additive

In foods, any of various chemical substances added to produce desirable effects. Additives include such substances as artificial or natural colourings and flavourings; stabilizers, emulsifiers, and thickeners; preservatives and humectants (moisture-retainers); and supplementary nutrients. Though many additives are harmless or even beneficial, others reduce nutritional value or conceal inferior raw materials or processing.

additive - A function f : X -> Y is additive if for all Z <= X f (lub Z) = lub { f z : z in Z } (f "preserves lubs"). All additive functions defined over cpos are continuous. ("<=" is written in LaTeX as \subseteq, "lub" as \sqcup ).
