Characterization of the principal colouring components of annatto using high performance liquid chromatography with photodiode-array detection
Characterization of the principal colouring components of annatto using high performance liquid chromatography with photodiode-array detection
- Food Additives and Contaminants, 11(3), p.301-315, 1994 .
The principal colouring components of the natural food colouring material annatto, the 9'-cis- and all-trans- isomers of bixin and norbixin, have been prepared in pure form. A reverse-phase HPLC method utilizing photodiode-array detection has been developed to enable their Chromatographic and spectroscopic characterization. One minor component, a di-cis-isomer of norbixin has also been identified and characterized. © 1994, Taylor & Francis Group, LLC. All Rights Reserved.
