Cannabis-infused drinks have exploded in popularity in recent years. Most grocery stores in the United States now offer a wide range of CBD-infused beverages. And licensed producers in Canada also offer THC and/or CBD-dosed beverages. Liquor companies are also looking at this potential growth driver, for example, Heineken with Lagunitas.
These drinks often sold in aluminum cans. They usually contain a plastic lining on the inside that prevents the beverages from having a metallic taste and reduces can corrosion to optimize shelf life. But when potted drinks are under pressure. The coating can attract tiny emulsified droplets of e cannabinoids and reduce the advertised effect of the drinks.
Our theory is that the cannabis particles, the droplets, will stick to the coating and cling to it. When you open your can for a drink, it will lose its potency, said Harold Han, founder and scientific director of Vertosa, a cannabinoid drink manufacturing company.
Because cannabis is not naturally aquaphile, making a drink with CBD or THC requires the use of a nanoemulsion principle that breaks down the oily compounds on a microscopic scale so that they can remain suspended in a drink.
Cannabis drinks using this technology have a faster effect than traditional edibles. They also have high bioavailability, as the body absorbs a higher amount of THC or CBD more quickly in this form.
Vertosa first noticed the problem when Lagunitas migrated its Hi-Fi Hops from cans to glass bottles in early 2019. “Then we thought, let’s test some can coatings. Let’s test our emulsions. “After conducting these tests, Harold Han and his team found that the loss of cannabinoids “was horrible.
