Total Soluble Solids (TSS)

As there is no approved method to determine the fruit content in fruit juice/drink in the laboratory, we tested the TSS percentage of the mango drink samples. TSS is the measure of sugar content of juice/ drink, both natural and added. TSS is considered as higher the better, subject to it being low in added sugar and restricted quantity of other thickening agents.

As per Food Safety and Standards (Food Products Standards and Food Additives) Regulations, 2011, the total soluble solids (mass/mass) in mango drink should not be less than 10 per cent.

  • All the brands met the minimum requirement.
  • Paper Boat (16.22 per cent) had the highest quantity of TSS, which, as stated earlier, is beneficial for consumers. Jumpin (12.13 per cent) had the lowest quantity of TSS.
  • Total titrable acidity (as citric acid, grams/100

    Total titrable acidity is the total amount of acid in the juice/drink. Acidity improves the taste and increases the shelf life of the product but excessive acidity may also spoil the taste of the juice/drink. Acidity in the drink should be optimum with respect to total soluble solids. There is no specification for acidity in the FSS Regulations.

  • Paper Boat (0.35 grams/100 ml) was found with the highest amount of citric acid; Jumpin (0.19 grams/100 ml) had the least amount of citric acid.
  • Flat Sour Organisms (Bacteria)

    Food spoiled by flat sour organisms will produce a sour smell and taste. As per Food Safety and Standards (Food Products Standards and Food Additives) Regulations, 2011, the flat sour organisms should not be more than 10,000 colony-forming units (cfu)/gram for products that have pH less than 5.2 (pH indicates the strength of the acid condition).

  • All the brands passed the legal requirement. Hence they are safe for human consumption.

  • For General Qualities

    Packaging
