Embodiment 1
[0028] 1) The raw material of green coffee beans is softened or crushed conventionally, and the green coffee beans are extracted with a mixed solvent of 6# solvent oil and ethanol (the mixing volume ratio of the two is 1:1), and the extract is separated by adding water to obtain an ethanol-water layer and 6# solvent oil layer, and then the ethanol-water layer is filtered, concentrated, and solvent residues are removed, and then vacuum-dried to obtain the green coffee bean extract.
[0029] 2) Celery extract is prepared as follows:
[0030] (a) Wash the celery, cut it into sections, freeze it, and beat it into a slurry. Add cellulase for 120 minutes at pH=5.0 and 55°C, and then press the volume of absolute ethanol and the solution Add absolute ethanol at a ratio of 6:1; then reflux at 75°C for 2.5°C, filter after cooling, and collect the filtrate, concentrate the filtrate under reduced pressure to a relative density of 1.25 at 50°C to obtain the crude extract of celery;

Embodiment 2
[0042] 1) The raw material of green coffee beans is softened or crushed in a conventional way, and the green coffee beans are extracted with a mixed solvent of 6# solvent oil and ethanol (the mixing volume ratio of the two is 1:2), and the extract is separated by adding water to obtain an ethanol-water layer and 6# solvent oil layer, and then the ethanol-water layer is filtered, concentrated, and solvent residues are removed, and then vacuum-dried to obtain the green coffee bean extract.
[0043] 2) Celery extract is prepared as follows:
[0044] (a) Wash the celery, cut it into sections, freeze it, and beat it into a slurry. Add cellulase at pH=4.0 and 35°C for 100 minutes of enzymatic hydrolysis. Add absolute ethanol at a ratio of 5:1; then reflux at 85°C for 3h, filter after cooling, and collect the filtrate, concentrate the filtrate under reduced pressure to a relative density of 1.35 at 50°C to obtain the crude extract of celery;
[0045] (b) dissolving the celery crude ...
Embodiment 3
[0056] 1) The raw material of green coffee beans is softened or crushed in a conventional manner, and the green coffee beans are extracted with a mixed solvent of 6# solvent oil and ethanol (the mixing volume ratio of the two is 2:1), and the extract is separated by adding water to obtain an ethanol-water layer and 6# solvent oil layer, and then the ethanol-water layer is filtered, concentrated, and solvent residues are removed, and then vacuum-dried to obtain the green coffee bean extract.
[0057] 2) Celery extract is prepared as follows:
[0058] (a) Wash the celery, cut it into sections, freeze it and beat it into a slurry, add cellulase for 30 minutes under the conditions of pH=4.5 and temperature 65°C, and then press the volume of absolute ethanol and the solution after enzymatic hydrolysis Add absolute ethanol at a ratio of 4:1; then reflux at 95°C for 2 hours, filter after cooling, and collect the filtrate, concentrate the filtrate under reduced pressure to a relative ...
