Abstract

The invention discloses a lutein ester microcapsule preparation and as well as a preparation method and a use thereof. The lutein ester microcapsule preparation is prepared from the following raw materials in parts by weight: 1 part of lutein ester, 8-11 parts of wall material, 0.001-0.03 parts of water-soluble emulsifier, 0.2-0.35 parts of water-soluble antioxidant, 0.1-0.3 parts of oil-soluble antioxidant, 2-3 parts of inulin and 20-40 parts of purified water. The preparation method comprises the following steps: adding the wall material, the water-soluble emulsifier and the water-soluble antioxidant into the purified water, mixing to dissolve so as to obtain a water phase, melting the lutein ester in the oil-soluble antioxidant to obtain an oil phase, adding the oil phase into the high-speed shearing water phase for emulsification, adding water solution of the inulin into the high-speed shearing water phase for uniform emulsification, carrying out high-pressure homogenization, and spraying and granulating the homogenized emulsification to obtain microcapsules with the particle size of 40-100 meshes. The invention also discloses the use of the lutein ester microcapsule preparation in the preparation of food, medicines and healthcare products with the functions of losing weight and / or protecting eyes. According to the lutein ester microcapsule preparation and as well as the preparation method and the use thereof disclosed by the invention, the obtained product has a high stability and has the functional effects of protecting eyes and losing weight.

Description

technical field [0001] The invention belongs to the technical field of new resource food, and in particular relates to a lutein ester microcapsule preparation and its preparation method and application. Background technique [0002] Lutein esters are carotenoid fatty acid esters in the form of lutein and fatty acids. It widely exists in plants such as marigold, cabbage and corn, especially the highest content in marigold. It can absorb blue light that is harmful to the retina, and has anti-oxidation effects, and plays an important role in the prevention and treatment of age-related macular degeneration and cataract diseases. [0003] Lutein crystals are difficult to emulsify due to their special property of being insoluble in oil and water. In order to improve stability and expand its application range, lutein ester microcapsules have been developed at home and abroad. Since lutein esters are wrapped in continuous capsules In the tiny capsule formed by the material, it avo...
