CAROTENOIDS IN TAGETES ERECTA L. GENETIC MODIFICATION AS AN OPTION

Abstract

Marigold (Tagetes erecta L.) is a plant native to México. Its flowers accumulate carotenoids, mostly as lutein. Flower pigments are used as food additives for poultry, fish and crustaceous feed, in order to enhance the visual attractiveness of such products for human consumption. Different studies on carotenoids and their effects on the prevention of certain ocular diseases associated with aging, such as cataracts and macular degenerative diseases, have produced interesting conclusions. These advances have promoted important advances in other areas of knowledge related to these compounds; for example, the improvement of carotenoids to be used in common products in the food industry through genetic engineering techniques.
