Is prepared instant coffee a compound element or mixture?

Instant coffee is made from brewed coffee that has been dehydrated by removing the water. The process of dehydration can be done in a number of ways, including freeze-drying, spray-drying, and drum-drying.

The resulting powder is a mixture of coffee solids, including caffeine, coffee bean oils, and other compounds that give coffee its flavor. The powder may also contain added ingredients, such as sugar, cream, or flavoring agents.

When instant coffee is mixed with water, the coffee solids are rehydrated and the flavor of the coffee is released.
