The appearance of most of the commercialized olive oils involves both their color and turbidity depending on the different technologies used for their elaboration. This research has been carried out to study the filtration impact on the colorimetric changes of virgin olive oils. Naturally turbid olive oils were blended at different proportions...

Se ha estudiado la utilidad de la nefelometría espectral en la medida simultánea del color y turbidez en aceites de oliva virgen extra. Se han considerado 25 aceites, cada uno de ellos con 6 niveles de turbidez diferente, sobre los que se han realizado medidas nefelométricas y gonioespectrofotométricas (0º, 30º, 60º y 90º). Los resultados ponen...

This paper presents an experiment making use of the near-infrared spectrum for distinguishing the wines produced in two close provinces of Abruzzo region of Italy. A collection of 32 wines was considered, 18 of which were produced in the province of Chieti, while the other 14 were from the province of Teramo. A conventional...

Overripe seeds from sun-dried grapes submitted to postharvest dehydration constitute a scarcely investigated class of vinification byproduct with limited reports on their phenolic composition and industrial applications. In this study, Raman spectroscopy was applied to characterize a selection of overripe seed byproducts from different white...
