Problems solved by technology

The main disadvantage of these techniques is that relatively low viscosity is required (usually below 1 Pas), resulting in a large amount of water in the dispersion

Embodiment approach

[0143] 1. Process for producing discrete solid extruded particles, wherein in a first step an extrudate comprising droplets of a solid-in-water lipophilic active dispersion is produced by extrusion, wherein said dispersion comprises at least one carotenoid and at least one emulsifying protective colloid and water,

[0144] And after extrusion, the extrudate is further formed into discrete solid extruded particles.

[0145] 2. The method according to embodiment 1, wherein the dispersion process is carried out in an extruder.

[0146] 3. The method according to embodiment 1 or 2, wherein the extrudate is further formed into discrete solid particles by cutting and drying.

[0147] 4. The method according to embodiment 3, wherein drying can be performed before cutting, during cutting or after cutting and any combination (sequence) thereof.

[0148] 5. The method according to embodiment 1 or 2, wherein said extrudate is further formed into said discrete solid extruded particles b...

Embodiment 1

[0186] Example 1 : Dispersion of β-Carotene in Modified Food Starches

[0187] Extrusion dispersion of β-carotene in 10.5 g of modified food starch was carried out in a laboratory scale conical twin-screw (batch) extruder (DSM Xplore 15 ml micro-synthesizer). 10.5g modified food starch (HICAP 100, National Starch) was mixed with 0.75g β-carotene (DSM Nutritional Products) and 3.75g demineralized water. The extruder was operated at a screw speed of 120 rpm and a barrel temperature of 200°C. The feed hopper and extruder were purged with nitrogen. The mixture was placed in the feed hopper, passed through the extruder once and exited through the 1 mm die.

[0188] The extrudate chains obtained were partially dissolved in water, resulting in an orange cloudy solution which was stable for more than 12 hours. Filter this solution with pleated filter paper (5971 / 2: 5–7 μm grade) or a syringe driven filter element (0.22 μm). Filtration with larger pores resulted in a cloudy light ...

Abstract

The present invention relates to a process for the production of discrete solid extruded particles comprising dispersion droplets, to such particles as well as to the use of such particles in food, feed, pharmaceutical and personal care applications.

Description

[0001] This application is a divisional application of Chinese Invention Patent Application 201380061322.0 (corresponding to PCT / EP2013 / 074885) with the filing date of November 27, 2013 and titled "Method for Producing Discrete Solid Extruded Particles". technical field [0002] The present invention relates to particles for food, feed, medicine or personal care and methods for their manufacture. In particular, the present invention relates to a method of producing discrete solid extruded particles comprising dispersion droplets, said particles and the use of said particles in food, feed, pharmaceutical and personal care applications . Background technique [0003] There are many methods of formulating carotenoids. The type of formulation depends on, ie, the use of these formulations in the end use and the kind of materials (ingredients) used. However, the most important and required formulations are so-called dry dispersions. The carotenoids are emulsified into an aqueou...
