Embodiment 1

[0025] Lutein oleoresin microcapsules were prepared from lutein oleoresin (the content of lutein was 206g / kg lutein oleoresin). The lutein content is determined according to the American AOAC standard.

[0026] Heat 60g of the core material lutein oleoresin to 30°C under stirring, add 5g of sucrose ester, stir until dissolved, and obtain the core material phase. Add 24g of gelatin to 72mL of water, heat to 90°C, and stir to dissolve the gelatin. Add 8g of sodium caseinate and 3g of citric acid, stir until dissolved, and obtain the capsule material phase. The core material phase and the capsule material phase are mixed, emulsified and homogenized by a high-pressure homogenizer at 80 MPa to form an emulsion, and the particle size of the emulsion reaches 200 nm. Under the conditions of an inlet air temperature of 210° C. and an outlet air temperature of 110° C., the emulsion is dried in a spray drying tower to obtain lutein oleoresin microcapsule powder.

Embodiment 2

[0031] Lutein oleoresin microcapsules were prepared from lutein oleoresin (the content of lutein was 206g / kg lutein oleoresin).

[0032] Heat 10 kg of core material lutein oleoresin to 70° C. under stirring, add 0.5 kg of phospholipid, stir until dissolved, and obtain the core material phase. Add 88L of water to 88kg gum arabic, heat to 50°C, stir to dissolve the gum arabic. Add 1 kg of casein acid and 0.5 kg of sodium dihydrogen phosphate, stir until dissolved, and obtain the capsule material phase. The core material phase and the capsule material phase are mixed, emulsified and homogenized by a high-pressure homogenizer at 20MPa to form an emulsion, and the particle size of the emulsion reaches 350nm. Under the conditions of an inlet air temperature of 160°C and an outlet air temperature of 70°C, the emulsion is dried in a spray drying tower to obtain lutein oleoresin microcapsule powder.

[0033] Obtain 96.7kg orange red lutein oleoresin powder by this method, wherein the...

Embodiment 3

[0037] Lutein oleoresin microcapsules were prepared from lutein oleoresin (the content of lutein was 206g / kg lutein oleoresin).

[0038] Heat 30 kg of core material lutein oleoresin to 50° C. under stirring, add 1 kg of monoglycerides of fatty acids, stir until dissolved, and obtain the core material phase. Add 88L of water to 45kg of modified starch and 20kg of dextrin, heat to 50°C, and stir to dissolve the modified starch and dextrin. Add 2.5 kg of potassium caseinate and 1.5 kg of potassium dihydrogen phosphate, stir until dissolved, and obtain a capsule material phase. The core material phase and the capsule material phase are mixed, emulsified and homogenized by a high-pressure homogenizer at 40 MPa to form an emulsion, and the particle size of the emulsion reaches 230 nm. Under the conditions of 200°C inlet air temperature and 100°C outlet air temperature, the emulsion is dried in a spray drying tower to obtain lutein oleoresin microcapsule powder.

Abstract

The invention discloses a method for preparing a lutein oleoresin microcapsule, which comprises the steps of: 1) preparing a lutein oleoresin core material, 2) preparing a capsule material, 3) mixing the lutein oleoresin core material with the capsule material and uniformly emulsifying the mixture into emulsified liquid at nanometer level, and 4) drying the emulsified liquid. The method of the invention uses the microcapsule technique to treat the lutein oleoresin and uses natural or synthesized high polymer material to pack the lutein oleoresin drops into a microcapsule, so the obtained product has better water-solubility and stability, the industrial production can be realized, and the problems of the prior art that the application scope is narrow and the stability is inferior are solved.

Description

technical field [0001] The invention relates to the field of bioengineering, in particular to a method for preparing lutein oleoresin microcapsules. Background technique [0002] Carotenoids are fat-soluble plant pigments widely found in nature. Carotenoids are mainly divided into two categories: carotene and lutein. Natural lutein, also known as plant "lutein", exists in the form of combining with higher fatty acids such as palmitic acid, stearic acid, lauric acid or myristic acid to form fat (ie lutein oleoresin). Medical experiments have proved that lutein contained in plants is an antioxidant with excellent performance. Adding a certain amount of lutein to food can prevent a series of diseases caused by cell aging and aging of body organs, such as retinal macular degeneration , cataract, colon cancer, cardiovascular sclerosis, coronary heart disease, etc. At the same time, lutein can also be used as a feed additive for the coloring of poultry meat and eggs, and it has...
