Coffee oil

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.

HOW TO CHOOSE THE RIGHT CO2 EXTRACTOR?

CO2 Extraction Machine Buyer’s Guide

As you can imagine, not all supercritical CO2 extractors are made the same.
For more than 30 years, we have customized many CO2 extraction machines (Tabletop CO2 Extractor) for many companies and university laboratories (1 lb CO2 extractor). Because each customer’s CO2 extraction process requirements are different, there are almost no identical machines.

How many liters of CO2 extraction vessel are needed?

The first factor that determines the size of the CO2 extraction vessel is the daily working hours of the plant, which determines the daily extraction batch. The vessel size of the CO2 extractor depends on the biomass to be processed per day.

How many pressure is best for your CO2 extraction process requirements?

The choice of CO2 extraction pressure is a changing factor. If the extraction pressure is too high, the useless substances in the plant will be extracted, such as wax and chlorophyll. If the extraction pressure is too low, the extraction time will be increased.
