The study aimed to determine the effect of different concentrations of sodium benzoate at ambient storage condition on kokum rind juice. For this experiment, Factorial Completely Randomized Design (F.C.R.D.) was used. During the investigation, the chemical parameter, microbial analysis and sensory qualities of kokum rind juice were studied. During the 3 months of ambient storage condition, analysis was conducted at the interval of one month. The chemical parameter like acidity, TSS, reducing sugar, total sugar, anthocyanins and  microbial analysis, sensory qualities changed significantly. From the experiment it can be concluded that the kokum rind juice could be stored at 1500 ppm sodium benzoate concentration in a good acceptable condition at ambient storage condition.
