Ethanol is a colourless volatile, flammable liquid which is produced by the natural fermentation of sugars. It’s considered a universal solvent due to having both polar and non polar properties.
Advancements in technology have allowed manufacturers to produce higher-quality cannabis products, while at the same time significantly improving their profit margin.
Let’s take a further look at the difference between cold ethanol and warm ethanol extraction.
With the popularity of cannabis extracts burgeoning, there remains a huge market for products produced using solvents to extract desirable compounds from raw cannabis plants. While hydrocarbons and CO2 are preferred solvents for many producers, ethanol remains a solid option for small-scale and high-throughput producers alike.
Types of ethanol extraction used in cannabis applications
These two types of extraction follow the same basic steps. But, because of the difference in the temperature of the ethanol, they will yield different results. Both can be carried out using a relatively simple setup without requiring specialized equipment. Here are the main steps involved:
Room temperature and cold ethanol extraction
Ethanol extraction has benefits and drawbacks over other types of extraction methods. But some of its pitfalls can be overcome by tweaking the type of ethanol extraction method used. For example, using cold ethanol will limit the levels of undesirable compounds that end up in solution. Opting for a warm ethanol process can provide a fuller plant profile, which may be considered beneficial for some products.
