Embodiment 1

[0030] Embodiment 1: Preparation of aronia anthocyanin microcapsules

[0031] The preparation process of Aronia anthocyanin-rich microcapsules involved in this example mainly includes five steps: preparation of wall material solution, preparation of wall material emulsifier solution, preparation of anthocyanin core material oil solution, microcapsule preparation and spray drying :

[0032] (1) Preparation of wall material: mix maltodextrin and gelatin at a weight ratio of 1:1, add a certain amount of distilled water and stir at 65°C for 10 minutes, and stir evenly to make a mixed wall material solution with a concentration of 8% by weight;

[0033] (2) Preparation of wall material emulsifier solution: mix and stir the wall material solution prepared in step (1) with the emulsifier at a weight ratio of 1:1 until the mixed solution reaches complete emulsification, and then the wall material emulsifier solution is obtained. The emulsifier is Prepared by mixing Tween 80 and Span ...

Embodiment 2

[0039] Embodiment 2: Aronia anthocyanin microcapsules

[0040] The preparation process of microcapsules rich in Aronia anthocyanins involved in this example is similar to the steps in Example 1, but the ratio parameters are slightly different, as follows:

[0041] (1) Preparation of wall material: mix soybean lecithin, maltodextrin, and carboxymethyl cellulose in a weight ratio of 1:1:1, add a certain amount of distilled water and stir at 70°C for 10 minutes, and stir evenly to make a concentration of 10 The mixed wall material solution of % weight ratio;

[0042] (2) Preparation of wall material emulsifier solution: mix and stir the wall material solution prepared in step (1) with emulsifier Tween-80 at a weight ratio of 1:1.5 until the mixed solution reaches complete emulsification, and then obtain the wall material emulsifier solution ;

[0043] (3) Preparation of core material: prepare 30% aronia anthocyanin solution, add vitamin C according to 0.5% of aronia anthocyanin...

Embodiment 3

[0048] Embodiment 3: the influence of the content of wall material on the preparation of anthocyanin microcapsules

[0049] (1) Preparation of the wall material: select the wall material to be one or more of soybean lecithin, maltodextrin, carboxymethyl cellulose, gelatin and mix in proportion, add a certain amount of distilled water and stir for a period of time at a certain temperature, Stir evenly to make a mixed wall material solution with a certain concentration, and the specific parameters are shown in Table 1;

[0050] (2) Preparation of wall material emulsifier solution: mix and stir the wall material solution prepared in step (1) with the emulsifier at a weight ratio of 1:1 until the mixed solution reaches complete emulsification, and then the wall material emulsifier solution is obtained. The emulsifier is Prepared by mixing Tween 80 and Span at a weight ratio of 2:1;

[0051] (3) Preparation of core material: prepare 30% aronia anthocyanin solution, add vitamin C a...

Abstract

The present invention discloses an aronia anthocyanin-enriched micro-capsule and a preparation method thereof, and belongs to the technical field of biopharmaceuticals. The preparation technology of the aronia anthocyanin-enriched micro-capsule mainly comprises five steps of wall material solution preparing, wall material emulsifier solution preparing, anthocyanin core material oil solution preparing, microcapsule preparing and spray-drying. Appropriate packaging materials are selected to prepare the wall material solution at a concentration of 6%-10%; the emulsifier is added to the wall material solution to realize the microencapsulation of the aronia anthocyanins; and at the same time, a certain amount of vitamin C and vitamin E are added into the wall core material to improve the stability of the aronia anthocyanins. The anthocyanin microencapsulation improves the dispersibility and stability of the aronia anthocyanins, solves problems that the aronia anthocyanins are unstable in nature, easy to degrade and difficult to store. The aronia anthocyanin-enriched micro-capsule has wide practicality, further expands the application scope of the anthocyanins in the field of food technology and realizes wider application value.

Description

technical field [0001] The invention relates to a microcapsule rich in aronia anthocyanins and a preparation method thereof, belonging to the technical field of biopharmaceuticals. Background technique [0002] Aronia fruit is rich in anthocyanins and polyphenols, which have extraordinary health effects. The anthocyanins and polyphenols in the fruit are the highest in known fruits and berries. Studies have shown that wild aronia produced in Poland contains 80 times more anthocyanins and polyphenols than grapes, 20 times wolfberry, 15 times cranberry, and more than 5 times blueberry. [0003] Anthocyanins are polyphenolic compounds of a class of flavanol monomers and their polymers, and are currently internationally recognized as the most effective natural antioxidants for removing free radicals in the human body. Experiments have shown that its anti-free radical oxidation ability is 50 times that of vitamin E and 20 times that of vitamin C, and it is absorbed quickly and co...
