A typical carbonated soft drink comprises carbonated water sugar citric acid, flavoring, acidity regulators, coloring, preservative and artificial sweeteners.
One of the common ingredients to almost all soft drinks is the acidulant. Soft drinks have a pH range of 2.5—4.0, with colas between 2.5 and 3.1. Acidulant is the term used for nay inorganic or organic acid that contributes to the sourness of the beverage.
Because of the general tartness or sourness in taste, acidity is useful in modifying the sweetness of sugar.
The balance between sweetens and sourness is what gives it the basic typical taste profile of all flavored soft drinks.
It will increase the thirst-quenching effect of the drink by stimulating the flow of saliva in the mouth and also, because of a reduction in pH level, tends to act as a mild preservative.
Some researchers have suggested that the exposure of tooth enamel to the low pH or some soft drinks increases the risk of erosion; in addition, prolonged contact with the sugar in these drinks is a rick factor for dental caries.

What makes soft drinks so noteworthy is that, despite not being essential, their consumption continues to rise. They are entirely human inventions—both as a product and as a market. In fact, soft drinks were among the first branded goods to achieve truly global reach.
