Chemical and physical parameters of Portuguese honey: classification of Citrus, Erica, Lavandula and Eucalyptus honeys by multivariate analysis and FTIR-ATR spectroscopy (original) (raw)

In this study eight samples of monofloral honey from Portugal, selected from four different botanical origins: Eucalyptus spp., Erica spp., Lavandula spp. And Citrus spp. were studied. For each monofloral honey two samples from different producers were analysed. Several analyses were carried out: moisture content, water activity (aw). Colour, ash, pH, free acidity, electrical conductivity and total phenol content. All the data were statistically tested using variance analysis and principal component analysis (PCA) with the aim of classifying the ...
