Embodiment 1
[0019] Use 20 grams of blueberry fruit pomace as raw material, dry in a ventilated drying oven to remove moisture, put it into a flat-bottomed flask, add 2 times the volume, pH of 2, and a concentration of 30% ethanol solution, place it on a water bath, and place it in a water bath. Reflux extraction at 30°C for 0.5 hours, filter with a Buchner funnel and collect the filtrate and residue respectively. Put the residue into a flat-bottomed flask, add 2 times the volume of ethanol solution with a pH of 2 and a concentration of 30%, reflux extraction under the same conditions for 0.5 hours and then filter, combine the two filtrates and put them into a flat-bottomed flask, and then put Put it into a refrigerator at a temperature of 0°C and let it stand for 10 hours. Then, the refrigerator was taken out, filtered with a Buchner funnel, the filtrate was placed on a rotary evaporator, and concentrated at 50° C. for 10 hours to obtain 50 ml of a concentrated solution. After passing th...
Embodiment 2
[0021] Take 20 grams of blueberry fruit pomace as raw material, dry it in a ventilated drying oven to remove moisture, put it into a flat-bottomed flask, add 5 times the volume, PH is 3, and a concentration of 80% ethanol solution, put it on a water bath, and put it in a water bath. Reflux extraction at 50°C for 1 hour, filter with a Buchner funnel and collect the filtrate and residue respectively. Put the residue into a flat-bottomed flask, add 5 times the volume of ethanol solution with a pH of 3 and a concentration of 80%, reflux extraction under the same conditions for 1 hour and then filter, and combine the two filtrates. The filtrate was placed on a rotary evaporator and concentrated at 50° C. for 12 hours to obtain 150 ml of a concentrated solution. Put the concentrated solution into a flat-bottomed flask, put it into a refrigerator with a temperature of 4° C., and let it stand for 12 hours. Then, take out the refrigerator, filter with a Buchner funnel, pass the filtra...
Embodiment 3
[0023] Take 20 grams of blueberry pomace as raw material, dry it in a ventilated drying oven to remove moisture, put it into a flat-bottomed flask, add 10 times the volume, PH is 6, and the concentration is 60% ethanol solution, put it on a water bath, and put it in a water bath. Reflux extraction at 90°C for 2 hours, filter with a Buchner funnel and collect the filtrate and residue respectively. Put the residue into a flat-bottomed flask, add 10 times the volume of ethanol solution with a pH of 6 and a concentration of 60%, reflux extraction under the same conditions for 2 hours and then filter, and combine the two filtrates. Put the combined filtrate into a flat-bottomed flask, put it into a refrigerator with a temperature of 2° C., and let it stand for 11 hours. Then, the refrigerator was taken out, filtered with a Buchner funnel, the filtrate was placed on a rotary evaporator, and concentrated at 50° C. for 10-12 hours to obtain 200 ml of a concentrated solution. After pa...
