摘要: Raman spectroscopy performed using optical fibers, with excitation at 1064 nm and a dispersive detection scheme, was utilized to measure selection of unifloral honeys produced in the Italian region Calabria. The honey samples had three different botanical origins: chestnut, citrus, acacia. A multivariate processing spectroscopic data enabled us distinguish their origin, build predictive models for quantifying important nutraceutic indicators, such as main sugars potassium. Furthermore, spectra chestnut were compared taste profile measured by an electronic tongue: good correlation bitter-savory obtained. This experiment indicates excellent potential modern analytical tool nondestructive rapid multi-component analysis food quality indicators.
