NOVEL COATING SYSTEM (II)

Abstract

The present patent application relates to a novel coating system for coating solid particles, which comprise PUFAs (and/or salts thereof), wherein the coating comprises at least one protein hydrolysate. Furthermore it relates to compositions coated with such a coating system and the use of such compositions in the production of food, feed, dietary supplements and/or pharmaceutical products.

Claims

1. A coating system comprising at least 10 wt-%, based on the total weight of the coating system, of at least one protein hydrolysate.

2. A coated composition comprising (a) a core, which is a sold formulation comprises at least one PUFA (and/or salts thereof) and (b) a coating system according to claim 1.

3. The coated composition according to claim 2, comprising (a) 70 to 99.5 wt-%, based on the total weight of the composition, of core and (b) 0.5 to 30 wt-%, based on the total weight of the composition, of coating system.

4. Process of production of a coated composition according to claim 2, wherein (i) the cores (which comprise PUFA (and/or salts thereof) are produced by beadlet process, spray drying or spray-granulation in a first step. (ii) these cores (solid particles) are coating in a second step by a solution, dispersion or slurry of the coating material (hydrolysate), and (iii) afterwards the coated particles are dried.

5. Use of the coated particles according to claim 2 in food products, feed products, dietary supplements and/or pharmaceutical products.

6. Food products, feed products, dietary supplements and/or pharmaceutical products, comprising at least one coated composition according to claim 2.

Description

EXAMPLE 1

[0064] An aqueous solution containing 5.5 wt-% of whey protein hydrolysate is produced by dissolving/dispersing whey protein hydrolysate in water.

[0065] 150 g beadlets containing ca 400 mg/g PUFA (mainly DHA and EPA) are fluidized in a lab-scale fluid-bed processor using Wurster technology. The whey protein hydrolysate solution is sprayed on the fluidized particles at a product temperature of 55-64 C. After spraying, the product is dried in the processor at 49-59 C., A free flowing powder of coated beadlets is obtained. The product has a neutral smell, no fishy or rancid smell can be observed.
