Scientists discover aluminum cans suck cannabinoids from infused drinks – firebird-cbdoil
Cannabis-infused beverages have become increasingly popular in recent years, and most grocery stores in North America now offer a wide variety of beverages infused with CBD – although these products are technically illegal in the United States. Legal weed companies and even traditional alcohol conglomerates are constantly working on new ways to monetize drinkable cannabis, but scientists have recently made a discovery that could derail this new market.
Beverage manufacturers often use aluminum cans to keep their costs down. However, scientists found that these cans are a particularly poor choice for weed drinks. Lining these doses, scientists claim, can actually leach cannabinoids from drinks and reduce their effectiveness.
Pot foods can be easily made by adding cannabis oil to a traditional food. However, the same trick cannot be used to make drinkable weeds due to the basic chemistry: oil and water do not mix. Manufacturers of infused beverages circumvent this by using nanoemulsion to break down cannabis compounds into microscopic particles that can be suspended in a liquid. This process also has the pleasant side effect of increasing the bioavailability of the cannabinoids, which means that a pot drink can work faster than an edible one.
However, the use of nanoemulsion can have a disadvantage. Most metal cans have inner linings that prevent the can from corroding, improving durability and preventing the drink from tasting of metal. Unfortunately, by the time an infused beverage is packaged, shipped, stored, and then sold in a store, the inside of a can may have absorbed most of the beverage's cannabinoids, rendering it ineffective.
"Our theory is that the cannabis material, the droplets, stick to and adhere to the liner," Harold Han, founder and CSO of the cannabis infusion technology company Vertosa, told Yahoo Finance Canada. "If you open the can for a drink, it will lose its effectiveness."
Han said that he first noticed the problem when the Lagunitas brewery switched its hi-fi hop cannabis drinks from cans to glass bottles earlier last year. "Then we thought we'd get some can liners," Han told Yahoo. "Let's test our emulsions." After performing these tests, Han and his team found that the loss of cannabinoids was "terrible".
Vertosa has now partnered with several can manufacturers, including Ball, Ardagh Group and Gamer Packaging, to try to develop a new can liner that absorbs less cannabis compounds. "It is up to us to find the solution," Han said. "You will always see a certain percentage of losses. But as long as you can handle that loss and plateau it is the goal. "
