New method: Cannabis extract using an espresso machine

Scientists from the University of Valencia in Spain have discovered a simple and effective way to extract extraction Cannabinoids From the cannabis plant using a home espresso machine.

There are Many methods To extract the active ingredients from the cannabis plant. Most of them take time and require effort - for example BHO, Dove, Or RSO oil - and are performed using solvents or alcohol.

Now it turns out that there is a very simple method of extracting cannabinoids from the cannabis plant - and it takes less than a minute. A team of scientists from the University of Valencia in Spain decided to check whether it can be used In a simple espresso machine Cannabis extract.

In an article to be published shortly in the International Journal of Analytical Chemistry and a copy of it, the scientists detail how they used the Essenza Manual XN2003 Nespresso simple espresso machine (which costs about $ 300)Amazon) To extract the cannabinoids THC, CBD, And CBN from cannabis supplied to them by the Narcotics Department of the Valencia Police.

Cannabis Extract

Sampling of 0.2 Cannabis was grinded and inserted into an empty coffee capsule (empty capsules can be purchased online, Here for example). The machine is filled with isopropanol (isopropyl alcohol), which it acquires Here For example) instead of water.

The machine was activated and in about 40 seconds a liquid extract was produced containing approximately 90% of the cannabinoids measured in the sample (THC, CBD and CBN). The method was tested in comparison to traditional extraction methods such as ultrasound extraction and was found to be nearly as effective.

"Our experience shows that this method for extracting the main cannabinoids yields good results, and demonstrates the variety of uses that can be made with a cheap and convenient espresso machine," the study concluded.

It is important to note that the extract is used for analytical purposes and laboratory use - not for consumption, since isopropyl alcohol is not intended for human consumption. You can use alcohol instead of 95% to get a liquid extract you can consume - but the extract will probably not be as effective as isopropyl. In addition to heating the flowers in advance, the essence will have no effect and also the consumption of cannabis flowers in their natural form. In order to "activate" the active ingredients, a process called de-carboxylation should be performed before the extraction of alcohol (Explanation here).

In recent years, the use of Cannabis extracts has been increasing, especially in the legalized countries where consumers have more access to such products.

In the state of California, for example, the market share of cannabis flowers from all the cannabis products sold in the country dropped from 90 in 2015 to 54 at the end of 2016, with the place of flowers taking cannabis extracts - especially cannabis oil.

The new trend in the world of flavors is Evaporation Cannabis oil 'Evaporation pens' (Vape Pens) - a sort of electronic cigarette that warms the essence and evaporates its cannabinoids and predators.

In contrast to the vaporization of Cannabis flowers in a classic Voyeurizer, which requires cleaning the burned residue from the device, the evaporation pens come with disposable cannabis extracts for more convenient consumption, one of the reasons for their increased popularity in recent years.

An even simpler method of espresso is the extraction of cannabis using an electric hair straightener (See here), But in this case it has not yet been examined whether this is a qualitative and complete extraction.
