Embodiment 1

[0044] (1) Preparation of lutein core-wall material mixture: 4 g of natural lutein (core material) and 32 g of sodium caseinate (wall material) were weighed and dissolved in 200 mL and 600 mL of 40% edible alcohol respectively. Heat the completely dissolved sodium caseinate alcohol solution at 60°C for 5 minutes, then add the lutein alcohol solution dropwise to the sodium caseinate alcohol solution on a magnetic stirrer, and keep stirring for 10 minutes to obtain the lutein core-wall material mixture. Filter the obtained lutein core-wall material mixture with a 100-mesh sieve to remove large insoluble particles.

[0045] (2) High-speed dispersion: the filtered mixed solution was dispersed at a high speed of 10,000 rpm for 4 minutes, rested for 15 seconds every 30 seconds, and dispersed 8 times to obtain a lutein-sodium caseinate microemulsion with uniform texture;

[0046] (3) Spray drying: The obtained lutein-sodium caseinate microemulsion was spray-dried at an inlet tempera...

Embodiment 2

[0048] (1) Preparation of lutein core-wall material mixture: 4g of natural lutein and 48g of sodium caseinate were weighed and dissolved in 200mL and 600mL of 40% edible alcohol respectively. Heat the completely dissolved sodium caseinate alcohol solution at 60°C for 5 minutes, then add the lutein alcohol solution dropwise to the sodium caseinate alcohol solution on a magnetic stirrer, and keep stirring for 140 minutes to obtain the lutein core-wall material mixture. Filter the obtained lutein core-wall material mixture with a 100-mesh sieve to remove large insoluble particles.

[0049] Step (2) is the same as in Example 1.

[0050] (3) Spray drying: The obtained lutein-sodium caseinate microemulsion is spray-dried at an inlet temperature of 200° C. and an outlet temperature of 90° C. to obtain dry lutein microcapsules.

Embodiment 3

[0052] (1) Preparation of lutein core-wall material mixture: 4 g of natural lutein and 4 g of sodium caseinate were weighed and dissolved in 200 mL and 600 mL of 40% edible alcohol respectively. Heat the completely dissolved sodium caseinate alcohol solution at 60°C for 5 minutes, then add the lutein alcohol solution dropwise to the sodium caseinate alcohol solution on a magnetic stirrer, and keep stirring for 125 minutes to obtain the lutein core-wall material mixture. Filter the obtained lutein core-wall material mixture with a 100-mesh sieve to remove large insoluble particles.

[0053] Step (2) is the same as in Example 1.

[0054] (3) Spray drying: The obtained lutein-sodium caseinate microemulsion was spray-dried at an inlet temperature of 185° C. and an outlet temperature of 90° C. to obtain dry lutein microcapsules.

Abstract

The invention relates to a preparation method of lutein microcapsules and a lutein microcapsule instant beverage, and belongs to the field of foods. According to the lutein microcapsules, lutein is used as a core material, sodium caseinate is used as a wall material, the embedding rate of lutein in the microcapsules is as high as 97%, the dissolving speed of the microcapsules in water is 44 s, the quality of the microcapsules is good, raw materials are food-grade foods or are from foods, and are non-toxic and high in safety, the microcapsules can be eaten, and the digestibility and the absorptivity of the lutein microcapsules are better than those of natural lutein. According to the lutein microcapsule instant beverage disclosed by the invention, the lutein microcapsules, yellow corn grits and apricot kernels are used as main raw materials, and steviol glycoside is used as sweetening agent. The beverage is good in mouth feel, the content of main nutrient substances including zeaxanthin and lutein is also very high, only a small quantity of the beverage needs to be brewed every day, and the intake 10mg / day of the lutein by a healthy adult, suggested by WHO / FAO, can be met; and the beverage contains coarse food grains namely corn and a non-cane sugar sweetening agent, so that the beverage is the unique choice of health-care foods for middle-aged people, old people and patients suffering from diabetes.

Description

technical field [0001] The invention relates to a preparation method of lutein microcapsules and an instant drink of lutein microcapsules, belonging to the field of food. Background technique [0002] Lutein (LUT for short), that is, 3,3'-dihydroxy-β,α-carotene, molecular formula C 40 h 56 o 2 , with a molecular weight of 568.88, is a fat-soluble substance, not easily soluble in water, but easily soluble in fatty solvents and some organic solvents. It has many beneficial health effects on the human body. Studies have proved that taking a certain amount of lutein in the diet can prevent the aging of the body's organs and cells, and it can also prevent the eyesight of the middle-aged and elderly people caused by retinal macular disease. Falling and blindness can also reduce the damage caused by light to the light-sensitive cells in the macula of the retina. The photoprotection and anti-oxidation effects of lutein can inhibit the generation of harmful free radicals in the ey...
