What are solventless extraction processes primarily based on?

Solventless extraction processes are primarily based on the application of temperatures and pressures because these methods utilize mechanical forces and thermal energy to separate desirable compounds from plant material without the need for chemical solvents. This approach often results in a purer product, as the extracts are obtained without introducing foreign substances that can affect flavor, aroma, or safety.

For instance, techniques such as rosin pressing apply heat and pressure to cannabis flower to extract cannabinoids and terpenes while preserving the integrity of the original compounds. Similarly, ice water extraction uses temperature variations to separate trichomes from the plant material. These extraction methods are favored in many contexts for their simplicity, safety, and the cleaner end products they yield, aligning with the growing consumer demand for natural and organic options in the cannabis market.
