of carbonated water
Carbonated water contains no calories, sugar, or significant nutrients, consisting essentially of water and carbon dioxide. The carbonation itself does not alter the nutritional profile of the underlying water source.
About
Carbonated water is water that has been infused with carbon dioxide (CO₂) gas under pressure, creating the characteristic effervescence and slight acidity. The carbonation process involves dissolving CO₂ into water at temperatures between 0–4°C and pressures of 3–4 atmospheres, which produces carbonic acid (H₂CO₃) with a pH typically between 3.5 and 4.0. Plain carbonated water contains no added sugars, flavors, or minerals beyond those naturally present in the source water, distinguishing it from flavored sodas and mineral waters. The mouthfeel is distinctly tingling and sharp, with a subtle acidic bite.
Culinary Uses
Carbonated water functions both as a beverage and as a culinary ingredient in cooking and baking. In the kitchen, it is used to create light, airy batters for tempura, pancakes, and cakes due to CO₂ bubbles providing lift without chemical leaveners. It appears in cocktails and mocktails as a mixer and palate cleanser. Carbonated water is also employed in sorbets and granitas to enhance texture and create a refreshing crumb structure. In savory applications, it is occasionally used in doughs and marinades, where its acidity and effervescence may tenderize proteins or contribute subtle flavor complexity.
