Abstract
Lutein and zeaxanthin, the main carotenoids in marigold flowers, and capsanthin and capsorubin, the main carotenoids in red peppers are esterified mainly with C-18 fatty acids. The pigments were re-esterified without isolating them from the natural saponified extract using carboxylic acids in the range of C-1 to C-12 and their corresponding metallic salts in the presence of a catalyzing agent. Both the diester and monoester forms were obtained. It is expected that the pigment esters with a fatty acid of 12 or less carbons will have a better digestibility than the esters of xanthophylls in their natural state and better stability than the hydrolyzed xanthophylls. This will result in a better pigmentation capacity of the carotenoids for poultry or aquaculture.
