Embodiment Construction

[0025] A production process of blueberry extract with anthocyanins ≥ 25%, the process includes: soaking blueberry raw materials in acid water, high-voltage electric field extraction, rough filtration, fine filtration, reverse osmosis, AB-8 resin refining, reverse osmosis, spray drying, Finished product; the specific steps are:

[0026] (1) High-voltage electric field extraction: take 100 parts by mass of blueberry raw materials, crush them through a 40-mesh sieve, add 10 times the mass parts of blueberry raw materials, and soak in acidic water with pH 2 at room temperature for 1 hour, and then use a high-voltage electric field extraction device to extract 12 pulses in the electric field. Extract under the condition of intensity of 45kV / cm, extraction time is 2 hours;

[0027] Above-mentioned acid water used is oxalic acid aqueous solution or acetic acid aqueous solution etc.

[0028] (2) Filtration: After the above-mentioned extracted liquid is roughly filtered with a 200-mes...

Abstract

The invention discloses a production process of a blueberry extract with more than or equal to 25% of anthocyanin and relates to the technical fields of bioengineering and new medicines. The technological process comprises the following steps: (1) performing high-voltage electric field extraction, namely crushing a blueberry material, adding acid water to dip the crushed blueberry material, and extracting by using a high-voltage electric field extraction device; (2) filtering; (3) allowing an extracting liquid to pass through a reverse osmosis membrane device; (4) absorbing the concentrated extracting solution by using AB-8 resin, performing gradient elution, and at last, collecting an eluant; (5) allowing the collected eluant to pass through the reverse osmosis membrane device again so as to achieve a concentration effect; (6) spraying and drying the concentrated eluant without any auxiliary material to prepare a finished product. The production process has the following advantages: (1) saving energy and reducing emission; (2) improving the extraction efficiency due to the use of an advanced technology, simplification of process and continuity of the production process; (3) effectively improving the product yield.

Description

Technical field [0001] The present invention involves the field of biological engineering and new pharmaceutical technology, and specificly involves the separation and extraction method of effective ingredients of natural products. Background technique [0002] ⑴ General process steps of blueberry anthocyanins: extraction (with 50%ethanol of PH2 as a solvent, heating and soaking three times, 70 ° C, three solvents for three times are 8BV, 6BV, and 4BV, respectively, 60min, respectively, respectively, respectively, respectively, respectively 60min, respectively.30min, 30min.) → Filter the centrifugal miscellaneous miscellaneous (after the extraction solution is filtered with a 200 mesh filter, the bottom residue is removed after the centrifuge of the centrifuge.) → concentration (60 ° C vacuum concentration, recycling ethanol, anthocyanins extraction solution) →Resin adsorption and eluation (above AB-8 resin adsorption, collecting 60%ethanol to elux) → concentration (60 ° C vacuum...
