Definitions
- the invention relates to a process for the preparation of dry powders of one or more carotenoids, preferably xanthophyll-containing dry powders, in particular xanthophylls, selected from the group consisting of astaxanthin, canthaxanthin, lutein, zeaxanthin, citranaxanthin and ⁇ -apo-8'-carotenic acid - ethyl ester.
- xanthophyll-containing dry powders in particular xanthophylls, selected from the group consisting of astaxanthin, canthaxanthin, lutein, zeaxanthin, citranaxanthin and ⁇ -apo-8'-carotenic acid - ethyl ester.
- the class of carotenoids is classified into two main groups, the carotenes and the xanthophylls.
- the carotenes which are pure polyene hydrocarbons, such as, for example, ⁇ -carotene or lycopene
- oxygen functions such as hydroxyl, epoxy and / or carbonyl groups also occur in the xanthophylls.
- Typical representatives of this group include Astaxanthin, canthaxanthin, lutein and zeaxanthin.
- the oxygen-containing carotenoids also include citranaxanthin and ß-apo-8'-carotenic acid ethyl ester.
- Oxygenated carotenoids are widespread in nature and include in corn (zeaxanthin), in green beans (lutein), in peppers (capsanthin), in egg yolks (lutein) as well as in crayfish and salmon (astaxanthin), giving these foods their characteristic color.
- polyenes which are both synthetically accessible and isolable from natural sources, represent important color bodies for the food and animal feed industries and for the pharmaceutical sector and, as in the case of astaxanthin, are active ingredients with provitamin A activity in salmon.
- finely divided, powdered carotenoid preparations are prepared by dissolving a carotenoid in a volatile, water-miscible organic solvent at elevated temperatures, optionally under increased pressure, by mixing the carotenoid with a precipitates aqueous solution of a protective colloid and then spray dried.
- aqueous, xanthophyll-containing active ingredient dispersions are often colloidally unstable, particularly when concentrated. Due to flocculation of the active ingredient particles, which partially sediment, partially cream, a further transfer of the dispersion into a dry powder is no longer possible.
- gelatins Another disadvantage of gelatins is their strong adhesive properties. With the usual drying methods for liquid systems such as spray drying, it can when using gelatin-containing products, thread formation or caking occur.
- Synthetic colloids such as polyvinylpyrrolidone or partially synthetic polymers such as cellulose derivatives also have a limited emulsifying capacity and are not always accepted, especially in the food sector.
- DE-A-44 24 085 describes the use of partially degraded soy proteins as protective colloids for fat-soluble active ingredients.
- the soy proteins disclosed here have a degree of degradation of 0.1 to 5%.
- the color strength of the formulations produced using these protective colloids is not always satisfactory.
- German Offenlegungsschrift DE-A-101 04494 describes the production of carotenoid dry powders using soy proteins together with lactose as protective colloids. Despite improved cold water redispersibility and increased coloring power of the carotenoid preparations disclosed here, the storage stability of these formulations, especially when the active ingredient content is high, is not always satisfactory.
- the object of the present invention was therefore to propose processes for the preparation of carotenoid-containing dry powders, in particular dry powders of oxygen-containing carotenoids, which do not have the above-mentioned disadvantages of the prior art and which enable a high carotenoid content in the preparation to achieve.
- Gelatin for example pork or fish gelatin, in particular acidic or basic degraded gelatin with Bloom numbers in the range from 0 to 250, very particularly preferably gelatin A 100 and A 200, and low molecular weight, enzymatically degraded gelatin types with the Bloom number 0 and molecular weights of 15,000 up to 25,000 D such as Collagel A and Gelitasol P (Stoess, Eberbach) and mixtures of these types of gelatin;
- Casein and / or a caseinate for example sodium caseinate
- Plant proteins such as soybean, rice and / or wheat proteins, these plant proteins being partially degraded or in undegraded form.
- Casein or a caseinate or mixtures thereof are used as preferred protective colloids in the context of the present invention.
- Sodium caseinate is a particularly preferred protective colloid.
- the process is characterized in that the suspension produced in process step a) is ground into a dry powder before being transferred.
- the active ingredient [the carotenoid (s)] is preferably suspended in crystalline form before the grinding process.
- the grinding can be carried out in a manner known per se, e.g. done with a ball mill. Depending on the type of mill used, grinding is carried out until the particles have an average particle size D [4.3], determined via Fraunhofer diffraction, of 0.1 to 100 ⁇ m, preferably 0.2 to 50 ⁇ m, particularly preferably 0.2 to 20 ⁇ m , very particularly preferably 0.2 to ⁇ m, in particular 0.2 to 0.8 microns.

- a likewise preferred variant of the method according to the invention is characterized in that the suspension in stage a) contains the following steps: ai) dissolving one or more carotenoids in a water-miscible organic solvent or in a mixture of water and a water-miscible organic solvent or
