Martins, Rui C.; Lopes, Victor V.; Valentão, Patrícia; Carvalho, João C. M. F.; Isabel, Paulo; Amaral, Maria T.; Batista, Maria T.; Andrade, Paula B.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...
Physicochemical attributes and pollen spectrum of Portuguese heather honeys
Andrade, Paula B.; Amaral, M. Teresa; Isabel, Paulo; Carvalho, João C. M. F.; Seabra, Rosa M.; Cunha, António Proença daThe qualities of selected honey samples of "Serra da Lousã" (Portugal) from three consecutive harvests (20 samples from each harvest) were evaluated by determing the pollen spectrum and physicochemical attributes. The following determinations were carried out: moisture, electrical conductivity, hydroxymethylfurfural, diastase activity, pH, acidity (free, lactone and total), formol number, reducing sugars, appar...
