Which gas is present in Limca?
The carbon dioxide gas is dissolved in water to form carbonic acid which is also responsible for the tangy taste. Carbohydrates are the naturally occurring organic compounds and are major source of energy to our body….Determination of Contents of Cold Drinks.

How much preservative is in a drink?
Multiply the weight of your product by the usage rate percentage, and divide that number by 100. So, if your concoction weighs 50g and the usage rate is 2.5%, that would be 50 × 2.5 = 125. 125 ÷ 100 = 1.25. That means you should add 1.25g preservative to your concoction.
