[0030] combine figure 1 Shown, the present invention provides a kind of preparation method of Aronia nigra extract, comprises the steps:
[0031] Wet crushing Aronia adenocarpus to prepare Aronia adenocarpa slurry;
[0032] Mix the Aronia sarcophagus slurry with water and carry out high-pressure differential and low-temperature extraction to prepare the extract of Aronia sativa; wherein, the conditions for the high-pressure differential and low-temperature extraction are: the pressure is 20MPa-40MPa, and the temperature is 5°C- 25°C;
[0033] centrifuging and filtering the extract of Aronia nigricarpa, and concentrating the obtained filtrate to prepare a concentrated solution of Aronia nigricarpa;
[0034] The concentrated solution of Aronia nigricarpa is subjected to column chromatography, and then freeze-dried or dried under reduced pressure.
[0035] In the present invention, the equipment used for high-pressure differential low-temperature extraction includes, but is no...
Embodiment 1
[0070] The present embodiment provides a kind of preparation method of Aronia nigra extract, specifically as follows:
[0071] Pick and remove the moldy and rotten parts of 80kg Aronia adenocarpus fruit, remove the fruit stalk, and then put it in a high-efficiency turbine pulverizer equipped with a 1.2mm sieve, and use 1 times purified water to pass through the 1.2mm sieve Carry out wet crushing to obtain finely crushed pulp, and add 18 times of purified water to the finely crushed pulp of Sorbus nigra, and then use high-efficiency high-pressure differential low-temperature continuous extraction equipment for low-temperature instant extraction. The extraction pressure is 30MPa at low pressure and 35MPa at high pressure. The extraction temperature is 23°C, and the number of extractions is 1 time; the extract is collected and centrifuged at a speed of 10,000r / min, and the centrifuged liquid is subjected to 500nm ceramic membrane microfiltration to obtain a clear filtrate. The pr...
