  • Publication number: 20230248029
    Abstract: Disclosed are single-serving coffee containers in which nanoparticulate CBD, embedded or encapsulated in a hydrophilic thin film, is deposited in a lower portion of the single-serving coffee container below a packed bed of ground coffee beans. The container may, but need not, include a separator that separates the container into an upper portion containing the ground coffee beans and the lower portion containing the CBD nanoparticles. Disclosed methods of using such single-serving coffee containers include exposing the hydrophilic CBD thin film to hot water used in brewing a coffee beverage, thereby causing a carrier material of the hydrophilic thin film to dissolve or disintegrate, thereby releasing the CBD nanoparticles to form a CBD coffee beverage.
