Have you noticed a spike in higher-quality botanical concentrates in the market over the past couple of years? Well, thanks to the development of biological, chemical, and mechanical technology, there’s a corresponding evolution in the production of botanicals. Praised by manufacturers, the most successful and high-quality method is the ethanol extraction method. To give you a better understanding, we’ll dive in and unpack what ethanol extraction means for botanicals and concentrates.
Extracting oils from plants is far from just squeezing them out like you would when juicing. Ethanol extraction involves introducing a solvent to separate the oils from plants; different plant oil extraction methods use specific solvents. As such, the ethanol production method uses ethyl alcohol (ethanol) while the CO2 method uses CO2 in its supercritical state.
In the ethanol extraction process, the ethanol and plant material, while separated, are brought to freezing temperatures, using commercial freezers, medical freezers, or dry ice. The two are then combined and mixed, which allows the cold ethanol to strip oils and other desirables from the plant material. The plant material is then strained, and the wash from this is filtered further. Once this filtering is completed, the ethanol is removed from the resulting concentrate, using low-temperature heat and vacuum for evaporation. This process allows up to 98% ethanol recovery, leading to very little waste.
Many manufacturers prefer using ethanol to extract botanicals from plants because it is:
The main difference between the warm and cold ethanol production processes is that the warm method requires a process called “winterization” in which the extracted oil is cooled to separate (then Filter) the plant lipids, waxes, and other impurities.
The cold ethanol extraction process begins with freezing the botanical material so that it does not dissolve into the ethanol. The cold ethanol production process is safe and suitable for both large and small-scale operations.
ExtractCraft products are designed with the everyday user in mind and keep the operation safe, economical, and straightforward, so you can focus on extracting your favorite botanicals instead of on complex workflows and formulas.
