Screening of probiotic strains for development of ready- to -serve probioticated mango beverage
Keywords:Probiotics,, Mango beverage, Lactobacillius helveticus, Non-dairy probiotics, Cell population, Sensory scores
Out of the thirteen probiotic strains procured from different sources or isolated from the commercially available sachets, seven isolates showed growth in the ready to serve (RTS) mango beverage. Among the seven strains, only three strains, i.e., Lactobacillus helveticus MTCC 5463, L. rhamnosus MTCC 5946 and Saccharomyces boulardii showed significant growth in the mango beverage. These three strains were further evaluated for population build-up, physico-chemical and sensory evaluation parameters in the fermented mango beverage. Based on the results of sensory scores, minimum threshold population required for classification as probioticated beverage and physico-chemical characteristics, L. helveticus was used for probiotication of the RTS mango beverage. Mango beverage fermented with L. helveticus MTCC 5463 showed an average score of 7.34 on a hedonic scale of 9 for overall acceptability, had an acidity of 0.29%, sugar concentration of 7.6% and pH of 4.4. Probioticated mango beverage also had about 20 and 13% higher phenolics and flavonoids, respectively, compared to uninoculated RTS mango beverage. This study has shown that the RTS mango beverage inoculated with L. helveticus MTCC 5463 has potential for developing probioticated mango
