[0026] The preparation method of bee pollen total flavonoids extract is as follows: take buckwheat bee pollen as raw material, take the ethanol of concentration 75% as extraction solvent, according to the solid-liquid ratio is 1: 10, heat and reflux for 2 hours, centrifuge, take supernatant, filter residue Repeat the above operations, combine the supernatants twice, concentrate, and then freeze-dry to obtain a powder extract, that is, the bee pollen total flavonoids extract.
[0027] The total flavonoid content in bee pollen flavonoid-β-CD inclusion complex was 3.85mg / g.
[0028] Emulsion stabilizer is sodium carboxymethyl cellulose.
[0029] The preparation method of the above-mentioned bee pollen antioxidant milk provided by the embodiment of the present invention comprises the following steps:
[0030] Step 1, preparing bee pollen flavone-β-CD inclusion compound;
[0031] The preparation of bee pollen flavone-β-CD clathrate is carried out according to the following method...
Embodiment 1
[0041] The preparation method of bee pollen total flavonoids extract in the present embodiment is: take buckwheat bee pollen as raw material, take the ethanol of concentration 75% as extraction solvent, be 1: 10g / L according to solid-liquid ratio, heat and reflux for 2 hours, centrifuge, Take the supernatant, then add the obtained filter residue to the extraction solvent again according to the above-mentioned operation method, and perform the steps of heating to reflux, centrifuging, and taking the supernatant; combine the supernatant twice, concentrate, and then freeze-dry to obtain a powder extract, namely The bee pollen total flavonoid extract. The freeze-drying was carried out in a freeze-drying machine, and the freeze-drying machine used was the LGJ-FD-1 freeze-drying machine of Xi'an Yuhui Instrument Co., Ltd.
[0042] Preparation of Bee Pollen Flavone-β-CD Inclusion Complex
Embodiment 2
[0044] Prepare bee pollen total flavonoids extract according to Example 1, use the prepared bee pollen total flavonoids extract as the core material, use β-cyclodextrin as the wall material, and use the ratio of 1:4 according to the mass ratio of the core and wall materials Weigh the bee pollen total flavonoids extract and β-cyclodextrin, then add distilled water to the β-cyclodextrin to prepare a saturated solution at 40°C. When preparing a 40°C saturated solution of β-cyclodextrin, the - Cyclodextrin is added in a ratio of 25ml of distilled water, and the total flavonoids extract of bee pollen is dissolved in an ethanol solution with a concentration of 75%, and slowly added dropwise to the β-CD saturated solution at 40°C, stirred at constant temperature for 2 hours, and cooled to room temperature , let stand at 4°C for 24 hours, then vacuum filter, rinse the filter residue with a small amount of absolute ethanol quickly, after the ethanol is evaporated, put the filter residue...
