Carbon Dioxide (CO2) extraction of cannabis is becoming more prevalent as the extract market grows with the spread of medical and recreational legalization. However, due to the historically underground nature of working with the substance, little true scientific experimentation and process development has occurred; even less has been published. Those new to the field have limited guidance.
The following is a compilation of the process learnings regarding selection of extraction parameters that Supercritical Fluid Technologies (SFT) customers’ companies who are currently working in the CO2 cannabis extraction field have shared with us. Due to the proprietary nature of each company’s specific process, the material here will be presented in a generic way that is applicable to the majority of processors.
