Problems solved by technology

At present, two methods are mainly used for the preparation of carotenoid preparations: one is to dissolve in a solvent, and the solvent is removed in the subsequent process. Due to the use of organic solvents in this method, there is a risk of solvent residue in the product; the other is to dissolve at high temperature. Under high pressure conditions, it is processed by melting, and the production conditions are harsh, and under high temperature conditions, carotenoids will be oxidized to varying degrees, resulting in a decrease in the yield of the product

Embodiment 1

[0019] The preparation method of a kind of carotenoid preparation in the present embodiment, the method step is as follows:

[0020] 1) Add 1 part of lycopene crystal (content 98%), 3 parts of gum arabic, and 0.1 part of ascorbic acid into 3 parts of purified water, stir to dissolve and emulsify evenly;

[0021] 2) Transfer the material prepared in step 1) to a grinding equipment for grinding, from coarse to fine, grind in 2 stages, grind for 15 minutes in each stage, and grind for 30 minutes in total, and take a sample from Malvern 3000 to measure the particle size to 2.02 μm;

[0022] 3) Spray-dry the material obtained in step 2) with a particle size of 2.02 μm at an air inlet temperature of 110° C. and a feed rate of 120 ml / min, and perform secondary granulation by starch embedding to obtain lycopene microcapsules.

Embodiment 2

[0024] The preparation method of a kind of carotenoid preparation in the present embodiment, the method step is as follows:

[0025] 1) Add 1 part of β-carotene crystal (content 98%), 5 parts of modified starch, and 0.2 part of sodium ascorbate into 12.5 parts of purified water, stir to dissolve and emulsify evenly;

[0026] 2) Transfer the material prepared in step 1) to a grinding equipment for grinding, from coarse to fine, grind in 5 stages, grind for 30 minutes in each stage, and grind for 150 minutes in total, and take a sample of Malvern 3000 to measure the particle size to be 0.185 μm;

[0027] 3) The material obtained in step 2) with a particle size of 0.185 μm was spray-dried under the conditions of an inlet air temperature of 110° C. and a feed rate of 120 ml / min, and secondary granulation by starch embedding to obtain β-carotene microcapsules.

Embodiment 3

[0029] The preparation method of a kind of carotenoid preparation in the present embodiment, the method step is as follows:

[0030] 1) Add 1 part of 8'-apo-β-carotaldehyde crystal, 10 parts of sodium lignosulfonate, and 0.3 part of vitamin E into 15 parts of purified water, stir to dissolve and emulsify evenly;

[0031] 2) The material prepared in step 1) was transferred to a grinding equipment for grinding, from coarse to fine, divided into 8 stages of grinding, each stage was ground for 20 minutes, and a total of 160 minutes of grinding was taken. The particle size was determined to be 0.172 μm by sampling Malvern 3000;

[0032] 3) Spray-dry the material obtained in step 2) with a particle size of 0.172 μm at an air inlet temperature of 110°C and a feed rate of 120ml / min, and perform secondary granulation by starch embedding to obtain 8'-Apo-β -Carotaldehyde microcapsules.

Abstract

The invention relates to a preparing method of a carotenoid preparation. The method comprises the following steps: 1) adding carotenoid and other raw materials into purified water, stirring, dissolving and emulsifying evenly; 2) transferring the materials prepared in the step 1) into a grinding device, grinding, sampling and measuring the particle size of 0.01-2 [mu]m; and 3) carrying out spray drying on the obtained material with the particle size of 0.01-2 [mu]m in the step 2), embedding with starch, and carrying out secondary granulation, to obtain carotenoid microcapsules. In the method, residues of an organic solvent on the microcapsules are effectively avoided, and no residual risk of the solvent exists; and preparation does not need to be carried out under conditions of high temperature and high pressure, the yield is improved, the process is simple, the preparation conditions are improved, the production process is optimized, and the industrialized production of the product isfacilitated.

Description

technical field [0001] The invention relates to the technical field of medical food processing, in particular to a preparation method of a carotenoid preparation. Background technique [0002] Carotenoids are a class of polyene compounds with multiple unsaturated bonds, which can be used as functional health ingredients or colorants in food, such as α-carotene or β-carotene, 8'-Apo- β-carotaldehyde, 8'-apo-β-ethyl carotate, canthaxanthin, astaxanthin, lycopene, lutein, zeaxanthin or crocin, etc. At present, two methods are mainly used for the preparation of carotenoid preparations: one is to dissolve in a solvent, and the solvent is removed in the subsequent process. Due to the use of organic solvents in this method, there is a risk of solvent residue in the product; the other is to dissolve at high temperature. Under the condition of high pressure, the method of melting is used, the production conditions are harsh, and under the condition of high temperature, carotenoids w...
