Studies on the antioxidative activity of red pigments in Italian-type dry-cured ham [PDF]
, 2003 Aqueous phosphate buffer extracts and acetone/water extracts of pigments from Parma ham were assessed as antioxidants by (1) electron spin resonance spectroscopy using a spin probing technique to evaluate their efficiencies as scavengers of free radicals,

Macular pigment and its contribution to visual performance and experience
Journal of Optometry, 2010 There is now a consensus, based on histological, biochemical and spectral absorption data, that the yellow colour observed at the macula lutea is a consequence of the selective accumulation of dietary xanthophylls in the central retina of the living eye.
