Problems solved by technology

[0004] However, a large amount of organic solvent ethanol or isopropanol is used in the preparation process of the compound lutein microcapsules, and the oil phase solvent mixture needs to be heated to 170-230° C. and then put into the water phase solvent mixture, which may cause oxidation of unsaturated fatty acids
That is to say, although the solution improves the solubility and bioavailability of lutein, there are still problems such as complex preparation process and safety risks.

Abstract

The invention provides lutein compound micro-capsule powder and a preparation method and application thereof. The lutein compound micro-capsule powder comprises the following raw materials: lutein, oil-phase components, water-phase components and emulsifiers, the mass ratio of the lutein to the oil-phase components is 1: (1-10), and the oil-phase components are composed of hippophae rhamnoides seed oil and walnut oil according to the mass ratio of (2-7): 1. According to the invention, the lutein is dissolved in the specific oil phase components composed of the hippophae rhamnoides seed oil and the walnut oil, the lutein is wrapped firstly, so that the stability of the lutein is improved, zeaxanthin and lycopene rich in the hippophae rhamnoides seed oil are compounded with the lutein, so that the bioavailability of the lutein is improved, there is no need to use a large amount of organic solvents such as ethanol or to utilize an ester form of the lutein, and the obtained microcapsule powder has an excellent eye protection effect, with wide application prospects in the fields of foods, medicines, health-care products, etc.

Description

technical field [0001] The invention relates to the field of lutein-related functional foods, in particular to a compound microcapsule powder of lutein and its preparation method and application. Background technique [0002] Lutein is a carotenoid. Lutein can be deposited in the macula of the human eye. It acts as an antioxidant or photoprotectant to filter blue light entering the eye. It is important for the prevention of cataracts and age-related macular degeneration. However, the molecular structure of lutein contains multiple conjugated double bonds, which are susceptible to degradation or isomerization under the influence of light, heat, oxygen, metal ions, acidic conditions and other pro-oxidants, resulting in the loss of biological activity, and the crystalline form The existing lutein is difficult to be completely released and absorbed in the digestive tract. Therefore, unstable chemical properties, poor water solubility, and low oral bioavailability severely limit...
