Embodiment 1

[0037] Take 5 g of high-purity lutein crystals, 5 g of povidone K90, 2.5 g of Tween 70, and 50 ml of acetone, stir for 5 minutes, fully dissolve, and evaporate to dryness in a normal-pressure water bath at 60°C. After being embrittled, take it out and crush it through an 80-mesh sieve.

Embodiment 2

[0039] Take 10g of 80% lutein, 20g of polyethylene glycol 2000, 10g of Tween 65, and 60ml of ethyl acetate, stir for 10 minutes and fully dissolve, and evaporate to dryness in a water bath with a vacuum of 0.7 MPa at 30°C. After being embrittled, take it out and crush it through an 80-mesh sieve.

Embodiment 3

[0041]Take 15g of 70% lutein, 45g of povidone K29, 10g of fatty acid sucrose ester SE15, and 100ml of absolute ethanol, stir for 20 minutes and fully dissolve, and evaporate to dryness in a water bath with a vacuum of 0.9 MPa at 35°C. After being embrittled, take it out and crush it through an 80-mesh sieve.

Abstract

The invention relates to a preparation process of a lutein water-solubility powder with good water-solubility, stable properties and good liquidity, which belongs to the technical field of medicines. The lutein water-soluble powder disclosed in the invention comprises the following prescription components in proportion by weight: lutein powder to a carrier to an additive of 1: (1-10):(0-3). The lutein water-solubility powder prepared by adopting a dissolvent way can be prepared into various dissolvent forms or added to various functional foods. In the lutein water-soluble powder prepared by the process, the dissolution rate of lutein can reach 96%. The lutein water-soluble powder has the advantages of good water-solubility, high stability, good liquidity, 34 DEG of angle of repose and good dispersity, and can be applied to various fields such as foods, medicines, cosmetics and the like.

Description

technical field [0001] The invention belongs to the technical field of medicine and relates to a water-soluble lutein powder and a preparation process thereof, in particular to a water-soluble lutein powder which is instant in water and has good stability and a preparation process thereof. Background technique [0002] Lutein, also known as "plant lutein", exists together with zeaxanthin in nature. It is the main component of plant pigments such as corn, vegetables, fruits, flowers, etc. It is contained in the chloroplast of leaves, and can transmit the absorbed light energy to chlorophyll a. It is speculated that it has a protective effect on photooxidation and photodestruction. It is also the main pigment that constitutes the macular area of ​​the human eye. Medical experiments have proved that the natural lutein contained in plants is an antioxidant with excellent performance. Adding a certain amount of lutein to food can prevent cell aging and organ aging, and can als...
