The main parameters to classify honeydew and blossom honeys were review. FT-NIR and FT-MIR spectroscopy have been proposed for the honey authentication. Melezitose and a diacylglycerilether were identified as characteristic features of honeydew honey. Spectroscopy did not allow a good determination of HMF and enzyme activities. Frauds can be avoid because honeydew and blossom honeys can be classified correctly.
