Abstract
Aloe Vera juice is rich in vitamins, minerals, fibers, nutrients, anthraquinones, saponins,
phytosterols and salicylic acid. Its composition proves it to be an excellent source of
prebiotics and a potential substrate for probiotics. Though Aloe Vera juice has been used for
its medicinal and health benefits since ages, its value addition by converting it into a synbiotic
is lesser exploited so far. This investigation involves physicochemical, microbiological,
antioxidant and sensory evaluation of probiotic Aloe vera juice developed at the lab scale by
using Lactobacillus acidophilus MTCC 10307. The probiotic culture was inoculated to the
Aloe vera juice with initial concentration of 109-1010 CFU/ml. The probiotic viability, pH,
total soluble solids (TSS), titrable acidity, total sugars, reducing sugars, non-reducing sugars,
lactic acid content, anti-oxidant activity, vitamin C and microbial contaminations were
measured at weekly interval upto six weeks. The probiotic viability remained above 8 log
CFU/ml during the first four weeks of storage at 4°C. The total plate count, coliform count
and yeast and mould count also remained within satisfactory limits. The developed probiotic
aloe vera juice was exposed to sensory analysis by a panel of five semi trained judges on the
basis of nine-point hedonic scale. Statistical analysis showed a significant difference in taste,
texture, aroma, mouth feel of the aloe vera juice and probiotic aloe vera juice, with nonsignificant
difference in appearance, color and overall acceptability at 5% level of
significance. Though taste of probiotic aloe vera juice scored less but difference in overall
acceptability was non-significant. The sensory evaluation of aloe vera juice with and without
probiotic inoculation revealed it to be potential synbiotic product.
