Title:
Direct dissolution
Document Type and Number:
Japanese Patent JP6099354
Kind Code:
B2
Abstract:
The present invention describes a method for the continuous dissolution of e.g. crystalline astaxanthin or canthaxanthin suspension in oil, by applying heat for a predetermined period using an in-line or optionally batch wise-process, followed by cooling the heated solution with an oil phase or heat exchanger. The resulting oil solution may be used as such or added directly to feed components which are turned into feed compositions by extrusion, compaction or granulation. Alternatively the oil solution is spray coated or directly loaded to extruded or compacted pellets and granulates. The invention avoids using formulated carotenoids prepared by known multi-step production methods requiring solvents, solvent removal, cooling and emulsification with an aqueous phase or precipitation and recovery steps. Thus the present invention is a more economical, efficient and environmentally friendly method to add nutrients and colorants to feed compositions instead of using colloid dispersed particulate Hydrocolloid compositions.
