Effect of storage conditions and benzoic acid concentrations on chemical composition and shelf life of aonla juice Cv. NA-10

Abstract

The present study entitled, “Effect of Storage Conditions and Benzoic Acid Concentrations on Chemical Composition and Shelf life of Aonla Juice Cv. NA-10” was undertaken with 4 concentrations of benzoic acid (0, 200, 400, 600 ppm) and 2 storage conditions (ambient and cold storage). Among different benzoic acid concentration tried, treatment T4 (600 ppm benzoic acid) recorded maximum T.S.S, reducing sugars, total sugars, pH, ascorbic acid and minimum acidity content at the end of storage (6 month). Hence, for storage of aonla juice treatment T4 was found to be good. In case of storage condition, cold storage (S2) was found to be good as it recorded increase in T.S.S, reducing sugars, total sugars, pH and decrease in acidity up to 6 months, as compared to ambient temperature and minimum decrease in ascorbic acid throughout storage period as compared to ambient temperature. In case of shelf life, among different benzoic acid concentrations tried, treatment T4 (600 ppm) and in case of storage conditions, cold storage (S2) was found to be good. Hence, for better storage of aonla juice upto 6 months, interaction T4S2 (600 ppm benzoic acid and cold storage) was found to be good.
