Embodiment 1
[0044] Weigh 100 kg of ginkgo biloba dry residue, clean it, mix it with 200 kg of purified water and grind it into a paste with a refiner; place it in a hydrolysis tank, add 400 kg of purified water, adjust the pH to 4.6 with phosphoric acid, and mix well Introduce steam through the interlayer of the hydrolysis tank to raise the temperature of the mixed material in the tank to 42°C, add 9.1 kg of cellulase under stirring, and keep it warm at 42°C for enzymolysis for 100 minutes; then use a disc centrifuge with a centrifugal speed of 8000r / min, centrifuged for 20 minutes, and collected 540 kg of centrifugal supernatant; heated the centrifugal supernatant to 88 ° C, added 8.1 kg of activated carbon and kept stirring for 25 minutes, then vacuum filtered while it was hot, collected the filtrate and cooled it to room temperature rapidly, and then used 0.22 μm microporous filter membrane to obtain the filtrate; pump the filtrate into a vacuum rotary evaporator, and carry out vacuum ...
