Abstract: Stable vitamin A powders The present invention relates to BHT-free powderous formulations comprising a fat-soluble-vitamin or a carotenoid, a hydrocolloid, a starch hydrolysate, tocopherol and sodium ascorbate and its use for staple food fortification.

Abstract: The present invention relates to astaxanthin compositions for use in foodstuffs, food supplements or feedstuffs or as a medicament. Astaxanthin compositions which comprise up to at least 50% by weight, in particular at least 60% by weight, particularly at least 70% by weight, specifically at least 80% by weight or at least 90% by weight, based on the total weight of astaxanthin and astaxanthin derivatives in the composition, of an astaxanthin monoester with an aliphatic, unbranched C10C22-monocarboxylic acid have a particularly good bioavailability when at least 90% by weight of the monoester present in the astaxanthin composition is a monoester with precisely one aliphatic, unbranched C10-C22-monocarboxylic acid. They are therefore particularly suitable for the use in foodstuffs, food supplements or feedstuffs and for the therapeutic use as medicament and as constituent for medicinal preparations and pharmaceutical compositions.

Abstract: The present invention relates to astaxanthin compositions for use in foodstuffs, food supplements or feedstuffs or as a medicament. Astaxanthin compositions which comprise at least 50% by weight, in particular at least 60% by weight, especially preferably at least 70% by weight and specifically at least 80% by weight or at least 90% by weight, based on the total weight of astaxanthin and astaxanthin derivatives in the composition, of an astaxanthin monoester with a C18-1 fatty acid have a particularly good bioavailability. They are therefore particularly suitable for use in foodstuffs, food supplements or feedstuffs and for the therapeutic use as medicament and as constituent for medicinal preparations and pharmaceutical compositions.

Abstract: The present invention relates to a liquid formulation containing at least one carotenoid, at least one hydrophilic protective colloid and at least one water-miscible alcohol. The formulation according to the invention can be added directly to aqueous or non-aqueous preparations. The invention compositions can be used in animal feed, human food or a dietary supplement and in pharmaceutical and cosmetic preparations.

Abstract: The present invention relates to unctuous composition containing at least one solid active ingredient, at least one hydrophobic protective colloid and at least one edible oil. The active ingredient is preferably a carotenoid. The preferred protective colloids are prolamines. The invention compositions are simple to produce, have good bioavailability and dyestuff yield, and are used an addition to animal feed agents, foods, and dietary supplements and pharmaceutical and cosmetic agents.

Abstract: Aqueous suspensions comprising: (a) at least one sparingly water-soluble or water-insoluble active agent in the form of nanoparticulate particles; (b) at least one whey component selected from the group consisting of whey proteins, whey protein hydrolysates, and mixtures thereof; and (c) at least one sucrose fatty acid ester having an HLB value of 10 to 18; processes for preparing such aqueous suspensions; powders and oil-miscible compositions prepared therefrom and uses therefore.

Abstract: The present invention relates to aqueous dispersions comprising at least one slightly water-soluble or water-insoluble active compound and at least one protein as protective colloid, wherein the protein is a single cell protein material produced by fermentation.

Abstract: The invention relates to a method for producing dry powders of one or several carotenoids, said method being characterised in that a) one or several carotenoids are suspended in an aqueous molecularly dispersed or colloidally dispersed solution of a mixture consisting of trehalose and at least one protein-containing protective colloid and b) the obtained suspension is transformed into a dry powder by separation of water and, optionally, additionally used solvents and by subsequent drying, optionally in the presence of a coating material.
