The analysis workforce identifies unstable chemical substances, not terpenes, which are answerable for the odor of hashish

While that is the skunky aroma of cannabis traditionally attributed to terpenessays a research team, is to blame for a completely different connection.

After a March 22nd Press releaseA research team led by Byers Scientific, Iowa State University, and olfactory experts from Texas isolated and identified the volatile chemical they believe is primarily responsible for the skunk-like odor emitted by cannabis. According to the research team, 3-methyl-2-butene-1-thiol (321 MBT) is the main chemical responsible for odors that cause complaints from growers’ neighbors.

“By using a triangulation approach to analytical chemistry (i.e. SPME fiber, gas chromatography-mass spectrometry and GC olfactometry analysis), leaf wrapping study, and field observation, the research team was able to isolate, identify, measure and ultimately conclude the compound 3-methyl-2-butene -1-thiol (i.e. 321 MBT) is the main source of the traditionally unpleasant odor of cannabis, ”the team wrote.

Interestingly, the connection is that too The same volatile chemical previously reported to be responsible for the skunky off-flavor and taste in beer that had been damaged by exposure to light. Beer is usually sold in brown glasses to minimize that unwanted taste and aroma. As most people know, beer is made from hops that come from the same family of plants. Cannabaceaethan cannabis. The ironic part is that some cannabis growers have tried this Maximize the skunk odor That is now associated with higher 321 MBT levels.

Terpenes are the naturally occurring, volatile hydrocarbons that cannabis shares with the familiar, pleasant aromas of citrus and other fruits. However, the researchers stated that 321 MBT makes more sense to meet the “expectation of a sulfur component within the chemical profile of the cannabis plant emission”.

Finally, the team warned that other compounds in the facility’s gas phase emissions and atmospheric responses could significantly affect the perception and measurement of 321 MBT.

Companies have already tried to crack the code for odorless cannabis. In 2019, Ontario, Canada-based CannabCo Pharmaceutical Corp. partnered with an undisclosed technology company “Purecann”, an almost odorless variety of cannabis.
