Carbon dioxide’s role in the carbonated drinks
Food grade CO2, which is special for sparking wine and carbonated drink, mainly comes from fermentation or chemicals industries at present.
Co2 from chemical reaction is another selection for customers from developing countries. This chemical reaction is based on NaHCO3(Sodium Bicarbonate) and H2SO4(Sulfate).
Following is reaction equation:
CO2 from this reaction is not pure gas, because acid must mixed there. It should be purified by several filters again before being used in beverage production.
