Embodiment 1
[0040] Preparation of coffee extract:
[0041] Pretreatment: crush the roasted coffee beans and pass through a 60-mesh sieve to obtain coffee bean powder; according to the mass ratio of coffee bean powder: 50% alcohol 1:10, add solvent 50% alcohol for rough extraction and reflux The temperature was controlled at 85°C, extracted for 1.5 hours, and the extracted product was obtained. The extracted product was filtered with a double filter (200 mesh) while it was still hot, and then filtered with a 0.6um plate and frame; then the filtered extract was concentrated to a relative density ( 20°C) is 1.0686, the refractive index (20°C) is 1.3590, and the acid value is 4.5. After settling for 10 hours, take the supernatant and add 20% caprylic acid glyceride of the product quality, and stir evenly to obtain a mixed solution.
[0042] Molecular distillation: Put the above mixed liquid into the molecular distillation raw material tank, set the process parameters: vacuum degree 0.1mmHg, s...

[0046] Preparation of coffee extract:
[0047] Pretreatment: crush the roasted coffee beans and pass through a 60-mesh sieve to obtain coffee bean powder; according to the mass ratio of coffee bean powder: 50% alcohol 1:10, add solvent 50% alcohol for rough extraction and reflux The temperature was controlled at 90°C, extracted for 2 hours, and the extracted product was obtained. The extracted product was filtered with a double filter (200 mesh) while it was hot, and then filtered with a 0.8um plate and frame; then the filtered extract was concentrated to a relative density (20 °C) is 1.0766, the refractive index (20 °C) is 1.3670, and the acid value is 6.5. After settling for 12 hours, take the supernatant and add 20% caprylic acid glyceride of the product quality, and stir evenly to obtain a mixed solution.
[0048]Molecular distillation: Put the above mixed liquid into the molecular distillation raw material tank, set the process parameters: vacuum degree 0.15mmHg, scraper ...

[0052] Preparation of coffee extract:
[0053] Pretreatment: crush the roasted coffee beans and pass through a 60-mesh sieve to obtain coffee bean powder; according to the mass ratio of coffee bean powder: 50% alcohol 1:10, add solvent 50% alcohol for rough extraction and reflux The temperature was controlled at 95°C, extracted for 2.5 hours, and the extracted product was obtained. The extracted product was filtered with a double filter (200 mesh) while it was hot, and then filtered with a 1.0um plate frame; then the filtered extract was concentrated to a relative density ( 20°C) is 1.0846, the refractive index (20°C) is 1.3750, and the acid value is 8.5. After settling for 14 hours, take the supernatant and add 20% caprylic acid glyceride of the product quality, and stir evenly to obtain a mixed solution.
[0054] Molecular distillation: Put the above mixed liquid into the molecular distillation raw material tank, set the process parameters: vacuum degree 0.2mmHg, scraper spe...
