Correlation between olive oil color and present pigments
Original language description
The aim of the study was finding correlation between olive oil color and present pigments. The material of the experiment consisted out of different olive oil types (n=22), including olive oil mixtures (refined olive oil + extra virgin olive oil) and extra virgin olive oils (multivarietal and monovarietal). RGB and LAB values served as parameters that described the color of olive oil samples. Following pigments were estimated in the samples of olive oil: chlorophylls, carotenoids, phenols and ?-carotene. The highest correlation between RGB parameters and pigments was observed with total carotenoid contents (-95.5%, p<0.05). Total carotenoid contents correlated highly with LAB parameters too, especially with ?b? value (yellowness) (94%, p<0.05). The study unequivocally showed high correlation between pigments in olive oil and olive oil color.
