Abstract: An agent-delivery system for dispensing active agents of choice into ingestible materials of choice. The agent-delivery system includes a component for retaining the agent, typically in an extract form, which component is directed by the user into contact with an ingestible material. The extract is preferably water-soluble so that it may be dissolved into a fluid, generally a beverage of choice. The agent-retaining component may be a straw, spoon, soluble film, cap interior, or other suitable substrate capable of holding the extract. The extract may be applied to the retaining component in any of a number of ways, including by ink-jet spray equipment, or hand brushing, for example. Barrier sealants may be used to isolate the extract from the beverage until such time as the user wishes to enhance the beverage through agent introduction.
