- Comparison of FT-Raman and FT-NIR spectroscopy for distinguishing between two honey PDOsPublication . Pedro, Soraia; Ferreira, Ana; Catarro, Gonçalo; Gallardo, Eugenia; Peres, Maria de Fátima; Anjos, OféliaVibrational spectroscopy has demonstrated high applicability for honey analysis, offering rapid, non-destructive and accurate methods for assessing its chemical composition, identifying different honey regions and ensuring authenticity. In this study, we compare the usefulness of FT-Raman and FT-NIR spectroscopy techniques in distinguishing between two Protected Designation of Origin (PDO) of honey, name quality, determined according to the standard methods of the International Honey Commission including acidity, pH, moisture, water activity (aw), electrical conductivity (EC), total polyphenols (TPC), total flavonoid content (TFC), and CIELAB color (L*, a*, b*), as well as the color in PFUND scale. The values observed for the analytical parameters are all in accordance with legal limits.
- Differentiation of honey produced in two PDO regions in Portugal using FTIRT-ATR analysisPublication . Pedro, Soraia; Ferreira, Ana; Gouveia, Cecília; Gallardo, Eugenia; Rodrigues, A.M.; Peres, Maria de Fátima; Anjos, O.The chemical composition of honey in a Protected Designation of Origin (PDO) reflectes the unique characteristics of the region, ensuring authenticity through rigorous standards. To identify the consistent analytical parameters within a particular PDO and assess the possibility of distinguishing them using rapid techniques, such as FTIR-ATF (Fourier Transform Infrared Spectroscopy with Attenuated Total Reflectance).
