Abstract

The invention discloses a preparation method of chlorophyll-sodium alginate microspheres. The method comprises the steps as follows: (1) preparing a sodium alginate solution; (2) adding lutein, magnesium stearate and liquid paraffin to the sodium alginate solution, performing stirring and ultrasonic treatment, passing a high-pressure homogenizer 3 times under the pressure of 30 MPa, and leaving the obtained solution to stand for 2-3 h to obtain a mixed emulsion; (3) dropwise adding the obtained mixed emulsion to a calcium chloride solution in a stirring state, after addition, performing stiring and suction filtration, washing the obtained material by distilled water 3 times, leaving the obtained material to stand for 24 h at room temperature, and performing vacuum drying. The prepared chlorophyll-sodium alginate microspheres have round appearance forms, porous performance and good dispersity and stability and can swell in a colon pH environment to release easily.

Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to a preparation method of chlorophyll-sodium alginate microspheres. Background technique [0002] Lutein is a natural carotenoid with bright color, strong tinting power, good anti-oxidation, safe and non-toxic. Lutein widely exists in vegetables, flowers, fruits and some algal plants, and is used in food, health products, medicine and other fields. The U.S. Food and Drug Administration has approved lutein as a food supplement as early as 1995. The latest research results show that lutein can protect vision, prevent cataracts, prevent arteriosclerosis, and enhance immunity. In addition, preventing cancer and delaying cancer are also the research focus of current scientists. [0003] Lutein is a fat-soluble pigment, soluble in organic solvents, and has multiple conjugated double bonds in its chemical structure, which is highly unsaturated. Lutein is very sensitive to ligh...
