Potential use of the ATR-FTIR spectroscopy as an almond cultivar recognition to...
Lamas, Sandra; Rodrigues, Nuno; Santamaria-Echart, Arantzazu; Palu, Igor; Manhique, Jocyla; Herrero, Baudilio; Lopéz-Cortés, IsabelThree almond cultivars (Lauranne, Marinada, and Vairo) were studied, considering morphological parameters that showed statistical cultivar-dependence but not enabled accurate cultivar recognition. Alternatively, attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) was applied to whole endocarp, kernel, and ground almonds. Both transmittance spectra and respective derivatives (3400–280...

Lamas, Sandra; Rodrigues, Nuno; Santamaria-Echart, Arantzazu; Palu, Igor; Manchique, Jocyla R.; Lopéz-Cortés, Isabel; Pereira, José AlbertoAlmond's traceability is of utmost relevance.
Identification of almond’s variety based on FTIR spectra of ground samples
Lamas, Sandra; Rodrigues, Nuno; Santamaria-Echart, Arantzazu; Palu, Igor; Manchique, Jocyla R.; Lopéz-Cortés, Isabel; Pereira, José AlbertoAttenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) was employed to develop multivariate discriminant models for almond cultivar identification. For that, raw transmittance spectra were recorded for ground almonds in the range from 4000 to 500 cm-1 (Figure 1a). As can be inferred from the figure, The ATR-FTIR analysis unveiled distinct transmittance band spectral profiles, particular...
