Karabagias, Ioannis K. published the artcileA decisive strategy for monofloral honey authentication using analysis of volatile compounds and pattern recognition techniques, Category: esters-buliding-blocks, the main research area is monofloral honey volatile compound pattern recognition.
In an effort to determine some undisputed markers of botanical origin, the volatile profile of Hellenic monofloral honeys was investigated using gas chromatog. coupled to mass spectrometry (GC-MS) in combination with headspace solid phase microextraction (HS-SPME). Different varieties of honey (citrus, fir, pine, and thyme) were analyzed and semi-quant. data of volatile compounds originating from 82 samples were subjected to multivariate anal. of variance (MANOVA). Results showed that by using only 9 volatiles [dill ether (0.012 mg kg-1), alpha-4-dimethyl-3-cyclohexene-1-acetaldehyde (0.030 mg kg-1), acetic acid Et ester (0.030-0.173 mg kg-1), octanoic acid Et ester (0.004-0.547 mg kg-1), methylanthranilate (0.030 mg kg-1), 2,2,4,6,6-pentamethyl-heptane (0.005-0.057 mg kg-1), phenylacetaldehyde (0.014-1.248 mg kg-1), cis-linalool oxide (0.007-0.010 mg kg-1), lilac aldehyde (isomer III) (0.032-0.437 mg kg-1)] honeys could be classified correctly according to botanical origin. The correct prediction rates were 93.9%, 96.8%, and 89.5%, based on the cross-validation method and using stepwise linear discriminant anal., training and holdout partitions (k-nearest neighbors anal.), resp. The efficiency of the discrimination model was confirmed further by application to mixed floral honeys and the use of the aforementioned consecutive pattern recognition techniques. The use of specific volatile compounds in combination with statistical tools may constitute a fast, decisive and accurate strategy for monofloral honey authentication.
