<p>The package contains a minor no. of conventional chewing gum strips (A) plus a larger no. of sweetening or aromatising strips (B) which dissolve without leaving a residue. The base for (B) is pref. a conventional base for chewable sweets, esp. gelatine. (B) restore or alter the taste of chewed gum after elution of its flavour components, without increasing the amt. of gum in the mouth. Since (A) do not have to be discarded once their own flavour has been lost, disposal problems and waste of relatively expensive materials are minimised.</p> |
