How to Get the Best CO2 Extraction Method

CO2 extraction pressure

The extraction pressure has a significant effect on the yield. When the extraction pressure is small, the extraction rate is lower, and the extraction rate reaches the maximum when the pressure is 30MPa.

CO2 extraction temperature

The extraction temperature has a significant effect on the extraction rate. As the temperature increases from 40°C to 60°C, the extraction rate of cumin fruit oil increases significantly. After 60°C, the extraction rate no longer increases, but decreases slightly. The extraction rate reaches the highest when the extraction temperature is 60°C.

CO2 extraction time

The yield gradually increases within the range of 1h~2h for the extraction time period, and reaches a larger value at 2h. With the extension of time, the yield is basically stable.
