Problems solved by technology

[0004] At present, the existing pollen food on the market is mainly based on the primary processing of pollen, such as pollen honey, pollen granules, etc., which retain more nutrients in pollen, but also have a relatively strong taste and smell of pollen, which is not easy for most people. accepted
In order to develop pollen products that are more acceptable to most people and rich in nutrition, the author found through investigation and comparison that there are no reports in the literature at home and abroad on the production of functional dairy products using buckwheat bee pollen as raw materials

preparation example Construction

[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 compound 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 metho...

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...

Abstract

The invention discloses bee pollen antioxidant milk. The bee pollen antioxidant milk is prepared from, by mass percentage, 80-90% of raw cow milk, 3-6% of bee pollen flavone-beta-CD clathrate compound, 3-6% of saccharose, 0.05-0.20% of vitamin C, 0.03-0.10% of stabilizer and the balance water. The method for preparing the bee pollen antioxidant milk comprises a step 1 of preparing the bee pollen flavone-beta-CD clathrate compound; a step 2 of dissolving obtained bee pollen flavone-beta-CD clathrate compound and the stabilizer respectively to prepare solution, mixing the solution with the vitamin C and the saccharose, adding the water simultaneously, stirring the mixture uniformly and mixing the mixture with the raw cow milk; and a step 3 of homogenizing and sterilizing to obtain the bee pollen antioxidant milk. The prepared bee pollen antioxidant milk has unique flavor and both taste and odor of the milk and fragrance of pollen, particularly has an antioxidant health care function and is a good novel health care dairy product.

Description

technical field [0001] The invention belongs to the technical field of food and beverage processing, and in particular relates to a bee pollen antioxidant milk and a preparation method thereof. Background technique [0002] Bee pollen refers to the pollen collected by bees from the anthers of flowering plants-nectar plants, after the bees add nectar and saliva to the inside, and mix them into irregular oblate balls. Modern scientific research has found that in addition to protein, fat, sugar, vitamins and minerals, bee pollen also contains rich nutrients, such as essential amino acids, unsaturated fatty acids, vitamins, polyphenols and flavonoids , polysaccharides and other active substances, known as "miniature nutrition library". Pharmacological experiments have shown that bee pollen has the effects of lowering blood fat, anti-radiation, enhancing immune function, protecting the liver, treating benign prostatic hyperplasia, and anti-aging. Therefore, it has caused an upsu...
