With the aim of finding methods that could constitute a solid alternative to melissopalynological andphysicochemical analyses to determine the botanical origin (floral or honeydew) of honeys, the freeamino acid content of 46 honey samples has been determined. The honeys were collected in a smallgeographic area of ~2000 km² in central Spain. Twenty-seven honey samples were classified asfloral and 19 as honeydew according to their palynological and physicochemical analyses. The resultingdata have been subjected to different multivariant analysis techniques. One hundred percent of honeysamples have been correctly classified into either the floral or the honeydew groups, according totheir content in glutamic acid and tryptophan. It is concluded that free amino acids are good indicatorsof the botanical origin of honeys, saving time compared with more tedious analyses.Keywords: Floral honey; honeydew honey; free amino acids
