Why does chewing gum lose its flavour?
Quick Answer
The sweeteners and flavourings in gum dissolve in saliva and get swallowed. What stays in your mouth is the gum base, which is designed not to dissolve and has almost no taste of its own.
The Full Story
A stick of chewing gum is mostly a gum base (a blend of resins, waxes and elastomers that gives it its stretch) mixed with sweeteners, flavourings and softeners. The gum base is made to resist saliva, which is why a piece can be chewed for a long time without falling apart. The sweeteners and flavourings, however, are water-soluble. Each time you chew, saliva dissolves more of them and you swallow them, so the flavour fades fast after the first burst. Your tongue also gets used to the taste over time, which makes it seem even weaker. Some manufacturers try to stretch the flavour out with coated or encapsulated flavour crystals that release slowly.
