Relevant principal component analysis applied to the characterisation of Portuguese heather honey
The main purpose of this study was the characterisation of ‘Serra da Lousã’
heather honey by using novel statistical methodology, relevant principal
component analysis, in order to assess the correlations between production
year, locality and composition. Herein, we also report its chemical composition in
terms of sugars, glycerol and ethanol, and physicochemical parameters. Sugars
profiles from ‘Serra da Lousã’ heather and ‘Terra Quente de Tra´ s-os-Montes’
lavender honeys were compared and allowed the discrimination: ‘Serra da Lousã’
honeys do not contain sucrose, generally exhibit lower contents of turanose,
trehalose and maltose and higher contents of fructose and glucose. Different
localities from ‘Serra da Lousã ’ provided groups of samples with high and low
glycerol contents. Glycerol and ethanol contents were revealed to be independent
of the sugars profiles. These data and statistical models can be very useful in the
comparison and detection of adulterations during the quality control analysis of
‘Serra da Lousã’ honey
