[0004] The existing microcapsules have poor water solubility, low stability, and are prone to qualitative changes. In the existing astaxanthin oil embedding technology, emulsification is used to process it, but the oil consumption is too large, the cost is high, and the current Some have a low embedding rate, resulting in high production costs

[0025] The invention provides a preparation method of astaxanthin microcapsules, comprising the following steps:
[0026] S1, using supercritical CO 2 The astaxanthin extract is obtained by extracting Yusheng red algae bulbs by fluid extraction method;
[0027] S2, mixing the astaxanthin extract, emulsifier and water and ultrasonically emulsifying to obtain astaxanthin oil;
[0028] S3, mixing the astaxanthin oil with a surfactant to obtain an oil phase core material;
[0029] S4. Mix the oil-phase core material and the water-phase wall material and embed them by spray drying, and then freeze-dry to obtain astaxanthin microcapsules;
[0030] The water phase wall material is a mixture of maltodextrin and hydroxypropyl-β-cyclodextrin.
[0031] see figure 1 , figure 1 It is a schematic flow diagram of the preparation process of astaxanthin microcapsules and the subsequent links provided by the present invention.

Embodiment 1
[0054] S1, using supercritical CO 2 The astaxanthin extract was obtained by extracting the red algae bulbs of Yusheng by fluid extraction method. The conditions of the supercritical extraction method are: temperature 31° C., pressure 7.3 MPa. Under the above supercritical conditions, the supercritical fluid is mixed with the red algae balls to extract the astaxanthin to obtain the astaxanthin extract.
[0055] S2. Take 0.05 g of astaxanthin extract, 0.1 g of sucrosefatty acid ester, 0.2 g of β-cyclodextrin, and 50 mL of water, and perform ultrasonic emulsification under the following conditions: the power is 100 W, and the time is 10 minutes, thereby obtaining astaxanthin oil.
[0056] S3. Mix astaxanthin oil and polysorbate-80 at a mass ratio of 4.76:0.87 to obtain an oil phase core material.
[0057] S4. Mix maltodextrin and hydroxypropyl-β-cyclodextrin in a mass ratio of 1:3 to obtain a water-phase wall material.
[0058] S5. Mixing the oil-phase core material and the w...

Abstract
The invention provides a preparation method of an astaxanthin microcapsule. The method comprises the following steps: s1, extracting haematococcus pluvialis pellets by using a supercritical CO2 fluid extraction method to obtain an astaxanthin extract; s2, mixing the astaxanthin extract, an emulsifier and water, and performing ultrasonic emulsification to obtain astaxanthin oil; s3, mixing the astaxanthin oil with a surfactant to obtain an oil phase core material; s4, mixing the oil phase core material and the water phase wall material for embedding through spray drying, then performing freeze drying to produce the astaxanthin microcapsules, wherein the water phase wall material is a mixture of maltodextrin and hydroxypropyl-beta-cyclodextrin. Through the preparation method, the stability of the astaxanthin microcapsule can be effectively improved. The preparation method is simple and easy to implement and low in cost.
Description
technical field [0001] The invention relates to the technical field of microcapsule preparation, in particular to a method for preparing astaxanthin microcapsules. Background technique [0002] Astaxanthin, also known as astaxanthin and lobster shell pigment, is a carotenoid and the highest grade product of carotenoid synthesis. It is dark pink in color and has a chemical structure similar to β-carotene. β-carotene, lutein, canthaxanthin, lycopene, etc. are all intermediate products of carotenoid synthesis, so in nature, astaxanthin has the strongest antioxidant activity. Widely present in the biological world, especially in the feathers of shrimp, crab, fish, algae, yeast and birds. It is one of the main carotenoids in marine organisms. The antioxidant capacity of astaxanthin is β- It is 10 times more carotene and 500 times more vitamin E. It is called "super vitamin E". Research by the University of Hawaii and a cooperative company have shown that astaxanthin can promote ...
