What It Means for Modern Brands
Extraction’s main goal is to concentrate on compounds such as terpenes and cannabinoids by removing them from the undesired plant compounds. Depending on the techniques utilized, this develops a particular flavor, scent, or effect.
Cannabis has been used around the world for literal ages, to Viking ships and ancient Mongolia. It was generally used for spiritual and medicinal purposes, including during childbirth and for toothaches. With increasing legislation at the State level allowing the general use of cannabis, more companies are starting up and developing their own methods and products.
Alcohol or Ethanol Extraction
One of the oldest forms of cannabis extraction is alcohol extraction using ethanol. With it, there is little chance of toxic residue being left behind and contaminating the final product. It can be used to extract a number of cannabinoids and terpenes, making it a good choice for modern use, as well. Ethanol is regarded as “generally regarded as safe” by the FDA, and it is an efficient and effective solvent.
Supercritical CO2 Extraction
Today’s CO2 extraction methods offer many advantages over historic cannabis extraction methods such as ice wax, bubble hash, and the full-melt dry sift. When utilizing the Supercritical CO2 extraction method, carbon dioxide is turned into a supercritical liquid by fine-tuning pressure and temperature. It creates an environment where differing weights of material in the plant solids can be removed. It provides a consistent method of creating cannabis extracts. Supercritical CO2 extraction also prevents any solvent residue from remaining behind in the final product, including any bacteria or mold that was in the plant material.
Blended Gases for Extraction
Using mixtures of gases for cannabis extraction have become popular because of the different products it can yield. Blended gases offer the best of each gas’s attributes and combine to create a product that has different components that each gas alone. For example, a butane-propane mixture keeps the pressure low and pulls out a large percentage of oil while producing a clearer product.
Due to the explosion of the industry, the technology used to extract cannabis has grown and changed quickly, as well. As the industry evolves, modern cannabis brands will need to keep up. Technologically, new developments happen regularly. In recent years, equipment has upgraded with commercial, hydraulic, and pneumatic presses allowing for high volume, high pressure extraction. Researchers discovered that an espresso machine could function as an extraction device, paving the way for people to have their own extractor at home. As things continue to advance, producers will need to monitor trends and keep their company poised to follow suit.
