There is a clear key word when talking about current trends in chewing gum: NATURAL.
More and more products are launched under this claim (which of course does not only apply to chewing gum, but it is a trend in all types of food and even beyond).
One way to make a gum that is natural is using the right ingredients (natural gum base, natural sweeteners, natural flavours etc) but there is also the packaging! Some producers (not all) have this in mind and today I have read this article in Candy Industry mentioning that one of the leaders (Perfetti Van Melle) has launched a gum with an interesting cardboard packaging. I am sure we will se more coming this way. Congratulations!
