چکیده انگلیسی
This paper describes an isotope control method designed to identify the origin of CO2 in sparkling bottled waters. The method is based on the analysis of the 13C/12C ratio in the dissolved inorganic carbon (DIC) of carbonated bottled water. Natural carbonated natural water has δ13CPDB (DIC) values between â8â° and +7â°. Generally, the industrial carbon dioxide injected into mineral bottled water is produced from hydrocarbons by burning or chemical processing. Hydrocarbons, and their derived CO2, are characterised by a low 13C/12C ratio. Thus, a single analysis distinguishes the carbon dioxide in the bottled water (i.e. either from a natural source or added exogenous CO2 of industrial origin). Rarely, CO2 can be obtained from other industrial sources, mainly as a by-product of fermentation plants. Nevertheless, the carbon isotope fingerprint allows detection of the industrial gas injected in most of these cases.
