Definitions
- the invention relates to a lutein concentrate and a process for its preparation.
- Xanthophyll lutein is a natural dye that is also approved and usable in the food sector. It occurs in many plants and algae (for example Dunaliella salina) and can be obtained therefrom in its esterified form, for example as palmitate or myristate, in the manner described in US Pat. No. 6,191,293. The lutein ester is often mixed with a small amount of zeaxanthin ester.
- lutein preparations are often recommended as a component of food supplements.
- the use of compositions containing lutein is complicated by the fact that lutein and its esters are practically water-insoluble and therefore only in oily form
- Suspension can be processed. Therefore, the amount of lutein that can actually be used by the organism is very low.
- the invention has for its object to improve the bioavailability of lutein or its ester-containing compositions and their processability.
- a lutein solubilizate is used for this purpose, which consists of one part of a composition containing lutein and about 7 to about 9 parts of a polysorbate, advantageously polysorbate 80.
- a polysorbate advantageously polysorbate 80.
- Solubilisate consisting of from about 3% to about 15% by weight of the composition and from about 75% to about 85% by weight of the polysorbate. Further advantageous embodiments are specified in the subclaims.
- the solubilizate which contains about 1% to about 3% pure lutein, has a dark red color and is readily soluble in water at room or body temperature or, if appropriate, at a slightly elevated temperature.
- the solubilisate's water solubility not only facilitates its processing as
- the lutein In the aqueous solution of the lutein concentrate, the lutein is present in a micellated form with a micelle size of approximately 50 nm to approximately 100 nm.
- the preparation of the concentrate is simplified.
- the polysorbate is particularly advantageously composed of polysorbate 80.
- Polysorbate 20 can also be used to obtain inexpensive solubilizates with the same properties as when using polysorbate 80.
- the method according to the invention for the production of the solubilizate provides that a composition containing lutein is stirred with about seven to about nine times the polysorbate, if appropriate in mild heat.
- the solubilizate according to the invention can be processed particularly simply in such a way that it is heated to at least 45 ° C., advantageously approx. 70 to approx. 80 ° C., and stirred with appropriately heated water. Two parts of water are added to one part of solubilisate.
- solubilizate liquid 35% and a total zeaxanthin content of at most about 7% are mixed with 117.5 g of water and the mixture is heated to 45 ° C.
- 750 g of polysorbate 80 are mixed with 100 g of a medium-chain triglyceride fat (source: CAESAR & LORETZ GmbH, Hilden, product: MIGLYOL 812) and heated to about 60 ° C. Both mixtures are combined and heated to a total of 90 ° C and always stirred. After cooling to room or body temperature, a dark red, solid, water-soluble solubilizate results. Heating the same to about 45 ° C makes the solubilizate liquid.
- the solubilizate described above has a total lutein equivalent concentration of about 1%.
- solubilisates prepared according to Example 3, can be diluted with tempered water for ease of processing or incorporation into the end product, preferably to the extent that a 1% lutein solubilisate is obtained.
- solubilizate which was previously heated to approx. 45 ° C, is mixed with a ratio of 1: 2 with water at the same temperature. It should be noted that the 3% solubilisate is added to the water and stirred and not in the reverse order.
