Volatile components of Zalema white wines
TL;DR: The volatile composition of young white wines from Vitis vinifera cv. Zalema, an autochthonous grape variety in Huelva (southern Spain), has been studied by gas chromatography-olfactometry (GC-O) and techniques of quantitative analysis.
Journal ArticleDOI
Multivariate Correlation between Color and Mineral Composition of Honeys and by Their Botanical Origin
M.L. González-Miret,Anass Terrab,Dolores Hernanz,Maria Angeles Fernandez-Recamales,Francisco J. Heredia +4 more
TL;DR: The results obtained shown that lightness (L) was significantly correlated with S, Ca, Fe, As, Pb, and Cd for the dark honey types (avocado, heather, chestnut, and honeydew).
Journal ArticleDOI
Characterisation of Spanish thyme honeys by their physicochemical characteristics and mineral contents
TL;DR: In this paper, the qualities of 25 thyme honey samples from Spain were evaluated, including water content, pH, acidity (free, lactonic and total), sugar content, ash, electrical conductivity and mineral composition, including potassium (K), sodium (Na), calcium (Ca), magnesium (Mg), phosphorus (P) and sulphur (S).

Chromatic characterization of anthocyanins from red grapes—I. pH effect
Francisco J. Heredia,E. M. Francia-Aricha,Julián C. Rivas-Gonzalo,Isabel M. Vicario,Celestino Santos-Buelga +4 more
TL;DR: In this paper, five anthocyanins (the 3-monoglucoside of delphinidin, cyanidin and petunidin), isolated from red grape skins, were subjected to a spectroscopic study to characterize their chromatic properties in a model solution imitating wine in the pH range 1.5-7.0.
Journal ArticleDOI
Relationship between the colour and the chemical structure of carotenoid pigments
TL;DR: In this paper, carotenoids were isolated and their colours were ascertained objectively to establish relationships between the chemical structures of those pigments and their actual colours, considering the coordinates of the uniform space CIELAB.
