Definitions
- the present invention refers to a new methodology for obtaining formulations of lutein, mainly esters of lutein with various fatty acids, from any natural or synthetic source, which provide a high added value to these molecules, since they allow to obtain stabilized preparations of them of direct application in the food, pharmaceutical and cosmetic fields.
- carotenoids have been considered as plant pigments. In fact they are found in all green tissues in the form of photosynthetic pigment-protein complexes within chloroplasts. However, the typical yellow to red color of the carotenoids is masked by the green color of the chlorophylls, being able to observe the typical coloration provided by the carotenoids in the leaves of many trees in autumn, when the chlorophyll breaks down, and the xanthophylls are esterified with mixtures of fatty acids. With few exceptions, the carotenoids present in the vast majority of the leaves of all species are ⁇ , ⁇ -carotene, lutein, violaxanthin and neoxanthin.
- carotenoids such as ⁇ , ⁇ -carotene, ⁇ -cryptoxanthin, zeaxanthin, antheraxanthin, 5,6-lutein epoxide and lactucaxanthin can also be found.
- SUBSTITUTE SHEET (RULE 26) Many flowers or fruits (tomato, orange, pepper, marigold, 7), which have a color fan between yellow and red, owe their coloring to the carotenoids located in the chromoplasts thereof, and often present in esterified form with fatty acids (G. Britton, S. Liaaen-Jensen, H. Pfander, Carotenoids, Volume 1A: Isolation and Analysis, 201, Ed. Birkhauser, 1995).
- Carotenoids can be divided into two classes: pure hydrocarbons, called carotenes, which include compounds such as ⁇ -carotene, ⁇ -carotene, ⁇ -carotene or lycopene and xanthophylls, molecules that contain oxygenated functions, examples of this type being asthaxanthin, capsantin, cantaxanthin o- lutein. Both groups of compounds have a different behavior in terms of their physicochemical properties and solubility in organic solvents.
- Lutein, (3R, 3'R, 6 'R) - ⁇ , ⁇ -carotene-3, 3'-diol is a carotenoid that belongs to the group of xanthophylls or carotenoids with oxygenated functions. It is an asymmetric polyunsaturated molecule consisting of a carbon skeleton similar to that of ⁇ -carotene ((6'R) - ⁇ , ⁇ -
