Review of the Evolution of Ethanol Extraction for Cannabinoids

Ethanol continues to be a reliable extraction medium, thanks to its solvent properties and simple methodology. The process has significantly advanced thanks to technology, and nowadays, cryogenic ethanol extraction for cannabinoids is the primary method used for hemp and cannabis.

The evolution of cryogenic ethanol extraction for cannabinoids


Ethanol has been widely used in plant extraction for centuries, producing food colorings, perfumes, medicinal bases, and essential oils. It is less toxic than other alcohols, making it the second most popular solvent after water. As a result, several extraction methods have been developed over the years:

Maceration

A traditional approach to ethanol extraction, maceration involves soaking the plant material in ethanol. Then, the material is filtered to separate the solids and liquids and processed using evaporation to remove the solvent.


Soxhlet Extraction

This extraction method is used primarily for botanicals. First, the plant material; is packed into a column where ethanol is heated to produce vapor. Then, as the steam interacts with the material, extraction occurs, and the resulting solution is collected into a boiling flask.


Cryogenic Extraction

This is a relatively new extraction method involving cold ethanol. First, the alcohol is cooled from -20°C to -40°C. Then, plant material like cannabis is placed inside an extraction chamber, allowing it to soak in the liquid.

After extraction, the solution; is separated into the ethanol containing the cannabinoids and the biomass using centrifugal force. And finally, the extracted product is distilled and ready for use in edibles, oils, and other goods.

The benefits of cryogenic ethanol extraction for cannabinoids

Cryogenic extraction is slowly becoming one of the best and most popular ethanol extraction methods for cannabinoids. The process is highly reliable, offering numerous advantages you won’t find anywhere else:

·        Speed

Cryogenic extraction is a high-speed method that can be completed in hours. In addition, the process does not require extra steps, such as winterization, saving much time.

·        Safety

Cryogenic extraction has a lower explosion risk than other methods. It does not involve high-pressure systems, only utilizing ethanol, which has a relatively low boiling point.

·        Scalability

Cryogenic extraction is easily scalable and adaptable for any business. You can find extraction equipment in various sizes, allowing you to swap into a larger unit as your operations grow.

Are you looking for top-quality systems for cryogenic ethanol extraction? Consider working with a cannabis extraction solutions provider offering state-of-the-art equipment with easy-to-use features and onboard controls.
