Embodiment 1
[0021] Wash and crush the red dates with pitting, the particle size is 5 mesh, take 1000g red dates, add 5000ml of 15% ethanol, the temperature of the water bath is 25°C, the ultrasonic extraction time is 30 minutes, the ultrasonic frequency is 50kHz, and the ultrasonic intensity is 0.4W / cm 2 , coarsely filter the extract obtained by ultrasound, add the same weight of extraction solvent to the filter residue and repeat the ultrasonic extraction for 2 times, filter and combine all the extracted jujube juices, a total of 1350ml.
[0022] Jujube juice is ultra-filtered with an ultrafiltration membrane made of polysulfone with a molecular weight cut-off of 6000. The working pressure is 0.4 MPa and the temperature is 35°C. Nitrogen is intermittently fed into the ultrafiltration system to form a gas-liquid pulse flow, and the cycle is once an hour. , 1 minute each time; using a nanofiltration membrane with a molecular weight cut-off of 300-1000 polyethersulfone, the jujube juice ...
