Abstract
Method for isotopic identification, allowing, where appropriate, a liquid to be linked to a site of growth or harvest or a sub-product derived from a determined liquid, via analysis of concentration or of ratios of stable isotopes, and comparison to isotopic codes generated beforehand in a manner unique to a set of liquids issued from a site of growth, harvest or conversion. The invention also relates to a method that makes it possible to give a unique code to liquids of a site of growth, harvest or conversion, and to a computer making it possible to store the unique codes generated in memory, to generate unique codes for new liquids of a site of growth, harvest or conversion and to perform comparisons.
