Abstract:

The progress on Technique and Advance for Identification of products of designations of origin or geographical indications was reviewed, including in the sensory evaluation, analyzing physical and chemical index, trace element levels and determining stable isotope ratios. Special attention was given to Modern Detection Technology, such as E-nose, E-tongues, fingerprint analysis, determining trace element content and stable isotope ratios. It should be a good method for picking-up geographical characteristic, and improve abilities to identify products of designations of origin or geographical indications.
