Concentrate
form of substance which has had the majority of its base component (in the case of a liquid: the solvent) removed
A concentrate is a special form of a substance, where one of the base components is mostly removed. The most common case is the removal of the solvent from a solution: Fruit juice concentrate will have most of the water removed. The benefit of this is that the concentrate takes up less volume, and weighs less than the original solution. This can save transportation costs. When needed, the solvent can simply be added again.
