfu/ml) of L.rhamnosus GG in watermelon and MRS medium were 10.53±0.136 and 10.55±0.132 respectively. The survivability assessment of L.rhamnosus GG in microencapsulated beads at different storage conditions was studied. The probiotic level of 108 cfu/g of L.rhamnosus GG was maintained at both temperatures till 21 days of storage. The viability of L.rhamnosus GG was 8.404±0.019 and 8.027±0.008 log10cfu/ml in microencapsulated beads at refrigeration and ambient temperature respectively on 21st day of storage after which there was a decline in the probiotic count in samples stored at ambient and refrigeration temperature.
