Coffee oil contains some unhealthy substances, among which the diterpenes compound caffeol (cafestol) and coffee white alcohol (kahweol) will increase the concentration of triglycerides and cholesterol in the blood.

Studies have pointed out that drinking 60 mg of coffee oil a day is enough to increase the low-density lipoprotein cholesterol and triglycerides in the body. If the coffee bean contains 1% coffee oil, if you drink more than 6 grams of coffee, you can If you consume more than 60 mg of coffee oil, it is not good for your health.

We conducted an experiment using supercritical extraction technology to remove coffee grease.
