Solventless extraction
An extraction method used to separate trichomes or certain compounds from hemp without using chemical solvents.
Solventless extraction refers to a range of methods used to obtain hemp concentrates or extracts without using chemical solvents such as ethanol, butane or propane. The compounds are separated mainly through mechanical or physical processes.
These techniques generally aim to collect trichomes, which contain cannabinoids, terpenes and other compounds naturally present in the plant. They are widely used in the world of cannabis and hemp concentrates.
Main methods used
Some of the best-known processes include dry sifting (Dry Sift), ice-water extraction (Bubble Hash) and hot pressing to obtain Rosin. Each of these methods is based on different physical principles but does not use chemical solvents for extraction.
Preserving plant material
Solventless methods are often appreciated for their simplicity and their ability to preserve certain compounds naturally present in the plant. However, the results may vary depending on the quality of the raw material and the control of the process.
A category of concentrates
The term solventless extraction is now widely used to distinguish certain concentrates from extracts obtained with solvents. Above all, it describes a manufacturing method rather than a particular level of quality.
