Problems solved by technology

[0003] However, due to the conjugated polyene structure of lutein, its chemical stability is poor, and it is easily degraded by oxygen, light, temperature, etc., making it lose its biological activity, which affects the storage and transportation of lutein; , Lutein is insoluble in water, slightly soluble in oil and fat
The above factors greatly limit the scope of application of lutein
[0004] U.S. Patent No. 6,863,914 discloses a preparation method of a stable water dispersion of lutein substances and a stable water-dispersible dry powder. The method dissolves lutein in a mixed solution of an organic solvent and water, so the method has an organic solvent Residual problems, not suitable for use in food and pharmaceutical industries
Chinese patent 200610049837 discloses a lutein microcapsule and its preparation method. The preparation method of the microcapsule is complicated and the raw material cost is high

Abstract

The invention discloses high-inoxidizability lutein microcapsules.The microcapsules are prepared from a core material, a wall material, an auxiliary material and an antioxidant, the core material is a combination of lutein crystals and sunflower seed oil, the wall material is one of or a mixture of starch sodium octenyl succinate, gelatin and Arabic gum, the auxiliary wall material is one of or a mixture of sucrose stearate, sodium caseinate, lactose and sucrose, the antioxidant is one of or a mixture of L-ascorbyl palmitate, L-sodium ascorbate and lecithin, and a mass ratio of the core material, the wall material, the auxiliary wall material and the antioxidant is 5-30:20-60:10-40:0.3-3.The invention further discloses a preparation method of the microcapsules.Spray granulation and cold air boiling drying technologies are improved, and yield of the microcapsules is obviously increased while waste of raw materials is reduced.By using the preparation method, oxidization stability of the lutein microcapsules can be improved greatly, so that shelf life of the microcapsules is prolonged.

Description

technical field [0001] The invention relates to a preparation and a preparation method thereof, belonging to the technical field of pharmaceutical preparations. Background technique [0002] Lutein, also known as "plant lutein", is an oxygen-containing carotenoid without vitamin A activity, which is widely found in plants such as bananas, kiwis, corns and marigolds. Lutein is a natural coloring agent, which has the advantages of bright color, strong coloring power, safety and non-toxicity. At the same time, lutein has obvious biological effects such as anti-oxidation, anti-aging and anti-mutation. In particular, it shows a strong effect on vision protection, and can prevent macular degeneration and senile cataract. Lutein has been widely used in food, health products, medicine, animal feed and other fields. [0003] However, due to the conjugated polyene structure of lutein, its chemical stability is poor, and it is easily degraded by oxygen, light, temperature, etc., mak...
