"In this study, colorimetric indices and bioactive molecule content in nine pigmented rice samples were assessed. Colour parameters L*,a*, b* were detected by a Konica Minolta Colorimeter, while bioactive molecules such as total pigments, anthocyanin and phenolic compounds were determined by spectrophotometric methods. The main carotenoids i.e. lutein, zeaxanthin and β-carotene were detected by RP-chromatography. . A comprehensive characterization of rice samples was achieved and the relationship between colour parameters and the carotenoid content assessed.
