Powderous formulation

Abstract

The present invention relates to a powderous formulation comprising powder particles. These powder particles do comprise polyunsaturated oils, especially polyunsaturated fatty acids, and the powder do have at the same time an excellent sensory profile, a fine particle structure and a high oil loading.

Claims

1. A powderous formulation comprising: (i) powder particles formed of a supercritical CO.sub.2-dried emulsion; and (ii) gas cells in the powder particles which comprise CO.sub.2 gas, wherein the supercritical CO.sub.2-dried particulate emulsion comprises: (a) at least one polyunsaturated oil selected from the group consisting of eicosapentaenoic acid (EPA), arachidonic acid (ARA), docosahexaenoic acid (DHA) and docosapentaenoic acid (DPA), (b) at least one emulsifier, (c) at least one carbohydrate with no emulsifying properties, and (d) optionally at least auxiliary agent, and wherein the powder particles have a size in a range of 100 - 600 nm, and the gas cells have a size such that a size ratio of the gas cells to the powder particles is at least 1:100.

2. The powderous formulation according to claim 1, wherein the emulsifier is at least one selected from the group consisting of carbohydrate, mono-polysaccharides, di-polysaccharides, oligo-polysaccharides and modified food starch.

3. The powderous formulation according to claim 1, wherein the auxiliary agent is at least one selected from the group consisting of antioxidants, antimicrobials, pH-buffers, chelating agents, dyes and fillers.

4. The powderous formulation according to according to claim 1, wherein the supercritical CO.sub.2-dried emulsion comprises: (a) 5 - 60 wt-%, based on the total amount of the powder particles, of the at least one polyunsaturated oil, and (b) 2 - 45 wt-%, based on the total amount of the powder particles, of the at least one emulsifier, and (c) 5 - 55 wt-%, based on the total amount of the powder particles, of the at least one carbohydrate with no emulsifying properties, and (d) up to 20 wt-%, based on the total amount of the powder particles, of the at least auxiliary agent.

5. Food products, feed products and/or personal care products comprising the powderous formulation according to claim 1.
