Embodiment 1

[0075] The present embodiment provides a kind of preparation method of grapefruit peel flavonoid gel ball, which is specifically as follows:

[0076] 1) Preparation of flavonoid core material emulsion: first, the peel of grapefruit is made into rough powder of peeled flavonoids, and then the crude extract of flavonoids from peel of grapefruit is added in a proportion of 2% of ethyl oleate and an emulsifier. In the mixed solution of polyoxyethylene hydrogenated castor oil and polyethylene glycol, fully mix until uniform to obtain flavonoid core material emulsion;

[0077] Among them, the volume ratio of ethyl oleate, polyoxyethylene hydrogenated castor oil and polyethylene glycol is 35:3:2; [oil phase (ethyl oleate) and emulsifier (polyoxyethylene hydrogenated castor oil and The volume ratio of ethylene glycol) is 7:1]

[0078] 2) Preparation of flavonoid sodium alginate core wall material mixture: under the condition of high-speed shearing at a rotational speed of 14,000 rpm,...

Embodiment 2～3

[0082] The present embodiment provides a preparation method of grapefruit peel flavonoid gel balls, the only difference from Example 1 is: in step 1), the co-emulsifier "polyethylene glycol" is replaced with "glycerol" or "1" , 2 Propylene Glycol".

[0083] During the experiment, Zetasiz laser particle sizer was used to measure particle size, polydispersity, and potential.

[0084] Taking ethyl oleate as oil phase and polyoxyethylene hydrogenated castor oil as emulsifier, the particle size of the emulsion after the treatment is smaller, and the polydispersed system numerical value is smaller (polyoxyethylene hydrogenated castor oil PdI 0.70, Tween 80 (polyethylene glycol) Diol) PdI 0.87, the smaller the PdI, the better the stability), the greater the absolute value of the potential (polyoxyethylene hydrogenated castor oil potential value -27.6, Tween 80 potential value -16.5, the greater the potential absolute value, the better the stability. it is good).

[0085]On the basi...

Embodiment 4～9

[0087] This embodiment provides a preparation method of grapefruit peel flavonoid gel ball, the difference from Example 1 is only in: "oil phase (ethyl oleate) and emulsifier (polyoxyethylene hydrogenated castor oil and polyethylene glycol) ) is 7:1" with "6:1", "5:1", "4:1", "2:1" or "8:1".

Abstract

The invention relates to a citrus peel flavonoid gel ball and its preparation method and application. The preparation method comprises: making citrus peel flavone coarse powder into a mixed solution of an oil phase and an emulsifier , fully mixed until uniform to obtain the flavonoid core material emulsion; then under the condition of high-speed shearing, the prepared flavonoid core material emulsion was slowly and uniformly added to the sodium alginate solution to obtain a micronized emulsion; then the obtained The micronized emulsion is subjected to high-pressure homogenization to obtain a flavonoid sodium alginate core wall material mixture; and then the flavonoid sodium alginate core wall material mixture is prepared by an orifice method to obtain citrus peel flavonoid gel balls. The preparation method provided by the present invention is simple and efficient, and the prepared citrus peel flavonoid gel balls are safe, non-toxic, and have a high embedding rate, and have certain slow-release and targeting effects. It is used in various health beverages and health ingredients.

Description

technical field [0001] The invention belongs to the field of food, and in particular relates to a grapefruit peel flavonoid gel ball and a preparation method and application thereof. Background technique [0002] Huyou is a Rutaceae plant, a hybrid of pomelo and sweet orange. The single fruit weighs about 300 grams, the skin thickness is about 0.6 cm, the edible rate is 70%, and the soluble solids are 11-13.2%. As of 2017, the planting area of ​​Huyou has grown to 7,000 hectares, with an annual output of 128,000 tons and an output value of nearly 450 million yuan. Huyou peel is a waste product from Huyou processing, but it contains many beneficial components, especially flavonoids. Flavonoids have antioxidant, anti-tumor, anti-diabetic, anti-cardiovascular, anti-inflammatory, anti-depressant, and anti-allergic effects, and are widely used both in medicine and in the food industry. The acute toxicity of flavonoids is extremely small after querying the chemical database of t...
