For genetic improvement in the active component of marigold flower seeds (xantofilas). The Group has enhanced its active components (carotenoids) using these seeds for more than 170% and has become a leading producer worldwide. Inca Health is proud to have the first seed patent pending in Peru No. 001.
Lutein and zeaxanthin are carotenoid that is selectively taken up into the macula of the eye where they are thought to protect against the development of the age-related macular degeneration. Current dietary databases make it difficult to ascertain their individual roles in eye health because their concentrations in foods are generally reported together. The objective of this work is to determine the concentration of lutein and zeaxanthin, separately, within major food sources of dietary xanthophylls as determined by NHANES 2001-2002 intakes. Corn and corn products were found to be major contributions of dietary zeaxanthin whereas green leafy vegetables were major contributors of dietary lutein. The predominant isomeric xanthophyll form was trans for all foods. Processed foods contained more cis xanthophyll isomers than fruits and vegetables. Their data will provide added information to the current databases for lutein and zeaxanthin content of commonly consumed foods as well as enhances the validity of estimates of dietary intake of these xanthophyll.
