This short communication describes a simple chemical-based colour test for detecting fake saffron. No details are provided in the abstract about the basis of the test, or whether it discriminates botanically-related adulterants such as safflower. We have not purchased the full article in order to review it.
The abstract describes it as a panel of 4 simple chemical tests which take around 30 minutes to perform and can be read by eye from a colour card. The attached image is from a correction (open access) to the original publication (which remains behind a paywall).
