Ferrero has launched a Tic Tac mint in the US that changes flavour in the mouth.

The company said Tic Tac Mixers are "dual-flavoured pills that change from one flavor to another as you let them melt in your mouth".

Todd Midura, category manager for the Tic Tac brand at Ferrero's US arm, said: "While the majority of the gum and mints category is focused on functional, breath-freshening benefits, we saw an opportunity to offer our consumers an unexpected surprise."

Ferrero has developed two products – cherry cola and peach lemonade.
